Roofers in Tarzana, CA
Roofing in Tarzana means working on homes that were mostly built between the 1950s and 1970s, and many of them still carry their original wood shake or early asphalt shingle roofs. The San Fernando Valley sun beats on those materials for decades, while Santa Ana winds tear at loose edges and winter rains find every weak spot. If you’re looking for roofers in Tarzana who understand that mix of aging materials, low-pitch ranch layouts, and the patchwork created by decades of remodels, call Mercer Roofing at (341) 217-2677. We’ll give you a written price before any work begins, and every technician who arrives at your door will have already sent you their name and photo ahead of the visit.
Why Tarzana Homes Are Different
Tarzana’s housing stock runs heavily to single-story ranch homes with low-pitch or flat sections. That shape was popular in the post-war building boom, and it creates a specific set of roof problems. Water moves slowly across a low-pitch roof, so debris accumulates and flashing failures show up faster than they would on a steeper slope. Many original Tarzana homes still have skip sheathing underneath their wood shake roofs, which means a tear-off often requires installing new plywood or radiant barrier sheathing to meet current code. That’s a real cost driver homeowners don’t expect until the old roof comes off.
South of Ventura Boulevard, you’ll find larger custom estates with tile roofs and complex rooflines. North of the Boulevard, the tract homes tend toward asphalt shingle and aging wood shake. A lot of homes have been expanded over the years, so it’s common to see three different roofing materials on a single house, each installed at a different time and each aged differently. That patchwork means a roofer in Tarzana has to be comfortable switching between repair and full replacement on the same job. We are. We work with GAF, CertainTeed, and Owens Corning materials regularly, and we’ll match whatever your roof needs rather than forcing one product onto every home.
Styles & brands we work with
Our Main Tarzana Services
Most Tarzana homeowners reach out to us for one of three reasons: a leak or storm damage repair, a full roof replacement, or a broader roofing assessment before buying or selling a home. Each service has its own detailed page below.
Roof Repair in Tarzana
Repair work in Tarzana often starts with a leak near a chimney, a valley, or a plumbing vent, because those are the places where decades of UV exposure and Santa Ana wind stress show up first. We inspect the flashing, underlayment, and decking around the problem area, then give you a written price for the fix before any work starts. On older Tarzana homes with original shake, a “small” leak sometimes reveals rotted decking underneath, and we’ll show you exactly what we found before we proceed. If a repair fails within 365 days, we return and make it right at no charge. Read more about Roof Repair in Tarzana.
Roofing Company in Tarzana
As a full-service Roofing Company in Tarzana, we handle the full range of work on mid-century ranch homes and the newer custom builds that replaced some of them. That includes full tear-offs where wood shake or failed asphalt comes off and modern underlayment, decking repair, and shingles go on, plus tile roof repairs on larger estates south of Ventura Boulevard. Every project starts with a written quote, and every repair carries a written guarantee. The technician who shows up at your door will be background-checked, identity-verified, and wearing a photo ID badge, sent to you before the visit.
Roof Installation in Tarzana
New roof installation in Tarzana usually means tearing off a roof that’s been on the house since Lyndon Johnson was in office. We assess what’s underneath: skip sheathing, old felt, maybe radiant barrier that was added during a remodel. Then we quote the full job in writing, including decking replacement if needed. We install GAF, CertainTeed, Owens Corning, and IKO shingles, among others, and we’ll walk you through which material fits your roof pitch, your budget, and your HOA rules if you have them.

What pushes a Tarzana roof replacement toward the higher end of those ranges is usually what’s underneath the old roof: skip sheathing that must be replaced, rotted decking around old chimneys, or code-required upgrades like radiant barrier. We’ll show you the full price in writing before the first nail goes in, and that price won’t change unless we find something structural and you approve the change first.
