ROOF COATINGSilicone & Acrylic

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

When coating makes sense in Duarte

We usually recommend coating when the roof shows:

• Seams and laps that have opened up and started weeping
• A building that cooks in summer and runs the air conditioning hard
• A roof with years left in the deck and insulation underneath
• 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 roof coating costs in Duarte

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.

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.

Duarte roofs, specifically

We work on Duarte roofs most weeks, and the pattern is consistent: the slopes take the wind first and hold the afternoon sun longest. 16 miles east means a free inspection costs you nothing but an hour.

We are often working Bradbury, Monrovia and Irwindale in the same week, which keeps costs sensible.

• Skylights are flashed new rather than reused, because that is where the next leak starts.
• Dry-in happens the same day the old roof comes off; nothing sits open overnight.
• Gutters are pulled and refitted properly instead of being crushed by a ladder.
• Solar panels get detached and reset on a schedule that matches the roofing crew.
• Gutters are pulled and refitted where they block a proper drip edge.

Book in the dry months and the whole job happens on dry decking. If a repair solves it, we quote the repair instead of selling a replacement.

Choosing the system for your Duarte 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.

How long a Duarte 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 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

Serving Duarte and nearby

We coat commercial and residential low-slope roofs throughout Duarte and the surrounding Los Angeles County communities, including Bradbury, Monrovia and Irwindale.

When we tell you not to coat

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

Before, during and after

You get a text when the crew is coming and a walk-through when they are done.

• Fascia and rafter tails get checked while the edge is open.
• Drip edge and starter course get installed properly - that is half the wind resistance.
• Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
• Payment is tied to progress, not demanded up front.
