Foam Roof Installation Contractors
In the Desert Southwest, spray foam roofing is a great solution for flat or low sloped roofs. But, the experts at Mikku and Sons Roofing (Phoenix roofing contractors since 2001 and extensively using spray foam) have found a lot myths and misconceptions about this roofing choice that a lot of their customers have been concerned about before taking advantage of this option.
In order to show consumers the value and versatility of spray foam, Mikku and Sons wants to shed light on several myths:
#1: SPF costs too much.
Spray foam roofing is very affordable compared to other options. The cost is about the same as a single layer of asphalt shingles. As a matter of fact, with the rising cost of oil, the expense of asphalt shingles (an oil-based product) is going up, while spray foam pricing has remained fairly constant.
#2: SPF isn’t durable.
Research has shown that properly applied roofing foam can last as long as 50 years when applied correctly and maintained by re-coating it on a regular basis. There are foam roofs that were applied over 40 years ago that are still holding up well.
#3: SPF is too toxic.
Spray polyurethane foam is just a type of plastic that has been altered slightly and has been used to make the millions of bottles that are used in the food manufacturing industry — bottles that are used for bottled water, soft drinks, ketchup, mustard, mayo and hundreds, maybe thousands of other products that are consumed in households throughout our country every day.

#4: SPF isn’t a good insulator.
Foam roofing is a great option for insulating your property or business from heat, especially on flat or slightly sloped roofs. The closed cell structure gives SPF one of the highest R-Values (thermal resistance) of all roofing materials that can be used on your property, and it makes it very moisture resistant as well as being highly fire resistant, which is great for insurance rates.
#5: SPF is not energy efficient.
Texas A&M University studied the energy use of its campus buildings before and after they applied Spray foam on its building’s roofing systems. They studied more than eight million square feet of SPF roofing on their campus, and found that their energy savings completely paid for the expense of Texas A&M’s SPF roof systems in three to four years.

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, a horizontal roof that is usually tilted at a very low angle.
At Mikku and Sons Roofing we're ready to construct and repair a wide variety of roofs. To learn more about the services we offer, call our Phoenix roofing crew at 623-465-1068.
Why Get 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:
- Low cost – Flat roofs are generally easier to design and construct that angled roofs. Depending on the materials you use, they can cost significantly less money to build.
- Accessibility – It is much easier to access a flat roof for maintenance or repairs. Some people with flat roofs even use them for gardens or other projects.
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 Austin roofing specialists can help you review your choices when designing a home or constructing a new roof.
Built-up Roof Membrane (BUR):
- Assembled in place using multiple plies of asphalt- impregnated felt bedded in bitumen.
- Asphalt or coal-tar is applied hot in order to merge with the saturant bitumens in the felt and form a single-piece membrane.
- The felt is laminated in overlapping layers to form a membrane that is two to four plies thick.
- The membrane is protected from sunlight and physical wear by applying a layer of aggregate (such as crushed stone or other mineral granules) embedded in the surface ply.
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. It’s sprayed on as a liquid mixture, and within a few seconds expands up to 30 times its original volume into a watertight, seamless solid that custom forms to the roofing substrate. Just look at the advantages of an Armstrong Foam roof:
- Tough, seamless construction
- Can be sprayed onto almost any surface including irregularly shaped roofs and uneven surfaces
- Tenacious adhesion – demonstrated in the most recent Florida hurricanes
- Moisture resistant – even when the membrane coating is damaged
- Inch-per-inch, the highest energy efficient roofing material available
- Extremely strong – yet ultra lightweight
- Proven longevity classifies it as a sustainable low-slope roofing system
- In most cases requires only periodic recoating for decades of service

Elastomeric/Plastomeric Roof Membrane:
- Sheet materials applied to the roof in a single layer.
- They require less on-site labor than built-up roofing and are usually more elastic and, therefore, less prone to cracking and tearing.
- They may be affixed to the roof with adhesives, by the weight of a gravel ballast, by fasteners concealed in the seams between sheets, or with mechanical fasteners that do not penetrate the membrane.
- Some types of elastomeric/plastomeric roof membranes include the following:
- A high-performance synthetic rubber compound applied in sheets ranging from 0.030 to 0.120 inches thick and joined at the seams with an adhesive.
- Vulnerable to attack by ultraviolet light; therefore, it is usually coated with a protective layer of chlorosulfonated polyethylene.
- Vulnerable to aromatic solvents and strong oxidizing chemical.
- It may be fully adhered to the roof deck or partially adhered, with aggregate ballast to prevent wind uplift.
EPDM (ethylene propylene diene monomer):
- The most widely used material for single-ply roof membranes.
- A synthetic rubber manufactured in sheets ranging from 0.030 to 0.060 inches thick and joined at the seams with an adhesive.
- Vulnerable to petroleum products and plastic roofing cement.
- It may be fully or partially adhered, or used in a protected membrane roof.
PVC (polyvinyl chloride):
- A thermoplastic compound commonly known as vinyl.
- Relatively inexpensive.
- PVC sheets for roofing range from 0.032 to 0.060 inches thick and are joined at the seams either by solvent welding or hot air welding.
- Vulnerable to ultraviolet radiation, petroleum products, and coal tar.
- It may be fully or partially adhered, or used as a protected membrane.
Chlorinated polyethylene and chlorosulfonated polyethylene sheets:
- Vulnerable to petroleum products.
- Not compatible with PVC.
- Highly resistant to ultraviolet deterioration and can be manufactured in light, heat-reflective colors.
- Used on roofs where aggregate ballasting is unacceptable for reasons of appearance or excessive slope.
- Vulnerable to petroleum products, hydro-carbons, and some chemicals.
- Formed into composite sheets with various other materials.
- Some are intended to be laid loose, others to be adhered to the roof deck or insulation.
Fluid-applied Roof Membrane
- Used primarily for domes, vaults and other complex shapes that are difficult to roof by conventional means.
- Applied usually in several coats using a roller or spray gun. When it cures, it forms a rubbery membrane.

Factors Contributing to Flat Roof Deterioration
- Hot sunshine on a roof causes the volatile ingredients of tar or asphalt to evaporate.
- The asphalt oxidizes and becomes brittle.
- The roof mat eventually loses its elasticity, the surface coating becomes checked and flakes off, exposing the felt below.
- Water can seep into a dry roof through cracks and cause a leak.
- This moisture can turn to ice in freezing temperatures and can cause the roof to tear or heave.
- A strong wind can drive rain into defective joints in the mat or parapet, can cause the roof to tear at loose seams and can cause the roof structure to sway.
- Expansion and contraction place strains both on the roof structure (deck and walls) and strain the flashings. These strains can cause the roof mat to tear and mortar in coping joints to crack, providing sources for water entry.
- As walls settle, extra strains may be exerted on flashings, or the roof may settle below the level of the drain pipe. This will either cause a backup of flood water, or a leak through the crack around the drain.
- Roof mats are not designed for extra accessories such as signs and electric wires, nor are they intended for regular foot traffic. Anchorage planks are spiked or lagged to the deck, piercing both the mat and the deck, causing serious damage.
- Pollutants, acids and saturated animal fats can potentially damage membrane roofing. Protection from these is provided through coatings and/or ballast covering.

Flat Roofing Comparison
Usually, a polyurethane foam roof costs about equal to a Built Up Roof (BUR) with underlying insulation. But, foam roofs are unique because they’re the only roof type that both insulates and protects against leaks with a single monolithic barrier.
There are a lot of flat roofing materials, but all are not equal in quality. An EPDM (rubber roof) or single ply roof, sealed either by tars or adhesives are not as high quality as a typical BUR roof. The reason is they usually last less than 10 years, while a higher quality BUR roof may last a lot more than 10 years. Usually, a BUR roof is built with a few semi-flexible membrane layers, and then water-proofed with water resistant modified bitumen.

Remember, coal tars are a known carcinogen (not as severe as asbestos – otherwise, this would be more widely known). Modified bitumen, however, comes from oils, refined at much lower temperatures than coal tar, and is a much safer substance. The fluctuating prices in the cost of a barrel of oil gets passed on to the roofing industry. As the costs of asphalt roofing materials continue to increase, and the cost of a high quality polyurethane foam roof remains more steady, that makes SPF or foam roofing more affordable for consumers.
Cost, of course, can vary due to a lot of factors, like geographic location, and size and type of the project. Prices might be estimated anywhere between $3-$12 per square foot, and this can be effected by several other factors – the quality of the materials used, the labor costs to install these materials, and any associated warranty, contractor insurance, or bonding costs which will get passed on to the customer.
Flat Roof Installation Contractors
Initial Cost Factors:
- Roof Size: for example, large projects are often cheaper per square foot due to installation efficiencies gained with economies of scale.
- Roof Penetrations and obstructions: if your roof has a lot of obstructions – skylights, pipes, and AC equipment for example, you can expect higher installation costs due to increased labor requirements.
- Materials Used: EPDM and Single ply roofs are cheaper materials that won’t last as long. Higher quality roofing such as polyurethane foam may cost a little more, but it will insulate more efficiently and could last the life of the building. In contrast, a roof, such as Tar & Gravel, with insulation will expense about the same as an SPF roof.
- Location: Is your property in a convenient local location, or will your contractor’s crews have to drive a significant distance to reach your property?
- Condition of Existing Substrate & Roof: Can the current roof membrane be re-used, or does it need to be torn off? Is asbestos or other harmful substances under your roof membrane that have to be dealt with? Is there dry-rot or other failing materials. Do drains, vents, skylights or other roof penetrations need to be replaced or repaired?
- Are you thinking of installing solar power or replace your vents & drains, etc? It’s a lot more cost effective to do all of this at once. What if if your solar power installers caused a leak in your roof, and neither contractor (roofing or solar) wanted to fix the issue because they each blamed the other. If you’re thinking of installing solar, now would be a good time to coordinate the two installations simultaneously.
Long Term Considerations
If you’re going to install a roof, it’s good to think about the long term cost impact. If you have decided to install a foam roof, the insulation factor can pay off big in the long run. Also, think about adding cool roof coatings; just by changing the color of a roof to something reflective can lower summer cooling bills by 30% or more. Medium Density Sprayed Polyurethane Foam Roofing conforms to a roofs corners and angles and usually has an R-Value around 6 to 8 per inch of thickness. In layman’s terms, one inch of foam is as effective as 6 to 8 inches of solid wood.
In reality, due to things like vapor trapping (foam forms a barrier), and the density of foam (it is light, but heavier than air–of course), foam can be 4 times more effective than fiberglass. If you have lived in an older, poorly insulated home, you know that heating and cooling bills can really get out of control with a poor insulation. This is just one final cost factor which should be considered when you’re comparing an insulated roof like SPF with other roofing materials, like EPDM, Single Ply, or BUR, with no insulation.

Some maintenance and basic rules for taking care of a flat roof, as in do's and dont's, are common sense, but you would be surprised what some flat roof owners do to jeopardize their roof or let happen to their roof. The worst thing you can do is to neglect it, because small problems turn into big issues rather quickly. Depending on how your roof is used and what type of roofing material you have will depend on how much time and effort you must spend on maintaining your roof. But, either way, these are some tips or rules that flat roof owners, whether residential or commercial, should keep in mind to help take care of your roof so it can help you take care of and protect your home or business.
1. Keep the roof clean of debris, especially if you have trees around your roof, clean during and after the fall season. Here in Arizona, with our often times violent monsoon storms, you should always check and inspect your roof after we've had one. Strong winds can throw debris up on your roof, even from other properties, and unless you get on a ladder and get up to inspect it, you wouldn't even know some debris may be up there causing damage. Always keep your flat roof clear of organic debris that could cause punctures or residual damage.
2. Make sure any equipment that must be attached to roof is properly attached without causing punctures to roof materials. It is good for some equipment to be mounted on top of a platform of some kind that can limit damages to the roof materials. If your material uses fasteners, make sure they are tight and secure.

3. 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.
4. 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.

5. 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.
6. Do not have hazardous materials on your roof. Especially having the roofing system getting exposed to those materials. This 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.
