ROOF COATINGSilicone & Acrylic

In Japantown, 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.

When coating makes sense in Japantown

A coating earns its keep on a roof with these problems:

• Chalky, sun-baked membrane that has lost its surface but not its body
• 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

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 Japantown roof needs replacing instead.

Pricing a Japantown roof 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 long a Japantown 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.

The coating process, step by step

• 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

Serving Japantown and nearby

We coat commercial and residential low-slope roofs throughout Japantown and the surrounding San Francisco County communities, including Western Addition, Pacific Heights and Hayes Valley.

Choosing the system for your Japantown 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.

A closer look at Japantown

There is nothing abstract about a Japantown roof: onshore wind drives rain sideways into the flashings. Being 338 miles northwest of Japantown, we can be on the roof before the next rain band arrives.

We work the same streets in Western Addition, Pacific Heights and Hayes Valley, so crews know the area and its roofs.

• Solar gets detached and reset by a licensed crew, not improvised around.
• Material is delivered the morning of the job, not left on the driveway for a week.
• 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.
• Gutters are pulled and refitted properly instead of being crushed by a ladder.

Scheduling before the rains means the whole job happens on dry decking. Ask for the inspection, keep the report, and decide in your own time.

Details that decide a Japantown roof

Weather delays are called early rather than left to surprise you.

• The site is cleaned daily, and the last magnet pass happens before the crew leaves.
• Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
• Rake and eave metal is new on every job; reusing bent metal is false economy.
• Payment is tied to progress, not demanded up front.
