ROOF COATINGSilicone & Acrylic

Most Cole Valley flat roofs do not need tearing off — they need cleaning, repairing and sealing. Salt air, marine layer and long damp mornings keep a low-slope roof wet longer, so seams and ponding spots are where the trouble starts.

Pricing a Cole Valley roof coating

Coating is priced by the square foot once we know the condition and how much prep the roof needs, and the number comes to you in writing before anything starts.

A coating runs well under the cost of a tear-off and replacement, and there is no dumpster, no demolition and no days of noise over the tenants' heads.

When we tell you not to coat

If we find saturated insulation or a failing deck on your Cole Valley roof, we say so. Coating over a wet roof traps the water and costs you twice.

How long a Cole Valley roof coating lasts

A silicone system at the right thickness over a properly prepped roof gives you ten years and up, and acrylic is close behind on a roof that drains well. Both systems are renewable: when the time comes you wash the roof and add another coat instead of starting over, which is why building owners keep coming back to them.

Serving Cole Valley and nearby

We coat commercial and residential low-slope roofs throughout Cole Valley and the surrounding San Francisco County communities, including Haight Ashbury, Inner Sunset and Castro.

Silicone or acrylic for a Cole Valley roof?

• Silicone: the pick for roofs that pond. It handles standing water, resists UV without turning brittle, and lasts longest of the two.
• Acrylic: the pick for roofs that drain clean. Lower cost per square, excellent reflectivity, and easy to recoat later.
• Both go down seamless, so there are no laps or fasteners for water to work into.
• Both drop the roof surface temperature sharply, which shows up on the cooling bill of a conditioned building.

When coating makes sense in Cole Valley

Good candidates for coating tend to have:

• A roof with years left in the deck and insulation underneath
• A building that cooks in summer and runs the air conditioning hard
• Flashing and penetrations that leak while the field of the roof is still solid
• Low spots that hold water for days after a storm
• Seams and laps that have opened up and started weeping

How we coat a roof in Cole Valley

• Inspect and measure, including core tests where we need to know what is under the membrane
• Clean the roof — power wash, remove dirt, chalk and loose coating
• Repair: cracks, open seams, failed flashing, blisters and bad penetrations
• Prime where the substrate calls for it
• Apply the coating in multiple passes to the specified thickness, seams and details first
• Final walk for even coverage and thickness, then clean up the site

A roofer's read on Cole Valley

Roofs in Cole Valley do not wear out the way a brochure says they do, and salt air and long damp mornings keep fasteners and flashings working hard. Being 338 miles northwest of Cole Valley, we can be on the roof before the next rain band arrives.

The same trucks cover Haight Ashbury, Inner Sunset and Castro, which keeps callbacks quick.

• Chimney and wall flashings are replaced, not painted over with sealant.
• We photograph every penetration before and after, so the file shows the work.
• Gutters are pulled and refitted where they block a proper drip edge.
• Satellite dishes and A/C line sets are re-flashed, not just set back down.
• Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.

Insurance work moves faster when the damage is documented before the next storm. If a repair solves it, we quote the repair instead of selling a replacement.

The parts people ask about

Deck repairs are priced per sheet so there is no surprise number halfway through.

• Synthetic underlayment goes down over the whole deck, not just the valleys.
• An inspection here means walking the roof, not pointing a camera at it from the driveway.
• Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
• Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
