Roof Replacement in Northern California

A full roof replacement is fundamentally different from a patch repair. You're not working around an existing system — you're building from the deck up. That means decisions made at install time (underlayment selection, flashing details, ventilation design, material choice) determine whether your roof lasts 25 years or 50.

KTN Roofing specializes in new construction roofing and major renovation projects across Placer County and the Sierra Nevada foothills. We work directly with homeowners, general contractors, and architects to deliver roofing systems designed for the specific climate, structure, and aesthetic goals of each home. Owner Fernando Banuelos personally oversees every roof replacement job from initial spec to final inspection.

The right material depends on your home's structure, location, and how long you plan to own it. Asphalt composition shingles remain the most popular choice — modern architectural shingles offer 30-50 year warranties, excellent UV resistance for Northern California's intense sun, and a wide variety of styles and colors. For foothill properties (Auburn, Newcastle, Grass Valley), Class A fire-rated systems are mandatory and we install accordingly.

Concrete and clay tile systems suit Mediterranean and Spanish-style architecture and can last 40-50 years. Metal roofing is the longest-lasting option, ideal for fire-prone areas and homeowners who want a one-and-done install.

We help homeowners and builders evaluate these options against budget, structural capacity, neighborhood architecture, and resale considerations. There's no single "best" material — there's the right material for your specific home.

KTN handles both. For new construction homes, we work from the architect's specifications or help you select the right system if specs are still open. We coordinate with framers and other trades to integrate roof venting, plumbing penetrations, electrical, and skylights cleanly.

For major renovations — additions, second-story expansions, full home remodels — we evaluate how the new roof will tie into existing structure, match (or intentionally contrast) the existing roof, and meet current California building code requirements. Renovations often require permits and inspections that we handle on your behalf.

A roof replacement starts with a detailed planning conversation: what's the project scope, what's the timeline, what materials are you considering, what's the budget. We review architectural plans (for new builds) or assess the existing structure (for renovations) and provide a written estimate within 2-3 business days.

Installation follows a defined sequence: roof deck inspection and prep, synthetic underlayment installation (rated for the region's heat and UV), proper flashing installation at all penetrations, ventilation system installation, primary roofing material installation per manufacturer specs, and final detail work (ridge caps, drip edges, gutter integration).

We pull permits, schedule inspections, and coordinate with other trades on multi-phase projects.

Northern California's foothills carry elevated wildfire risk, and many municipalities in our service area (Auburn, Grass Valley, parts of Newcastle and Granite Bay) require Class A fire-rated roofing systems on new construction. KTN installs these systems regularly and is familiar with the additional requirements: non-combustible underlayment, ember-resistant ventilation, metal flashing details, and specific roof-to-wall transitions.

We help homeowners navigate these requirements and design roofing systems that meet code while still achieving the aesthetic and budget goals of the project.
