Roof Replacement in Whittier — Written Price, Workmanship Warranty

Fast, Reliable Roof Replacement Across Whittier

A full roof replacement in Whittier typically runs $11,000 – $24,000 for a standard asphalt shingle home, and $18,000 – $40,000+ when the job involves lifting and relaying original clay tile over new underlayment. Most Whittier homes we replace fall into one of two camps: pre-1950s Spanish Revival and Craftsman homes with tile or wood shake, or 1950s-60s ranch tracts still on their original 3-tab. We work both, and we’ll tell you straight whether you need a full replacement or a targeted repair. Call (877) 755-4274 and we’ll walk the roof with you before you spend a dime.

Weathervane Roof Repair is a roof-only specialist out of Glendale, and we’re on Whittier roofs every week. We know the difference between a Uptown tile roof from 1931 and a South Whittier ranch roof from 1963, because we’ve stripped, repaired, and replaced both. That local knowledge changes what we quote and how we build the scope.

Key Takeaways

• Whittier roof replacement typically costs $11,000 – $24,000 for asphalt, more for clay tile relay work.

• Acreage parcels east of 90603/90604 frequently fall under LA County permitting, not City of Whittier.
• We scope grading, drainage, access, and staging before we quote – not after you sign.
• Free estimates. Call (877) 755-4274 to schedule yours.

Why Weathervane Roof Repair Is Whittier’s Preferred Roof Replacement Company

Whittier homeowners call us because we don’t open with a replacement pitch. We open with an inspection. Gil Tanner built Weathervane around a repair-first philosophy: if a $600 repair fixes the leak, that’s what we recommend. If the decking is shot and the underlayment is dust, we’ll show you the photos and walk you through the replacement numbers. No pressure, no vendor allegiance, just an honest read on what your roof actually needs.

Our Whittier customers regularly tell us the same thing: they’d already had two or three bids before we showed up, and nobody had gone into the attic or pulled back a tile to check the underlayment. We do. That’s the difference between a roofer who measures squares and a roofing specialist who diagnoses the system. Our Roof Replacement team works with GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the material recommendation fits your roof, your budget, and Whittier’s sun exposure, not our supplier’s inventory.

We’re licensed, insured, and bonded, and our workmanship warranty applies to every Whittier job. When you call, you reach a roofing company, not a call center.

Roof Installation in Whittier

Roof Installation in Whittier means tearing off the old system and building a new one from the decking up. On the 1920s-40s homes in the Uptown and College areas, that often means lifting the original clay tile, replacing the felt underlayment that’s baked to dust, repairing rotted decking, and resetting the same tiles. The tiles are usually fine. The paper underneath is not. On the 1950s-60s ranch tracts in the 90603 and 90604 ZIPs, roof installation typically means a full tear-off of the original 3-tab, decking repairs if the low-pitch roof has been ponding water, and new architectural shingles with proper valley protection and ridge venting. A standard tear-off and re-shingle on a ranch home runs $11,000 – $18,000. Tile relay work on an older home runs $18,000 – $40,000 depending on how much decking needs replacement.

New Construction Roofing

We roof new detached garages, shops, ADUs, and outbuildings on Whittier acreage lots. The scope includes dry-in, underlayment, shingle or tile system, flashing at all transitions, and ridge venting. New construction roofing means we coordinate with the framing schedule so the roof goes on before the weather turns.

Architectural Shingle Systems

Architectural shingles hold up better than 3-tab under Whittier’s inland sun, and they’re what we recommend for most replacement jobs on ranch and tract homes. They carry a longer material warranty, resist lifting during Santa Ana wind events, and give the roof a dimensional look that suits the neighborhood. We stock architectural lines from Owens Corning, CertainTeed, and IKO for Whittier jobs.

Roof Replacement Contractor in Whittier

A Roof Replacement Contractor in Whittier should be able to explain the full scope before the dumpster shows up, and that’s where we earn our keep. We measure the roof, check the attic, look at the fascia and drip edge, walk the drainage path, and then build a line-item quote. On Whittier acreage parcels, that also means checking whether the lot falls under LA County building jurisdiction and whether a detached shop or ADU is part of the same permit scope. A full replacement on a standard Whittier ranch runs $11,000 – $18,000; on a tile home needing a lift-and-relay, $18,000 – $40,000. Multi-structure lots with outbuildings run higher because of haul distance, staging, and additional permit fees.

Roof Decking Replacement

Whittier’s older homes hide rotted decking under tile and shake. By the time the underlayment fails, water has often been sitting against the plywood or skip sheathing for years. We price decking replacement per sheet and only after we’ve pulled the old system and can see what’s actually there. You’ll know the per-sheet cost before we start, and you’ll approve any additional replacement sheets with photos in hand.

Flat Roofing Systems

Flat and low-slope sections on Whittier homes – porch roofs, carport covers, additions – need a different system than the pitched field. We install modified bitumen and single-ply membrane systems with proper tapered drainage so water doesn’t pond at the wall. On low-pitch 1950s ranch roofs where architectural shingles aren’t rated, we’ll recommend the correct system instead of forcing a product that’ll fail.

Trusted Brands We Service in Whittier

We’re brand-agnostic, and that matters in Whittier. A Uptown clay tile home, a Friendly Hills estate, and a 90604 ranch tract home all need different materials. We work across GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we stock local parts and materials for Whittier jobs so we’re not waiting on a supplier in Riverside when your roof is open. Seven leading brands, one honest recommendation. That’s how we quote.

Common Roof Replacement Problems We See in Whittier Homes

• Baked underlayment under original clay tile: The tiles on Uptown and College-area homes routinely outlive their felt by 30 years. We lift, replace the paper, repair the decking, and reset the same tiles – a replacement without throwing away good material.
• Santa Ana lift on short-cupped 3-tab: Low-pitch 1950s ranch roofs in the 90603/90604 ZIPs lose shingles at the first strong wind event because the old 3-tab is cupped and brittle. A full replacement with architectural shingles and a starter strip fixes the edge lift permanently.
• Drainage failures on acreage lots: Open-lot grading sends winter sheet flow against outbuilding walls and rotted fascia. We re-grade the slope side of the structure when we replace the roof, because a roof-only bid that ignores drainage fails within a season.
• Clogged valleys before the first rain: Whittier’s long dry season drops debris into roof valleys, and when the winter rain comes, water backs up under the shingles. We clear and rebuild valley protection as standard on every replacement.
