ROOF COATINGSilicone & Acrylic

In Otay Mesa, coating a low-slope roof costs a fraction of replacing it and stops the leaks the same week. Hot, dry summers and sharp swings between day and night work the membrane and its laps until the surface gives up.

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.

How we work in Otay Mesa

Rake and eave metal is new on every job; reusing bent metal is false economy.

• Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
• Synthetic underlayment goes down over the whole deck, not just the valleys.
• Keep the paperwork: it transfers if you sell the house.
• We check the attic as well as the roof; half of what we find shows from underneath.

What the work looks like

• 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

When we tell you not to coat

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

Two coating systems, one right answer

• 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 cost side of coating

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.

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

On the ground in Otay Mesa

Nobody roofs Otay Mesa the way they roof a tract in the desert, and sun exposure here is relentless from April through October. We cover Otay Mesa from about 140 miles southeast, close enough for emergency calls.

Neighbouring work in San Ysidro, Chula Vista and Imperial Beach means materials are already staged nearby.

• Skylights are flashed new rather than reused, because that is where the next leak starts.
• We photograph every penetration before and after, so the file shows the work.
• Access gets planned first - driveway, staging, dumpster placement - so the street stays usable.
• Tile is sorted and reused where it is sound, which keeps the roof looking original.
• Magnet sweeps run morning and evening, which matters on a street with kids and bare feet.

Leaks found in summer cost a fraction of the same leak found in February. Call and we will look at the Otay Mesa roof, show you photos, and put the price in writing.

Serving Otay Mesa and nearby

We coat commercial and residential low-slope roofs throughout Otay Mesa and the surrounding San Diego County communities, including San Ysidro, Chula Vista and Imperial Beach.

What we look for on a Otay Mesa roof

Good candidates for coating tend to have:

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