Telegraph Hill Roof Coating

A roof coating buys years back on a Telegraph Hill flat roof that is weathered but still sound. 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.

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.

Pricing a Telegraph Hill 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.

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

A closer look at Telegraph Hill

Nobody roofs Telegraph Hill the way they roof a tract in the desert, and the same three details cause most of the leaks we are called out for. Being 338 miles northwest of Telegraph Hill, we can be on the roof before the next rain band arrives.

You will see our trucks in North Beach, Russian Hill and Chinatown on the same run.

• Gutters are pulled and refitted properly instead of being crushed by a ladder.
• 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.
• Tear-off debris leaves the same day; nobody is left with a pile over the weekend.
• Gutters are pulled and refitted where they block a proper drip edge.

We would rather find the problem in the dry months and fix it on a schedule. You get photos, measurements and a plain explanation before any work is booked.

When we tell you not to coat

If we find saturated insulation or a failing deck on your Telegraph Hill roof, we say so. Coating over a wet roof traps the water and costs you twice.

How we coat a roof in Telegraph Hill

• 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

Choosing the system for your Telegraph Hill 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 we look for on a Telegraph Hill roof

We usually recommend coating when the roof shows:

• A roof with years left in the deck and insulation underneath
• Low spots that hold water for days after a storm
• Chalky, sun-baked membrane that has lost its surface but not its body
• Flashing and penetrations that leak while the field of the roof is still solid
• Seams and laps that have opened up and started weeping

Ridge venting goes in where the roof line allows it, with proper intake at the eaves.

• Most homes take two to four days once material lands.
• Keep the paperwork: it transfers if you sell the house.
• You get a text when the crew is coming and a walk-through when they are done.
• We do not ask for large deposits before material is delivered.

Questions Telegraph Hill owners ask us

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.

Price follows the roof, not a rate card: access, pitch, material, how many layers come off and what the deck looks like underneath. We measure in person, show you photos and put the number in writing before anything is booked.

What this costs in Telegraph Hill, honestly

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.
