Roof Decking Replacement in Irving, TX

Signs of a Rotted Roof Deck You Can Spot Yourself

Roof sheathing is the layer of plywood, OSB or boards between your rafters and the shingles. It fails quietly, but it rarely fails without a few clues. Before we ever quote a roof replacement, we look for these, and you can check several of them on your own:

• Soft or bouncy spots when someone walks the roof
• A wavy roof surface or shingles that ripple instead of lying flat
• A dip along the ridge or between rafters, visible from the street at low sun
• Water rings or black staining on the underside of the deck when you shine a flashlight in the attic
• Daylight through the deck around vents, chimneys or valleys
• Nails that have pushed up and lifted shingle tabs

Any one of these is worth a closer look; two or three together usually mean some sheets will come out at tear-off.

Why Does Roof Decking Fail on Irving Homes?

Irving's housing is old enough for the deck to matter. Point2Homes reports a median build year of 1986, and close to a quarter of local homes date from the 1980s building boom, and many neighborhoods are older than that. Over thirty-plus summers, a deck faces several kinds of stress:

• Slow leaks at cracked pipe boots, worn flashing or shingle splits that soak the same spot every storm
• Attic moisture, when weak ventilation traps humid air that condenses on the cool underside of the sheathing and breaks down OSB strands; our roof ventilation page covers the fix
• Old overlays that held water between layers
• Board decking on mid-century homes, with gaps and split planks that never suited asphalt shingles
• Impacts from fallen limbs during storms

Plywood and OSB Roof Sheathing Replacement: What's Included

Decking work is folded into a re-roof, so it follows a full roof tear-off. On every job, the scope includes:

• Walking and sounding the entire bare deck, not just the spots we suspected
• Marking and photographing every damaged sheet before it is removed
• Cutting out rotted, delaminated or broken sections back to sound framing, and checking rafter tails and fascia edges while they are exposed
• New sheathing of a thickness that suits the rafter spacing, with clips at unsupported edges where needed
• Nailing new and loose existing sheets to the rafters
• Sheathing over board decks where solid decking is required

Panel choice is not one-size-fits-all. We measure rafter spacing before ordering, because a panel that is fine on rafters 16 inches apart can feel springy on 24-inch spacing, and the span rating stamped on each sheet has to match. Plywood and OSB both work when they are rated for the span and fastened on the right schedule; where a roof has a history of attic moisture, we talk through which one tolerates it better on your house.

How Roof Decking Replacement in Irving Works, Step by Step

1. Attic and roof check at the free inspection, so suspected areas are named on the estimate.
2. Tear-off of all shingle layers and felt down to bare wood.
3. Deck walk. Every sheet is checked by foot and by eye, including the edges along eaves and valleys.
4. Show and tell. We photograph each damaged sheet and share the pictures with you before anything is replaced.
5. Cut, replace and re-nail. Damaged sections come out back to the rafters, new sheathing is fastened in, and loose existing sheets are nailed down so the new roof has a flat, solid base.
6. Dry-in. The repaired deck is sealed under drip edge, membrane and underlayment before the crew leaves that day.

What Drives OSB Decking Replacement Cost?

Decking cost depends entirely on what is found, which is why we do not publish a per-sheet number. The variables we explain on every estimate:

• How many sheets fail. A few sheets near a pipe boot is routine; a whole slope under an old leak is not.
• Material and thickness. OSB and plywood differ, and thicker sheathing costs more.
• Board-to-sheet conversion. Laying new sheathing over an entire board deck is a larger scope than spot repairs.
• Framing repairs. Cracked rafters or rotted fascia found under the deck add carpentry.
• Access. Steep slopes and cut-up rooflines take longer to cut and fit.
• Rafter spacing. Wider spacing can call for thicker panels or edge clips across the whole roof, not just the repaired spots.

You see photos of every replaced sheet, so the decking line on your invoice matches what was actually done. One more variable sits outside our control: if a fallen limb or a storm opening caused the damage, the decking may belong to an insurance claim, and your insurer decides what its approved scope covers. In that case we photograph the damaged wood before removal so the record exists either way.

Sagging Roof Repair: When It Is More Than Decking

A sagging roof does not always mean rotted sheathing. A dip between two rafters is often a soft sheet, but a sag running along the ridge or across several rafters can point to cracked rafters, undersized framing or a ridge that has dropped. When the framing is the problem, new decking alone will not straighten it. We tell you what we see, and if it is structural, we recommend having a structural engineer or framing contractor evaluate it before the roof goes back on. Homeowners searching for sagging roof repair around Dallas should start with an attic check, not a shingle quote.

Code, Warranty and Areas We Serve

The International Residential Code calls for asphalt shingles to be fastened to solid sheathing, and Irving's current code is based on the 2024 edition (effective May 1, 2026); the city's building department confirms which rules apply to your permit. Shingle manufacturers also expect a sound, dry deck, so good decking is part of keeping their material warranty valid. Our own workmanship guarantee is set out in writing in your contract.

Permits for sheathing work in Irving

Decking replaced as part of a re-roof falls under the re-roof permit. A small leak repair is different: Irving's handout on residential roofs lets a repair up to 100 square feet go without a permit, which covers a couple of sheets but not a slope. The state of Texas issues no roofer license, so check that any contractor touching your deck holds a current City of Irving contractor registration, and call the Inspections Department at (972) 721-2371 with questions about your permit.
