Roof Coating Cow Hollow

A cool roof coating turns a hot, chalked Cow Hollow roof into a sealed, reflective surface. 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 Cow Hollow 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

Does your Cow Hollow roof need coating?

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

• A roof with years left in the deck and insulation underneath
• Low spots that hold water for days after a storm
• 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 building that cooks in summer and runs the air conditioning hard

What you get out of it

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 Cow Hollow

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.

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.

Serving Cow Hollow and nearby

We coat commercial and residential low-slope roofs throughout Cow Hollow and the surrounding San Francisco County communities, including Marina District, Pacific Heights and Presidio Heights.

What you can expect from us

Change orders are written and signed, never verbal.

• Warranty paperwork is registered for you, not left in a folder for you to chase.
• Ventilation gets looked at while the roof is open; most Cow Hollow attics run hotter than they should.
• Fascia and rafter tails get checked while the edge is open.
• Underlayment is where corners get cut; we use the system the manufacturer warrants.

Silicone or acrylic for a Cow Hollow 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 changes on a Cow Hollow roof

What a roof faces in Cow Hollow is specific, not generic: whatever fails first on these roofs fails at the edges. Our shop sits about 339 miles northwest of Cow Hollow, so a crew is on site the same morning.

The roofs in Marina District, Pacific Heights and Presidio Heights are built much the same way, and they fail the same way.

• We work around tenants and business hours where the building is occupied.
• Tile is sorted and reused where it is sound, which keeps the roof looking original.
• Solar panels get detached and reset on a schedule that matches the roofing crew.
• We protect landscaping and the pool before a single bundle comes off the truck.
• Skylights are flashed new rather than reused, because that is where the next leak starts.

We would rather find the problem in the dry months and fix it on a schedule. No pressure, no same-day-only discount, no hard close.

Questions Cow Hollow owners ask us

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 Cow Hollow tightens fast, and emergency work costs more than planned work.

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 Cow Hollow

The questions we hear most in Cow Hollow are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
