New Construction in San Jose, CA

New Construction in San Jose, CA

New construction roofing in San Jose means one thing: putting a roof on a home that’s never had one before. Whether you’re building a custom house in Willow Glen, adding an ADU in Almaden Valley, or framing a second story in Cambrian, the decisions you make now affect the building for the next 30 to 50 years. Tilehurst Roofing San Jose handles new-construction roofing from the sheathing up, and every job starts with a written price before any work starts. If you’re planning a build and want to talk through materials, code requirements, and realistic timelines, call us at (669) 274-0078. For a broader look at how this fits into a full project scope, see our Roof Replacement & Installation page.

New construction is not the same thing as a re-roof. On a re-roof, we’re tearing off old material and often discovering what’s underneath. On new construction, we’re working from bare plywood or OSB sheathing with a clean slate. That sounds simpler, and in some ways it is. But it also means every layer matters from the first day, because nothing gets to hide behind an existing roof. We install the underlayment, the flashing, the drip edge, the ridge cap, and the shingles or tile as one continuous system. No shortcuts, no “good enough for now.” This is the roof your family will live under for decades.

Greg Holloway leads every Tilehurst Roofing San Jose job with a simple expectation: show up, tell the truth, put it in writing. That’s the home base of how we operate, and it matters even more on new construction, where general contractors and owners are already juggling a dozen moving parts. You don’t need a roofer who adds drama. You need one who arrives, installs, documents, and moves on.

When You Need New Construction

If any of the following describe your project, this is the page you’re looking for:

• You’re building a new home from the ground up. A new single-family house in San Jose needs a roof that clears city inspection the first time and performs for decades. This is the most common scenario we handle.
• You’re adding an ADU or garage conversion. Accessory dwelling units are everywhere in San Jose right now, from Evergreen to Berryessa. The roof on an ADU needs to tie into the existing structure correctly, especially where the new roof meets the house wall.
• You’re doing a full second-story addition. When you frame up and the old roof comes off, the new upper roof is a new construction job. The tie-in at the old eave line matters, and so does matching the material profile if the lower roof is staying.
• You’re replacing structural roof framing after damage. If a tree took out rafters in the Santa Cruz Mountains-adjacent hillsides, or an older San Jose home has termite damage in the roof structure, you may be rebuilding the roof assembly rather than re-roofing over it.
• You’re building a covered patio, breezeway, or detached structure. New construction doesn’t have to be a house. Any new roof plane over livable or semi-livable space needs the same underlayment, flashing, and ventilation treatment.
• A previous roofer walked off the job. It happens more often than you’d think. We get calls from San Jose homeowners whose GC is stuck because a roofing sub never showed. We finish new-construction roofs that someone else started and abandoned.

One thing to know about San Jose specifically: the city and Santa Clara County both enforce Title 24 energy requirements that affect roof design, including cool-roof standards for low-slope applications in many cases. We factor that in during the estimate, not after the fact. If you’re in a high-fire-risk zone in the eastern foothills east of Alum Rock or in parts of the hills near the Calero Reservoir, the material choice may need to satisfy Chapter 7A wildfire-resistant construction requirements. We’ll walk you through it in plain language.

Our New Construction Process

Here’s how it goes when you hire Tilehurst Roofing San Jose for new construction:

1. Walkthrough and measure. We come out to the site, walk the framing, and take exact measurements. We look at the pitch, the venting plan, the decking, and the surrounding structures. If there’s an open question about code, we flag it that same day.
2. Written price. Before any work starts, you get a written estimate that covers materials, labor, waste removal, and any known permit or code-related extras. The price doesn’t change because we learned something at the door. If we discover a real issue during install, we always discuss it before doing anything outside the written scope.
3. Material selection. You choose from seven major manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. We stock samples and can order any line from any of those seven. We’ll give a direct recommendation for your specific San Jose exposure, whether that’s the heat on a west-facing slope in Willow Glen or moisture concerns in a shaded Alviso lot.
4. Installation. Our background-checked, uniformed crew arrives at the scheduled time. We install deck protection first, then underlayment, then flashing at every penetration and transition, then the roof covering, then ridge and edge details. We leave the job site cleaner than we found it, every day, not just on the last day.
5. Final walkthrough and written guarantee. Greg Holloway himself does the final inspection with you before the crew leaves. You get the written guarantee in your hand that day, not mailed a week later. Every single new construction roof carries the 365-Day Done Right Promise, which means if anything’s not done right in the first full year, we come back and fix it.

That promise isn’t a marketing line. It’s the reason we put it in writing on every job: the Kingswell Way is to say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, and come back if it fails.

New Construction Pricing in San Jose

Here’s the honest answer on what new construction roofing costs in San Jose. For a standard asphalt-shingle new roof on a single-story, 1,500-square-foot home, you’re generally looking at $12,000 to $19,000 for a full system installed correctly. For a two-story home of similar square footage, that range climbs to $15,000 to $24,000 because of working height, safety setups, and often steeper or more complicated planes. These numbers assume standard architectural asphalt shingles, new underlayment, new drip edge, new flashing, and standard ridge cap.

Here’s a breakdown by material class for a typical 1,500-square-foot new construction roof in San Jose:

• Asphalt architectural shingles (GAF, Owens Corning, Atlas): $12,000 – $19,000. Most popular by far. Good balance of cost and lifespan, typically 25 – 30 years.
• Upgraded asphalt lines (CertainTeed, prestige GAF lines): $15,000 – $23,000. Better wind ratings, better color depth, often better warranty terms.
• Concrete tile (Boral or Eagle lines): $28,000 – $45,000. Common in newer San Jose Mediterranean and Spanish-style construction. Very long lifespan, but the roof structure must be sized for the weight.
• Standing seam metal roof: $25,000 – $42,000. Less common in San Jose new construction, but great for modern designs and fire-prone zones.
• Composite or synthetic slate (Tamko, certain CertainTeed lines): $22,000 – $36,000. Good middle ground for durability without the weight of clay or concrete tile.

What moves the price up or down? The pitch of the roof is the biggest one. A 4/12 roof is straightforward. A 7/12 or steeper roof means different safety equipment, slower work, and more material. The number of penetrations matters too: every plumbing vent, skylight, and chimney flashing is a detail that takes time. The decking condition matters less on new construction than on re-roofs, assuming the framer used clean, dry lumber. And city of San Jose permit fees are a real line item. We include all of it in the written price, so there’s no surprise at the end.

We don’t do rough bid ranges over the phone and then hope for the best. We walk the site, measure, and hand you a written number. Call (669) 274-0078 and we’ll set a time that works for your build schedule. The estimate is free.

Materials We Use on New Construction

A new construction roof is a one-time chance to get the material exactly right. You’re not constrained by what the old roof looked like. If the house design calls for a cool, white, low-slope membrane, we can do that. If the exterior deserves a deep charcoal architectural shingle with a matching metal ridge, we can do that too.

We work across seven major manufacturers, so the product spec comes from the home’s design and climate needs, not from whatever happens to be in the warehouse. GAF and Atlas both make excellent architectural shingles that perform especially well in San Jose’s hot summer conditions. Tamko makes a strong mid-tier line that a lot of homeowners choose for addition and ADU projects. Boral is the go-to when the home’s design calls for clay or concrete tile, whether that’s a Spanish-style estate in Almaden or a new build in the hills with fire-resistance needs.

We never push a single brand. We’ll explain the differences in warranty structure, granule adhesion, wind rating, and color availability, then let you decide. That’s the point of having options.

Why New Construction Roofing in San Jose Is Different

San Jose has its own roofing season. The wet months from November through March compress the building schedule, and everyone wants their roof dried in before the first real storm. We’ve worked through plenty of those winters, and we know what it takes to get a new construction roof watertight fast without cutting corners on underlayment or flashing. One common call we get in October and November: a homeowner or GC needs a roof on a new addition before the weather turns. We’re answering the phone 24/7, including evenings and weekends, so when that panic call comes, a live person picks up. That’s not a perk. That’s the whole point.

If you’ve been burned before by a roofer who no-showed on a new build, you know how expensive that is. A framer waiting a week for roofers means the whole project slides. The framing lumber sits in the San Jose winter rain because the roof wasn’t installed. That’s why our process is built around showing up when we say we will. Greg Holloway has led Tilehurst Roofing San Jose with that one non-negotiable rule: the appointment window is sacred. If we can’t make it, you’ll know why before the window closes, not after.

We’re a member of the Kingswell family of roofing companies, founded in 2000. Each local Tilehurst office is independently owned and operated, and each one operates under the same written Kingswell Guarantee. That means the promise travels with the work, no matter where you are in the Bay Area. It also means there’s always a structure behind us. We’re not a guy with a truck and a magnet sign. We’re a team with a name on the door and a guarantee in writing.

Common Questions From San Jose Homeowners and Builders

Does new construction roofing cost more than a re-roof in San Jose?

Not necessarily. A new construction roof sometimes costs less than a re-roof because there’s no old material to tear off, no dump fees, and no surprises under the old shingles. But if the new roof has a complex shape, a steep pitch, or specialty materials like clay tile from Boral or a standing seam metal profile, the cost can equal or exceed a typical re-roof. The only way to know your real number is to get a written estimate after we measure. Call (669) 274-0078 and we’ll schedule it free.

How long does new construction roofing take in San Jose?

A standard single-story asphalt shingle roof over new framing takes most of our crews 3 to 5 working days, including underlayment, flashing, shingles, and ridge cap. A two-story home or a tile roof takes longer, typically 7 to 12 working days. Weather is the wildcard in San Jose winters. We’ll give you a realistic window when we write the estimate, and we’ll keep you posted by phone if anything shifts.

What’s the best roofing material for new construction in a fire zone in San Jose?

In a wildfire-risk area, the best choice is generally a Class A fire-rated material like metal, concrete tile, or a Class A asphalt shingle system. Boral makes concrete tile lines that are commonly specified in higher-risk hillside areas, and standing seam metal from our manufacturer network is another strong option. We’ll look at your address, the local hazard designation, and the design of the house, then give you a direct recommendation that satisfies Chapter 7A where it applies. Call (669) 274-0078 to talk it through.

Do you work with general contractors, or only directly with homeowners?

Both. Many of our San Jose new construction jobs are done in coordination with a general contractor or a design-build firm, and we welcome that. We also work directly with homeowners who are acting as their own GC on an ADU, an addition, or a custom new build. Whichever setup you have, the written price is in your hands before any work starts, and the written guarantee goes to the property owner, not just to the contractor.

Can you handle the roofing for an ADU in San Jose at the same time as the main house roof?

Yes. If you’re building a new main residence and a detached ADU at the same time, we can sequence the roofing so both structures are weathertight as early as possible. That’s especially helpful in San Jose’s rainy season. We’ll put both the main house and the ADU on the same written estimate, with line items for each structure so you can see exactly where the money is going.
