Roof Replacement in San Gabriel — Free Roof Inspection, Written Price

Fast, Reliable Roof Replacement Across San Gabriel

Roof replacement in San Gabriel typically runs $11,000 – $24,000 for a full tear-off and reroof on a standard single-story home, with architectural asphalt shingles landing between $14,000 and $19,000 for most properties in the 91775, 91776, and 91778 zip codes. Clay tile or concrete tile work in the historic core runs higher, often $22,000 – $38,000 once decking, design review, and material matching are factored in. Marquis Roof Repair serves the entire San Gabriel Valley from our Burbank base, and we know exactly what opening up a 1920s or 1930s roof here turns up: skip sheathing, baked-out underlayment, and flashings that fail the first time a Santa Ana wind hits.

This is not a guess-and-bid operation. Ron Thibodeau built Marquis Roof Repair around a simple discipline: investigate before recommending. That matters more in San Gabriel than almost anywhere in the Valley, because what hides under an older roof here changes the entire scope of the job.

Why Marquis Roof Repair Is San Gabriel’s Preferred Roof Replacement Company

San Gabriel homeowners call us because we carry seven manufacturer lines, GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the recommendation you get is driven by your roof, your slope, and your budget, not by whichever brand happens to be sitting in our warehouse that week. We’re brand-agnostic by design. If a 1940s Craftsman bungalow near the Mission District needs a clay tile profile that matches the original, we specify it. If a post-war minimal traditional in the neighborhoods north of Las Tunas Drive is better served by an Owens Corning architectural shingle with a high wind rating, that’s what we quote.

Our Roof Replacement team has torn off enough roofs in San Gabriel to know what the bid should anticipate before demolition starts. We write redeck allowances into the contract when we suspect skip sheathing. We flag historic-overlay exposure on street-visible slopes. We inspect the attic, the rafters, and the existing underlayment before we put a number in front of you. That’s the Marquis standard, and it’s why homeowners from San Marino to Monterey Park send their neighbors our way.

Ron Thibodeau’s name is on the business. He’s licensed, insured, and personally walks complex San Gabriel jobs before the crew arrives. When you call, you’re not getting a sales rep reading from a script. You’re getting a roofer who has seen what a 1930s tile roof looks like from the underside and knows what it costs to make it right.

Reroofing in San Gabriel

Reroofing in San Gabriel means a full tear-off of the existing roof down to the decking, replacement of any failed sheathing or underlayment, and installation of a new roofing system. Most San Gabriel homeowners need a reroof when their original 1920s – 1950s roof has reached the end of its service life, when leaks have become recurrent rather than isolated, or when the underlayment under clay tile has baked out after seventy-plus years of San Gabriel sun and the first winter storm pushes water through the cracks. A typical reroof in San Gabriel runs $12,000 – $22,000 for asphalt shingle, and $20,000 – $35,000 when clay or concrete tile and historic-design compliance are involved.

What Tear-Off Reveals

On the older bungalows around the Mission District, a tear-off routinely exposes original 1x skip sheathing instead of solid decking. The homeowner expected a straightforward tile re-roof. The reality is a full redeck once the old clay tile comes off, because you cannot nail new tile or shingles to boards spaced four inches apart. We look for the signs before demolition, nail patterns, attic visibility, deck flex, and we put a written allowance for redecking into the contract so the number doesn’t move mid-job.

Permits and Design Review

If your San Gabriel home sits in the historic overlay, any street-visible slope must match the original material profile. That’s not a suggestion from city hall. It’s a condition of the permit. We handle the drawings, the submittal, and the design-review meeting, because we’ve done it repeatedly for homes along Mission Drive and the surrounding blocks. The right material for your roof is the one that passes review and protects the house.

Flat Roof Replacement in San Gabriel

Flat Roof Replacement in San Gabriel is most common on post-war minimal-traditional homes and on the low-pitch additions that were tacked onto 1920s bungalows in the 1950s and 60s. These roofs fail differently than steep slopes. Water ponds, underlayment degrades, and the seams at valleys and penetrations start to leak. In San Gabriel’s hot, dry climate, the UV degradation of flat roof membranes happens faster than most homeowners expect, and the original install often skipped ice and water shield where it was needed most. A flat roof replacement in San Gabriel typically runs $9,000 – $16,000 depending on the system specified and the condition of the decking beneath.

Membrane and Taper Systems

We quote flat roofs based on what the drainage and deck actually require, not a one-size-fits-all membrane. For homes in the 91776 area with near-flat slopes, that often means a tapered system to move water toward existing drains, plus new edge metal and penetration flashings. We inspect first, measure the actual slope, and then recommend the material that will hold up to San Gabriel’s UV load without premature cracking.

Decking and Code Upgrades

When we open a flat roof on an older San Gabriel home, we frequently find rotted plywood at the low points and outdated wiring for rooftop AC disconnects that no longer meets current code. A permit triggers the upgrade. We write that allowance into the contract before demolition starts. From first inspection to final shingle, or membrane, the number in front of you is the number you pay unless we document a change in writing and you approve it first.

Trusted Brands We Service in San Gabriel

Marquis Roof Repair is authorized to install roofing systems from seven major manufacturers, and for San Gabriel homeowners that means real choice. We stock and order GAF, CertainTeed, and Owens Corning lines regularly, and we specify Boral clay tile when a historic-overlay slope demands a true period profile. Because we’re not tied to a single brand, your replacement gets specified around what your roof needs, not what a distributor put on a spring promotion. Seven manufacturer lines, one point of contact. The warranty options vary by product line, and we walk you through what each one actually covers before you choose.

Common Roof Replacement Problems We See in San Gabriel Homes

• Skip sheathing under old clay tile. Homes built in the 1920s and 30s near the Mission often have 1x boards spaced four to six inches apart instead of solid plywood or OSB. You can’t nail new roofing to that, so a redeck becomes mandatory, and it should be priced into the bid before tear-off starts.
• Historic-overlay design review rejections. If your street-visible slope doesn’t match the original clay tile profile, the city won’t sign off on final inspection. We handle the submittal and specify a matching profile from Boral or similar so the job passes the first time.
• UV-baked underlayment and dried flashings. San Gabriel’s sun is relentless. After sixty or seventy years, the underlayment under tile turns to dust, and the first Santa Ana wind lifts shingles and ridge caps that looked fine from the ground. We replace underlayment on every reroof, not just the visible surface.
• Low-pitch leaks at valleys and penetrations. Post-war tract homes in the 91778 area were often built with minimal slope and no ice and water shield at the valleys. We install ice and water shield in every valley and around every penetration on our replacements, which stops the recurring leak pattern for good.
