ROOF COATINGSilicone & Acrylic

Flat roof restoration in San Dimas starts with prep, not product. Hillside exposure means long afternoon sun and the first of the Santa Ana winds, which is hard on a flat roof's surface and its flashings.

Does your San Dimas roof need coating?

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

• Seams and laps that have opened up and started weeping
• Flashing and penetrations that leak while the field of the roof is still solid
• A roof with years left in the deck and insulation underneath
• A building that cooks in summer and runs the air conditioning hard
• Chalky, sun-baked membrane that has lost its surface but not its body

How long a San Dimas 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.

How we coat a roof in San Dimas

• 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

Choosing the system for your San Dimas 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 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.

What separates a good job from a cheap one

We do not ask for large deposits before material is delivered.

• We check the attic as well as the roof; half of what we find shows from underneath.
• Synthetic underlayment goes down over the whole deck, not just the valleys.
• You get a text when the crew is coming and a walk-through when they are done.
• Weather delays are called early rather than left to surprise you.

Serving San Dimas and nearby

We coat commercial and residential low-slope roofs throughout San Dimas and the surrounding Los Angeles County communities, including La Verne, Glendora and Pomona.

When coating is the wrong call

If we find saturated insulation or a failing deck on your San Dimas roof, we say so. Coating over a wet roof traps the water and costs you twice.

What changes on a San Dimas roof

Roof life in San Dimas is decided by exposure more than brand, and sun on the exposed slopes dries out the cheap underlayments early. San Dimas is around 25 miles east of the shop, which keeps scheduling simple.

La Verne, Glendora and Pomona are on the same route, which keeps follow-ups easy.

• We work around tenants and business hours where the building is occupied.
• We protect landscaping and the pool before a single bundle comes off the truck.
• Dry-in happens the same day the old roof comes off; nothing sits open overnight.
• Gutters are pulled and refitted where they block a proper drip edge.
• Solar panels get detached and reset on a schedule that matches the roofing crew.

Scheduling before the rains means the whole job happens on dry decking. You get photos, measurements and a plain explanation before any work is booked.
