Roof Coating Telegraph Hill

Flat roof restoration in Telegraph Hill 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.

When coating makes sense in Telegraph Hill

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

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

Standards we hold on every Telegraph Hill job

We show you the soft spots before they are covered, not after.

• The written warranty names what is covered and for how long, with no asterisk games.
• Underlayment is where corners get cut; we use the system the manufacturer warrants.
• Weather delays are called early rather than left to surprise you.
• If the attic has no real intake, we fix that rather than leaving a new roof to bake.

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

When we tell you not to coat

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

What the street looks like in Telegraph Hill

Ask any crew that works San Francisco County and they will tell you the same thing - salt air and long damp mornings keep fasteners and flashings working hard. 338 miles northwest means a free inspection costs you nothing but an hour.

The same trucks cover North Beach, Russian Hill and Chinatown, which keeps callbacks quick.

• We work around tenants and business hours where the building is occupied.
• Satellite dishes and A/C line sets are re-flashed, not just set back down.
• Skylights are flashed new rather than reused, because that is where the next leak starts.
• Where an HOA sets colour or material rules, we match the approved list before the job is quoted.
• Gutters are pulled and refitted where they block a proper drip edge.

Insurance work moves faster when the damage is documented before the next storm. We will tell you if the roof has five years left, because that is also useful to know.

Serving Telegraph Hill and nearby

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

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.

How long a Telegraph Hill 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 cost side of coating

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.

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

Timing the work in Telegraph Hill

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

Cheap work shows up at the details: a flashing sealed instead of replaced, a vent reused because it was quicker, decking covered because nobody wanted the conversation. Those are the roofs we get called back to in two winters.

After the job in Telegraph Hill

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 Telegraph Hill tightens fast, and emergency work costs more than planned work.
