El Monte Roof Pros provides professional roof coatings & sealing in El Monte, CA for residential and commercial properties across the San Gabriel Valley. This is the page where we argue against the product more often than for it. A coating over two layers of composition shingle is money spent on a roof you are still going to tear off, and it does not make the tear-off cheaper. It makes it heavier.
The reason is what a coating is for. Elastomeric and silicone systems are membrane restoration products. They renew a monolithic surface that is already sound and continuous, which means a single ply, a smooth built-up assembly, a foam roof, or metal. They do not bridge the lap joints of a shingle field, they do not reach the fasteners, and they cannot fix a nail that never reached the deck.
On a layered shingle roof a coating seals the top surface of a problem living two inches underneath it, and it hides the evidence you would need to diagnose that problem later. A homeowner who coats a shingle roof usually calls us two years later with the same leak and a harder job. Where coatings are genuinely right, they are the best value in roofing.
A twenty-year-old sixty-mil membrane with sound seams and dry insulation, recoated in silicone at proper mil thickness after a wash and seam treatment, buys ten or more years for a fraction of a replacement. Aged smooth modified bitumen behaves the same way, and tight-seamed metal takes coating well once rust is prepared and fasteners are gasketed. We measure wet film thickness as we go, because a silicone system applied thin fails at the seams first.
The qualifying test is short and we run it before quoting. Core the assembly to confirm dry insulation. Probe the seams. Check adhesion with a pull test on a small patch rather than on faith. Confirm the substrate is not already carrying two coverings. If any of those fail we say so and quote the work that applies. All four checks together take under two hours and cost far less than a coating that will not stick.
There is a real secondary benefit worth naming. A reflective surface on a low-slope section drops peak temperature substantially, which slows the thermal cycling that opens seams in the first place and helps on the energy side of a permit review. That is a reason to coat a roof that qualifies, not a reason to coat one that does not.

Materials, equipment and how we do roof coatings & sealing
The difference between roof coatings & sealing that lasts and roof coatings & sealing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with 1x6 skip sheathing, the two-covering limit in the California Residential Code, dead load in pounds per square foot, half-inch CDX and seven-sixteenths OSB re-decking, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every El Monte job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the San Gabriel Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

- ✓Ventilation is sized by published net free area against attic floor area, not by counting vents on the roof
- ✓Counterflashing is cut into a fresh reglet at the correct height for the finished roof rather than re-sealed at the old one
