El Monte Roof Pros provides professional chimney & wall flashing in El Monte, CA for residential and commercial properties across the San Gabriel Valley. Counterflashing is cut into masonry at a fixed height. Add a covering to the roof and that height shrinks, because the field rose and the reglet did not. On a house recovered once, the flashing at the chimney is working with an inch less than it was designed to have.
That is the most common cause of chimney leaks we find here, and it is also why the leak often starts years after the reroof rather than immediately. The assembly still sheds ordinary rain. It fails when a wind-driven system pushes water up the vertical leg further than the reduced height allows. In this climate that happens two or three times a winter.
At that frequency a homeowner suspects the chimney crown, the cap, or the flue. The actual problem is six inches of sheet metal. So the fix has to restore the height rather than re-seal what is there. Step flashing behind the shingles is the other half, and on a recover it is almost never renewed. New field goes over old field and the original step pieces stay buried.
The water path that mattered is left in place with a decade of corrosion on it. We open a chimney to bare deck, weave new step pieces course by course, and cut a fresh reglet at the correct height. Two-piece counterflashing then lets the chimney be re-roofed later without cutting the masonry again. Crickets are worth arguing for. Any chimney wider than about thirty inches on the upslope side collects debris and water behind it.
A framed and flashed cricket moves both around the stack instead of holding them against it. Adding one during a tear-off is a modest cost; adding one later means opening a finished roof. A cricket also sheds the debris that turns a chimney back into a planter every autumn. The same reasoning applies at every wall a roof meets.
Here that means the transition into a two-storey addition and the head of any patio cover tied into the fascia. Both want base flashing under the field, counterflashing in fresh reglet, and a kickout at the bottom of the run. The kickout is the cheapest piece of metal on the roof and the most often left off. Both details are cheap during a tear-off and both explain the staining on the stucco below.
Our licensed and insured team brings the right materials and equipment to every job — 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, architectural laminate shingles, stone-coated steel panel — and backs the work with a written workmanship warranty. We serve El Monte and nearby communities including South El Monte, Rosemead, Temple City, Baldwin Park.

Materials, equipment and how we do chimney & wall flashing
The difference between chimney & wall flashing that lasts and chimney & wall flashing 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.
