Replace Your Flat Tar-and-Gravel Roof With Armstrong’s Spray Foam Roofing

Replace Your Flat Tar-and-Gravel Roof With Armstrong’s Spray Foam Roofing

Many homes and businesses in the San Francisco Bay Area, including Fremont, Oakland, San Rafael, Alameda, Palo Alto, Berkeley, Daly City, Burlingame, San Jose, El Cerrito, Concord, Walnut Creek, and Danville, have flat tar – and – gravel roofs. This type of roofing system has been around for decades and is offered by numerous roofing contractors at varying prices. Unfortunately, built-up roofing systems (BUR) like tar-and-gravel don’t really offer you much insulation value which means you need to spend money to insulate your roof. It’s also true that BUR roofing systems don’t offer great protection against leaks and moisture issues. That’s why for over 40 years Armstrong Foam Roofing has been offering residents of the San Francisco Bay Area a superior form of roofing that combines insulation and moisture resistance into one material. Spray Foam Roofing, is also a lightweight roofing system with incredible adhesive properties that can often be applied over existing, single layers roofs. As a result, this translates into faster installation time and lower installation costs.

What is Spray Foam Roofing?

Foam roofing is created using spray polyurethane foam (SPF). It is sprayed as a liquid onto the roof surface by mixing two highly reactive chemical compounds called isocyanate and polyol. The chemicals are pumped from separate containers through heated, high-pressure hoses to an internal mixing spray gun. Once this mixture is sprayed onto the surface of your roof, in three seconds, it rises to 1.5 inches. The foam hardens within a minute and can then be walked on. After hardening, the foam forms a monolithic cellular membrane covering the entire roofing system.

Once the polyurethane foam is applied and hardened, two layers of acrylic elastomeric coating are applied to ensure complete protection against UV degradation. Finally, before the last layer of elastomeric coating dries, a layer of durable ceramic granules is infused into it to create a super-strong seamless impenetrable waterproof roofing system. If properly maintained Armstrong’s foam roofing systems can last a lifetime by only having to recoat them approximately every 20 years. Naturally, with Armstrong’s 15-year warranty coverage, your property will be weather protected which can also increase your property value.

The Main Benefits of Replacing Your Tar-and-Gravel Roof with Foam Roofing

No More Moisture Issues or Leaky Roofs

If you have a tar-and-gravel roof, you probably notice some degree of ponding after a rainstorm. This could be an issue especially if the water builds up and stagnates on the surface of a roof for longer than 48 hours. Armstrong’s SPF seamless foam roofing membrane can easily and effectively fill voids, holes, and low areas to enhance drainage and increase stability. What’s more, it makes it possible to seal effectively around difficult roof features such as skylight windows or circular exhaust vents. As a result, it provides excellent water resistance. After Armstrong installs your foam roofing system, you won’t have to worry about moisture issues or a leaky roof.

Cut Heating and Cooling Costs

Another significant benefit of replacing your tar-and-gravel roof with foam roofing is the increase in thermal resistance or R-value. When you have foam roofing, you do not have to worry about additional insulation in your ceiling. In fact, foam roofing can be up to 500% more efficient than conventional tar-and-gravel roofs. Inch-per-inch, foam roofing has tremendous insulation value and maintains this value for decades.  San Francisco Bay Area homeowners who replace their BUR roofs with foam roofing often reduce their heating and cooling costs by up to 40%. 

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.

Why Choose Armstrong Foam Roofing to Replace Your Tar-and-Gravel Roof

Today, there are many foam roofing contractors in the San Francisco Bay Area to choose from, however, you must keep in mind that your foam roofing system will only be as good as the individuals who apply it. Consequently, you should contact professional local contractors with years of proven expertise and a high degree of technical knowledge. 

Your foam roofing system is durable but it must be installed under ideal weather conditions and on well-prepared surfaces to ensure the material adheres to your roof properly. It’s also important that your new foam roof is applied evenly to avoid small areas where rainwater may form puddles since this can eventually damage your roofing material.
