Are foam roofs any good?
Like any kind of roofing system, foam roofing has its pros and cons. Overall, however, the pros often outweigh the cons when it comes to this lightweight material. It’s especially valuable for commercial flat roofs, but can be applied to homes with flat roofs as well. Foam is directly applied over the original roofing material, creating a seamless membrane over it. This membrane is highly water resistant, so leaks become less of a worry, and serves as thermal insulation, so the roof’s energy efficiency improves. This material is dense, so you may not even need attic insulation.
Moreover, foam is durable. Can you walk on a foam roof? Yes, it handles foot traffic well. It will also last a long time if well maintained. On the downside, foam by itself deteriorates in the sunlight and can be dented easily, so it requires a coating like silicone or acrylic applied over it for added protection. The chief maintenance requirement, then, is that the coating needs to be reapplied every 10 to 15 years. With such maintenance, the foam roof could last as long as 50 years.

What is a foam roofing system?
Foam roofing and coating are often used as an alternative to roof replacement. These two materials combined form a complete roofing system that fits over your old roof. The foam, commonly called SPF spray foam, is a combination of isocyanate and resin. When these materials mix in the spray nozzle they react chemically, and as they are sprayed over the roof they expand and form a lightweight solid membrane over the roof. To keep the foam from decomposing in the sun, an elastomeric coating like acrylic or silicone is applied over it. This coating not only protects the foam, but it also provides additional protection to the roof and additional insulation.
Is spray foam worth the cost?
Foam roofing is often applied to commercial roofs as an alternative to roof replacement. When compared to the cost of a full roof replacement, you’ll be saving quite a bit of money with spray foam. You don’t have to, for instance, remove your old roof. Foam is directly applied to it after it is cleaned and minor repairs are made. Because spray foam improves your roof’s insulating abilities, you’ll also discover cost savings on your energy bills, which is always a plus. The main downside as far as maintenance costs go is that it requires a reapplication of roof coating to preserve the foam from deterioration and damage. Of course, this expense is only required every 10 to 15 years or so.
Can spray foam rot your roof?
You may have heard that spray foam can rot your roof. This is primarily a concern for spray foam applied as insulation on the underside of roofs. It’s generally not a concern of foam roofing applied over an old roof. Still, since the materials used for these applications are similar, there may be concerns about both in regards to rotting. The concerns are generally unfounded. Spray foam, inside or out, will not cause your roof to rot. Moisture is always the culprit when it comes to rot. The open-cell spray foam that is used as insulation actually can help prevent water from getting caught between your roof and the insulation. The foam allows moisture to pass through it, keeping it from collecting. If the water collects between your roof and insulation, this is where you can potentially have problems with rotting.

Foam roofing for commercial building
Foam roofing is primarily used on commercial roofing. It’s a very versatile material. It’s ideal for flat roofs as well as metal, as it adheres to most surfaces. At the same time, it can be used on residential roofing, though it’s not recommended for shingle roofs.
