Roof Coating Chinatown

A cool roof coating turns a hot, chalked Chinatown roof into a sealed, reflective surface. 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 Chinatown 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.

Pricing a Chinatown roof coating

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.

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.

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

When we tell you not to coat

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

When coating makes sense in Chinatown

We usually recommend coating when the roof shows:

• Low spots that hold water for days after a storm
• 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
• Seams and laps that have opened up and started weeping
• A roof with years left in the deck and insulation underneath

Serving Chinatown and nearby

We coat commercial and residential low-slope roofs throughout Chinatown and the surrounding San Francisco County communities, including North Beach, Nob Hill and Financial District.

What the work looks like in Chinatown

Change orders are written and signed, never verbal.

• Ice-and-water goes in at the valleys and penetrations even though it rarely freezes here.
• Workmanship coverage is ours to honour, and we are still here to honour it.
• You get a start date and a finish date in writing, and we hold them.
• Intake and exhaust are balanced on the same visit - a sealed attic cooks a new roof early.

What the street looks like in Chinatown

Most of what we fix in Chinatown traces back to one thing: whatever fails first on these roofs fails at the edges. From the yard it is roughly 338 miles northwest to Chinatown - no travel surcharge, no week-long wait.

We are in North Beach, Nob Hill and Financial District constantly, and the housing stock is much the same.

• Skylights are re-flashed as part of the job rather than quoted as an extra later.
• Material is delivered the morning of the job, not left on the driveway for a week.
• Tear-off debris leaves the same day; nobody is left with a pile over the weekend.
• Skylights are flashed new rather than reused, because that is where the next leak starts.
• Chimney and wall flashings are replaced, not painted over with sealant.

A roof opened in winter costs more and risks more, so we plan around the forecast. We will tell you if the roof has five years left, because that is also useful to know.

Silicone or acrylic for a Chinatown 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.

What this costs in Chinatown, honestly

Dry-season work is cheaper and safer, because the whole job happens on dry decking. Once the first storm is on the ten-day forecast the calendar in Chinatown tightens fast, and emergency work costs more than planned work.

We do not use subcontract crews we have never met. The people on your Chinatown roof are the people we train, and they carry our workers' compensation.

After the job in Chinatown

A roof is a system. The membrane or shingle gets the attention, but the underlayment, the fasteners, the edge metal and the ventilation decide whether it reaches its warranty.
