Spray Foam Roofing For Commercial Applications And Its Benefits
Spray foam roofing for commercial buildings is a great option if you need a new roof. If you have a commercial building, the roof needs to be able to withstand heavy weight from snow, water, and strong winds from any direction. Spray foam roofing provides all of this and more. Here are some of the applications and benefits of installing a new spray foam roof for your business.
The Decking for Spray Foam Roofing
The decking for a spray-foam roof is engineered to minimize both weight and cost. Deck materials are usually made of wood but can also be metal, concrete, or composite. Composite decking is a relatively new option and has become popular because it surpasses other decking materials in strength, durability, cost, and appearance. One of the chief advantages of composite sheathing is that it requires little maintenance.
In addition, spray foam roofing also requires an impermeable moisture barrier. This is a layer of felt paper or synthetic moisture barriers that help to keep liquids in place while the roof is being sprayed on. This allows for the polyurethane mixture to properly cure and form the foam that makes the body of the roofing system.
Installation of Spray Foam Roofing
The installation method remains the same whether the foam is applied on a commercial property or a residential one. Commercial roofs, especially flat roofs, are expensive to replace. They require major roof repairs, which can be costly depending on the building's size.
Spray foam (SPF), or polyurethane, is a liquid applied as foam that expands up to 200 times its original volume. Once applied, the SPF forms a protective airtight seal.
SPF has gained popularity as a protective roof covering because it seals out water, thereby reducing the need for roof maintenance. Additionally, SPF is versatile, with the ability to be installed over a variety of existing roof types, including metal, asphalt, wood, tile, and more. While SPF is easy to install, it also requires regular care and maintenance. The finish layers of SPF roofs, however, are fairly simple.
The finish layers consist of a coating, usually elastomeric, and a topcoat. Spray polyurethane foam (SPF) requires three layers of coatings: a primer, basecoat, and topcoat.
- Primer—The primer layer is an important part of SPF roofing. It acts as a bonding agent between the SPF and the roof deck.
- Basecoat—The basecoat seals the primer layer and is the basecoat for the topcoat. The topcoat seals the basecoat and is the final coat of the SPF roof.
- Finish—The finish layers are applied after the roof decking is completely dry. The finish layers are acrylic or elastomeric coatings and are typically applied in several thin coats.
- Topcoat—The topcoat is the final coat of the SPF roof. It seals the finish layers and provides additional protection against wear and tear.
Spray foam roofing is also cost-effective. The foam is also lightweight and easy to apply. Spray foam roofing is environmentally friendly because it reduces the amount of energy needed to keep the building cool. It's made from non-toxic, inert material. It is also a recyclable roofing material.
Spray foam is a sound solution for commercial structural roofing when applied properly. For more information on foam roofing system installation, contact a roofing contractor.
