Spray Foam Roofing Contractor in Bakersfield, CA

What is a spray foam roof?

A spray foam roof, also called an SPF (spray polyurethane foam) roof, is made by spraying two liquid ingredients onto the roof. They mix at the spray gun, expand, and harden within seconds into a rigid foam that sticks to the surface underneath. The crew builds the foam up to the thickness the roof needs, then covers it with a protective roof coating such as silicone or acrylic.

The result is a roof with:

• No seams. Most flat roofs leak at seams, laps and fasteners. Foam is one continuous layer across the whole roof, including around vents, pipes and HVAC curbs.
• Built-in insulation. The foam layer itself insulates the top of the building, which matters in a place where summer heat is the main enemy.
• Better drainage options. Foam can be sprayed thicker in some areas to help move water toward drains and away from low spots.
• Light weight. Foam adds far less weight than many other roof systems, which is one reason it can often go over an existing roof.
• A renewable surface. The coating on top is what faces the weather. Over time it can be cleaned and recoated to keep the foam protected, rather than tearing off the whole roof.

Why spray foam works in Bakersfield

Bakersfield roofs deal with long, hot summers, strong sun, dust, and a handful of real rainstorms each year. Dark, worn roofs absorb heat and pass it into the building. Seams and flashings dry out and crack, and then the first big storm finds them.

A foam roof answers both problems. The seamless foam keeps water out, and a light-colored coating on top reflects much of the sunlight that would otherwise heat the roof. For buildings that need to stay cool, like warehouses, packing and cold storage facilities, shops and offices, that combination is why foam is so common in hot climates.

If you're replacing or recovering a large part of a low-slope commercial roof, California's Title 24 energy code may require a reflective "cool roof." A coated foam roof is one way to approach that. We'll talk through what applies to your project. See Title 24 cool roofs.

Can spray foam go over my existing roof?

Often, yes. That's one of foam's biggest advantages. Many flat and low-slope roofs can be foamed over instead of torn off, which can mean less mess, less disruption and less debris hauled to the landfill.

It depends on what's under there. Before any foam goes on, the existing roof has to be checked. Wet or damaged materials need to be found and removed, the surface has to be cleaned and prepared, and the roof has to be able to take another layer under local code.

We'll tell you honestly whether your roof is a good candidate for foam, or whether it needs to come off first.

Spray foam over metal roofs

Old metal roofs are common on shops, barns, packing sheds, warehouses and industrial buildings around Kern County. As they age, the trouble usually starts in the same places: seams, overlaps and fasteners loosen or rust, and water finds its way in. Bare metal also gets very hot in the sun.

Spraying foam over an existing metal roof is how we typically restore metal roofs. The foam:

• Covers the seams, overlaps and fastener heads in one continuous layer, which are the spots where metal roofs usually leak.
• Adds insulation over what was a bare, heat-soaking surface.
• Keeps the existing metal in place. There's no tear-off of the panels in most cases.
• Gets a protective coating on top, just like any foam roof.

Not every metal roof is a good fit. Panels that are badly rusted through or structurally weak have to be dealt with first. We'll look at the roof and tell you what it needs. If you have a leaking metal building, call (661) 213-2203 or send us the details.

Spray foam over old gravel roofs

A lot of older commercial buildings around Bakersfield still have built-up gravel roofs. When they wear out, they crack and blister under the rock, and the leak usually shows up inside long before anyone can see where it started.

An old gravel roof doesn't always have to be torn off. When the roof underneath is dry and solid, we can:

• Remove the loose gravel and clean the surface.
• Find and cut out wet or damaged areas and repair them before any foam goes down. Foam never goes over wet insulation.
• Spray foam over the top in one seamless, insulating layer that covers the old seams and flashings.
• Finish it with a silicone or acrylic coating to protect the foam from the sun.

If the old roof is saturated or failing, we'll tell you, and a tear-off may be the better choice. Either way, you get the reasons in a written estimate. For the trade-offs, read roof replacement vs overlay, or call (661) 213-2203.

Foam roof repair and recoating

Already have a foam roof? Like any roof, it lasts longer with care. Common issues we look for include:

• Worn or thin coating, which leaves the foam exposed to the sun
• Blisters, cracks or damaged spots from foot traffic, equipment work or hail
• Bird pecking, a known problem on foam roofs
• Ponding areas where water sits after storms

Small areas can usually be repaired, and a worn roof can often be cleaned and recoated with silicone or acrylic to protect the foam for years to come. We repair and recoat foam roofs installed by other contractors too, not just our own. See our roof coatings page, or ask about a roof maintenance program.

How a spray foam roof project works

1. Call or request an estimate. Tell us about the building: size, roof type, and what's going wrong.
2. Roof evaluation. We check the existing roof to see whether it can be foamed over and what prep is needed.
3. Written, itemized estimate. You get the scope, the foam and coating plan, and the price, line by line. We pull the permits for the job.
4. Prep. Cleaning, removing any wet or damaged material, and securing loose areas.
5. Foam and coating. Foam goes on in layers to the planned thickness, followed by the protective coating. Spraying depends on the weather, since the surface needs to be dry and wind needs to be manageable.
6. Finished roof, with warranty. Warranty length depends on the roof system, typically 20 years.
