What Roof Sheathing Repair in San Marino, Texas Covers
Decking is the part of your roof you never see, and it is the part that holds everything else up. Fixing it properly the first time costs less than fixing it twice.
Roof sheathing repair is the work of cutting out water-damaged or delaminated roof decking and replacing it with new plywood or OSB panels nailed to the rafters, then re-covering the area with underlayment and shingles. Sheathing is the structural skin your whole roof sits on. When it softens, nails lose their grip, shingles lift, and water finds a path straight into your attic.
San Marino sits in Bexar County, where summer attic temperatures push past 140 degrees and spring hail pounds roof decks hard. That heat-and-hail cycle dries out plywood, cracks pipe boot seals, and lets water soak the decking around chimneys and valleys. Homeowners searching for roof sheathing replacement near me San Marino Texas usually find us after a ceiling water stain shows up weeks after a storm.
- What it is
- Replacing soft plywood or OSB panels under your shingles.
- When it helps
- Ceiling stains, musty attics, and post-storm leaks.
- What you get

How Our Sheathing Repair Process Works
Every job follows the same five steps, from the first attic walk-through to the final hose test.
Tools and Methods We Use
Each method answers a different question. Together they leave very little to guess.
Shows temperature differences in the attic that reveal hidden moisture behind decking and insulation, even when the surface looks dry to the eye.
Gives us a full view of the roof plane and lets us document damage on steep or hard-to-reach sections without putting a person on every slope.
Traces the path of a leak through the roof system so we repair the source, not just the symptom. Useful on flat and low-slope roofs.
Confirms the repair holds before we close the roof. We run water over the repaired area while someone in the attic watches for drips.

How Sheathing Repair Runs in San Marino
San Marino sits in Bexar County, where the roof decking takes a beating from both ends of the weather. Summer attic temperatures push past 140 degrees, which dries out plywood and cracks pipe boot seals. Spring and early summer bring hail that bruises shingles and dents the decking underneath.
Monte Vista
Older homes with original wood decking and clay tile roofs. Tile sheds water well but hides slow leaks, so we check the decking with a moisture meter before closing any repair.
Stone Oak
Two-story homes with steep shingle roofs and lots of pipe penetrations. Cracked pipe boots are the most common cause of decking rot we see here.
Alamo Ranch
Newer construction where builder-grade underlayment is starting to age out. We see decking damage around chimneys and valleys after the first big hail event.

PhotoChimney Flashing Rot in Monte Vista
Before: A slow leak at the chimney had soaked two plywood panels and the rafter tail over the course of a year. The homeowner had a brown ceiling stain in the living room and had already patched the shingles twice without fixing the source.
After: We rebuilt the step and counter-flashing, replaced both panels with matched 1/2-inch plywood, sistered the rafter tail, and re-covered with new underlayment and shingles. The hose test held, and the ceiling stain stopped spreading within a week.
Hail-Bruised Decking in Stone Oak
Before: A June hail storm cracked two pipe boots and bruised shingles across the back slope. By August the attic smelled musty and the decking around both pipes read above 25 percent on the moisture meter. The homeowner had not noticed any ceiling stain yet.
After: We replaced both pipe boots, cut out three soft OSB panels, and re-decked with new 7/16-inch OSB. New underlayment and matching shingles went down over the repair. The moisture meter read under 12 percent on the final check.
Flat Roof Ponding in Downtown
Before: A clogged roof drain on a low-slope section had ponded water for months. The modified bitumen membrane had failed at a seam, and the plywood decking underneath had delaminated across a 4-by-8 section. The interior ceiling showed a spreading water stain.
After: We cleared the drain, repaired the membrane seam, replaced the delaminated plywood, and re-pitched the drain area so water moves off the roof. The interior stain was treated and sealed after a hose test confirmed the leak was fixed.
Decking Problems We Fix for San Marino Homes
Most of the decking damage we see started as a small leak that nobody noticed until the ceiling stained.
Soft decking around a cracked pipe boot
Water tracks down the pipe and soaks the panel, which then delaminates and stops holding shingle nails.
Chimney flashing failure rotting the decking
Failed counter-flashing lets water run behind the shingles and soak the decking at the chimney.
Hail-bruised shingles hiding soft panels
Hail cracks shingles and pipe boots, and the decking under the impact points dents and softens.
Valley leaks soaking the decking fast
Roof valleys carry the most water on the roof.
Flat roof ponding rotting plywood decking
Ponding water on a flat TPO or modified bitumen roof works its way through seams and saturates the plywood decking below.
Why Fix the Decking First
Shingles are the roof you see. Sheathing is the roof that holds.
Stops Repeat Leaks
Water that soaks into soft decking keeps traveling, so a patch on the shingles rarely holds.
Restores Nail Holding Power
Shingle nails need solid wood to bite into.
Protects Attic and Insulation
A soft panel lets humid attic air and rain drip onto insulation, which then holds moisture against the ceiling drywall.
Prevents Structural Sag
Decking that stays wet long enough rots the rafters under it. Catching it early keeps the repair to panels and flashing instead of framing.

What San Marino Homeowners Say
We had a ceiling stain that kept coming back after two shingle patches. The crew went into the attic with a moisture meter, found three soft panels around the chimney, and replaced them the same week. They showed me the photos of the rotted wood before they covered it up. No leak since, even after the last hail storm.
Hail cracked two pipe boots and I did not notice until the attic smelled musty. They replaced the boots, cut out the decking around both pipes, and re-flashed everything. Took one day. The price matched the written scope exactly and they magnet-swept the driveway before leaving.
We manage four rentals and one had a slow roof leak that had softened the decking over the garage. They gave us a panel count and a price up front, replaced the OSB, and re-shingled to match. Clean work, no callbacks, and they sent photos for our records.
