Armstrong Foam Roofing San Francisco Bay Area

Armstrong installed a white spray-foam roof on my house in August 2025. I'm very happy with the roof and highly recommend this company. Before choosing spray foam, I consulted several roofers and explored the options (single-ply, modified bitumen, etc.) and decided spray foam had the best combination of pros and cons, including cost. I was under an insurance company deadline to replace the roof. Wayne at Armstrong was understanding about the deadline and assured me they would meet it. Even though Armstrong does a high volume of roof projects, Wayne and the project foreman, Eliseo, found ways to fast-track the job, and they finished a few weeks before the deadline. The project was complicated because of certain issues with the roof. Wayne was great at communicating with us and providing guidance as our carpenter dealt with the various challenges. He always replied quickly when I contacted him, and he came by a few times during the prep work we did to check our progress and provide advice. Wayne has decades of experience and extensive technical knowledge. He was easy to work with and very flexible in syncing his schedule with ours. He was fair and generous in dealing with some unexpected problems. Because of ground settling, one corner of the roof is a bit lower and heavy rain would cause a waterfall there. I'd asked several roofers how to fix this and no solution seemed completely right. Wayne and Eliseo recommended raising the fascia, adding a new drain at the problem corner, and sloping the foam from the fascia to the drains. The problem was that a new downspout at that corner would look terrible architecturally. Eliseo thought of a brilliant solution: run the downspout along the siding and tie it to an existing downspout. He did that, the new downspout looks great (minimally visible), and I'm thrilled their solution fixed the waterfall problem, even during torrential rains. Wayne also provided great advice on various other aspects of project and his team took pains to do a good job, all of which helped with functionality and made the new roof look well-designed and professional. I noticed that some of the products Armstrong uses, like the bonderized steel fascia, are higher quality than what other roofers proposed to use. Note to anyone intending to tear off a tar-and-gravel roof: in our experience the tear-off of the old tar-and-gravel roof was challenging. It was done by another company that Armstrong works with. Removing this type of roof is a very messy process. A blizzard of tar and gravel debris and dust went everywhere. The workers put some plastic on the ground around the house, which helped a tiny bit, but with the wind blowing and the gaps between the plastic sheets, the debris went everywhere. Also, Wayne's assurance that the insulation layer on the old roof would keep debris from getting inside the house didn't turn out to be true because of the way the roof was removed. When the tear-off was done, the grooves between the roof boards were packed with tar and gravel debris. The workers wanted to blow the debris off into the yard. We didn't want all that debris in the yard and had to spend a week vacuuming the roof so it wouldn't work its way between the roof boards into the house. Despite all the vacuuming, a lot of debris did fall inside. The tear-off company had tacked up plastic under the ceiling to catch it and they kept saying the plastic would work. In reality, although it caught most of the debris, plenty of debris did fall into the house. Cleaning up, inside and outside, took us a couple weeks. Maybe there's a better way to tear off a tar-and-gravel roof. Regardless, the new roof is fantastic. Temperature insulation is clearly improved. On hot days, the house no longer heats up like an oven. Heating bills seem to be roughly 15-20% lower. Installing a spray foam roof that performs well requires significant expertise and experience and a top-quality foam product. Armstrong is one of the largest, oldest spray foam companies in the Bay Area, and they stand behind their work with a long warranty.

I recently had Armstrong Roofing handle a roofing project at my home, and I couldn’t be happier with the entire experience. Eli was the representative who came out for the inspection and estimate, and he immediately stood out with his professionalism and clear communication. He took the time to explain the condition of the roof, walked me through the options, and provided a fair, straightforward quote that made sense. Once we moved forward, the crew arrived on schedule and worked efficiently from start to finish. The workmanship was excellent, everything was done exactly the way Eli explained it would be. The team kept the area clean throughout the project, and the final cleanup was spotless, which I really appreciated. The whole process felt organized, honest, and well managed. Eli checked in during and after the job to make sure everything was completed properly and that I was satisfied. Overall, Armstrong Roofing delivered top quality work, and Eli made the entire experience smooth and stress-free. I’m extremely pleased with the results and would highly recommend them to anyone considering a roofing project.

We hired Armstrong Co to update our roof with foam material in 2019, and unfortunately, we are now dealing with serious issues due to their poor installation. Our home insurance provider has refused to renew our policy because of pooling water on the roof, which has led to excessive moss growth and leaks inside our home. When we contacted Armstrong about the issue, they claimed it was not covered under their warranty and told us to hire someone to pressure wash the roof—saying this was “normal.” This past weekend, we personally removed 10 pounds of moss from the roof, which should not be necessary on a properly installed system. A well-installed roof should not have pooling water, nor should it require frequent pressure washing to function properly. We are extremely disappointed with Armstrong’s lack of accountability and would not recommend them to anyone looking for a reliable roofing company.

I recently worked with Wayne from Armstrong Roofing after realizing we needed to replace the roof on both our main home and ADU unit. From the very first meeting, Wayne was knowledgeable, professional, and patient in walking us through all of our options. He explained the benefits of the foam roofing system, how the removal and installation process would go, and what to expect every step of the way. His communication was excellent and made the entire experience stress-free. The crew arrived right on schedule, worked efficiently, and kept the property clean throughout the project. The final result looks fantastic, you can immediately tell it was done with care and precision. The pricing was very fair considering the quality of materials and workmanship, and the project went exactly as Wayne described. I couldn’t be happier with our experience and would highly recommend Armstrong Roofing to anyone looking for a dependable, professional roofing company that truly stands behind their work.

They did a sloppy job on my roof. Lots of dips, thus lots of water pooling. They used gravel to fill in the dips which gathered dirt and mold. Not a good situation. The roof started leaking after only 7 years. Hopefully you will have a better experience.
