Flat Roof Replacement You Can Count On

It’s not easy to choose the type of roof you want if you’re looking to replace your existing one. However, there is one clear choice, especially if you have a flat roof, from all the options out there. – a spray foam roofing system.

Here, we’ll go over the main pluses of spray foam roofing and why it’s a great choice.

Here Are Some of the Benefits of a Spray Foam Roof Replacement

Easily Repaired

If they are minor repairs that are needed, you may not even need to call a pro. You can fix small punctures or cuts with a tube of exterior polyurethane caulk.

Fill the cut or puncture with caulking, texture it to match the roof, and voila!, you just repaired your roof yourself! Unlike other roofing systems – you don’t have to have a professional flat roof repair contractor make these minor repairs.

Easily Works With Your Drainage Configuration

If they aren’t installed properly, a flat roof can have serious drainage issues during heavy rains, which can damage your roof’s structure. Flat roofs have common problems that foam prevents.

You can get proper drainage with a foam roof by applying several layers with different thicknesses to make the water flow to the right areas for proper drainage.

By applying the foam strategically in this way, you can virtually eliminate the drainage issues associated with other flat roofing systems.

Saves Money

You will have fewer leaking issues with spray foam roofing. because it is seamless and has no gaps. It has no overlapping materials and zero seams.

This means it has a surface that is pretty much impermeable because of its membrane comprised of polymers.

This makes it a much more secure roofing system because you will have fewer issues and their corresponding costs from repairs and water damage.

Energy Efficiency

Spray Foam roofing is an excellent insulator. It will save you money due to its outstanding R values of R-6 to R-7 per inch. much better than fiberglass insulation.

This will save you money through your utility bills. You could save as much as 30% or more over other flat roofing systems. As a result, you should be able to pay for your new spray foam roof over about the first five years of its lifespan.

Spray Foam Roofing Contractors With Experience and Integrity

Weathers Storms Well

In high wind situations,  your roof and its materials are usually the most vulnerable components of your home. In high wind situations, metal roof panels, shingles and tiles can be blown loose and become dangerous being blown through the air at high velocity.

Spray foam roofing adheres to the roof because of its seamless application. Which means there isn’t anything to be blown off the top of the roof and traveling through the air.

Also, as other debris is flying through the air and hitting your roof, it will resist damage when it's struck by them. There is also less chance that you will experience flooding and water damage due to its ability to withstand storms.

By having greater resistance to these extreme conditions, you’ll save time and resources through insurance premiums and fewer claims.

Good For the Environment

When you tear off old roofing systems, they create a lot of waste that ends up in landfills or recycling centers.

Spray foam roofing can be applied directly on top of your existing roof, leaving little to no waste material. Also, you won’t ever need to completely replace your roof again.

You just periodically and routinely maintain the roof by using sealant on problem spots and you’re good to go.

You Can Walk On It

Spray foam roofing is very durable and safe to walk on. This allows you to have access to your roof, making you able to check on problem issues yourself if needed and have easy access to the vents, pipes, and ac units.

There are also no overlapping seams or materials, as stated earlier, that you can trip over. It's safer for homeowners and roofing contractors alike due to its smooth, textured, and even surface.

You Won’t Need a New Roof Again

As we’ve mentioned, spray foam roofs have long lifespans, they’re easy to maintain and less expensive to repair and update.

You can just apply an update to the membrane about every 20 years at around 50% of what it would cost for a new foam roof, unlike other roofing systems that need to be completely torn off and replaced when their useful life is over.

The cost savings involved with these two scenarios is substantial. You won’t have to spend your money on expensive roof replacements ever again due to their long lifespan and ease of repair and maintenance.

More Slope Than Flat

Flat roof systems are more low-slope than completely flat. They have just enough slope to make water move toward gutter and drains to keep it from ponding on the roof. There are several options for a flat roof available when you’re deciding on whether to replace your roof.

What we feel is the best solution, sprayed-on polyurethane foam, should be used more than it is and pushed more by roofers in the industry. There are several options if you’ve decided to replace your flat roof.

Here Are 5 Options for a Flat Roof

Modified Bitumen

This material is rolled on top of your roof’s surface in a single ply. Most previous installations were completed by placing it on the roof and then using a blowtorch to heat it. This poses some risks, so newer materials have been created that stick to the roof after they are peeled off, making it safer. It’s good for the environment due to its ability to reflect the heat and rays from the sun, which will lower your cooling expenses. However, it does have a major negative feature – walking on it can tear the material and cause scuffing.

Built Up Roofing (BUR)

This material is very affordable, which entices homeowners to use it often as everyone likes to save money. It has a nice, attractive look which usually has gravel on top covering the material. Its constructed of several layers, so it provides more than adequate insulation for your home. But, due to these multiple layers, it weighs more tan other flat systems,. which means you may have to make some structural additions to your framing or structure in order to support it, meaning you’ll have additional expense when choosing to install it. One other drawback is you should not be occupying the property while its being installed, interrupting your families routine and schedule. There is plenty of info to be found online regarding BUR roofing if you need it.

Sprayed-on Roof Coatings

Silicone is the material most often used for sprayed-on applications. And, because its sprayed onto the roof, it is seamless, making it work great in resisting moisture and deflecting the heat from the sun. Since it reflects the sun’s heat and rays, it lowers your utility costs, saving you money. Another big benefit is its contribution to the environment because its applied directly on top of the old system. No need for the occupants to be removed during installation and no need to tear off the old roofing and dispose of it before its applied. There are a few negatives, though – the biggest one being its price, as its more expensive than the other flat options. However, that should be expected from something of high quality with so many positives. Depending on your roof’s configuration and your location, silicone roofing will usually be the most expensive option to choose from.

Single Ply EPDM

It’s similar to PVC, because of its single ply, but the main material is not plastic, but rubber. Its extremely durable, but it has a few drawbacks. Adhesives are used to close the seams, which can make them vulnerable to the elements over time, letting moisture get through and causing maintenance and repair issues. Asa result, you will have to pay more attention to routine maintenance and minor repairs than some of your other options.

PVC

This material is very reflective and durable.  It is extremely water resistant, keeping moisture from pooling.  Lastly, the installation process is simple, making it one of the best choices for your flat roof. It may sound like it is similar to spray applied coatings because they do have a lot in common. The biggest difference from other materials, including sprayed-on, is that the seams can lead to failing. Glue or tape is used to connect the seams, and they will deteriorate over time.  This allows more water over time to enter your home than a seamless system would.

Light Colors Equal Cooler Temperatures

The idea behind cool roofing is the same as the reasons people living in hot climates wear light colored clothing. Here in the desert southwest, wearing light-colored or white clothing helps keep you cool. Its because light colors reflect heat and sunlight, whereas dark colors absorb them. Homes are similar to people. If your roof is dark colored, your home will be hotter than if it had a light-colored roof. During the hot summer months we experience here in the Phoenix area, a darker colored roof can reach temperatures as high as 150 to 190 degrees at their peak.  In contrast, a cool roofing system will peak at around 100 to 120 degrees.

A cool roofing system can reduce the temperature on the surface of your roof by as much as 100 degrees.  This will reduce the heat that is transferred into the interior below.  The attic space and ductwork under the roof will be cooler.  This will lower utility and maintenance costs and improve comfort inside.  It will also increase the lifespan of your roof and lower the urban heat island affect and associated smog levels in cities.

What You Should Know About Cool Roofing

Cool Roofing Materials

They are made of materials that reflect the energy and heat from the sun away from the surface of your roof. The materials for homes with low-slope roofs are typically bright white, however, there are other colors that are being made for more sloped roof applications. Cool roofing is highly emissive, which allows it to emit infrared energy away from the roof. Bare metals and metallic coatings usually don’t have low emissive abilities, which is one of the reasons they aren’t thought of as cool roofing materials.

Cool Roofing Benefits

Cool Roofing Costs

Initial costs for a cool roof are similar to traditional roofing materials. Some cool roofing materials cost less than traditional materials and some cost more. Cool protective coatings can be applied every 10 to 15 years, which can reduce, or eliminate, the need for expensive roof tear-offs and replacements. If you add these roof repair or replacement savings with an average 20 percent savings on utility costs, it makes a cool roof a money saver over the life of your property. You can also get rebates in some communities, in addition to energy and lifespan savings, from local utility companies for installing cool roofing on your home.

Experienced Flat Roof Installation Contractors

There are 2 two types of materials for low-slope roofing systems on homes – single-ply materials and reflective coatings. Single-ply materials are made of large sheets of pre-constructed roofing fastened together over the old roof and sealed at the seams. Reflective coatings are installed or applied over an existing clean, leak-free roof surface using rollers, sprayers, or brushes.

There are other materials available for sloped roofs in clay or concrete tiles. They stay cool by using certain pigments that reflect the sun’s infrared heat. There aren’t asphalt shingles or pre-coated metal roofing materials available in cool versions right now.

Be Aware

While they do have their perks, flat roofs have design and installation factors that can play into damages and performance issues. In the long run, you may end up with a shorter roof lifespan than you expect – here are a few tips for issues you should consider.

Top 3 Common Flat Roof Issues

Leaking

Among all issues a flat roof can experience, this is the most frequent by far. Usually caused by unnoticed ponding water after rainfall, only 48 hours are needed before leaks start becoming apparent. You should check for moisture buildup around seams and flashings around your roof. Clogged drains, chimneys, and skylights are also places where you’ll want to watch for moisture buildup. If any water gets under the membrane and into the sheathing of your roof, there’s a chance rot and mold will quickly start to grow.

Shrinking and Deteriorating Materials

A common problem for EPDM membranes is shrinkage – when rubber shrinks, it can pull down other objects like parapet walls or chimneys! This is more likely to occur on a large building or on a building where the membrane was not properly secured and installed. Keep your eyes out for signs of discoloration along with signs of shrinkage to spot problems before they get out of hand.

Damage Caused by Foot Traffic

The last major issue that commonly affects flat roofs and flat roof decking is caused by heavy foot traffic. Often done by HVAC contractors and other visitors who go on the roof, damage can be caused by dropping tools, tripping on fasteners, or otherwise puncturing the membrane and allowing moisture inside. After a company has been on the roof, be sure to inspect for any signs of punctures or other damages.

What’s Your Ideal House?

When people imagine a house, many picture a building with a pitched or A-shaped roof. However, this is far from the only option available for your home or business. One style to consider is a flat roof, which is a horizontal roof that is usually tilted at a very low angle.

Reasons to Choose a Flat Roof

People choose flat roofs for a variety of reasons. Some simply like the way they give a home a more modern look. Others appreciate advantages such as:

However, it is important to note that there are also disadvantages to living in a building with a flat roof. For example, these roofs require careful maintenance, or they can be damaged by weather and gradual wear and tear. They can also be prone to water pooling and flooding.

Before choosing a roof design for your home, it is important to be fully informed about your options. Our roofing specialists can help you review your choices when designing a home or constructing a new roof.

Flat Roofing System Options

Foam Roofing

Foam roofing is the most energy-efficient roofing material available, over 500% more efficient than conventional roofs. It’s the first intelligent roofing technology for flat and low-sloped roofs, combining insulation and roofing into one material. That means no roofing seams or multiple layers – eliminating the expanding and contracting and separating that allows water and microbes to seep in and damage your roof.

Each Mikku and Sons foam roof is custom installed. The foam is sprayed on as a liquid mixture, and within a few seconds will expand to up to 30 times its original volume.  It will become a watertight, seamless solid that custom forms to the roofing substrate. Take a look at the advantages of a Mikku and Son’s foam roof:

Don’t Neglect It

Some maintenance do’s and don’t’s and basic rules for taking care of a flat roof are common sense.  You would be surprised what some flat roof owners do to jeopardize their roof. The worst thing you can do is neglect it. Small issues can turn into big problems quickly.

How your roof is used and the type of material you have will determine how much maintenance it will need. The following tips will help you take care of your residential or commercial roof.

6 Important Maintenance Tips For Flat Roof Owners

Keep the Roof Clean of Debris

You should clean your roof during and after the fall season, especially if you have trees that can drop debris. Here in Arizona, you should always inspect your roof after monsoon storms. Strong winds can throw debris up on your roof, even from other properties.  You may not even know there is damage causing debris up there if you don’t take a look. Always keep your flat roof clear of organic debris that could cause punctures or residual damage.

Make Sure Equipment is Attached Properly

Make sure any equipment that must be attached to roof is properly attached without causing punctures to the roof materials. If possible, mount equipment on top of a platform to limit damages to the roof materials. If your material uses fasteners, make sure they are tight and secure.

Inspect and Clean Draining Systems

Check draining systems and clean out any debris. Make sure you have adequate draining for your roof, if you notice a lot of ponding water you may need better drainage, clean them, or possibly have an area that needs something to stop ponding water. Some spots that have ponding water need leveling to help the water flow to the drain system. Ponding water can cause a flat roof to deteriorate quickly, so once its detected, remove it as quickly as possible and make sure the drain systems keep it from re-occurring.

Don’t Cause Undue Stress to the Roof

Flat roofs will have issues with pressure from too much weight, such as too much heavy equipment for the way the structure of the roof was built, snow and ice weight, water weight or even random things on the roof that shouldn’t be there. You should have some sort of documentation from the builders and designers that specifies the amount of weight your flat roof can withstand. If there is an area that is not supported well and  too much weight exists there, the roof can eventually collapse, causing all kinds of damage and even jeopardize your families well being.

Do Not Neglect Your Flat Roof

If you haven’t had it inspected for some time, or have put off repairs that need to be done for some time, do not wait. Call a professional flat roof contractor to inspect your roof and give you advice on the best way to maintain or repair it. The number one reason flat roofs have to be replaced is due to neglecting the roof’s need for repairs and maintenance.

Do Not Have Hazardous Materials on Your Roof

Exposure can cause damage to the material or other damage to the roof decking. Some roofing materials can become damaged with other products that aren’t made for the specific type of roof you may have.
