San Angelo Roof Pros provides professional chimney flashing in San Angelo, TX for residential and commercial properties across the Concho Valley. Chimney leaks are the most misdiagnosed water problem we see, and the most commonly patched with sealant that lasts a season. The joint between masonry and roof is a movement joint. Two materials that expand at different rates meet there, and anything rigid across that gap is going to fail.
Done properly it is two separate layers of metal. Step flashing woven into each shingle course and turned up the masonry face. Then counterflashing cut into a mortar joint with a grinder, folded into the cut, sealed and lapped down over the step flashing. The two layers slide against each other as things move. Neither one is asked to bridge the joint on its own.
What we usually find instead is a single L-shaped piece face-nailed to the brick with a bead of caulk along the top edge. That is not flashing. It works until the sealant shrinks, which under this sun happens quickly, and then the water runs behind it and down the inside of the chase where you cannot see it until the ceiling below tells you.
The cricket is the other half. Once a chimney is wider than roughly thirty inches on the slope, it needs a saddle built on its uphill side to split water around it, and on an older board deck that saddle wants a solid base laid over the boards rather than framing set into whatever the gaps allow. Without one, the uphill face collects water and debris and stays wet after every storm.
Masonry condition sets the limit on what flashing can do. Open head joints, a spalled crown, a missing cap or badly weathered brick will feed water into the chase no matter how good the metal is. We inspect the crown and the top three courses and tell you plainly whether the leak you have is a roofing repair, a masonry repair, or both.
Metal chases get their own treatment. Rusted or undersized chase covers get replaced in stainless or heavy galvanized with a proper cross-break so water runs off instead of ponding in the middle, a folded drip edge on all four sides, a storm collar seated on the pipe rather than sealed to it, and a rain cap of the right diameter. The base flashing is then tied in with the same two-layer method a masonry chimney gets.
Our licensed and insured team brings the right materials and equipment to every job — 1x6 board decking, 7/16 inch OSB sheathing overlay, ring-shank roofing nails, UL 2218 Class 4 impact-rated laminates, self-adhered valley membrane, R-panel over 1x4 wood battens — and backs the work with a written workmanship warranty. We serve San Angelo and nearby communities including Grape Creek, Christoval, Miles, Rowena.

Materials, equipment and how we do chimney flashing
The difference between chimney flashing that lasts and chimney 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 board decking, 7/16 inch OSB sheathing overlay, ring-shank roofing nails, UL 2218 Class 4 impact-rated laminates, 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 San Angelo 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 Concho Valley means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why San Angelo Chooses San Angelo Roof Pros
- ✓We open a test area and measure the board gaps before writing a replacement estimate, so the sheathing quantity is measured rather than discovered mid-job.
- ✓Every proposal names a fastening pattern and a nail length, because on a plank deck the fastener decides the outcome more than the shingle brand does.
- ✓Hail inspections are recorded by slope aspect with ten-foot test squares, so a west elevation is never averaged against a sheltered north one.
- ✓We will recommend metal panel over new battens on outbuildings when it saves you the cost of a sheathing overlay entirely.
The standards behind chimney flashing
Quality here is not a matter of opinion — it is written down. The chimney flashing work we do in San Angelo follows published industry standards: NRCA publishes the Roofing Manual, the industry's reference for details and slope minimums, and Asphalt Roofing Manufacturers Association sets the shingle application and ventilation guidance the warranties reference. If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
