What Is The Coating For A Foam Roof

How Long Will My Spray Foam Roof Last? [Whiteboard Roofing]

Foam roofs are installed by spraying a closed-cell polyurethane foam onto the existing roof surface. The foam adheres to the roof and forms a continuous barrier that is seamless and waterproof. A foam roof is a monolithic roofing system that provides superior protection against water infiltration and UV rays.

Foam roofs are also energy efficient, reflect heat away from the building, and can last for decades with proper maintenance.

Always Take Into Account The Expected Roof Lifespan Of The System Youre Considering

When you replace your commercial roof, you want to get a long roof lifespan on your new roof. Unless youre planning on tearing down the building soon, you dont want a system that will only last a few years. As you consider multiple systems for your building as you should take into account the roof lifespan of each of them. Some systems are inexpensive or provide great results, but only last for short periods of time.

How Much Does A Recoat Cost

The average recoat will cost about 1/3 to 1/2 of the original installation cost in todays dollars. The cost can vary depending on the following:

  • the distance from the contractor
  • how many repairs need to be done before the recoat
  • how long of a new warranty is desired

Performing preventative maintenance annually ensures your recoat will be on the lower end of the recoat price range.


*This is a general cost. There can be many variables that increase/decrease this amount

The point Im trying to make is that once you have a spray foam roof, its basically a maintenance item. A foam roof is more cost-effective than a traditional roof that needs to be torn off and replaced after its warranty is over.

The Basics Of Spray Foam Roofing

In spray foam roofing, the A and B components of SPF are blended and applied directly onsite with a specialized spray foam rig. The two chemicals, which are housed in separate containers, are pumped through high-pressure hoses to a mixing gun at a temperature of 115-130°F. To ensure a successful application, the proper amount of heat and pressure is imperative during the installation process.

As the foam cures, it solidifies to form a durable, seamless, lightweight, and waterproof membrane. SPF provides the highest R-value of any commercial roofing material and is suitable for use in nearly every type of climate.

Your Asphalt Roof Was Damaged From A Storm

Foam Roof FAQ

The weather where you live and the kind of storms your roof faces factor into how much wear and tear it goes through. But that isnt the only thing you have to worry about when it comes to weather.

This may seem obvious, but heavy storm damage will also lead to a roof replacement. If high winds come through and rip up your shingles or a tree falls on your roof then clearly youre going to need a new one.

If you have a metal roof system, then hail damage to your metal panels will lead to a replacement if the integrity of the metal is compromised. But for an asphalt shingle roof to be replaced from hail it has to cause damage to the soft metals that are on your roof.

Whatever kind of storm damage your roof has, its important to know if your roof is covered. Read this article on replacing your roof through homeowners insurance.

Foam Roof Option Seems Attractive Be Careful With Hiring

Q:We would appreciate your advice regarding our San Francisco home’s roof.

We have a 1915 Edwardian with a flat tar-and-gravel roof in one of the “sunny” San Francisco neighborhoods. We’ve had the home for a dozen years, and while we don’t know the date of the last roofing job, my husband thinks it’s time to reroof.

I would like some insulation on our top floor – insulation seems an afterthought in the house as a whole – and my husband is thinking of installing tubular skylights called Solar Tubes to bring light into the two north rooms of the house. There is some blown-in insulation – not sure how extensive because the access to the attic is via a small space I can barely poke my head into.

Last, we’ll add a solar-energy system, although we are not sure when. We’ve gotten several roofing-only quotes, most for typical tar and gravel, and find it hard to differentiate how the work is different from one to the next, except for a quote from a company that will do a “foam” roof, claiming it is superior and adds an R insulation factor, negating the need for insulation above the ceiling.

Here are my concerns:

— We’ve not heard you mention foam roofs and are wondering if there are downsides we should be aware of.

— What questions should we ask to determine whether one roofer is using a better method or materials than another? Are there warranties or items we should insist on?

Slate Roof Average Lifespan

Slate is a type of natural stone used for roofing. Unlike clay or concrete tiles, slate roof tiles are made exclusively of quarried and hewn stone pieces, without any processing or fillers. Slate is one of the most difficult roofing materials to install, making it more expensive to install or replace.

However, slate is also considered the most durable of all roofing materials. If properly maintained, a slate roof could last the entire lifespan of your home.

The average lifespan of a slate roof is 100 years or longer depending on maintenance.

Finding The Right Contractor

Does Spray Foam Stop Roof Leaks?

For those considering an SPF roofing system, take the time to properly vet potential contractors. Request to see job references, industry certifications, product samples, case studies, etc. In some cases, a contractor may be able to arrange a roof walk on a project they recently installed.

Blowing Agent Climate Impact

Most closed-cell spray foam is now formed using hydrofluorocarbon blowing agents that have high global warming potential, partially or completely offsetting the climate benefits of the energy savings they can offer. In the United States, HFCs are scheduled to be phased out by January, 2021. A few spray foam suppliers have started supplying spray foam blown with hydrofluoroolefin blowing agents without this problem as of early 2017.

How long can spray foam be exposed?

It is recommended to be away from your home at least 24 hours during and after spray foam insulation has been installed because it will emit strong vapors and odors.

How long does spray foam take to dry?

Spraying a mist of water on the substrate or/and between layers of foam can speed up the curing process. Typically, it can take between 5 and 60 minutes for the foam to become tack-free. Full cure may be reached in a time range of about 8 to 24 hours, depending on the product and site conditions.

Does foam shrink in heat?

Foams, all of them, expand and contract due to temperature as do pretty much all materials. Some materials even expand and contract due to moisture changes who knew? Anyway, when foams are hot they get bigger. When they are cold they get smaller.

Noticing Signs Of Uv Damage

Even though foam roofs typically hold up very well under UV rays because of their seamless application , the sealant layer does take a beating from UV radiation over time. And, once UV rays have penetrated the outer coat of sealant, they can degrade the underlying layers of foam and cause leaks.

At that point, youre potentially facing the much more expensive project of replacing your roof.

Here in Phoenix, UV damage is an ever-present threat to your roof. When in doubt, we recommend calling us to schedule your checkup. We can assess how good your sealant layer is looking, and whether or not your roof needs to be re-sealed.

Youre Noticing Yellow/orange Foam

How Long Does Spray Foam Roofing Last?

Yellow or orange discolorations are signs of water damage and should be taken very seriously.

If you notice yellow or orange spots, these are either a sign that you didnt monitor the roof regularly enough, that you missed a hole during your last inspection, or that you missed your scheduled recoating.

Seeing yellowing is usually akin to a death sentence for the part of the foam roof that its on.

First, youll need to have the whole area torn up to repair any water damage, and then youll need to have new foam installed.

Expect to see yellow or orange spots on your roof at between 15-25 years, depending on the quality of care youve taken.

Factors That Impact Shingle And Roof Lifespan In Florida

The biggest contributor to how long a roof lasts in Florida is how much maintenance you do throughout the year. Remember, the shingles themselves are exposed to the elements every day. This means there will always be minor issues that need fixing.

Staying on top of routine maintenance like fixing leaks and replacing missing or cracked shingles will help keep your roof in good condition longer. If you put off repairs or ignore minor issues, you wont just increase the cost of those repairs youll also cause the materials to break down faster, shortening your roof lifespan.

  • How Long Can I Expect
  • Many clients ask a similar question about the longevity of their new roof shingles. How long are they expected to last? What could decrease the life expectancy?

    Some less-than-reputable roofing contractors are telling customers around St. Louis that silicone commercial roof coatings will last 50 years. However, our experience and the research proves otherwise. Our team sees silicone roof coatings lose their efficacy on a regular basis.

    Which is better for roofing silicone or elastomeric?

    Silicone roof coatings tend to collect dirt and debris easier than other roof coatings. If you need to apply another coat, you have to use a compatible silicone-based coating.

    Compacted memory foam mattress trick

    Foam roofing is easy.

    All you need to do is keep it clean.

    Sweeping several times a year will have a significant impact on the performance of your roof.

    After the first recoat, feel free to hose the roof down instead of sweeping it.

    Finally, do your best to decrease traffic on the roof and keep any furniture far away.

    This will avoid early compression of the foam itself and degrade the foams compression resistance.

    What Is A Spray Foam Roof

    Spray polyurethane foam roofing, also known as spray foam roofing, is truly unique. Its known as a material that is sprayed as a liquid so that it can expand as a foam. It can create a solid layer across an existing roof. The foam itself is created by coupling two liquids, which are known as a polyol/resin and an isocyanate. It is applied by being sprayed onto the existing roof substrate. Because the foam expertly adheres to many surfaces, it can be installed on any roof slope. This is an admirable quality.

    Excessive Loss Of Granules

    Granules are the tiny little stones on the surface of shingles that protect the asphalt underneath from damaging UV rays. Once enough of these granules are lost from the shingle, the asphalt will dry out and lose its ability to remain watertight. You might also notice a lot of these granules built up in your gutters.
