Fast, Reliable Roof Repair Across Calabasas
Roof repair in Calabasas runs $350 – $1,450 for most shingle and tile fixes, while more involved underlayment work on luxury tile roofs typically lands between $2,800 and $7,500. We coordinate scheduling from our Los Angeles office and send background-checked crews to Calabasas neighborhoods including The Oaks, Calabasas Park, and Mulholland Highway corridor homes every week. If you’ve spotted a water stain or heard tiles shifting in a Santa Ana wind, call (805) 309-3314 for a written estimate before any work begins.
What makes Calabasas roofing different from nearby cities isn’t just the tile. It’s the combination of Mediterranean villa aesthetics, steep canyon terrain, and fire code requirements that most roofing companies never address. You need someone who understands what’s actually under those tiles and what Calabasas wind events do to it. We do.
Why Mercer Roofing Co Thousand Oaks Is Calabasas’s Preferred Roof Repair Company
Homeowners in Calabasas keep calling us for one reason: they know exactly who is coming to the door before we arrive. Every Mercer technician sends their name and photo ahead of the visit, arrives in a clean uniform, and presents a photo ID badge at the door. That’s the Threshold Verified standard, and it’s non-negotiable on every job we run in Calabasas.
Grant Whitlock leads our team, and his approach is simple. Written price before work starts. Written guarantee on every repair. A 365-Day Done Right Promise that means if the repair isn’t right within a year, we make it right. No fine print. No handshake deals. Calabasas homeowners tend to read contracts carefully, and ours hold up.
We also answer the phone. A live person, 24/7, even during Santa Ana season when roof anxiety spikes. When you call about a loose tile or a leak near your chimney flashing, you talk to a human who can schedule your estimate, not a voicemail that says we’ll get back to you.
Styles & brands we work with





Shingle Roof Repair in Calabasas
Shingle Roof Repair in Calabasas typically runs $350 – $900 for common fixes like replacing wind-damaged shingles, sealing exposed nail heads, or repairing step flashing along dormers and chimneys. Many Calabasas homes built in the 1980s and 1990s still have asphalt shingle sections on secondary roofs, pool cabanas, or garage structures even when the main house wears tile. Those shingle sections age faster under Calabasas’s intense UV exposure.
We stock CertainTeed and Owens Corning shingles in common Calabasas colors, which means we aren’t waiting on a special order for a standard repair. If your shingle match is discontinued, we’ll tell you before we quote and give you options in writing.
Replacing Wind-Damaged Shingles
Santa Ana winds regularly tear shingles off Calabasas roofs, especially on homes along exposed ridgelines. A torn shingle isn’t cosmetic. It exposes the underlayment, and once that breaks down, water gets to the decking. We replace damaged shingles and inspect the surrounding course for lifted nails and weakened seal strips.
Sealing Exposed Nail Heads and Fasteners
UV in Calabasas degrades sealants faster than coastal areas. Nail heads that were properly covered five years ago may now be tiny water entry points. We reseal them as part of any shingle repair, because skipping that step means the leak comes back in eighteen months.
Storm Damage Roof Repair in Calabasas
Storm Damage Roof Repair in Calabasas typically runs $500 – $1,450 for wind-related tile repositioning, flashing repair, and emergency tarps, with more extensive work like underlayment replacement ranging from $2,800 to $7,500 depending on roof size and material lead times. Santa Ana winds don’t just strip shingles. They lift clay tiles, crack corners, and drive embers into places water hasn’t reached in years.
What surprises most Calabasas homeowners is that the visible damage is rarely the whole problem. A shifted tile looks simple until we lift it and find the underlayment below has been baked brittle by twenty years of heat. That’s when a $600 repair becomes a $4,000 repair, and we’ll show you exactly why with photos before you spend a dollar.
Emergency Leak Response During Wind Events
If a branch or wind gust opens a hole in your Calabasas roof during a storm, we can get a tarp on it fast and stop the active leak. The permanent repair follows after the winds die down and materials arrive. We never rush a permanent fix in dangerous wind conditions, and we’ll tell you that plainly.
Flashing and Valley Repair After High Winds
Wind-driven rain finds weak flashing first. Chimney flashing, valley metal, and pipe boots all take a beating during Calabasas wind events. We replace damaged flashing and reseal penetrations using materials rated for the heat and wind cycles this area throws at them.
Trusted Brands We Service in Calabasas
We repair and install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral roofing systems. For Calabasas homeowners, Boral matters most. Boral clay and concrete tiles are common on high-end properties throughout the city, and matching them after a repair requires knowing the specific profile, color lot, and availability. We source these materials ahead of time and lock your price in writing before ordering, so a six-week lead time doesn’t turn into a surprise at the end.

AfterCommon Roof Repair Problems We See in Calabasas Homes
- Degraded underlayment under tile roofs. Many Calabasas homes from the 1990s have clay tiles that look fine but sit on underlayment that’s crumbling from decades of UV and heat. The first sign is often a ceiling stain with no visible roof damage. We find this constantly in The Oaks and Calabasas Park.
- Ember intrusion through open eaves. Santa Ana winds push embers into gaps along eaves and under tiles. Calabasas homes built before current fire codes often have open eave construction that’s critically vulnerable. We inspect these entry points during every repair and recommend sealing them.
- Cracked clay tiles from wind uplift. Santa Ana gusts lift tile edges and snap corners. A cracked tile with intact underlayment isn’t urgent, but once water reaches the underlayment through repeated cracks, the clock starts on decking rot.
- Improper flat roof patches on contemporary homes. Some newer Calabasas homes mix low-slope sections with tile. We see patches where someone used the wrong material on a flat section, and the membrane failed within a year. Flat sections need membrane work, not tile or shingle patches.

FAQs About Roof Repair in Calabasas
Class A fire-rated assemblies require fire-resistant underlayment and sealed eave construction, which means repairing an older Calabasas tile roof often involves more than swapping a few tiles. Many homes along the Mulholland Highway corridor still have degraded wood shake underlayment or open eaves under their tile, which fails current standards. We’ll tell you if your repair touches these areas and what it means for scope and cost. Call (805) 309-3314 if you want a straight answer on your roof’s fire rating.
Custom tile profiles and specific manufacturer colors often take four to eight weeks to arrive, which means a repair that takes two days of labor might wait six weeks on materials. In Calabasas, where Boral tile profiles are common and replacement stock isn’t sitting on a shelf at the supply yard, lead times control the calendar. We lock your written price before ordering so the wait doesn’t change what you pay.
Santa Ana winds hit The Oaks and Calabasas Park from the northeast and lift clay tile edges, crack tile corners, and drive embers into open eaves and under tile gaps. Homes on the exposed western edges of those communities take the worst of it. We inspect for wind damage after every major event and recommend sealing vulnerable eave gaps before the next wind cycle.
Yes, most clay tile roofs in Calabasas can be repaired section by section without a full replacement. We remove damaged tiles, replace the underlayment beneath them, re-bed the tiles with new flashing, and match the existing profile. Full replacement is only necessary when the underlayment has failed across the entire roof or the decking is compromised, which we’ll document before recommending anything.
We work directly with your designer or architect on material selection, color matching, and any changes to flashing or roof details. For custom Calabasas homes, a repair often touches architectural features like eyebrow windows or parapet walls, and those need to be handled with the original design intent in mind. We send photos and written specs so everyone is looking at the same thing before work starts. Call (805) 309-3314 to schedule your free estimate, and we’ll bring the written quote and the badge.
