ROOF COATINGSilicone & Acrylic

Most Dogpatch flat roofs do not need tearing off — they need cleaning, repairing and sealing. 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.

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 Dogpatch roof needs replacing instead.

Why Dogpatch roofs fail where they do

Ask ten Dogpatch owners about their roof and you get the same complaints: nothing dries quickly here, so a small leak stays wet. 335 miles northwest means a crew, a ladder and a tarp can be there this afternoon.

Neighbouring work in Potrero Hill, Mission Bay and Bayview means materials are already staged nearby.

• Material is delivered the morning of the job, not left on the driveway for a week.
• Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
• Skylights are flashed new rather than reused, because that is where the next leak starts.
• Gutters are pulled and refitted properly instead of being crushed by a ladder.
• Permits and inspections run through the local building department, and we pull them rather than leaving it to you.

We would rather find the problem in the dry months and fix it on a schedule. Everything starts with a free inspection and a written number for your Dogpatch property.

Serving Dogpatch and nearby

We coat commercial and residential low-slope roofs throughout Dogpatch and the surrounding San Francisco County communities, including Potrero Hill, Mission Bay and Bayview.

Choosing the system for your Dogpatch 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 things that actually matter

Edges are fastened to spec because that is where uplift starts.

• Fascia and rafter tails get checked while the edge is open.
• Ventilation gets looked at while the roof is open; most Dogpatch attics run hotter than they should.
• Synthetic underlayment goes down over the whole deck, not just the valleys.
• Moisture readings go in the report where a leak is suspected but not obvious.

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

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.

What roof coating costs in Dogpatch

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.

Does your Dogpatch roof need coating?

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

• 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
• Low spots that hold water for days after a storm
• A building that cooks in summer and runs the air conditioning hard
