ROOF COATINGSilicone & Acrylic

Flat roof restoration in Hayes Valley starts with prep, not product. 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 the work looks like

• 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

How long a Hayes 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.

Hayes Valley, up close

Ask ten Hayes Valley owners about their roof and you get the same complaints: wind off the water drives rain sideways into laps that face it. Hayes Valley is around 337 miles northwest of the shop, which keeps scheduling simple.

The roofs in SoMa, Western Addition and Castro are built much the same way, and they fail the same way.

• Gutters are pulled and refitted properly instead of being crushed by a ladder.
• Solar gets detached and reset by a licensed crew, not improvised around.
• Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.
• Skylights are flashed new rather than reused, because that is where the next leak starts.
• We photograph every penetration before and after, so the file shows the work.

A roof opened in winter costs more and risks more, so we plan around the forecast. Nothing is booked until you have photos, a scope and a written price.

When we tell you not to coat

Coating is not for every roof. If the deck is soft, the insulation is wet or the membrane is finished, a coating only hides the problem — we will tell you the Hayes Valley roof needs replacing instead.

Choosing the system for your Hayes 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 Hayes Valley

Good candidates for coating tend to have:

• 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
• Low spots that hold water for days after a storm
• Seams and laps that have opened up and started weeping
• Flashing and penetrations that leak while the field of the roof is still solid

The cost side of coating

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 run the job in Hayes Valley

Drone shots cover the steep sections, and the rest is checked on foot.

• We show you the soft spots before they are covered, not after.
• Edges are fastened to spec because that is where uplift starts.
• 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.
