You've been told you need a new roof. Maybe the inspector flagged it during a home sale, the insurance company won't renew, or the leaks keep coming back faster than you can patch them. A new roof isn't a decision to rush — but it isn't one to delay either. We install GAF and Owens Corning roofing systems to manufacturer specs, give you a written estimate before any work starts, and protect your home from the first tarp to the final cleanup.
Signs You Need a New Roof (Not Another Repair)
Asphalt roofs past 18–20 years are on borrowed time. Multiple leaks in different parts of the roof, widespread granule loss in your gutters, and curling, cupping, or blistered shingles across large sections are signs the system is failing as a whole. A sagging roofline needs a structural look. Decking that feels soft when walked usually means moisture has been there a while. Previous repairs that didn't hold, an insurance non-renewal letter, or a sale contingency flagging the roof — those are all clear signals.
Spot repairs make sense up to about 25–30% of the roof. Past that, you're spending good money on a system that's failing as a whole. A new roof installed by certified installers usually adds resale value above the install cost — especially when the extended manufacturer warranty paperwork is transferable to the buyer.
Our Roof Installation Process
It starts with a free on-site estimate. We measure, photograph, climb the roof, and check the attic, then email a written, itemized quote with material options — 3-tab versus architectural asphalt, composite, and Class A fire-rated systems for WUI zones. Then we walk you through the product conversation: the real difference between GAF and Owens Corning warranty programs, the upgrades that matter (synthetic underlayment, ice-and-water shield where appropriate, ridge venting, drip edge), and the ones that don't.
On install day, we tear off down to the deck, inspect and replace any rotted decking, lay underlayment, replace all flashing (this matters more than the shingles), install shingles to the manufacturer's pattern, finish ridge venting, and run a magnetic sweep of the property for nails. Property protection is part of every job: tarps on landscaping, plywood on AC units, daily cleanup. Most residential installs take 1–3 days. We pair every install with a free roof inspection of related systems — and we'll recommend a balanced attic venting system when the existing one won't support manufacturer warranty requirements.
Roof Installation for Hollister and the Central Coast
WUI fire zones in San Benito and Monterey County require Class A fire-rated roofing — and your insurance will increasingly require it on renewal. Salt air in coastal Monterey, Pacific Grove, Carmel, Marina, Seaside, Watsonville, and Aptos demands corrosion-resistant fasteners and flashings. We use coated or stainless hardware on coastal jobs because standard galvanized rusts out fast. Inland, intense Central Coast UV in Hollister, Salinas, Los Banos, and Gilroy degrades cheap underlayment quickly, so we use synthetic on every install.
Atmospheric river rainfall and winter wind require the right nailing pattern and ridge ventilation that meet manufacturer spec — get that wrong and your warranty is void no matter what shingle you bought. A local crew knows that a Pacific Grove install and a Hollister inland install are different jobs, with different materials and different details.
What to Expect
Free on-site estimate booked same-day or next-day. Written, itemized quote within 24–48 hours of the visit. Project scheduled on your timeline — most installs start within 2–4 weeks. We pull permits where required, coordinate with HOAs if needed, and protect your property the entire job. You'll know the final price before we order materials. The job ends with a workmanship warranty plus the manufacturer's extended material warranty registered in your name.
