Roofing Services in San Jose, CA
Quartz Construction & Remodeling is a San Jose-based, family-owned contractor (CSLB Lic. #1003436) handling roof installation, repair and inspections. The right material for a Bay Area roof depends on your roof slope, your climate zone and California’s Title 24 energy code, not on marketing claims — the comparison below is meant to help you ask the right questions before choosing.

How do I choose a roofing material in the Bay Area?
Industry Resources & Standards:
Start with your roof's slope and your home's climate zone, since both affect which materials qualify under California's Title 24 energy code when you re-roof. Then weigh fire exposure, HOA or historic-district rules, and how the material performs over time in your specific location.
A roofing contractor can confirm which materials are code-compliant for your address, but the slope/climate-zone/code sequence below is the same for any Bay Area home.
Roofing materials: what each is used for
| Material | Typically used on | Title 24 cool-roof note |
|---|---|---|
| Asphalt shingle | Steep-slope roofs; most common residential choice | Needs a cool-roof-rated product (CRRC-listed) in many climate zones for re-roofs over 50% of the roof area |
| Concrete or clay tile | Steep-slope roofs; common in parts of the Bay Area | Tile's higher mass and reflectance can help meet cool-roof solar reflectance/emittance minimums, but product-specific CRRC rating still applies |
| Metal (standing seam or panel) | Steep or low-slope roofs | Factory finishes are commonly available with CRRC-rated reflective coatings to meet Title 24 |
| Low-slope / flat membrane (TPO, modified bitumen, etc.) | Flat or near-flat roof sections, additions, porches | Cool-roof solar reflectance and thermal emittance minimums apply to low-slope re-roofing in all California climate zones |
This is not a price or lifespan comparison — those depend on the specific product, your roof’s condition and current material pricing, which we quote after an inspection. No cost figures here are implied or estimated without a walkthrough.
Does Title 24 apply when I replace my roof?
Under the California Energy Code (Title 24, Part 6), cool-roof requirements apply to re-roofing projects that replace, recover or recoat more than 50% of the roof area (or 2,000 sq ft, whichever is smaller). The roofing product generally needs to meet minimum aged solar reflectance and thermal emittance values — or an equivalent solar reflectance index — and be listed with the Cool Roof Rating Council (CRRC) to document compliance. Roofs with sufficient thermal mass (gravel, concrete pavers, stone) over the membrane can be exempt from the reflectance/emittance minimums. Source: California Energy Commission, Energy Efficient Cool Roofs (single-family residential) (checked 2026-10-15). Requirements vary by climate zone and your local building department has final say — confirm before choosing a product.
Why it matters: picking a material before confirming it is CRRC-listed for your climate zone can mean reselecting it later during permit review.
How a roof replacement typically runs
Inspection
We assess the existing roof, decking and any trouble spots (flashing, valleys, penetrations) before recommending repair vs. full replacement.
Material selection
We confirm which materials are CRRC-listed and Title 24 compliant for your roof slope and climate zone, then review options with you.
Permit
Most re-roofing in San Jose and surrounding cities requires a building permit; your city's building department confirms exact requirements for your address.
Tear-off and deck check
Old roofing is removed and the deck is inspected for damage before new material goes down.
Installation
Underlayment, flashing and the chosen roofing material are installed to manufacturer and code specifications.
Final inspection
The completed roof is reviewed against the permit and, where applicable, CRRC documentation is kept on file.
Roofing questions
Do I need a permit to replace my roof in San Jose?
Most re-roofing projects require a building permit. Confirm the exact requirement for your address with your city's building department before work starts.
What is a cool roof and when is it required?
A cool roof uses materials with higher solar reflectance and thermal emittance to reduce heat absorption. California's Title 24 energy code requires cool-roof compliance on most re-roofing projects that replace more than half the roof area; some roofs with heavy thermal mass over the membrane are exempt. See the California Energy Commission source above for the current rule.
Can I choose any roofing material I want?
You can choose among materials that are code-compliant for your roof slope, climate zone and any local rules (HOA, historic district, fire zone). We confirm which CRRC-listed products qualify before you commit to one.
Is metal roofing more fire-resistant than shingles?
Material choice is one factor in a roof's fire classification, but the full assembly (underlayment, decking, installation) and your local fire-hazard zone rules also matter. We review your specific requirements during the inspection.
How do I know if I need a repair or a full replacement?
It depends on the extent and location of the damage, the roof's age and condition of the decking underneath. We give you a written assessment after inspecting the roof, not a guess from photos.
How much does a new roof cost?
Cost depends on roof size, slope, material, and what the tear-off reveals about the deck underneath. We provide a written estimate after an on-site inspection. Call (650) 749-7436 to schedule one.
