Spray polyurethane foam Roofing installation and repair
At USA Spray Me, we install spray polyurethane foam roofing systems for flat and low-slope roofs on residential homes, commercial buildings, warehouses, and industrial facilities across San Francisco and the Bay Area. SPF is applied as a liquid that expands into a rigid, seamless foam layer – creating an unbroken surface with no joints, seams, or penetrations where water can get through.
Spray foam roofing provides both insulation and waterproofing in a single application. The foam’s high R-value per inch reduces heat transfer through the roof, lowering HVAC load and energy costs year-round. Once applied, the foam is protected with a UV-resistant elastomeric coating that shields the system from sun, rain, foot traffic, and weathering.
SPF roofing can be applied directly over most existing roof types – including built-up roofing, modified bitumen, and metal – without requiring a full tear-off. This reduces demolition costs, installation time, and disruption to the property. Our foam roofing contractors assess every existing roof before installation to confirm compatibility and surface condition.
We also provide spray foam roof repair and recoating services for existing SPF systems. When the protective coating shows wear, a fresh topcoat restores the system and extends its service life by another 10 to 15 years – making foam roofing one of the most renewable and cost-effective commercial roofing options available.

We install spray foam roofing systems for homes and commercial buildings across San Francisco and the Bay Area, delivering seamless waterproofing, strong insulation performance, and dependable long-term protection.
Efficient, fast, great price. They left the place clean, they were helpful, respectful. I would recommend them to anyone needing spray insulation in their walls.
I am very happy with the work.
Great customer service. The work was done on time. I also got a great price.
Company work around my schedule and budget.
Andrei gave me great advice on foam insulation.
He took before and after pics.
I contracted with USA Spray Me, to blow insulation into my ceiling due to the impact noise above, and to do spray foam in my basement ceiling, due to the chilly wetness in my unit.
The salesman was informative and a pleasure to do business with. The crew showed up on the day and time that they said they would. They tented the inside of my unit, and my condo was clean and neat afterwards, which was a big relief. The work was well done and as contracted. …
They did insulation for our upstairs in our newly renovated home. We noticed that despite all of the work performed the insulation needed to be done to make our kids rooms warmer. I reached out and they were available the next day!! When I say these guys were professionals, they were professionals. They treated our home with the utmost respect and did an excellent job. My kids rooms feel a 1000% better! Their pricing is competitive and I absolutely 100% recommend them! I hate that I didn’t get around to posting this review earlier.
Hired USA Spray Me for sandblasting and recoating on a commercial property I manage. They handled the prep work thoroughly and the coating went on smooth and even. The crew was organized, communicated well throughout the project, and finished ahead of schedule. Would use them again without hesitation.
USA Spray Me is the best blown-in insulation company I’ve worked with. They helped me add extra insulation to my old house, and the whole process was quick and hassle-free. The team was friendly and explained everything before they started. My home stays warmer now and my energy bills dropped. Highly recommend!

Frequently Asked Questions About Spray Foam Roofing
Here are answers to common questions about spray polyurethane foam roofing installation, repair, and maintenance.
Spray polyurethane foam roofing is a two-component liquid system that is spray-applied directly to the roof surface. The two components react on contact, expanding into a rigid closed-cell foam that bonds to the substrate and cures within seconds. The result is a seamless, continuous insulation and waterproofing layer across the entire roof.
Once the foam is applied and cured, a UV-resistant elastomeric topcoat is applied over the surface to protect the foam from sun degradation, physical damage, and weathering. The complete system provides insulation, waterproofing, and weather protection in a single application.
Spray polyurethane foam is best suited for:
- Flat and low-slope roofs – the most common application for residential and commercial buildings
- Commercial and industrial rooftops – warehouses, office buildings, retail centers
- Roofs with irregular shapes or penetrations – SPF conforms to any geometry and seals around vents, pipes, and equipment
- Roof retrofits – can be applied over most existing roofing materials without tear-off
It is not typically used on steep-slope residential roofs where other systems are more practical.
Yes. One of the key advantages of spray polyurethane foam roofing is that it can be applied directly over most existing roof types, including:
- Built-up roofing (BUR)
- Modified bitumen
- Single-ply membranes (TPO, EPDM) – in many cases
- Metal roofing
- Concrete and wood decking
This eliminates the cost and disruption of a full tear-off and reduces installation time significantly. Our team inspects the existing roof before any application to confirm surface condition and compatibility.
A properly installed SPF roofing system lasts 20 to 30 years or more. The foam itself does not degrade, but the protective topcoat requires periodic maintenance:
- Initial coating lasts approximately 10 to 15 years before recoating is needed
- Recoating restores the UV and weather protection and extends the system’s life by another 10 to 15 years
- With regular inspections and timely recoating, an SPF roof can remain in service indefinitely
This makes foam roofing one of the most renewable and cost-effective long-term roofing options for commercial buildings.
Spray foam roofing cost depends on several factors:
- Roof area – total square footage
- Existing roof condition – whether repairs or additional prep work are needed
- Foam thickness – typically 1 to 1.5 inches for roofing applications
- Coating type and thickness – silicone, acrylic, or polyurethane topcoat
- Roof complexity – number of penetrations, drains, parapets, and equipment

SPF can be applied with built-in slope to direct water toward drains and eliminate low spots where water collects. This is one of its key advantages over flat membrane systems – the foam thickness can be varied across the roof surface to create positive drainage without structural changes.
For roofs with existing ponding issues, SPF is often the most cost-effective solution because it corrects drainage and waterproofs the surface in the same installation.
Modern SPF roofing products are:
- Free of CFCs and HCFCs – ozone-depleting compounds no longer used in current formulations
- ENERGY STAR and LEED compatible – the insulation performance helps buildings qualify for energy efficiency credits
- Renewable – the recoating model means the system does not end up in a landfill at the end of its life, unlike tear-off roofing systems
The energy savings generated by SPF’s insulation performance also reduce a building’s overall carbon footprint over time.
