Also referred to as Spray Polyurethane Foam (SPF), foam roofing is a relatively new type of roof. Owing to its numerous advantages (more on that later), the roof is used in various modern commercial and residential structures.
As the name suggests, SPF roofs are made up of polyurethane foam and elastomer coating. It is applied in a unique way, which sets it apart from its competitors. The application of SPF roofing entails the use of a liquid onto the existing roof. This helps fill all the gaps, cracks, and seams in the already-installed roof. Let’s look at some more pros as well as cons of foam roofing.
Pros of Foam Roofing
1. Easy to Install
One of the best things about foam roofing is that it boasts a smooth and flexible installation. Owing to its straightforward application, SPF roofing can be applied to any type of roof – wood, metal, concrete, and so on. Foam roofing can also be applied to roofs with an irregular shape. This helps strengthen and intensify the quality of your existing roof.
2. Water- and Weather-Proof
Another great advantage of foam roofing is that it has great water- and weather-proofing properties. Polyurethane foam is known to be the best insulator that perfectly absorbs heat and prevents water from ruining the roof. Whether you live in an area that receives the highest annual rainfall or faces the worst form of summer, foam roofing will prove to be ideal for you.
3. Keep a Structure Intact
Foam roofing helps maintain structural integrity for years. Houses and buildings with SPF roofs remain strong and sturdy against harsh weather conditions – strong winds, extreme sunlight, heavy rainfalls, etc. The best part? SPF roofs are fire-resistant, too!
Cons of Foam Roofing
1. Limited Application Window
Owing to its unique installation method, foam roofing can be applied only in specific weather conditions. For instance, the roofing is hard or impossible to be performed during heavy rainfall, frosting, windstorm, etc.
2. High Maintenance
SPF roofing requires a twice-a-year inspection. Look for damages or wear and tear after a bad weather condition. Even in case of small cracks or punctures, you will need to immediately hire a professional repair or maintenance contractor.
3. Requires Special Repairs
In case of any damage or collapse, SPF roofing can’t be handled like any other roof system. It needs specialized attention from contractors that are specifically trained to deal with this specific type of roofing. Because of this, the repair costs can be expensive.
