Armstrong Foam Roofing has been upgrading and protecting homes since 1966. For over 40 years, we’ve specialized in spray foam roofing (also known as SPF roofing) for flat and low-sloped roofs, making us a true industry veteran in the San Francisco Bay Area. Our extensive experience in spray foam roofing, dating back to the early 1980s, has earned us the title of the company with the most residential foam roof installations in America. This depth of experience translates to an unparalleled understanding of the nuances of spray foam roofing, particularly in addressing the unique challenges presented by flat and low-sloped roofs in the San Francisco Bay Area.
Unmatched Quality and Durability
Armstrong only uses the highest quality 3LB foam, ensuring superior insulation values, strength, and longevity for your roof. This dedication to quality is reflected in the thickness of our foam roofing systems, which range from 1” to 3”. This commitment to high-quality materials and workmanship ensures a roof that is built to last and withstand the Bay Area’s diverse climatic conditions.
Ideal Applications
- Residential: Perfect for homes with flat or low-sloped roofs, especially Eichler homes and other architectural styles that benefit from a lightweight, durable roofing solution.
- Commercial Buildings: Effective for warehouses, retail spaces, and multi-story buildings, providing a robust roofing option.

When considering roofing options, it’s essential to choose a system that fits your specific building type and location. Spray foam is adaptable and can meet a wide range of needs.
Focus on SPF Roofing Technology
Unlike many competitors who offer various roofing options, Armstrong has chosen to focus exclusively on SPF roofing technology. This laser focus allows us to hone our skills and expertise in this specific area, resulting in a higher level of proficiency and specialization. This concentrated approach distinguishes us as a true expert in foam roofing, offering a unique depth of knowledge that surpasses general roofing contractors.
A Proven and Thorough Installation Process for Longevity
Armstrong’s installation process is designed to ensure the longevity of your foam roof. We start with a pre-site inspection conducted by an Armstrong Installation Department Technician. The homeowner is responsible for reimbursing Armstrong for the permit fee, and priming will be done as necessary to conform with city codes. In some cases, a Class-A substrate may be required by law, and stacks and vents may need to be replaced due to the condition of existing materials.

The next step is the application of a UV coating to protect the newly sprayed foam roof from UV radiation. Armstrong offers white, light grey, or tan coatings and granules. Armstrong has perfected the foam roofing process over our 4 decades of experience.
Customer Satisfaction is Our Priority
Since 1966, Armstrong has prioritized customer satisfaction. We take the time to understand your needs and provide personalized solutions, earning us a stellar reputation in the San Francisco Bay Area. Our commitment to customer satisfaction is further reinforced by the exceptional warranties we offer. With 15-year warranties on our foam roofs, we stand behind the quality and longevity of our work. This reflects our confidence in the durability and performance of our foam roofing systems.
Benefits That Set Us Apart From Conventional Roofing Contractors
Armstrong Foam Roofing offers a unique combination of benefits that set us apart from conventional roofing contractors:
- Superior Insulation: Foam roofing provides exceptional insulation, helping to maintain comfortable indoor temperatures and reduce heating and cooling costs. Homeowners who replace their built-up roofing (BUR) systems with foam roofing often reduce their heating and cooling costs by up to 40%.
- Unparalleled Waterproofing: The seamless application of spray foam creates a waterproof barrier that prevents leaks and water damage. Armstrong foam roofs are seamless, monolithic, and fully adhered. They are moisture-resistant even if the membrane coating is damaged. As a result, you can rest assured that your home or business is well-protected from the elements.
- Enhanced Durability: Foam roofing is highly durable and can withstand extreme weather conditions, including strong winds and heavy rain. Studies have shown that the physical properties of foam roofing do not diminish over time. Armstrong foam roofs are tough and tenacious. They can be sprayed onto almost any surface, including irregularly shaped roofs and uneven surfaces. This means fewer repairs and replacements, ensuring a long-lasting and reliable roof over your head.
- Low Maintenance: Foam roofs require minimal maintenance compared to traditional roofing options. You only need to recoat your foam roof approximately every 20 years to ensure it keeps performing like new. This saves you time and money in the long run, as you won’t have to worry about frequent repairs or upkeep.
- Minimized Mold Growth: The seamless and watertight barrier created by foam roofing prevents moisture from getting trapped, significantly reducing the risk of mold growth. This contributes to a healthier and safer indoor environment for you and your family.
Understanding The Armstrong Difference
As an established and responsible roofing contractor, Armstrong’s commitment to providing a top-quality foam roofing experience includes using closed-cell foam for maximum energy efficiency and durability. This type of foam is designed to provide superior insulation and protection from the elements. The tightly packed cells prevent air and moisture from penetrating, making it more rigid and stable than open-cell foam. This ensures a strong and weather-resistant roof that can withstand the test of time.

Energy Efficiency and Sustainability
Foam roofing is one of the most energy-efficient roofing materials available. It is over 500% more efficient than conventional roofs and, as we have already mentioned, can reduce heating and cooling costs by up to 40%. Research has shown that the energy savings from foam roofing can pay for its cost within 3 to 4 years.
Spray Polyurethane Foam (SPF) combines insulation and roofing into one material. Because it is lightweight, a complete tear-off of the existing BUR can be avoided when installing an Armstrong foam roof. This is better for the environment because all that material doesn’t end up in the landfill.
