What Our Roof Deck Repair Includes
Every deck repair we do covers the structural fix and the roof components that have to come up with it.
Work order
Roof Deck Repair- Full Moisture Inspection: We check the deck from the attic side with a moisture meter and from the roof side with an infrared thermal imaging camera. You get photos of every wet or rotted area before we quote the repair.
- Rotted Sheathing Removal: We cut out the soft decking back to sound wood and mark the extent on the framing. Old sheathing goes in the trailer, not on your lawn. Most single-area removals take two to three hours.
- New Decking Installation: We install new sheathing matched to your existing thickness and span, then nail it to manufacturer spec. If the rafters need sistering, we do that before the new deck goes down.
- Underlayment and Flashing Check: New roof underlayment goes over the repaired deck. We inspect pipe boots, roof flashing, and valley sections while they are exposed and replace anything that has failed.
- Water Test Before We Leave: We run a hose test over the repaired area and watch it from the attic side. If anything weeps, we find it now. Then we magnet-sweep the yard and walk the job with you.

What Roof Deck Repair in San Marino, Texas Involves
A roof deck is what holds your covering down and keeps water out of the building. Repairing it properly is what makes the fix last. Patching over soft wood just moves the problem to next season.
Roof Deck Repair in San Marino, Texas is the structural fix underneath the roof covering, not a patch on top of it. When water gets past shingles, flashing, or a cracked pipe boot, it soaks the roof underlayment and the wood sheathing below. That wood softens, delaminates, and loses the grip that holds nails. We cut out the bad sections, sister in new framing where needed, and re-sheet the deck with material matched to your existing thickness and span.
Most San Marino homes we open up have the same story: a slow leak that ran for months before anyone noticed. Attic water intrusion shows up as dark staining on the rafters, a musty smell, or insulation that sags. Left alone, rotted decking spreads, and a small repair turns into a full re-sheet. That is why we push roof decking repair San Marino homeowners can schedule early, before the next storm season tests a deck that is already weak.

How Our Roof Deck Repair Process Works
From the first call to the final walk-around, here is what you can expect when we handle your deck repair.
Tools and Methods We Use on Deck Repairs

How Deck Repair Runs in San Marino
San Marino sits in the middle of Texas hail and wind country, and that shapes almost every deck repair we do here. Hail bruises shingles and cracks tile, and the deck below takes on water long before the damage shows inside.
Monte Vista
Older homes here often have original wood decking under clay tile. Tile hides deck rot well, so we probe carefully around valleys and chimneys.
Beacon Hill
Many roofs in this neighborhood have been re-covered multiple times. We check for layered shingles and decking that has been patched before.
Stone Oak
Newer builds use OSB sheathing that swells fast when it gets wet. Catching leaks early keeps the deck from delaminating.

PhotoChimney Flashing Leak, Monte Vista
Before: A slow chimney flashing leak had soaked about 40 square feet of decking around the chimney. The homeowner had patched the shingles twice, and the ceiling stain kept coming back after every rain. The sheathing was soft enough that a screwdriver sank in with light pressure.
After: We cut out the rotted sheathing, sistered one rafter, and installed new decking and underlayment. New counterflashing and sealant closed the leak path. The hose test ran clean, and the ceiling stain stopped growing after the next storm.
Valley Leak and Rotted Sheathing, Beacon Hill
Before: A valley leak on a 1940s bungalow had rotted roughly 60 square feet of original 1x6 decking. The homeowner noticed a musty smell in the attic and sagging insulation. The valley metal had rusted through in two spots.
After: We replaced the decking, installed new valley metal, and re-covered the area with matching architectural shingles. The attic dried out over the following week, and the musty smell cleared. No leaks after two heavy rain events.
Hail-Damaged Deck Under Tile, Stone Oak
Before: A June hail storm cracked several concrete tiles and drove water into the deck below. About 30 square feet of OSB sheathing had swelled and delaminated. The homeowner saw a brown ring on the ceiling in the hallway.
After: We replaced the swollen sheathing, matched new tiles to the existing profile, and re-flashed the area around the damaged section. The ceiling ring stopped spreading, and the deck passed a hose test before we left.
Deck Problems We Fix Before They Spread
Most deck damage starts small and stays hidden until it is expensive.
Soft spots under the shingles
Soft decking means the nails holding your shingles have lost their grip.
Ceiling water stains that keep coming back
A stain that returns after a shingle patch means water is still reaching the deck.
Attic water intrusion after storms
Water in the attic soaks insulation, which stops insulating and starts growing mold. The deck above stays wet, and rot spreads across the sheathing between storms.
Flashing failure at chimneys and skylights
Chimney flashing leaks and skylight flashing leaks send water straight to the deck at the curb.
Why Fix the Deck, Not Just the Shingle
A shingle patch over soft wood buys you a season, maybe two. Fixing the deck underneath is what makes the repair last.
Nails That Actually Hold
Shingle and tile fasteners need solid wood to bite into.
Stops the Leak at the Source
Water that reaches the deck will keep finding a path down, no matter how much sealant you smear on top.
Protects the Framing Below
Rotted sheathing passes moisture to rafters, trusses, and eventually the top plate of your walls.
Keeps Your Warranty Valid
GAF, Owens Corning, and CertainTeed all expect the deck to meet nailing requirements before their material goes down.

What Neighbors Say About Our Deck Work
We had a ceiling stain that kept coming back after two shingle patches. These guys opened the roof and found about 40 square feet of rotted decking around the chimney. They showed me photos before they cut, replaced the sheathing, and re-flashed the chimney. No leak since, and that was after two heavy rains.
Our 1940s house had original decking under the shingles, and part of it was soft near the valley. They sistered two rafters and replaced the sheathing in one day. Price came in right where the estimate said. They swept the yard for nails twice before they left.
We manage a small commercial building with a flat roof, and a seam leak had soaked the deck under the TPO. They repaired the deck, re-seamed the membrane, and tested it with a hose before they packed up. Scheduled around our tenants, no disruption. Good communication the whole way.

2109395773Small repairs under 32 square feet sit at the low end. If the damage spans multiple areas or the covering has to come up across a full slope, expect the higher end. You get a written price before we start.
Yes. We replace roof decks across San Marino and the surrounding San Antonio neighborhoods, usually within three to five days of your estimate. A single-area replacement takes one day. If the job covers a full roof slope or includes new underlayment and flashing, plan on two to three days. We confirm the schedule in writing when you book.
A typical deck replacement takes one to three days of on-site work. Tear-off and deck removal for a single area runs two to three hours. Installing new sheathing, underlayment, and re-covering the exposed section adds the rest. Full-slope replacements with new flashing and pipe boots can stretch to three days. Weather delays are the only thing that pushes it longer.
Rotted decking is the main thing we repair. We cut out the soft sheathing, probe the rafters for rot, and sister in new framing where the structure has lost strength. We use a moisture meter and infrared thermal imaging camera to find wet wood that looks fine on the surface. If the rot has spread to the framing, we tell you before we quote the fix.
