Learn More About Foam Roofing
Your commercial or industrial roof deserves to have durable and protective materials that will last for years to come! With foam roofing, you can expect a firm roofing material that is easy to install and can protect your roof from the influences of everyday wear and tear as well as weather. When you’re wondering is foam roofing good for your commercial roofing than it’s best to get to know the system more before commitment. There are foam roofing pros and cons just like with anything and contacting a professional roofer can give you an idea of what will work with your particular roof’s substrate. In the meantime, here is some helpful information that can give you an idea of why foam roofing can be right for your property!
What is spray foam roofing?
Foam roofing is a type of roofing application that is typically sprayed as a liquid and will then expand into a foam which will then cure to the materials of an existing roof and thereby create a solid new layer.
How to Apply Foam Roofing
Foam roofing will need to first have an existing roof underneath it before it can be sprayed on. The existing roof or substrate should be prepared by cleaning it by getting rid of dust, dirt, and other debris. This can be done by vacuuming, air pressure or even sweeping the roof with a broom. As long as it’s clear of contaminants the first layer can be applied by a professional roofer. The liquid spray will expand to foam about 20 times in size of its original state to form to about 1 to 1.5 inches in thickness. It will cure and adhere to the surface of the roof as a solid and seamless surface. Once foam roofing has been completed, generally a layer of acrylic or elastomeric roof coating with embedded granules will be applied on top. This will protect the roof from weather, UV light, temperature changes, fire, and normal wear. The layer is typically 20-30 mils in thickness and will create a durable, moisture-resistant and seamless roof cover.
How long do foam roofs last?
Foam roofing has a high roof life and can last over 50 years! To reach this roof life it will require periodic maintenance in order to see if any recoats are needed. In general, it may need to be cleaned, primed and recoated every 10-15 years.
Can you walk on a foam roof?
Foam roofing, unlike what’s usually believed, can be walked on and is even able to support a lot of weight. As can be said of any type of roofing material, the catch is with extremely sharp objects which can compromise the system by leaving a hole in it.
Foam Roofing Pros and Cons
- Easy Installations
- Energy Efficient

- Lowers Emissivity
- Minimal Upkeep
- Can Stop Leaks
- Can Be Applied to Various Substrates
- 50+ Year Life

- High Costs
Is spray foam watertight?
Foam roofing can be watertight depending on the density of the foam that is used. If you’re interested in watertight foam roofing aim for an option that has both high-density and closed cell as they are water-resistant as opposed to open cell which is not.
Will spray foam stop water leaks?
Foam roofing does have the ability to provide some restorative functions as well since it will expand into and fill up punctures and cracks where potential openings for water can leak through. An expanding foam like polyurethane will bond to any surface and effectively stop leaks.
Spray Foam Roofing Benefits
Foam roofing has a variety of benefits that can enhance your roofing material. Firstly, installation is easy as the application of foam roofing involves simply having an even spray. What’s more, the application process won’t interrupt the routines of business, industries, and other buildings as it’s fast. The application is a liquid spray which will expand and conform to any roof shape and type. It’s versatile and can be applied to irregular shaped roofs, shingles, metal, asphalt, concrete and wood. Another benefit to foam roofing is that it’s energy-efficient. It will provide air, thermal and moisture barries to a roof’s insulation and even has the highest R-value per inch. With polyurethane coatings, it’ll keep heat in during the winter and out during the summer which assists the HVAC in maintaining stable temperatures. With silicone top coatings you can even reflect UV light which lowers emissivity/heat absorption which will ultimately cool a building’s temperatures. Not only will this provide protection from the damaging effects of the sun, but it’ll also conserve energy and therefore lower monthly energy costs! Finally, once it has been applied you can expect as minimal maintenance as blind repairs with semi-annual inspections in the Spring and Fall if possible. As of such, foam roofing can be expected to last over 50 years with these simple check-ups in order to apply a recoat if needed.
