Core Installation & Replacement Capabilities

Roof Framing

Stick-framing custom hip, valley, and gable roof architectures using #2 Southern Yellow Pine lumber engineered to carry severe wind, rain, and live dead-loads.

Roof Truss Repair

Fixing cracked top or bottom truss chords, snapped webs, and displaced gang-nail connector plates using PE-engineered plywood gussets and structural lag screws.

Roof Decking Replacement

Tearing out water-delaminated, spongy, or sagged sheathing down to rafters and installing premium 1/2-inch or 5/8-inch 4-ply exterior-rated CDX plywood.

Rafter Repair & Sistering

Sistering cracked or split 2x6/2x8 rafters with full-length dimensionally matched framing lumber bolted with structural TimberLOK fasteners.

Roof Structural Reinforcement

Installing collar ties, purlin braces, and rafter ties to prevent outward wall push and reinforce roof systems when upgrading to heavy slate or concrete tile.

Roof Ridge Beam Repair

Hydraulically jacking sagging roof peak lines back to level laser-straight alignment, sistering ridge boards, and installing heavy vertical post supports.

Our 6-Step Structural Roof Carpentry Protocol

  1. Step 1 — Laser Level Audit & Attic Framing Diagnostic: We perform an extensive attic structural survey using precision optical laser levels, electronic wood moisture meters, and load-path audits to identify broken trusses.
  2. Step 2 — Temporary Heavy-Duty Hydraulic Shoring & Jacking: Before cutting or sistering load-bearing timbers, our carpenters erect temporary shoring posts with hydraulic screw jacks to relieve dead load weight.
  3. Step 3 — Framing Sistering & Simpson Strong-Tie Hardware: Damaged rafters are flanked with full-length dimensionally matched framing members, glued with polyurethane adhesives, and secured with Simpson hurricane anchors.
  4. Step 4 — Rotten Wood Excavation & Truss Gusset Reinforcement: All moisture-softened wood is excised. Cracked engineered truss chords receive dual-sided exterior plywood or 14-gauge steel gusset plates engineered to code.
  5. Step 5 — Exterior CDX Plywood Re-Sheathing & H-Clip Placement: Sub-decking is replaced with minimum 1/2-inch or 5/8-inch 4-ply CDX exterior plywood, secured with galvanized ring-shank nails every 6 inches and steel H-clips.
  6. Step 6 — Deck Planarity & Deflection Quality Verification: We conduct a stringent straight-edge planarity test across all roof slopes and valleys to ensure an ultra-flat foundation before underlayment is rolled out.

Frequently Asked Questions

1. Why is my roof sagging in the middle or dipping along the ridge in Cary, NC?

Roof sagging typically results from water-saturated plywood decking delaminating, undersized rafters spanning too wide, or severe dead-load stress bowing ridge beams.

2. What is the difference between CDX Plywood and OSB for roof decking?

CDX plywood consists of cross-laminated sheets of real wood veneer bonded with exterior glue. It holds nails 30% tighter and dries quickly without swelling compared to OSB.

3. What is rafter sistering and when can a damaged rafter be repaired without tearing off the roof?

Rafter sistering positions a new full-length piece of lumber alongside a damaged rafter, bonded with structural adhesive and bolts to transfer roof loads safely.

4. Can broken engineered roof trusses be repaired legally in North Carolina?

Yes, but NC building codes require a certified engineering repair plan. Our team works with licensed NC structural engineers to install PE-stamped gusset plates.

5. How do roofers know if plywood decking is rotted before stripping off shingles?

Experienced roofers detect rotted sheathing through spongy spots underfoot, attic underside moisture inspections, and optical surface dips.

6. What is the cost of replacing rotted plywood decking sheets during a roof replacement in Cary?

Replacing rotted decking in Cary typically costs between $65 and $95 per 4ft x 8ft sheet of CDX exterior plywood, including tear-out, disposal, and ring-shank nailing.

7. What causes roof wood rot in Wake County attics even if shingles don't have holes?

Poor attic ventilation is the #1 cause: warm rising indoor moisture condenses on the cold underside of decking, causing fungal dry rot over time.

8. How do structural reinforcements allow older Cary homes to support heavy tile or slate?

Our carpenters sister rafters with engineered LVL timbers, install heavy horizontal collar ties to prevent wall spread, and add vertical purlin struts.
