Fast, Reliable Roof Replacement Across Danville
A full roof replacement on a Danville home typically runs between $14,000 and $42,000 depending on square footage, material tier, and whether the old roof is stripped to decking or overlaid. The good news: you’ll know your exact number in writing before we order a single square of material. Call (945) 303-9821 and we’ll walk the roof with you, explain what’s actually failing, and hand you a price that won’t move when the crew shows up.
We know Danville roofs because we work on them every week, from Blackhawk’s tile-clad hillsides to the older composition shingle homes near the historic downtown core off Railroad Avenue. The valley heat, the Diablo winds, the long bone-dry summers – all of it shapes how roofs fail here, and how a replacement should be scoped. Greg Holloway leads our crews, and he’d rather spend an extra twenty minutes on your roof than sell you a fix that won’t survive the next wind season.
Why Tilehurst Roofing Is Danville’s Preferred Roof Replacement Company
Homeowners in Danville call us because they’ve already been through the ringer with a contractor who didn’t show, or did show with a number that changed once the materials hit the driveway. We don’t operate that way. Every Tilehurst job starts with a written price before any work begins – not an estimate, not a ballpark, a fixed figure you can hold us to. That’s the Kingswell Way, and it’s been the standard across the Kingswell family of roofing companies since 2000.
When you call, a live person answers. Not a voicemail. Not a call center script. Someone who knows roofing, knows Danville, and can put you on the schedule with a window the crew will actually keep. We show up in branded trucks, with background-checked technicians in uniform, and we leave the job site cleaner than we found it – gutters cleared of debris, nail sweep done with a magnet, bushes covered before stripping begins.
And because Blackhawk tile work is a significant share of what we do in Danville, we’ve learned how to sequence these projects around the long-lead materials. The foam-set ridge tile and Class A underlayment systems aren’t sitting on a shelf in a local yard. We order them the week you approve the quote, so your roof doesn’t sit open waiting on a supplier.
Asphalt Shingle Roof Replacement in Danville
Asphalt Shingle Roof Replacement on a Danville home is the most common full replacement we perform, particularly on the mid-century wood-frame houses east of Camino Tassajara and the older subdivisions near Sycamore Valley Road. A full tear-off and re-shingle with a 30-year architectural shingle runs roughly $16,000 to $28,000 on a two-story 2,200 to 3,200 square-foot house. That includes decking inspection, synthetic underlayment, new drip edge, new flashing at penetrations and valleys, and a written guarantee you’ll have in hand before the crew leaves.
Danville summers routinely hit 95°F to 105°F. That kind of sustained heat cooks old composition shingles from the underside, drying out the asphalt and making the granule surface rough and bald within two decades. If you’re seeing excessive granule washout in your gutters, shingle edges curling hard, or brittle cracking at the ridge line, the roof is telling you it’s done. We’ll strip it, inspect the decking – and in older Danville homes, that’s often where the real cost appears.
Decking and Dry Rot Repairs Before Shingle Application
Most Danville homes we re-shingle need at least some decking replacement, particularly around chimneys, skylights, and the north-facing eaves that stay damp through the winter months. We don’t patch over rotted decking. We cut it out, replace it with code-grade plywood or OSB, and document every square of it with photos so you can see exactly what was done beneath the shingles you can see. That’s standard on every job, not a premium add-on.
Architectural vs. Three-Tab: What Makes Sense for Danville’s Heat
Three-tab shingles are cheaper, and they fail faster in Danville’s thermal cycle. The strips between the tabs expand and contract daily across a 40-degree temperature swing, and after a few summers the tabs begin to crack and lift. Architectural shingles, the thicker laminated ones, hold their seal better and carry higher wind ratings – which matters when Diablo winds hit 40 to 60 mph along the open ridges. The price difference on a full roof is around $3,000 to $5,000, and over a 30-year life expectancy it’s money well spent in this valley.
New Roof Installation in Danville
New Roof Installation in Danville means two very different things depending on where you live: new construction on a hillside lot, or a complete re-roof on an existing home that’s beyond repair. For new construction along the WUI boundary near Mount Diablo State Park, you’re almost certainly required by Contra Costa County code to build a Class A fire-rated assembly, which eliminates wood shake entirely and narrows brand options for tile and composite systems. Tilehurst handles new construction and full re-roofs with the same written-price discipline, whether the architect is sending us drawings or we’re measuring an existing roof by hand.
New roof installation on a custom build starts around $28,000 and can run well past $60,000 depending on roof complexity, material spec, and structural engineering requirements. That’s a bigger number, and it deserves a bigger conversation. Greg Holloway will sit with you or your builder and walk through every line item – underlayment grade, flashing method, ridge attachment, ventilation strategy – before anything gets signed.
Coordinating With Your Architect During a Danville Build
We work directly with architects and general contractors across Danville, so when a roof design calls for a specific Boral or certain type of tile profile, we’re already in the conversation early enough to order it before it becomes the schedule bottleneck. Long lead times on specialty tile – not labor – are what drive the calendar on custom Danville projects. We build the material order into the initial write-up so the roof doesn’t stall an entire build over a six-week tile delivery.
Trusted Brands We Service in Danville
Danville homeowners deserve real choice, not whatever happens to be on the truck. Tilehurst Roofing installs materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. On a given job we’ll typically recommend two or three of these based on your roofline, sun exposure, and – in the hillside WUI zones – your fire-rating requirement, but the decision is yours. For Blackhawk concrete tile re-roofs, we regularly specify Boral tile where the profile matches the original 1980s-90s look, and we stock local relationships in the Danville area to keep turnaround on standard materials tight.
Common Roof Replacement Problems We See in Danville Homes
- Carbonated mortar at hips and ridges in Blackhawk. The original mortar-set concrete tile ridges from the 1985-1995 build-out era have now fully carbonated. After a strong Diablo wind event off Mount Diablo’s northeast face, we see ridge caps blown off in clusters across entire streets – not one house, but ten. It’s a neighborhood-scale failure pattern unique to this valley corridor.
- Concrete tile underlayment at end of life. Danville’s 95-105°F summers bake the underlayment beneath concrete tile roofs so hard that by year 30-40 it has cracked, peeled, and lost its water-shedding capacity. The tiles on top can look fine while the waterproof layer beneath them has failed. That’s why leaks in a Blackhawk home often appear during January storms without any visible tile damage.
- Masked leaks from the long dry season. Danville can go from May through October with essentially no rain. A failing underlayment doesn’t reveal itself during that stretch, so the first real storm in January or February turns it into sudden ceiling stains and interior damage all at once. This is the single most common story we hear from Danville homeowners after the holidays.
- WUI fire-rating constraints on hillside replacements. Homes along the wildland boundary near Mount Diablo State Park face stricter Class A assembly requirements than flatland Danville neighborhoods or nearby cities like San Ramon. That eliminates wood shake and certain non-rated tile, and it changes the conversation about which replacement materials are even legal to install.

FAQs About Roof Replacement in Danville
Ridge caps blow off in Blackhawk because the original mortar that set them on homes built between 1985 and 1995 has fully carbonated. It has turned to powder, essentially, and once the mortar bond fails the only thing holding those caps in place is gravity – which is not enough when a Diablo wind event funnels through the San Ramon Valley at 40 to 60 mph. We replace the entire ridge line with foam-set caps or fresh mortar-bed caps, which are adhered under the cap and hold far better than the original mix. Call (945) 303-9821 if your neighbor’s caps are already gone – yours are likely next in the same wind path.
Yes, if your home sits in the Wildland-Urban Interface zones along Danville’s eastern and southern edges near Mount Diablo State Park, you are effectively required by Contra Costa County code to install a Class A fire-rated roof assembly on any replacement. That eliminates wood shake and most non-rated tile, and it narrows your material options down to Class A composition shingles, Class A coated metals, and specific Class A rated tile or composite systems. We can verify your property’s specific requirement and build the material spec around it before you order anything. Call (945) 303-9821 for a free assessment.
Because the underlayment beneath your tile is the waterproof layer, and in a 1990 Blackhawk concrete tile roof that underlayment is now 35 years old. Danville’s summer heat accelerates its decay, and the long dry season from May to October masks the failure until a January storm suddenly channels water through to your ceiling. The tiles can look completely intact above while the layer doing the actual waterproofing is shot. We can lift a few tiles, inspect the underlayment, and show you photos of what’s actually there before you commit to anything. Call (945) 303-9821 to schedule that inspection.
We fix the price in writing before we order any material, and we include the current long-lead estimates for foam-set ridge caps, Class A underlayment systems, and specific Boral tile profiles in that number. If a ridge tile is six weeks out from the manufacturer, that’s already in the schedule, and your price doesn’t change if the supplier’s cost shifts between approval and delivery. You’ll know the full scope, the full schedule, and the full dollar figure before a single tile is stripped off your Blackhawk roof. Call (945) 303-9821 for a written quote.
Ask each contractor these four questions: First, is this price fixed in writing, or does it change once the decking is exposed? Second, will you strip to decking and inspect it, and how do you handle rot replacement? Third, what Class A fire-rated assembly are you specifying and can you show me the underlayment grade you’re using? Fourth, who exactly will be on my roof – are they background-checked employees or day labor? If a contractor can’t answer all four in plain language with a written quote, you’re not comparing apples to apples. We answer all four in our first visit. Call (945) 303-9821 and put us to the test.
If you’re looking at a roof replacement in Danville, the first step is a conversation. We’ll walk the roof with you, show you what’s failing and what isn’t, and hand you a written price that doesn’t move. Greg Holloway and the Tilehurst team answer the phone when you call, 24 hours a day, seven days a week.
