Roof Coating San Diego

A cool roof coating turns a hot, chalked San Diego 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.

Silicone or acrylic for a San Diego 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 we look for on a San Diego roof

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

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

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 San Diego 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.

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 San Diego and nearby

We coat commercial and residential low-slope roofs throughout San Diego and the surrounding San Diego County communities, including La Mesa, Coronado and National City.

Why San Diego roofs wear the way they do

Most of what we fix in San Diego traces back to one thing: onshore wind drives rain sideways into the flashings. From the shop it is a 125-mile run southeast to San Diego, so emergencies get a same-day answer.

Jobs in La Mesa, Coronado and National City run alongside this one most weeks.

• We photograph every penetration before and after, so the file shows the work.
• Solar gets detached and reset by a licensed crew, not improvised around.
• Permits and inspections run through the local building department, and we pull them rather than leaving it to you.
• Solar panels get detached and reset on a schedule that matches the roofing crew.
• Gutters are pulled and refitted properly instead of being crushed by a ladder.

We would rather find the problem in the dry months and fix it on a schedule. Ask for the inspection, keep the report, and decide in your own time.

How we work in San Diego

Synthetic underlayment goes down over the whole deck, not just the valleys.

• Drip edge and starter course get installed properly - that is half the wind resistance.
• We show you the soft spots before they are covered, not after.
• Workmanship coverage is ours to honour, and we are still here to honour it.
• Change orders are written and signed, never verbal.

How long a San Diego 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.

What goes wrong when it is done cheap

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

Before we quote we check the deck, the ventilation, the flashings and the drainage. Three of those four are invisible from the ground, and all four decide how long the roof lasts.

What we check before quoting

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.
