ROOF COATINGSilicone & Acrylic

In SoMa, coating a low-slope roof costs a fraction of replacing it and stops the leaks the same week. 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 roof coating costs in SoMa

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

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.

How we coat a roof in SoMa

• 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

What you get out of it

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.

The things that actually matter

You get a start date and a finish date in writing, and we hold them.

• Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
• Warranty paperwork is registered for you, not left in a folder for you to chase.
• Change orders are written and signed, never verbal.
• One person runs your job and answers the phone the whole way through.

Why SoMa roofs wear the way they do

Nobody roofs SoMa the way they roof a tract in the desert, and salt air and long damp mornings keep fasteners and flashings working hard. At about 337 miles northwest, SoMa is an easy run for us, inspection or emergency.

We are in Mission Bay, Hayes Valley and Financial District constantly, and the housing stock is much the same.

• Chimney and wall flashings are replaced, not painted over with sealant.
• We photograph every penetration before and after, so the file shows the work.
• Tile is sorted and reused where it is sound, which keeps the roof looking original.
• Material is delivered the morning of the job, not left on the driveway for a week.
• We work around tenants and business hours where the building is occupied.

A roof opened in October is a different job from one opened in January. Everything starts with a free inspection and a written number for your SoMa property.

What we look for on a SoMa roof

We usually recommend coating when the roof shows:

• Low spots that hold water for days after a storm
• Seams and laps that have opened up and started weeping
• A building that cooks in summer and runs the air conditioning hard
• 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

Serving SoMa and nearby

We coat commercial and residential low-slope roofs throughout SoMa and the surrounding San Francisco County communities, including Mission Bay, Hayes Valley and Financial District.

Choosing the system for your SoMa 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.

The honest version

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