Fast, Reliable Roof Installation Across San Ramon
A full roof installation in San Ramon typically runs $14,000 to $38,000 depending on square footage, pitch, material, and whether the decking underneath needs replacement. Most tear-off and re-roof jobs on San Ramon’s hillside homes take five to nine working days once permits clear. We’re Crestview Roofing, led by Dylan Pace, and we schedule San Ramon jobs with a written price before any work starts, a named crew, and photo documentation at every step. Call (325) 246-5075 to get your roof scoped by someone who knows the difference between a ridge off Bollinger Canyon Road and a cul-de-sac near Central Park.
Why Crestview Roofing Is San Ramon’s Preferred Roof Installation Company
San Ramon homeowners call us because we write down exactly what we’ll do and what it costs before the first shingle comes off. That’s not a marketing line. It’s the Relay Visibility Guarantee, and it applies to every job we run in San Ramon: a written price up front, before-and-after photos, a live trackable arrival time, and a digital invoice sent by text. Dylan Pace built Crestview Roofing in 2000 on the idea that a roofer should show you what’s happening on your roof, not just tell you it’s fine.
Our San Ramon customers get the same treatment whether they’re off Alcosta Boulevard in the Windemere area or up in the hills near Crow Canyon Country Club. We install manufacturer-backed materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Every repair we make is covered by our 365-Day Done Right Promise: if a covered repair fails within a year, we come back and fix it at no charge. No negotiation. No fine print.
San Ramon’s housing stock runs from 1970s ranchers in San Ramon Village to newer Toll Brothers hillside builds in Gale Ranch. That range matters. A roof spec that works on a flat, sheltered lot near Dougherty Valley High School won’t hold up on a west-facing ridge that takes full afternoon sun and steady wind off the hills. We’ve worked enough roofs in this city to know the difference, and we price accordingly.

Tile Roof in San Ramon
Tile Roof work in San Ramon usually means either a full tear-off and re-tile or a selective re-lay over repaired underlayment, and it’s the most common install we do in the hillside neighborhoods. Concrete tile is everywhere in San Ramon, from the gated communities near The Bridges Golf Club to the older custom homes above Norris Canyon Road. The tile itself often looks fine after 30 years. What fails underneath is the felt and the decking, especially on ridges with heavy sun exposure. A full tile roof installation in San Ramon typically runs $22,000 to $45,000 depending on the number of valleys, penetrations, and whether we’re reusing existing tile or laying new.
Underlayment and Decking Scope
When we bid a tile roof in San Ramon, we inspect the decking before we quote, not after. On west-facing ridges above Bollinger Canyon Road, the original felt is often dried out and the plywood near the ridge is soft from decades of heat cycling. If the sheathing is compromised, we replace it. Skipping this step is how a $18,000 quote becomes a $30,000 surprise mid-job.
Re-Set vs. New Tile
Some San Ramon homeowners want to reuse their existing concrete tile to save on material cost. That’s viable if the tile is intact and the profile is still available for replacements. We’ll tell you straight: if more than 15% of your tile is cracked or spalled, you’re better off with new tile from Boral or another manufacturer we stock. Reusing compromised tile puts your new underlayment at risk.
Roof Ventilation in San Ramon
Roof Ventilation in San Ramon is not an add-on. In the valley neighborhoods near San Ramon Central Park, attic temperatures climb past 130°F in summer, and without balanced intake and exhaust ventilation, your new roof traps that heat against the underside of the decking. That shortens shingle life, cooks the underlayment, and pushes your AC bill up. A proper ventilation package, ridge vent plus soffit intake, typically adds $2,500 to $5,500 to a San Ramon roof installation depending on linear feet and whether we need to cut new intake vents.
Ridge Vent vs. Static Vents
On two-story hillside plans in San Ramon with complex rooflines, a continuous ridge vent often outperforms box vents because it exhausts heat evenly along the entire peak. We see a lot of roofs where the original builder installed too few static vents and the attic never breathes. The fix is sizing the exhaust to the attic volume, not guessing.
Valley Home Ventilation Sizing
A single-story rancher near San Ramon Valley Boulevard has a different ventilation requirement than a three-story Gale Ranch build with a hot attic. We calculate the square footage of attic space and match intake to exhaust one-to-one. Undersizing ventilation on a valley home means the new roof performs no better than the old one, which defeats the purpose of a full install.
Trusted Brands We Service in San Ramon
We install and repair Roof Installation systems using manufacturer-backed materials from GAF, Atlas, Tamko, Boral, and more. For San Ramon tile roofs, we regularly work with Boral concrete and clay tile profiles. For architectural shingle installs, we recommend Atlas Pinnacle or GAF Timberline depending on the exposure and wind rating required. We keep common flashing, underlayment, and ventilation components stocked for fast turnaround on San Ramon jobs, which means fewer delays waiting on material runs from warehouse suppliers. When your roof is torn off and rain is in the forecast, that stock matters.
Common Roof Installation Problems We See in San Ramon Homes
- Skipped decking inspection on re-lay bids. A contractor quotes a tile re-lay only, then finds rotted sheathing on the ridge above Bollinger Canyon Road. The homeowner is mid-project with no approved change order. We inspect decking before we bid, and our written price reflects what we actually saw.
- Undersized ventilation on valley homes. A new roof goes on a home near Dougherty Valley with a hot attic and no added exhaust. The shingle warranty looks fine on paper, but the decking is baking. We size ventilation to the attic, not the roofline.
- Per-square pricing without valley and penetration counts. San Ramon’s two-story hillside plans have dormers, crickets, chimneys, and multiple valleys. A per-square price that doesn’t count those is a lowball. Our written quote itemizes them.
- Wrong underlayment for the exposure. A west-facing ridge gets hammered by afternoon sun and wind. Standard 30-pound felt degrades faster there. We spec high-temperature ice and water shield on ridges and eaves where the microclimate demands it.
Pricing for Roof Installation in San Ramon, CA
Here’s what we actually see in San Ramon. A full architectural shingle tear-off and install on a 2,200-square-foot home runs $14,000 to $24,000. A concrete tile roof on the same footprint runs $22,000 to $45,000, depending on whether the tile is reused or new and how many valleys and penetrations are involved. The three biggest cost drivers are decking replacement (adds $3 to $6 per square foot where plywood is rotted), ventilation scope, and roof pitch and access. Steep hillside roofs require more safety equipment and slower labor.

FAQs About Roof Installation in San Ramon
Compare the square count, the decking replacement allowance, the underlayment spec, and the ventilation scope line by line. A low San Ramon bid usually omits one of those, most often the decking inspection. Ask both contractors whether the written price covers sheathing replacement where rot is found, and get the answer in writing. Call (325) 246-5075 if you want a second set of eyes on a quote you’ve received.
Yes, San Ramon requires a building permit for a full roof installation, and the city inspects the job at key stages. The typical inspection points are the decking and underlayment before the new roof goes on, and again at final for nailing pattern, flashing, and ventilation. We pull permits, schedule inspections ourselves, and you get documentation when the job passes. If a bid doesn’t include permit fees, ask why.
A full tile tear-off and re-install on a typical San Ramon hillside home takes five to nine working days once the permit is approved and materials are staged. The timeline stretches if we find decking rot (we stop, document it, and get written approval before proceeding) or if the roofline has a high number of valleys and dormers. We’ll give you a calendar with your written quote, so you know what’s happening each day.
The only legitimate reason a price changes mid-job is hidden decking damage that couldn’t be seen until the old roof came off. That’s why we inspect the attic and, where possible, lift a few tiles before we quote. If we find rot once we’re into the tear-off, we show you photos, stop work, and get your written approval on the added scope before we proceed. We don’t run change orders on material upgrades or “unexpected” labor.
Architectural shingles from Atlas or GAF work well on San Ramon homes on sheltered lots, and they’re significantly lighter and cheaper than tile. On exposed ridges with high wind and thermal cycling, concrete tile with a high-temperature underlayment is the better long-term system, though it costs more up front. We’ll give you both options priced out for your specific address and exposure, then let you decide. Call (325) 246-5075 for that breakdown.
