Fast, Reliable Roof Replacement Across Alhambra
Roof replacement in Alhambra means dealing with homes built between 1920 and 1955, many with original clay tile and decking that’s now pushing a century old. We know the difference between a roof that needs patching and one that needs full replacement, and we’ll tell you straight. Our crew works throughout 91801, 91803, 91804, and the surrounding San Gabriel Valley, and we answer our own phones. If you’re looking at cracked tile, water intrusion, or sheathing that’s failed under your existing roof, call (866) 321-6172 and we’ll schedule an inspection first.
We’re not going to sell you a replacement if a repair makes more sense. That’s the point of working with a company whose Roof Replacement team also handles repairs and inspections in-house. One crew, one assessment, one honest answer.
Why Van Nuys Roofing Co Is Alhambra’s Preferred Roof Replacement Company
Alhambra homeowners have a specific problem most roofers can’t solve: the city’s historic preservation design review. Homes in the tracts north and south of Main Street often carry original mission clay tile, and when that tile fails, you can’t just swap in modern concrete. The city requires matching profiles. We source authentic and custom-profiled clay tile, which means your replacement actually gets approved instead of stalled at the permit counter.
Rick Dominguez runs our crews, and he’s made material-neutral recommendations the core of how we operate. We work across GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That matters in Alhambra because no single manufacturer makes the right product for every home here. A Spanish Colonial on a historic block needs something different from a postwar ranch on the east side.
We also offer a standalone roof inspection. No repair purchase required. If you want an honest condition assessment before deciding between repair and replacement, we’ll walk your roof, document what we find, and give you the numbers. Call (866) 321-6172 to schedule one.
Styles & brands we work with






Flat Roof Replacement in Alhambra
Flat Roof Replacement in Alhambra typically applies to the low-slope porch roofs, carport covers, and 1950s multi-family buildings that make up a large share of the city’s older housing stock. A full flat roof replacement on a typical Alhambra bungalow porch runs $2,800 to $6,500 depending on square footage and whether we’re replacing decking. For a mid-century duplex or small apartment building, you’re looking at $8,000 to $18,000.
Flat roofs fail differently than pitched roofs. Water pools, sealant cracks under UV, and the San Gabriel Valley smog basin accelerates membrane breakdown. When we inspect a flat roof here, we check the drain points first. Clogged drains in Alhambra are common because of the sycamore and jacaranda leaf litter.
Porch Roof Replacements
The low-slope porch roofs on 1920s bungalows are where we find the most hidden damage. Original clay barrel tile sits over hundred-year-old sheathing. The tile looks fine from the street, but underneath, the wood has absorbed decades of moisture. We replace the decking, install a peel-and-stick underlayment, and re-lay tile that matches the original profile.
Multi-Family and Rear Addition Roofs
Alhambra’s mid-century duplexes and small apartment buildings often have flat or near-flat roofs that were originally built with hot-mop or early membrane systems. Those systems age out. We handle full tear-off, decking repair, and modern membrane installation on these buildings without requiring you to coordinate multiple contractors.
Roof Installation in Alhambra
Roof Installation in Alhambra covers two very different situations: new construction, which is rare in the dense historic districts but more common in the 91803 and 91804 areas, and full replacement where we’re installing an entirely new roofing system. A new asphalt shingle roof on a typical 1,200 to 1,600 square foot Alhambra ranch runs $9,500 to $16,500. A tile re-roof on a Spanish Colonial, including matching profiles and new underlayment, runs $22,000 to $45,000.
New construction near Alhambra means working within city setback requirements and, in the historic zones, matching the architectural character of the surrounding block. We handle the roof from deck to cap and coordinate with your general contractor or architect.
Architectural Shingle Systems
For Alhambra homeowners who want a premium asphalt roof without tile weight or cost, architectural shingles from GAF, CertainTeed, or Owens Corning are the common choice. These hold up better under the intense San Gabriel Valley sun than three-tab shingles and give you access to manufacturer warranty programs.
Full System Replacements
When we say full replacement, we mean everything: tear-off, decking inspection and repair, underlayment, flashing, and the roof surface. On Alhambra’s older homes, skipping the decking step is the most common mistake we see from other roofers. If the wood is soft, the new roof fails early. We check every sheet.
Trusted Brands We Service in Alhambra
We install and know the technical requirements for seven major roofing brands: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. In Alhambra specifically, we stock common trim, flashing, and underlayment parts for rapid turnaround. For clay tile work in the historic districts, we source Boral tile and authentic mission profiles through established suppliers. Your roof, your material choice. We’ll recommend the best system for your home’s structure and your budget, not the brand that pays us the best kickback.

AfterCommon Roof Replacement Problems We See in Alhambra Homes
- Santa Ana wind damage to original clay tile. The wind events that blow through the San Gabriel Valley in fall and winter regularly dislodge century-old mission tile. Once that tile shifts, the aged underlayment underneath is exposed to the next rain. We find leaks in bedrooms and hallways directly below these displaced tiles.
- Failed decking under original roofs. The 1920s through 1950s homes in Alhambra were built with solid wood sheathing that’s now 70 to 100 years old. Termite damage and decades of small leaks have compromised it. A re-tile without decking repair is a callback waiting to happen.
- Low-slope porch roof water pooling. Porch roofs on Spanish Colonial and Craftsman bungalows have very little pitch. Water sits, finds its way into flashings, and rots the supporting structure from the inside out. This is the most under-diagnosed problem on Alhambra’s older housing stock.
- Historic-preservation mismatches. Homeowners who use a generic roofer to swap concrete tile for original clay often get flagged by the city’s design review. Then they pay twice: once for the wrong roof, and again for removal and replacement with the correct material.
On a 1920s Spanish Colonial just off Main Street in the 91801 core, our crew replaced a low-slope porch roof where original clay barrel tile had slid and cracked after a Santa Ana wind event. We matched the mission tile profile, replaced rotted sheathing, and installed a peel-and-stick ice and water shield under new underlayment before re-laying the tile. The homeowner avoided a historic-preservation violation because we sourced the correct tile profile rather than substituting concrete.

FAQs About Roof Replacement in Alhambra
Yes, if your home is in one of the city’s designated historic districts or subject to preservation review, replacing original clay tile with modern concrete is typically rejected. You’ll need to source matching mission tile profiles. We handle that sourcing before we submit for permits, so you’re not waiting through a review cycle only to get denied. Call (866) 321-6172 and we’ll tell you whether your address is affected.
Sometimes yes, but you need someone who knows what they’re looking at. If the underlayment is still intact and the sheathing is solid, we can re-set and secure the tile. If the decking is compromised, just re-securing tile is a temporary patch that will leak. The honest answer requires an inspection. We offer that as a standalone service with no repair commitment.
Alhambra is an incorporated city, so roof replacements are permitted through the city’s building department. We pull the permits ourselves, and we handle the historic-preservation review process when it applies. You don’t need to coordinate with the city or a third party. Call (866) 321-6172 for a free estimate and we’ll explain the permit path for your specific address.
We treat them as flat roofing systems, not pitched roofs. That means we inspect the drain points, check decking slope, replace rotted framing, and install a membrane system with proper flashing. On tile-topped porch roofs, we re-lay the original or matched tile over a modern underlayment. The goal is keeping the historic look while stopping the leaks for good.
Yes. We source authentic and custom-profiled clay tile from Boral and other suppliers who carry mission profiles matching pre-war Spanish Colonial dimensions. This is the permit-critical step in Alhambra’s historic districts, and it’s where most roofers fall short. You don’t want to be re-roofing twice because you used the wrong profile the first time.
If you’re weighing repair versus replacement, or you need a match for original clay tile, call (866) 321-6172. We’ll inspect, tell you what’s actually wrong, and give you a written estimate. No pressure, no brand steering, just straight answers from a crew that’s done this work all over the San Gabriel Valley.
