Does your flat or low-sloped roof have drainage problems and water seepage? Is it poorly insulated? Let Armstrong Foam Roofing show you how replacing your built-up roofing system with our foam roofing can protect your property while saving you money! 

Foam roofing consists of a monolithic layer of solid closed-cell polyurethane foam that is created by mixing two liquid chemicals together which react to form a solid piece that easily adheres to the roof. The foam density used by Armstrong Foam Roofing is rated at 3LB which means that our roofs have the highest quality roofing foams available today. The 3LB foam used offers high insulation values, strength, and exceptional longevity.

Armstrong Foam Roofing has been proudly providing foam roofing solutions for flat and low-sloped roofs for more than 40 years.  It is one of the most popular ways to make your roof cool and energy efficient. Foam roofing is recommended by the Energy Department as it is a long-lasting ultra-light insulating foam that will keep your home cool during summer and prevent the heat from escaping in winter. Most importantly, we understand that replacing your roof is not easy and it can be costly. That’s why we provide San Francisco Bay Area residents with foam roofing systems that can last a lifetime by only having to recoat them approximately every 20 years.

Why Choose Foam Roofing?

Spray foam roofing is the ideal solution for your flat and low-sloped roof problems. It is the first intelligent roofing technology that combines insulation and roofing into one material. What’s more, each Armstrong foam roof is custom installed and backed by some of the best foam roofing warranties in the industry. 

1. Offers Effective Insulation

Foam roofing is the most energy-efficient material available – over 500% more efficient than conventional roofs. Research by Texas A&M University has shown that the energy savings from foam roofing can pay for its cost within 3 to 4 years. Also, the fact that it has no fastener increase energy efficiency since fasteners have been reported to reduce the insulation value from 1.5% to 31.5%. Plus, the reflective nature of the light-colored coating can help keep your roof to 50 to 80 degrees cooler, significantly decreasing utility costs during the summer months. 

2. Seamless and Moisture-Resistant

Spray foam roofing has no seams or multiple layers – eliminating the expanding and contracting and separating that allows water and microbes to seep in and damage your roof. It also eliminates roof leaks caused by faulty flashing because SPF conforms to any substrate when installed. This makes it ideal for flashing parapet walls, equipment, skylights, and cooling towers.

3. Incredibly Durable

Foam roofing provides superior hail and impact absorption – even if a wind-driven missile damages the roof, it will rarely cause a leak and the damage can be easily repaired without compromising performance. Foam roofing also provides high wind uplift resistance, proven by field observations of foam roofing performance during Hurricanes. Another important feature of SPF roofing systems is the fact that they have no fasteners which can come loose or damaged.

4. Sustainable and Eco-Friendly

With proper installation and maintenance, your foam roofing system can protect your home for a lifetime. You only have to recoat it approximately every 20 years to ensure it keeps performing like new. Consequently, foam roofing eliminates the need for costly roof tear-offs and waste which will end up in landfills. Because the foam can adhere easily to most materials, in most cases, the installation of foam roofing requires minimal stripping of the original roof (saving you time and money as well).

5. Extremely Lightweight

Foam roofing systems weigh approximately 60 lbs per 100 square feet versus 600 lbs per 100 square feet for a typical built-up roofing system (i.e. tar and gravel). As a result, it can be applied directly to many existing roofing systems without adding significant stress to the walls and beams of a building making it ideal for older homes like the Eichlers.

The Benefits of Foam Roofing

Each Armstrong Foam roof is custom installed. It’s sprayed on as a liquid mixture, and within a few seconds expands up to 30 times its original volume into a watertight, seamless solid that custom forms to the roofing substrate. Just look at the advantages of an Armstrong Foam roof:

  1.  Tough, seamless construction
  2.  Can be sprayed onto almost any surface including irregularly shaped roofs and uneven surfaces
  3.  Tenacious adhesion – demonstrated in the most recent Florida hurricanes
  4.  Moisture resistant – even when the membrane coating is damaged
  5.  Inch-per-inch, the highest energy-efficient roofing material available
  6.  Extremely strong – yet ultra-lightweight
  7.  Proven longevity classifies it as a sustainable low-slope roofing system
  8.  In most cases requires only periodic recoating for decades of service
