ROOF COATINGSilicone & Acrylic

Restoring a Cole Valley low-slope roof means fixing what is wrong first, then coating the whole surface seamless. 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.

What we look for on a Cole Valley roof

We usually recommend coating when the roof shows:

• Seams and laps that have opened up and started weeping
• Chalky, sun-baked membrane that has lost its surface but not its body
• Flashing and penetrations that leak while the field of the roof is still solid
• Low spots that hold water for days after a storm
• A roof with years left in the deck and insulation underneath

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

The honest version

A coating needs a dry, sound roof underneath. When a Cole Valley roof does not have that, the honest answer is a replacement, and we will quote it that way.

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.

Working in Cole Valley

Before materials come into it, the site decides the job: in Cole Valley, the weather here punishes details, not products. From the shop it is a 338-mile run northwest to Cole Valley, so emergencies get a same-day answer.

Jobs in Haight Ashbury, Inner Sunset and Castro run alongside this one most weeks.

• Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.
• Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
• Skylights are re-flashed as part of the job rather than quoted as an extra later.
• Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
• Material is delivered the morning of the job, not left on the driveway for a week.

Dry-season work books up fast, so the calendar tightens once the first storm forecast lands. We will tell you if the Cole Valley roof has years left in it rather than sell you a new one.

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.

Lifespan and recoating

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.

What roof coating costs in Cole Valley

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.

Because the work is additive, most buildings stay open and in use while we are on the roof.
