ROOF COATINGSilicone & Acrylic

Restoring a Diamond Heights low-slope roof means fixing what is wrong first, then coating the whole surface seamless. 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.

Standards we hold on every Diamond Heights job

Soft decking gets replaced, not covered - we quote a sheet count and show you the bad bays.

• Rake and eave metal is new on every job; reusing bent metal is false economy.
• Intake and exhaust are balanced on the same visit - a sealed attic cooks a new roof early.
• You get a start date and a finish date in writing, and we hold them.
• Drone shots cover the steep sections, and the rest is checked on foot.

Does your Diamond Heights roof need coating?

Good candidates for coating tend to have:

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

The honest version

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

The cost side of coating

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

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

Choosing the system for your Diamond Heights 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.

Local conditions in Diamond Heights

Across San Francisco County, Diamond Heights has its own wear pattern, because fog drip keeps the north side wet long enough to grow moss. The shop is about 336 miles northwest, which is why we can be out the same day.

The roofs in Glen Park, Noe Valley and Twin Peaks are built much the same way, and they fail the same way.

• Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
• Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.
• Chimney and wall flashings are replaced, not painted over with sealant.
• 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.

We would rather be on your roof in September than during the first atmospheric river. Everything starts with a free inspection and a written number for your Diamond Heights property.
