San Angelo Roof Pros provides professional flat & low-slope roofing in San Angelo, TX for residential and commercial properties across the Concho Valley. Downtown San Angelo and the older commercial strips run on low-slope roofs, and a large share of those sit on wood decking rather than steel or concrete. That is the part that gets skipped in a quote, and it is the part that decides whether a new membrane behaves.
Under a forty-year-old built-up roof you often find planking, a layer of fiberboard, and gravel that has been there so long it has bedded into the asphalt. Pulling all that off is the honest starting point, because a membrane fastened into soft or gapped wood pulls loose at the seams under wind, and the seams are the only thing holding a mechanically attached system down.
Drainage comes next and it is the local weakness. A roof laid out around a slow steady rainfall behaves badly when three inches arrive in ninety minutes. Internal drains sized generations ago back up, scuppers that were adequate for decades overflow, and water stands long enough to matter to the deck below. We survey with a level and a hose first, and we chalk the low spots on the roof so you can see them yourself.
Where the structure allows it, tapered polyisocyanurate solves the problem properly by building slope into the assembly instead of hoping the deck provides it. Where the parapet height or the door thresholds will not accept the extra build-up, we add overflow scuppers, enlarge the drain bowls, and specify a membrane that genuinely tolerates standing water rather than one that merely survives it for a while. Saying which of those two you are buying is part of the job.
Membrane choice follows the building. Reinforced TPO in a light color for warehouses and shops where summer heat gain drives the utility bill. EPDM where there is heavy rooftop traffic or a lot of penetrations to detail. Two-ply modified bitumen where the roof takes real abuse or where a torch-free cold application suits an occupied building underneath.
Details are the whole job on a low-slope roof. Curbs raised to a proper height, pitch pans replaced with sealed boots, walkway pads under the condensing units so a technician does not puncture the field, and a termination bar with counterflashing at every parapet rather than sealant at the top edge. We photograph each detail before it is covered.
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 flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing 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 flat & low-slope roofing
Quality here is not a matter of opinion — it is written down.

If a contractor cannot tell you which standard a detail comes from, that is worth asking about before you sign.
