Signs You Need New Roof Installation
- ▸Shingles are curling, cracking, or missing — once the granule coating wears off, the asphalt layer bakes and becomes brittle, leaving your roof deck exposed to water intrusion
- ▸Granule buildup in your gutters — heavy granule deposits in gutters or at downspout bases means your shingles are nearing end of service life, accelerating heat absorption and UV damage
- ▸Sagging roof decking — a roof deck that dips between rafters signals prolonged moisture damage to the OSB or plywood sheathing, which cannot support a new shingle layer safely
- ▸Flashing failures around penetrations — corroded or pulled-away flashing at chimneys, skylights, and vents causes repeated leaks despite repairs, pointing to systemic failure
- ▸Roof age exceeds 20 years — standard architectural shingles carry a 20-25 year functional lifespan; UV radiation and heat cycles degrade shingles faster in hot climates
A full roof replacement begins with a thorough inspection of your existing roofline. The crew sets up scaffolding and safety harnesses before stripping the old, weathered shingles down to the roof deck. Contractors tear off damaged felt, underlayment, and any rotted OSB or plywood sheathing, hauling all debris to a dumpster for proper disposal.
With the deck exposed, we inspect every inch for soft spots, water damage, and structural issues in the trusses, rafters, and joists. We replace compromised sheathing and fasten new decking with ring-shank nails. Next, we roll ice-and-water shield along the eaves, valleys, and around penetrations, followed by synthetic underlayment across the full roof deck.
Contractors install new drip edge along every eave and rake, then flash all critical areas — step flashing at walls, counter-flashing at the chimney, and pipe boots at every vent penetration. Your new architectural or dimensional shingles are laid with precise overlap, fastened with a nail gun to manufacturer specifications. Ridge cap shingles and ridge vents complete the system, ensuring proper attic ventilation. Every job is inspected against local building codes before we consider it finished.
