Coating an Existing Roof in Clark County WA

What Is a Spray Foam Roofing System?

Spray polyurethane foam (SPF) roofing enhances the strength and weather resistance of your commercial building. Spray foam insulation forms an airtight layer that prevents heat loss in winter, keeps buildings cooler in summer and strengthens roofs. We can apply spray foam insulation over an existing roof, to both interiors and exteriors.

What Is a Spray Foam Roofing System?

Spray-On Foam uses a zero-ozone-depleting spray polyurethane foam designed for roofing. Once in place, the insulation expands to fill cracks and crevices before hardening into a rigid layer. The insulation forms a seamless layer.

Our technicians begin by preparing the surface of the roof. They then spray the foam to a prescribed thickness. A finishing coat is the last step. The coating enhances the weather-resistance and durability of the surface.

This type of insulation uses a closed-cell formulation that resists water. The coating adds protection from ultraviolet light. The coating may also add other properties such as improved appearance, protection from moisture, resistance to abrasion, and fire resistance.

What Is the Life Expectancy of an SPF Roof?

SPF roofing systems are low maintenance and long-lasting. An SPF roofing system can last for 30 years or longer. The durability of SPF depends on the quality of the application. To ensure your roof lasts, you’ll need to choose a company with a good track record of service. Spray-On Foam has been working in Vancouver, Washington, Portland, Oregon, and the surrounding areas since 1973.

What Type of Roofs Can Use SPF?

We apply SPF on many types of buildings and surfaces. Because SPF is lightweight, it can be used to recover an existing roof. We can spray on metal, concrete, wood, and built-up roofing (BUR). Before we apply SPF roofing, we’ll make a thorough inspection to ensure it’s the right choice for your building.

Does SPF Roofing Need Maintenance?

You should inspect your roof about twice a year and after weather that may have caused damage. You can fix some small punctures or scratches with a sealant. Repair extensive destruction by replacing the damaged areas with a new application of foam and coating.

Re-apply coating for SPF roofing systems about every 15 years or as needed. The minimal maintenance of SPF makes these roofing systems ideal for companies seeking to reduce costs associated with building upkeep.
