ROOF COATINGSilicone & Acrylic

In Mission District, 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.

How long a Mission District 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 Mission District and nearby

We coat commercial and residential low-slope roofs throughout Mission District and the surrounding San Francisco County communities, including Noe Valley, Potrero Hill and Bernal Heights.

What roof coating costs in Mission District

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.

When coating makes sense in Mission District

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

• Low spots that hold water for days after a storm
• Chalky, sun-baked membrane that has lost its surface but not its body
• A roof with years left in the deck and insulation underneath
• A building that cooks in summer and runs the air conditioning hard
• Seams and laps that have opened up and started weeping

Local notes for Mission District

Ask any crew that works San Francisco County and they will tell you the same thing - the same three details cause most of the leaks we are called out for. We are 336 miles northwest of Mission District; crews pass through most days anyway.

You will see our trucks in Noe Valley, Potrero Hill and Bernal Heights on the same run.

• Satellite dishes and A/C line sets are re-flashed, not just set back down.
• We photograph every penetration before and after, so the file shows the work.
• Tear-off debris leaves the same day; nobody is left with a pile over the weekend.
• Tile is sorted and reused where it is sound, which keeps the roof looking original.
• We work around tenants and business hours where the building is occupied.

The first big storm books out the whole trade, so earlier is cheaper. No pressure, no same-day-only discount, no hard close.

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

Two coating systems, one right answer

• 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.

Standards we hold on every Mission District job

We photograph every slope and penetration so you see what we see before deciding anything.

• Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
• We show you the soft spots before they are covered, not after.
• Driveways get swept and gutters cleared as part of the job, not as an extra.
• Ice-and-water goes in at the valleys and penetrations even though it rarely freezes here.

When we tell you not to coat

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