Spray foam roofs are commonly used in many buildings throughout the country. Because of the conditions in which they must be installed, they’re especially popular in the Phoenix-Mesa area, too. Spray foam roofs are also great for low-pitched or flat roofs, they’re durable, and they’re extremely energy efficient.
Of course, spray foam roofs are not without their issues. The good thing is that knowing what kinds of problems may arise can prepare you to have a solution ready to go. If you do have a foam roof and want to learn more about common spray foam roofing problems and how to fix them, keep reading.
What is A Spray Foam Roof?
Also known as Spray Polyurethane Foam (SPF) Roofing, spray foam roofing is a type of material that sprays liquid and expands as it turns into foam, creating a layer across the roof. This method is generally used to repair an existing roof by fixing it up and spraying foam over the top of it to create a new, smooth roof. SPF roofing is generally used for residential and commercial buildings that have flat roofs.
Common Spray Foam Roofing Problems
Since foam roofing is sprayed on, there is a chance for “overspray”, which happens when droplets of material land onto other areas of the building or property. A professional roofer should know how to avoid this by using a windscreen, covering items that are fixed to the roof, and using plenty of other methods of protection.
While spray foam roofs are fairly durable, rough weather conditions can cause punctures in the top silicone layer of the roof that lead to leakages. Any severe problems can usually be avoided with regular inspection and, if necessary, repairs can be made to fix the problem.
Spray foam roofing is infamously known for its weakness against the sun’s powerful ultraviolet rays. Over time, harsh sunlight can cause SPF roofs to deteriorate quickly over time. Luckily, there is an easy solution for this. Roofs can cover an SPF roof with an elastomeric membrane made of silicone, acrylic, or urethane. These membranes provide UV protection as well as waterproofing and impact resistance to help protect against punctures.
Conditions for Installation
SPF roofs must be installed in very specific weather conditions. It must be warm (over 50 degrees Fahrenheit), dry, and there shouldn’t be a lot of wind (this prevents overspray). Finding a time when these conditions come together can make it difficult to install these roofs with ease. Luckily, living in Arizona, days like these occur fairly often.
How to Maintain a Spray Foam
Spray foam roofs require a decent amount of upkeep. Because harsh weather conditions can cause damage to an SPF roof, they need to be regularly inspected for damage throughout the year, especially after a harsh storm. Luckily, most roofers will offer a maintenance plan or warranty on your SPF roof, which means your inspections should be low-cost or free.
