Fast, Reliable Roof Replacement Across Alhambra
A full Roof Replacement in Alhambra for a typical 1,200 to 1,800 square-foot single-story home runs $9,500 to $18,500 depending on material, tear-off depth, and decking condition. Most Alhambra jobs finish in two to four working days once materials are on site. We know the city’s street-tree canopy, narrow lot lines, and 1910s-to-1980s housing mix well enough to stage tear-off and delivery without turning your driveway into a week-long obstacle course.

Why Marquis Roof Repair Is Alhambra’s Preferred Roof Replacement Company
We are not the loudest roofer in the San Gabriel Valley. We are the one local homeowners call when they want the roof diagnosed honestly before anyone talks replacement. Ron Thibodeau built Marquis around that repair-first habit: investigate the decking, flashing, and underlayment before recommending a full tear-off. In Alhambra, where many roofs have multiple layers and hidden decking rot under the tree drip lines, that diagnostic step saves homeowners from paying for work they do not need yet.
Our crews work frequently in 91801, 91803, and the numbered streets running south from Main Street toward Valley Boulevard. That means we schedule Alhambra estimates within a few days, not weeks, and we know which blocks have the tightest staging constraints before we ever park a truck. We carry seven manufacturer lines, including GAF, Owens Corning, and CertainTeed, so the right material for a pre-war Spanish Colonial Revival bungalow is as available as the right material for a 1970s infill ranch.
We hold a strong local reputation built on written line-item quotes and fixed pricing with no change orders. When we say a roof will cost a number, that is the number.
Styles & brands we work with
Reroofing in Alhambra
Reroofing in Alhambra is rarely a cosmetic decision: it is a required maintenance event on homes whose original three-tab shingles and felt underlayment have outlived their intended service life. We tear off the old layers, inspect the decking, replace whatever has rotted or delaminated, install new underlayment and shingles, and finish with new drip edge and flashing. On a typical Alhambra bungalow, a complete reroof runs $9,500 to $14,500 for architectural asphalt shingles. Tile or clay replacement on Spanish Colonial Revival homes runs higher, usually $18,000 to $26,000, because of material weight and tear-off labor.
What We Find Under the Old Shingles
The third or fourth layer on a 1940s Alhambra roof hides what the first layer did to the decking. Original 1×6 plank decking often holds up fine, but years of trapped moisture under triple-layered three-tab leaves soft spots along eaves and valleys. We replace only the damaged sections. We do not sell you a full deck when three boards will do.
When Reroofing Beats Patching
If you have paid for two valley repairs in three years, or if south-facing slopes show granule loss exposing the mat, patching is money spent on a roof that has already failed. The repair-first philosophy cuts both ways. Sometimes the repair is not the honest answer; the replacement is.
Flat Roof Replacement in Alhambra
Flat Roof Replacement in Alhambra mostly shows up on post-war additions, carports, and a few 1960s apartment buildings along Valley Boulevard and the numbered avenues. These roofs fail differently than pitched roofs: water ponds, seams open, and the underlayment underneath a cap sheet or built-up roof quietly rots the plywood. A flat roof replacement on a 300 to 600 square-foot Alhambra addition runs $4,500 to $9,000 for a modified bitumen or TPO system, installed with tapered insulation where ponding is chronic.
The Ponding Problem
Alhambra’s flat roofs get almost no snow, but they get winter downpours that sit in low spots for days. If water still stands 48 hours after a storm, the roof is not draining and the membrane is working harder than it should. We correct slope with tapered panels during replacement rather than just gluing a new membrane over a bad one.
Carport and Addition Roofs
Many Alhambra carports were built with minimal slope and cheap cap sheet. When those roofs fail, they leak onto the car, the storage, or worst, the connecting wall into the house. Replacing them correctly means addressing the transition flashing where flat roof meets the pitched main roof. That intersection is where most flat roof leaks actually begin.
Trusted Brands We Service in Alhambra
Marquis Roof Repair installs and services roofing from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Alhambra homeowners, that breadth means something practical: when you choose Atlas or IKO for a specific wind rating or a CertainTeed line for a particular architectural profile, we can supply and install it without switching contractors. We keep common shingle profiles and underlayment stock moving through our Burbank yard, so material lead times for Alhambra replacements stay short. The right material for your roof should be a recommendation, not whatever is left in a warehouse.
Common Roof Replacement Problems We See in Alhambra Homes
- Builder-grade three-tab on 1960s and 70s infill homes: These shingles wear out uniformly, shedding granules first on south-facing slopes. By the time a homeowner notices, the mat is exposed and the roof is past repair.
- Original felt underlayment that tears during tear-off: On homes from the 1950s through the 1980s, the underlayment is often brittle and cracked. Leaks show at penetrations and flashing long before the shingles look failed.
- HOA approval delays on visible changes: Some Alhambra HOAs, particularly in the newer developments and gated communities near the 710 corridor, require architectural review for material or color changes. Skipping that step means rework or fines after the roof is already on.
- Decking rot along eaves and valleys from tree debris: Mature ficus and camphor trees on the numbered streets drop leaves that clog valleys and hold moisture against the roof edge. We find rotten decking at these spots on a majority of older Alhambra replacements.

FAQs About Roof Replacement in Alhambra
Yes, in most cases a roof replacement performed by a licensed contractor using materials that meet or exceed the original specification does not void a structural builder’s warranty. The key is documentation: save the material specs, the permit, and the final inspection record. If a warranty claim arises later, that paper trail shows the work was done to code. Call (866) 705-2978 and we will walk you through what your specific warranty requires before we touch the roof.
The three upgrades that pay off most on a 1980s Alhambra home are synthetic underlayment instead of felt, architectural shingles instead of three-tab, and a ridge vent if the home lacks one. Synthetic underlayment lasts longer and resists tearing during installation. Architectural shingles carry better wind ratings. A ridge vent improves attic ventilation, which matters in Alhambra’s hot summers. Call (866) 705-2978 for line-item pricing on each option.
If your home is in an HOA-governed development, most CC&Rs require architectural review before any exterior change, including roof material or color. Some Alhambra HOAs approve replacements quickly if you are restoring the original look; others take 30 days or more. Start the approval process before you sign a contract so the roof does not sit waiting for a committee meeting. We routinely prepare material spec sheets for HOA submittals at no charge.
Put the bids side by side and compare four lines: number of tear-off layers included, underlayment type, shingle brand and model, and decking repair allowance. A $12,000 bid that includes two-layer tear-off and synthetic underlayment is a better deal than a $10,500 bid that assumes single-layer tear-off and uses felt. Call (866) 705-2978 and we will explain our bid line by line.
For Alhambra, look for shingles rated for at least 110 mph wind uplift, which covers the worst Santa Ana wind events this part of the valley sees. Most architectural shingle lines from GAF, Owens Corning, and Atlas carry ASTM D3161 Class F or ASTM D7158 Class H ratings at or above that threshold. Three-tab shingles typically do not. Call (866) 705-2978 for a free estimate that spells out the wind rating on every shingle we quote.
Local Context: Alhambra’s Post-War and Infill Rooftops
Alhambra is not a new-construction city. The housing stock along the numbered streets north of Valley Boulevard and the neighborhoods east of Garfield went up between the 1910s and the 1950s, and the infill homes that filled the gaps in the 1960s through the 1980s often carried builder-grade three-tab shingles and original underlayment that age out before the rest of the house does. On those homes, replacement timing is driven by roof age, not storm damage. A roof put on in 1978 is 47 years old. It does not need a wind event to fail; it just needs another hot summer.
One field example from the team: we replaced a builder-grade three-tab roof on a 1970s infill home near Valley Boulevard with GAF Timberline HDZ architectural shingles, upgraded the underlayment to synthetic felt, and added a ridge vent. The original decking was sound, so we kept it and put the budget into new drip edge and flashing around the penetrations. The homeowner spent less than they expected because we did not sell them a deck they did not need.
That is the Marquis standard. From first inspection to final shingle, we investigate before we recommend, and we build every Alhambra roof to outlast the next heat wave and the next winter’s tree debris.
