ROOF COATINGSilicone & Acrylic

In Mission Bay, 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 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 Mission Bay roof needs replacing instead.

What roof coating costs in Mission Bay

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

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.

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 Mission Bay and nearby

We coat commercial and residential low-slope roofs throughout Mission Bay and the surrounding San Francisco County communities, including Dogpatch, SoMa and Potrero Hill.

The parts people ask about

We do not ask for large deposits before material is delivered.

• Synthetic underlayment goes down over the whole deck, not just the valleys.
• Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
• Edges are fastened to spec because that is where uplift starts.
• Keep the paperwork: it transfers if you sell the house.

Does your Mission Bay roof need coating?

We usually recommend coating when the roof shows:

• Flashing and penetrations that leak while the field of the roof is still solid
• 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
• A roof with years left in the deck and insulation underneath
• Low spots that hold water for days after a storm

What we see on Mission Bay roofs

Ask ten Mission Bay owners about their roof and you get the same complaints: onshore wind drives rain sideways into the flashings. From the shop it is a 336-mile run northwest to Mission Bay, so emergencies get a same-day answer.

You will see our trucks in Dogpatch, SoMa and Potrero Hill on the same run.

• Skylights are re-flashed as part of the job rather than quoted as an extra later.
• Gutters are pulled and refitted where they block a proper drip edge.
• We work around tenants and business hours where the building is occupied.
• Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
• Where an HOA sets colour or material rules, we match the approved list before the job is quoted.

The first big storm books out the whole trade, so earlier is cheaper. The inspection is free, and so is the second opinion if you already have a quote.

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.

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.
