A foam roof is something many property owners have not heard about. This roof consists of layers of spray foam over a substrate and covered by several layers of protective coating. The protective coating protects the foam from UV rays and provides a sturdy surface to walk on for routine maintenance. This system is quite durable when properly installed.
In some form or another, the foam roofing system has been around since the 1980s. Not only does the foam help keep the wind and rain out, it provides extra insulation down below.
What Can Cause Leaks in a Foam Roof
Leaks in a foam roof can come from many causes:
- Wind-driven debris – Small sticks and other pointed debris can penetrate the upper layers of the roof allowing moisture and wind to get in.
- Dropped tools – If you or a tradesman drop a tool on the roof surface, it can penetrate that critical protective layer.
- Walking on roof – The protective layers are okay for walking on. However, hard shoes can cause dents and dings in the roof where water can pool and eventually penetrate.
- Surface damage to protective layer – Any damage to the protective layer allows sun, wind, and water to get into the foam layer.
- Exposure to UV rays – An inadequate protective layer allows the sun to reach the foam layer which deteriorates due to UV ray exposure.
- Hail – Hail can leave a series of deep dings and dents in the protective layer. These can penetrate to the foam layers below.
How Much Damage Is There?
Before learning how to repair a foam roof, you need to know how much damage is done. If there is a great deal of damage, you will need to call in a foam roofing expert to make major repairs or do a whole roof replacement.
Where is the leak?
If you have an attic space, look for where the water is coming in from underneath. If you do not have an attic space, then go up on the roof. Remember to wear soft shoes. Look in the area where you have water coming in. You will likely find the roof’s protective layer breached. Once the protective layer gets a hole in it, water, wind, and sun will begin to do their damage. Another thing to look for is water penetration around chimneys, vents, and skylights.
Look at the damaged area. If it is a small dent or crack, you can make the repair. However, if the area of damage is large, you need to bring in a professional roofer to make the repairs. A foam roof offers long-term solid protection for your building. Getting professional repairs will keep that roof going a lot longer.
