AfterFast, Reliable Roof Replacement Across Corte Madera
A full roof replacement in Corte Madera typically runs between $14,000 and $28,000 for an average ranch or split-level home, with architectural shingle tear-offs starting around $16,500. Most jobs take three to five working days once materials arrive. The real variable isn’t the shingle price. It’s what the tear-off uncovers underneath, and in Corte Madera, what’s underneath is rarely simple.
We work throughout Corte Madera weekly, from the flatland ranches east of Highway 101 to the hillside homes climbing toward Ring Mountain. Our crews know which side of this town you live on, and we know it changes the roof you need. If you’re weighing a repair against a replacement, or you already know the roof is done, call (945) 303-9821 and we’ll put a written price in your hands before anyone climbs a ladder.
Why Tilehurst Roofing Is Corte Madera’s Preferred Roof Replacement Company
Corte Madera homeowners call us because we answer. A live person picks up at (945) 303-9821 at noon on a Tuesday and at 2 a.m. on a Sunday. The person you talked to yesterday isn’t the crew foreman who shows up, but every technician who arrives is background-checked, uniformed, and works under the same name we gave you on the call. That matters when you’ve been burned before by a no-show or a stranger in an unmarked truck.
We’re part of the Kingswell family of roofing companies, founded in 2000, and we operate under a simple set of rules: 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, come back if it fails. Corte Madera customers don’t get a different version of that promise depending on the crew. They get it in writing, every job, and it’s covered for a full year under our 365-Day Done Right Promise.
Local knowledge here isn’t a talking point. It’s the difference between quoting a roof that lasts and quoting one that fails in a decade. Our estimator walks the roof, checks the flashing, looks at the slope, and knows what Corte Madera’s salt air and bay humidity have already started doing to the metal. That’s why our quotes for Corte Madera homes include line items other roofers skip until it’s too late.
Reroofing in Corte Madera
Reroofing in Corte Madera means tearing off the existing layers down to the decking and building the roofing system back up correctly. Most flatland homes here still carry their original mid-century materials or one thin overlay on top of them. That’s a problem, because Corte Madera’s salt-laden bay air and damp morning conditions have been working on those materials for sixty years, whether anyone could see it or not. A basic asphalt shingle reroof on a 1,400-square-foot ranch in the flatlands runs $14,000 to $19,000. An architectural shingle tear-off with new underlayment, drip edge, and flashing typically lands between $18,000 and $26,000 depending on the roof’s complexity, height, and what the tear-off reveals.
We never surprise you with a price change at the door. The written estimate you approve is the contract. If the tear-off uncovers decking rot or rusted flashing that no one could see from above, we stop, show you what we found, and get written approval on the additional cost before a single board is touched.
Full Tear-Off vs. Overlay
Corte Madera’s building codes and our own standards mean we recommend a full tear-off on nearly every home here. Overlays trap the rot and rust already underneath, and you pay twice when it fails. On low-slope flatland roofs that pool moisture, that failure comes faster than anyone wants.
Decking and Flashing Scope
Any honest reroof quote in Corte Madera should include a line for decking replacement and a separate line for flashing. If a bid has neither, ask why. We write both allowances into the contract up front so you know the worst-case number before we start, not after we’ve opened the roof.
Flat Roof Replacement in Corte Madera
Flat roof replacement in Corte Madera is a different job than it is five miles inland. The low-slope and near-flat sections on post-WWII flatland homes east of Highway 101 trap water after every rain, and the marine moisture off Richardson Bay keeps those surfaces damp longer than roofs in Larkspur or San Rafael. That standing water is exactly what destroys flat roof seams, particularly where the membrane meets pipe penetrations and edge metal. A flat roof replacement on a typical Corte Madera ranch addition or carport runs $9,000 to $16,000 depending on square footage, parapet details, and how many layers need to come off first.
We install both TPO and modified bitumen systems on these homes, and we always bid the job with new edge metal included. Cutting corners on edge metal in Corte Madera means water finds its way under the membrane within a few seasons. We won’t write a quote that way.
TPO Membrane Systems
For most Corte Madera flat roofs, TPO is the right choice. It handles ponding water better than older materials, and it rolls over the low-slope decking cleanly. We stock white TPO locally, which also reflects heat on the flatland homes that bake in summer sun.
Modified Bitumen on Older Decks
Some 1950s flat roofs need modified bitumen instead. It’s a tougher fit for older decking that’s moved slightly over the decades, and it seals well around the odd penetrations and scuppers those mid-century additions always seem to have.
Trusted Brands We Service in Corte Madera
We’re not tied to a single manufacturer. We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral systems, and the choice on your Corte Madera home depends on your roof’s slope, your exposure to wind and salt, and your budget. A GAF architectural shingle handles the wind and moisture better on a exposed Ring Mountain slope, while an Atlas or Tamko line may be the right call on a sheltered flatland ranch. We keep common flashing components and underlayment rolls stocked locally so a Corte Madera job doesn’t slow down waiting for a truck out of the Central Valley. The product fits the home, not just what happens to be in our stockroom.
Common Roof Replacement Problems We See in Corte Madera Homes
- Rusted pipe jacks on 1950s-60s flatland ranchers. The original galvanized pipe jacks on homes near the Corte Madera Creek marsh have rotted through at the seams from salt air and standing water. We find this on nearly every tear-off east of 101, and it means full flashing replacement is part of the job, not an add-on.
- Moss and lichen holding water on north-facing slopes. Marine moisture from two directions keeps roofs damp, and the north and east slopes grow algae, moss, and lichen that trap water against shingles. That organic layer accelerates shingle cupping and shortens underlayment life along valleys and penetrations.
- WUI fire-zone requirements on Ring Mountain-side homes. Once a permit is pulled for a hillside replacement, Marin County inspectors require Class A fire-rated assemblies. That changes the underlayment spec, the venting details, and often the soffit and fascia work. A bid that ignores this will change once the inspector shows up.
- Rot in the decking under decades-old layers. Three-layer tear-offs are common on Corte Madera ranch homes. The lower layers are almost always rotted through at the eaves and valleys, especially where decades of damp bay air never fully dried out. We write a decking allowance into every Corte Madera quote so that cost is known before work starts.
Pricing for Roof Replacement in Corte Madera, CA
Here’s what you can expect on a Corte Madera roof replacement, based on the homes we’ve bid and built in this town. A straightforward asphalt shingle reroof on a 1,200 to 1,600-square-foot ranch runs $14,000 to $19,000. Architectural shingles run $18,000 to $26,000 on the same footprint. Flat roof sections add $9,000 to $16,000 depending on the system and square footage. Hillside homes on the Ring Mountain side run higher because of steeper roof pitches, safety tie-offs, and the WUI fire-rated materials the permit requires. Those jobs typically land between $25,000 and $38,000. Every quote includes a written decking allowance, flashing allowance, and no change orders above those allowances without your written approval first. Call (945) 303-9821 and we’ll put a real number in your hands before any work starts.

FAQs About Roof Replacement in Corte Madera
Because the original galvanized pipe jacks and valley metal on low-lying homes east of 101 have been corroding in salt-laden bay air and standing water for sixty years, and that failure mode shows up about a decade earlier here than in San Rafael. By the time we tear off a Corte Madera ranch roof, the flashing is typically rusted through at the seams, and trying to reuse it would mean re-roofing again in a few years. Full flashing replacement is mandatory on any flatland re-roof here, not an upsell. Call (945) 303-9821 and we’ll show you exactly what’s on your roof and why it can’t be saved.
Yes, if you’re in the Wildland-Urban Interface zone, which covers most of the western hillside, Marin County will require a Class A fire-rated roofing assembly as part of the permit. That means specific underlayment, venting, and often soffit and fascia corrections that aren’t part of a flatland quote. We pull the permit, coordinate the inspection, and build the fire-rated assembly into the bid from day one so the price doesn’t move when the inspector walks the site.
We write decking and flashing allowances into the contract before we start, based on what we expect to find on a Corte Madera home of your era and location. If the tear-off reveals damage beyond those allowances, we stop, show you the bad wood or metal, and get your written approval on the added cost before we touch it. You never pay for a surprise you didn’t see and approve first. That’s not our policy. That’s the contract.
This town gets moisture from two directions, Pacific fog through the Marin valleys and humidity off Richardson Bay, and it keeps roof surfaces damp well into the morning. North and east slopes rarely dry out completely, so moss and lichen colonize and hold water directly against the shingles and underlayment. The fix is proper ventilation, quality underlayment, and shingles rated for algae resistance, which we specify on every damp-slope Corte Madera roof.
Put the two line items side by side, and check for the same things: the flashing scope, the decking allowance, the underlayment spec, and whether fire-rated materials are included if you’re on the Ring Mountain side. A lower bid that omits flashing or fire-rated underlayment isn’t lower. You’ll pay for it later, either in change orders or in a roof that fails early. Call (945) 303-9821 and we’ll walk you through the line items on any bid you’re considering, ours or anyone else’s. Estimates are free.
