Residential & Commercial Roofing in Alleghany
From quick fixes to major projects, Alleghany Roofing & Maintenance has been the roofing contractor Alleghany homeowners call for 23 years. Here's a rundown of what we offer.
Roof Replacement
Full roof replacement starts with a complete tear-off down to the deck. We inspect every board for rot or soft spots. In Alleghany, we find decking damage on about 30% of tear-offs. Damaged sections get replaced with CDX plywood before anything else goes on. Then we build up: ice and water shield in valleys and at eaves, synthetic underlayment across the full deck, new drip edge on every edge, starter strip, field shingles, hip and ridge caps, and ridge vent. Dumpster, permits, and cleanup included.

Roof Repair
We repair asphalt shingle, metal, flat membrane, and tile roofs. Our trucks carry common repair materials so most fixes happen same-visit. Shingle repairs, flashing replacement, pipe boot swaps, ridge cap fixes, valley re-flashing. All routine for our Alleghany crews.

Storm Damage Repair
Not all storm damage qualifies for a full replacement. Hail might only damage one slope. Wind might only lift shingles on the windward side. We document exactly what's damaged and let the insurance company make the call. Honest documentation gets claims approved. Inflated claims get denied.

Metal Roofing
Corrugated metal and R-panel (exposed fastener) at $5-$8/sq ft installed for agricultural buildings, shops, carports, and covered patios in Alleghany. 29-gauge is budget, 26-gauge is standard. For residential, we recommend 24-gauge standing seam at $12-$22/sq ft. The aesthetics and longevity justify the premium. DaVinci composite shake and slate profiles offer the look of natural materials with metal's performance. Perfect for Alleghany HOA neighborhoods that restrict metal roofing appearance.

Shingle Roofing
Shingle color matters more than you think. Dark shingles absorb heat. Great for cold California winters, harder on cooling bills in summer. Lighter colors reflect heat. Algae-resistant granules prevent black streaking. We bring shingle samples to your Alleghany home so you can see them against your siding and trim.

Flat Roofing
Flat roofs don't actually drain themselves. That's the challenge. Water ponds, UV breaks down the membrane, and eventually it leaks. We install and repair TPO, PVC, EPDM, modified bitumen, and built-up roofing systems designed for zero-slope conditions in Alleghany.

Commercial Roofing
For commercial kitchens and restaurants in Alleghany, PVC membrane is the only option that resists animal fat and chemical exposure from rooftop grease exhaust. We install IB Roof Systems and Duro-Last PVC with heat-welded seams and custom accessories. Modified bitumen with SBS or APP polymer-modified asphalt for high-traffic commercial roofs. Two-ply systems with 20-year NDL (No Dollar Limit) warranties from Johns Manville or Firestone.

Gutter Installation
We custom-form seamless aluminum gutters on-site from a continuous coil of .027 gauge stock. No factory seams means no seam failures. We form them to the exact length your fascia requires. One piece, one gutter, no leaks.

Roof Inspection
Commercial and flat roof inspections include infrared moisture scanning with Flir E8 thermal cameras. Trapped moisture in the insulation layer shows as temperature differentials on the thermal image. No need to cut core samples everywhere. We identify wet zones, then core sample the suspect areas to confirm. This approach gives you a precise repair scope at a fraction of the cost of exploratory tear-offs.

Emergency Roof Repair
Our trucks carry 20x30 reinforced tarps, 2x4 lumber, plywood sheets, pipe boots, ridge cap shingles, flashing stock, roofing cement, and neoprene screws. We show up ready to secure your roof, not ready to schedule a follow-up appointment.

Skylight Installation
VELUX FS (fixed) and VS (vented) skylights installed with EDL flashing kits for shingle roofs. The multi-step flashing integrates with the surrounding shingle courses per IRC R903.2. We frame the curb with doubled 2x8 or 2x10 lumber (depending on rafter depth), install ice and water shield membrane around the entire curb perimeter, then set the skylight with factory sealant before weaving step flashing into the field. Top headwall flashing tucks under the upslope shingle course. Bottom sill pan diverts water onto the downslope shingles. Zero exposed sealant joints. Mechanical flashing only.
