ROOF COATINGSilicone & Acrylic

A roof coating buys years back on a Diamond Heights 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.

Does your Diamond Heights roof need coating?

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
• Seams and laps that have opened up and started weeping
• A roof with years left in the deck and insulation underneath
• Chalky, sun-baked membrane that has lost its surface but not its body

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.

The honest version

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 Diamond Heights roof needs replacing instead.

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

Pricing a Diamond Heights 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.

Serving Diamond Heights and nearby

We coat commercial and residential low-slope roofs throughout Diamond Heights and the surrounding San Francisco County communities, including Glen Park, Noe Valley and Twin Peaks.

Why Diamond Heights roofs fail where they do

We work on Diamond Heights roofs most weeks, and the pattern is consistent: nothing dries quickly here, so a small leak stays wet. We are 336 miles northwest of Diamond Heights; crews pass through most days anyway.

We know Glen Park, Noe Valley and Twin Peaks as well as we know Diamond Heights.

• Solar gets detached and reset by a licensed crew, not improvised around.
• Tear-off debris leaves the same day; nobody is left with a pile over the weekend.
• We photograph every penetration before and after, so the file shows the work.
• Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
• Chimney and wall flashings are replaced, not painted over with sealant.

Dry-season work books up fast, so the calendar tightens once the first storm forecast lands. We will tell you if the roof has five years left, because that is also useful to know.

How long a Diamond Heights 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.

Standards we hold on every Diamond Heights job

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

• Financing exists if you want it, and nobody pushes it on you.
• Drip edge and starter course get installed properly - that is half the wind resistance.
• Workmanship coverage is ours to honour, and we are still here to honour it.
• Deck repairs are priced per sheet so there is no surprise number halfway through.
