Inspecting a Flat Roof

Inspecting a Flat Roof

Leaks Can Be Devastating

When you’re buying a new property, you have a lot to think about to prepare for your new home. Inspecting a flat roof before following through with the purchase is extremely important. Even though you may have owned a property with a flat roof in the past, it is still a good idea to inspect the roof and understand how to maintain it. Leaks can be devastating and expensive if they’re not repaired quickly after they’re found.

Serious Flat Roofing Problems To Look For



These are areas that look like bubbles or where the surface is uneven. There could be moisture trapped underneath the membrane, but more often, its a result of improper installation. Ask a roofing contractor if a particular blister on your roof will cause bigger problems.



This could mean their’s a poor structure or bad insulation installation. Even if the membrane was installed correctly, shifting or movement inside could cause a split in the flat roof’s membrane. If this is the case, the flashing in this area will usually fail too.



If the membrane looks like its shifted from it’s original position, it could be due to the slope of the roof being too steep for the type of membrane installed, poor adhesion, or thermal issues. This can contribute to ridges, splits and other roof problems.


Obvious Damage

When inspecting a flat roof and find that it has been punctured or shows other signs of obvious damage, you should bring it to the attention of your professional roofing contractor.



Some membranes have a tendency to shrink. You will see this as an issue if membrane seams look like they’re pulling against a penetration like a plumbing vent pipe, or if the membrane can be pulled away from the eave’s edges. You may also see “bridging” at angle changes such as parapet walls, against other walls, etc.

Things to Look When Inspecting A Flat Roof

On the Roof

If you don’t see any discolored spots or any other signs leaking inside, it is still a smart choice to have the roof inspected. There could be cracks beginning to form that will become bigger issues down the road. You’ll want to get these problems fixed before they cause any internal damage to the home.

One thing we would recommend is walking the roof to do a simple visual inspection. To be safe, make sure to be aware of where you are on the roof and never walk backwards. Make note of all the penetrations and don’t put any weight on any skylight covers, they’re not built to withstand significant weight. While you’re walking the roof, make a note of how it feels under your feet. If it feels weak, get off the roof safely and as quickly as possible and call a professional roofing contractor.

A leak on the roof could soak the insulation under the membrane. If it feels a spongy underneath you, you’ll also want to refer to a roofing contractor. This is also the case if you notice any water coming out of any part of the membrane.

Inspect Penetrations and their Seals

Next, you will want to look at all the penetrations and seals. A large amount of leaks start at penetrations and seals, which make up a very small percentage of the total area of the flat roof. Penetrations, things like pipes and flashings that ‘penetrate’ the roof, are usually enclosed by flashings made from some form of sheet metal. Inspect around these penetrations for deterioration and cracks. This cracking might not seem to be a big problem, but as moisture gets in, it will expand the crack until its large enough to cause a big leak. Seals are where two waterproof materials overlap, coming together in the same spot. Inspect these seals and make sure they’re smooth and still fully adhering.

In the Interior

You’ll want to check each individual room in the property carefully. Check the ceilings for any stains or discoloration. If the roof is leaking, you’ll find a dark colored ring forming around the water-saturated spot. If you see this, you should contact an experienced roofing contractor before moving ahead with your purchase.

Damage from a leak in one area doesn’t necessarily mean that the leak is located directly above it. Flat roofing systems have layers that might direct the moisture to other areas in the home, many times far away from the source. The damage could also be from a plumbing or AC leak or, possibly some other source other than your roof itself. Its also a possibility that the leak that caused the stain was previously repaired but the discoloration on the ceiling was not. However, to be on the safe side, the best thing to do is to hire a professional flat roofing contractor to locate the source of any leaks.

To Conclude

If you’ve finished your roof inspection and decide you need to hire an experienced commercial roofing contractor, make sure to get several bids to ensure that you thoroughly understand what really needs to be remedied. Also, if you get multiple bids, you’re more likely to pay a lower price for your roof repair. Your roofing contractor might also be able to help you extend your roof’s lifespan and give you instructions on what you can do for routine maintenance throughout the year.

Request Your Free Estimate

What’s the Average Roof Repair Cost?

Roof Repair Estimates

Got a roof that needs some restoration love, but trying to figure out how much it's going to cost before you make a decision? Most roofing contractors offer free estimatess. So you can easily compare prices between companies before committing to hiring a contractor. We would advise getting at least 3 free repair estimates to get a feel for what the average cost of your roof repair should be. But, if you're looking for a ballpark range, the cost to restore a roof in Arizona can range from $350 to $2,000+ depending on these 3 items:

1 – The type of roofing material

Your roofing material strongly alters the restore cost. For example, concrete tile rates about 3 times as much as heavyweight asphalt shingles. And clay tiles are slightly more expensive than concrete tiles, which comes from the Tile Roofing Institute. So, if you have tile, you shouldn't be surprised if the estimated cost seems a little higher than you're expecting. While it may cost more to repair, tile roofing lasts longer and is more fire resistant than asphalt shingles.

To make things a little more complicated, the tile on your roof imay not be available in the marketplace. During the economic downturn, many tile manufacturers shut their doors – and with them their proprietary molds. The molds impact the direction tile connects with each other and actually lay on the roof. This may require doing a larger part of tile in order to have a logical start and stop point.

2 – The scope of the restore

– How much of the roofing material is missing or needs repair?

– How big of an area is required to be repaired?

– Is there any water damage from the faulty roof?

– If you have tile, does the older underlayment require repairing?

Answers to these questions( and others) will determine the needed supplies and amount of time required to do the repairs.

3 – Who actually does the roof repair

This is why we strongly recommend getting at least 3 free bids. You need to get a feel for :

– The character of their workers, especially if they're using subcontractors.

– The warranty they offer

– How long it takes them to do the job

– Whether or not they will haul away the damaged roofing materials

– Whether they're licensed and insured or not (NEVER hire an unlicensed roofer–unless you are trying to void your roof's warranty.)

Roof Repair Contractors

When you get estimates, don't just jump at the cheapest one, because how long they've been in business matters. Some say the best way to selected a roofing contractor is to find at a 10 -year-old yellow pages volume. If they're listed in that volume and they're still in business, they should be on your short list of contractors to use. Then, carefully check each bid to see if you're getting apples to apples services. One contractor may skimp out on important work to give you a lower bid.

Once you get a few repair approximations, you might feel like replacing your old roof is perhaps more cost effective in the long run. Once you've chosen your roofing company, have that conversation with them and determine what the best and most cost effective option will be.

Roof Damage Repair: What To Look For After Big Storms

Roof Repair Contractors

When it comes to your roof, there is a variety of ways that weather events can incur damage, even in moderate storms. For homeowners, one of the most important things to remember when a storm has passed and assessing roof damage repair is that the absence of water leaks in the home’s interior doesn’t guarantee that the roof has escaped any needed roof damage repair. Whether the storm brought rain, wind, and/or hail, doing an assessment as quickly as possible can start the repair process before more damage is done to the roof.

Here are 4 things to look for:

1) Look for downed power lines – The most dangerous residual effect of high winds is downed power lines, so look for those first. Make this assessment from as far away from the lines as possible for safety purposes and immediately report any issues to your electric utility.

2) Evidence of roof damage repair on the ground – The first step to take is to do a walking inspection around the grounds of your home. Look for all types of roofing materials including shingles, fascia, and flashing that may have been blown off of the roof. Take a look around the mouths of all of your downspouts as well to see if any roofing materials came loose and were carried down by the drainage system. You may also be able to assess any separation of the shingles from the deck by inspecting the roof’s edges, which can be caused by storms with high winds. Remember that finding one broken shingle on the ground may mean that there are many more broken pieces that evidence roof damage repair that are still on the roof.

3) Check surrounding trees for missing branches – Many areas of a roof may not be visible from the ground, but if you have trees that are missing branches that can’t be found, they may be up there.

4) Check the attic for leaks – Many leaks start small and grow over time, meaning that you may not see water damage unless you’re up in the attic. Look for damp insulation and inspect the areas around the chimney, the vents, and any other apparatus that penetrates the deck.

Roof Repair Companies

If you come across any evidence of roof damage repair during your inspection, there is a high likelihood that repairs are in order. Be sure to document what you have found and relay all details to a professional roofer. This can facilitate a quick and efficient repair process that re-establishes the protective capabilities of your roof prior to the arrival of the next big storm.

Keep Your Roof Ventilated

Phoenix Roofers

To help keep ypour roof healthy, proper ventilation is key. Proper ventilation extends the life of your materials – it keeps them cooler in the heat of the summer and warmer in the cool of the winter. It will also keep moisture from forming in your attic, which can harbor all kinds of nasty pathogens , putting you and your family's health at risk. Also, not properly venting your roof can be an expensive problem to solve after the fact, so make sure you ask your roof installation contractor about how your roof and attic will be vented during the installation process.

How Vents Help

Attics need fresh air to breathe and stay healthy ust like we do. Installing the proper vents can accomplish this. You're going to have two types of vents – intake and outlet. Intake vents are installed lower than the outlets so that a sort of vaccum is created that takes fresh air in the intake vents and circulates it out at the higher outlet vents. This creates a constant air flow that keeps fresh air circulating throught your attic, allowing it to breathe and keeping your materials healthy.

Roof Repair Contractor

How to Figure the Right Ventilation

It is possible to have too much ventilation, so determining what you need for your particular roof is important. You need the exact amount of ventilation in order for your roof to be as energy efficient as possible. You need to know where the vents need to be placed and what size vents you're going to need. You will need to hire a professional, licensed roofing contractor to configure the correct vents and locations you need.

Checking For Ventilation Problems

Look for these signs that your attic may not be properly ventilated:

  • Moisture on the underside of the roof or rafters
  • Any kind of mold growth
  • A feeling of higher humidity in your attic
  • Rusted nails in the rafters and trusses
  • Water stained wood of any kind

If you see any of these issues or signs, you should call a professional, licensed roofing company as soon as possible to inspect your attic and roof to give you a solution to the problem. Your family's health and the lifespan of your roof could depend on it.

How To Handle Emergency Roof Repair

Emergency Roof Repair

Would you know what to do if a tree fell on your roof in the middle of one of our violent monsoon storms? You depend on your roof to protect everything inside your home, but what if high winds ripped it apart in the middle of the night? Who would you call and what would you do?

Here are 4 things you should know to help you get through this scary situation:

1 – First step in emergency roof repair

Once the roof has been damaged, its going to probably allow some water to get through to the underlayment and possibly into your home. The first thing you need is some sort of protective cover or tarp to keep the damaged area from continuing to be exposed to the elements, and hopefully, to keep any more water damage from happening. Most of the time, unfortunately, you'll have to wait until the the weather subsides to get a company out to cover the damaged area until repairs can be completed.

2 – Situations that need immediate roof repair

Mother Nature can definitely wreak havoc on roofing systems. Winds over 50 mph, which can be quite common during our monsoon storms, can tear shingles off the roof and move loose tiles which exposes the underlayment and substrate of your roof. This is wear the real damage occurs. Tree limbs of trees close to your home can whip in the wind with branches raking tiles or shingles off your roof. Tree limbs can literally be knocked off trees and poke holes in your roof by falling on it. And, sometimes, lightning can actually strike your home, blowing a hole right through your roof.

Roof Repair Contractors

3 – How do roofers handle emergency calls?

Roofing contractors have to protect their employees, first and foremost, so don't expect an emergency roofing company to run out in the middle of a violent storm and immediately solve your problem. They will usually wait until the storm subsides, then handle as many of their emergency calls as their schedule and crews will allow. There's not much any roofing company can do in the middle of a storm with high winds and lightning. If the emergency repair is caused by a fire, the roofing company has to assess the structural integrity of the property before placing their crews on the roof, to make sure it can support the crew and equipment needed to do the job.

4 – What should you, as the homeoner, do?

The first rule is – don't panic. the damage to the roof has already happened and there's nothing you can do about it except try to protect your valuables inside until the damaged area can be covered somehow. Contact a professional roofing contractor and your insurance provider as quickly as possible. Once the damaged area has been secured, take your time to choose the right roofing company for the job and to consider your repair options.

Two other words of advice. First, be careful of storm chasers. The fly-by-night crews and companies that come in to areas hit by storms and pressure homeowners to get their roofing problems fixed ASAP. They're probably not licensed or insured and they won't be around if you have any problems with any repairs you have them do if they don't hold up down the road. Second, never, ever, ever try to go up and try to fix or assess damage yourself, especially in the middle of a storm. No sense makinng the problem a hundred times worse by adding a trip to the emergency room for someone in your family on top of the roof damage.

If you do have an emergency roof repair need, give us a call at (623) 465-1068. Count on Mikku and Sons Roofing and Repair to help you through your options and solutions.


Questions For Your Roofing Contractor

Roofing Contractors

The roof on your home and business is a significant investment. You need to learn as much information as possible about any roofing contractors you hire to do installation or repair work on your roof. Although there are a lot of specific questions about your particular project you'll need to ask, this is a good list of questions you should ask every roofing company that interviews for your business.

1 – First some common sense. You need to have your contractor's license number so you can do some research at the Registrar of Contractors website/office. they will have all complaints, if any, posted about the company that have been filed in the last 3 years. You can also find out if their license is in good standing, the amount of their bond, if their license has ever been suspended and when it expires. You can find the name of the owner and how long they've had this license. All key information that tells you you're dealing with a real, reputable contractor.

2 – Ask what type of experience and other information about the crew that will be working on your property. How many crew members will there be? How much experience do they have? Have they been working for the contractor for some time or are they new? Will the estimator be part of the crew and follow up with them after the sale is made and they begin the work?

3 – Make sure you get a copy of their liability and workman's comp insurance. They should be able to give you the name of their insurance agent, who can then send you a copy of their certificate of liability and insurance limits. Having properly insured workers on your property is of the utmost importance.

Roofing Companies

4 – Make sure you find out what type of warranty you're getting for the work they do. Get it in writing and ask to see a physical copy of the warranty. If they just give you something verbally tell them to keep on walking.

5 – The materials they use should also have a warranty. Ask what type of warranty they have and, again, ask to see that warranty in writing.

6 – Will the estimator or owner be inspecting the project after its finished? Make sure a final inspection is included in your project and that you have the right to be present for the inspection.

7 – How long do they estimate the project will take and can you get some kind of hard estimate in writing? Make sure you have a solid start date and a good hard estimated completion date before they start their work.

8 – What are the hours and days the crew will be working on the property? What time do they begin their work each day and what time do they call it a day. Do they just work on weekdays or will they be including any weekend work in the project?

9 – Last, but not least, what happens when it rains? How do they cover the project and what type of delays should you expect if the weather doesn't cooperate during the project. Especially if your work is being done during our volatile monsoon seasons, you'll need to have some clarity on this so you know what to expect.

Here at Mikku and Sons Roofing and Repair LLC, we believe in thoroughly educating our customers and making sure that every question they have about us or their particular project is answered to the best of our ability. Our quality work and clear communication with our customers during their project is one of the reasons we get so many referrals of friends and family from our past customers.

Watch Out For Roofing Scams

Roof Repair Estimates

Now that we're coming up on the Summer and getting closer to the monsoon season, Arizona residents need to be wary of the many roofing scammers that invade our communities every year. Finding a reputable roofing company can be hard enough, without having to worry about someone ripping you off in the process. You have to be diligent and wary of contractors that present themselves as professional roofers, but don't have the proper insurance or credentials, only going after your hard earned money.

Here's an example of a roofing scam that bilked 27 homeowners in Texas out of thousands of dollars: Texas roofing scam. In the case these unscrupulous individuals stole over $100,000 from these unsuspecting homeowners by approaching them after storms, when the owners were desperate for repairs, and sometimes brought their baby along to seem like they were a trustworthy couple that was eager to do hard work. A little research by the homeowners would have shown them that this company had an F rating with the Better Business Bureau and were ignoring many complaints registered with them instead of answering and solving them.

Roof Repair Cost

So, how do you protect yourself from these scammers?

First, make sure you do your homework on any contractor before hiring them and especially before giving them any kind of money for doing the work. Request that they present their contractor's license and check their standing with the Registrar of Contractors. Ask how long they've been in business and verify their answer online. Check if they have a solid website that shows they're legitimate. Look and see if they have a listing on any of the consumer sites like Yelp, HomeAdvisor and Angies's List and check their testimonials and ratings there.

Also, make sure you check that they have the proper insurance in place. The worst thing you could do is contract with someone without proper insurance, then have them have an accident or damage your home, leaving you with extensive medical or repair bills without coverage. You can see a previous blog post we wrote on this subject here: Roofer's Insurance.

Finally, ask for references from satisfied past customers and call them to verify that they were happy with the roofing contractor's service, communication and timely completion of the job.

Roofer’s Insurance is Important

Roof Repair Estimates

When you're doing your due diligence and research into the right roofing company for your job, whether residential or commercial, make sure you make the roofer's insurance a part of your questioning. Hiring a company with inadequate insurance could make the difference between a positive experience and a disaster. 

Sure, they need to be affordable and fit your budget, and everyone knows you need to question the background of the roofing contractor you're hiring by asking about their credentials, making sure they have current licenses, their experience and making sure you get references from past customers. And don't forget to check their standing with the Better Business Bureau.  But, maybe even more important and equally as vital, is making sure they carry adequate general liability insurance and workman's compensation insurance before you hire them.

General Liability Insurance

General liability insurance covers the roofing contractor if their's a claim that includes property damage, bodily injury or harm, and any personal injury that happens as a result of some action by the roofer. If an accident or something happens on the project that causes a lawsuit, the insurance would be available to cover the roofing company, and you as the homeowner or business owner, if a claim needs to be paid. As the owner that hired the roofing company, you don't want to be involved in a lawsuit and paying for something that wasn't your fault just because you own the property.  This is important for you as the owner because you don’t want to be responsible for something happening on your property that is not your fault.

Roof Repair Cost

Workman's Compensation

Workman’s Comp insurance compensates with money and medical benefits if any employee or subcontractor of the company you hire is injured while performing their duties on your project. If the roofer you hire, or any of their workers, were to get injured, they would file a claim for workman’s comp to replace their wages instead of suing the roofer or you, the homeowner or business owner.

When you're hiring any type of contractor, to fix or replace your roof or any other type of service, its critical that they have adequate amounts of both these types of insurance. 

If you hire us at Mikku and Sons Roofing and Repairs, you can rest easy, because in addition to years of experience, great customer satisfaction and referrals and an outstanding rating at the Better Business Bureau, we always make sure that we, and by extension you, are covered completely with the right types and amounts of insurance. 




Your Roof’s Five Biggest Enemies

Emergency Roof Repair

Hiring the right roofing company can make a world of difference for your home or business. Knowing the main reasons you're going to need to hire a professional roofing company can help you hire the right one for the job. Here are the five biggest enemies to the health and condition of your roof:

1 – Trees and Their Branches

Trees are beautiful and must-have additions to your homes landscaping for their aesthetics and shading possibilities. They will give your home fantastic curb appeal and possibly help you lower your cooling bills, but, they can also be  a major problem for your roof if they're in the wrong location. If they're too close to your home, a branch being knocked down or even being scraped across your roofing material in a storm can inflict serious, expensive damage. In severe storms, the entire tree could fall on top of your roof. 

They also drop a lot of organic material, like leaves, pods and small branches, that can cause problems by clogging gutters and causing standing water after rains. If you don't clear the material on a regular basis, the materials can decompose and break down the roofing materials, leading to leaks.

2 – Roof Leaks

A leak itself is, of course, one of, if not the biggest problem. There's a lot of reasons leaks can happen – poor installation, water standing in areas, busted tiles and cracked shingles, failing underlayment, flashing problems and more. There's no limit to the areas of your roof that these issues can occur. 

Water can flow from one location to another, making it difficult at times to determine exactly where a roof leak is originating. The best thing you can do is hire a professional roofing contractor Like Mikku and Sons Roofing and Repair to discover the source. They can find the leak's source and make the necessary repairs to stop it and prevent it from happening again.

3 – Poor Ventilation

Air needs to flow through your roof freely to prevent heat, pressure and humidity from building up, causing stress to the materials. You should never completely block the air flow into your home through your roof.  During installation, sofits, vents and other means need to be installed in the proper locations to ensure that your roof will always have proper air flow through your attic. 

Shingle Roof Repair

4 – Pooling or Standing Water

During installation, a certain pitch or slope needs to be used to make sure water flows off and away from your roof to avoid any pooling or standing water issues. Standing water, whether caused by poor installation or some sort of obstruction, like tree debris, can be a major issue for your roof. Water is heavy. If there's a lot of it pooling on your roof, it can put a lot of stress on the support structure, along with, if its not removed, helping to decompose the construction materials and making its way into existing cracks, creating leaks. 

5 – Poor Initial Installation

When your home is built, or your roof is replaced, it needs to get off to its best start by being installed correctly. If not, you'll soon see loose shingles, broken tiles, decaying underlayment and other items that will start causing leaks. Choosing the right roofing company to complete your installation is one of the most important decisions you'll make for the construction and durability of your home or business.

Make sure you do your homework before hiring someone. Check the company's reputation online and check their standing with the Better Business Bureau and Registrar of Contractors. you'll have the peace of mind knowing that a quality, professional contractor has installed your roof.
