The Insulation and Strengthening Properties of Armstrong’s SPF Roofing

For over four decades, Armstrong Roofing has been installing Spray polyurethane foam (SPF) roofing systems on flat and low-sloped roofs in the San Francisco Bay Area. In fact, during this period, Armstrong has installed more residential foam roofing than any other company in America! 

Insulation Properties of SPF Roofing

One of the many benefits of foam roofing is its incredible insulation properties. That is why SPF roofing systems are a perfect solution for flat and low-sloped roofs which require a very light and seamless material to provide them with the maximum protection against the elements. To control heat, air, and moisture, it is necessary to have effective air barriers, rain screens, weather barriers, and thermal insulation that is seamless to avoid gaps that can compromise the designed climate control. This can be achieved effectively with SPF roofing because it is applied as a liquid which expands and spreads into all the seams and cracks of the substrate or surface area it has to cover. Essentially, the foam wraps around roof structures eliminating the possibility of air infiltration and sealing the building airtight. 

Currently, there is not really any other insulating material that can provide your home’s flat roof with an airtight seal which can enable you to maintain a constant, comfortable temperature both in summer and winter. This is also due to its R-value (insulation capabilities) which is very high compared with other forms of insulation. What’s more, the fact that it has no fastener increases energy efficiency since fasteners have been reported to reduce the insulation value from 1.5% to 31.5%. In addition, the reflective nature of the light-colored coating applied over the foam also reduces the effects of the sun on your roofing system (keeping it 50 to 80 degrees cooler) which significantly decreases cooling costs during the summer months.

Strengthening Properties of SPF Roofing

Unlike traditional built-up roofing (BUR) systems, SPF roofing also adheres to almost any roofing surface/material so you can be sure it will not sag, shred or come off, even under hurricane conditions. In fact, it adds structural strength to the building envelope, because the foam forms a chemical as well as a mechanical bond with building surfaces.

It’s also important to consider that SPF is highly durable and its physical properties change little with time. It is estimated that with proper installation and maintenance, your SPF roofing system can protect your home for a lifetime. You only have to recoat it every 20 years to ensure it keeps performing like new. 

Another important benefit of Armstrong’s SPF roofing systems is that they can provide added strength to the roof. For example, SPF has a compressive strength of 40 to more than 60 pounds per inch and its adhesion strengthening capabilities are significant, especially in areas with severe weather conditions that can damage your roofing structure.
