Four Ways Spray Polyurethane Foam Can Enhance The Performance Of A Flat Metal Roof

Metal roofs are durable structures that can last for decades without experiencing structural issues. On its own, metal reflects solar radiation, keeping the indoor spaces cool in the summer. If you have a flat metal roof, you can further enhance its performance by installing spray polyurethane foam (SPF). Spray foam is an insulation product that is sprayed on the surface of roofs to boost performance. Below are four ways it can improve the functionality of your flat metal roof.

Makes the Roof Waterproof

One of the greatest drawbacks of flat roofs is poor water shedding. The lack of an elaborate slope causes water to pool on the roof's surface, increasing the risk of leaks, especially if the material is worn. Spray polyurethane foam can protect your metal roof from leaks. The type of foam used on roofing surfaces is closed-cell foam. Closed-cell foam is moisture impermeable, meaning water cannot move through it. Once you apply it to your metal roof, it fills the entire surface, including the nooks and crannies. It creates a waterproof barrier that protects the metal roof from leaks.

Boosts Energy Efficiency

Although metal reflects UV radiation, an uninsulated metal roof can still absorb solar heat in the summer. Insulating your roof's surface is an excellent way of boosting the structure's energy efficiency. Spray foam has exceptional thermal resistance properties. Thus, it can prevent most of the solar heat from penetrating the roof. These superior insulation properties of foam allow you to enjoy indoor comfort without overworking your air conditioner during the summer. 

Improves Roof Drainage

As aforementioned, flat roofs experience poor drainage due to their design. Water takes longer to drain from the roof, which can compromise the structure's integrity. Foam can boost the drainage capabilities of your residential roof. During installation, the insulation is sprayed in layers. Your contractor can apply more product to the lower areas of the roof to create a slight slope. This allows water to shed smoothly from the structure and the guttering system.

Enhances Roof Performance

Metal roofs are incredibly durable and reliable. However, inclement weather and improper maintenance can shorten the lifespan of the roof and necessitate costly repairs. You can enhance the roof's performance and lifespan by installing spray foam insulation. Once the insulation is sprayed on the metal surface, it creates a layer of protection against inclement weather, impact, and solar radiation. Consequently, the roof will last longer and perform better than it would have without the insulation.

Spray foam is an excellent insulation material for flat metal roofs. For further information regarding foam roofing system installation services, consult your roofing contractor.

Roofers Keep You Safe

If you were asked to list professions that focus on safety, which ones would come to mind first? Most people would name police officers, firefighters, and perhaps forest rangers. But what about roofers? They may not seem like the most likely of answers, but think about it. Roofers put roofs on your home, and roofs definitely keep you safe. Your roof protects you from storms. It protects you from tree branches. It even protects you from the scorching hot rays of the summer sun! So, there you have it — roofers keep you safe! We are excited to write more about roofers on this blog.
