Fast, Reliable Roof Replacement Across Glendora
Roof replacement in Glendora typically runs $18,500 – $42,000 for a full tear-off and re-roof on a standard mid-century ranch, with hillside custom homes running higher due to steeper pitches, tile, and complex roof lines. Most Glendora replacements take five to nine working days once materials land, though the tear-off itself often reveals conditions no one could see from the ground. We work across 91740 and 91741 regularly, and we know what these foothill homes hide under their old coverings. Call (833) 467-4846 to schedule a roof inspection, and we’ll tell you what your roof actually needs before we quote a single number.
Why Tilecraft Roofing Is Glendora’s Preferred Roof Replacement Company
Glendora homeowners call us because we look before we quote. That means an inspection first, a written scope second, and a replacement recommendation only when repair genuinely won’t hold. We work with seven major roofing manufacturers, including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That breadth matters here because Glendora’s homes split into two very different roofing challenges: the mid-century tracts off Sierra Madre Ave and the foothill customs further up. One crew, one contract, and the same standards on both.
We’ve torn off enough original wood-shake and cracked asphalt in Glendora to know that the real work often starts after the old roof comes off. That’s where our process differs from a replacement-first shop. We photograph what we find, price it line-item, and get your written approval before we add a single square of work. Ruben Castellano, owner at Tilecraft Roofing, has built the company on that plain honesty. You’ll know what you’re paying for, and you’ll know why.
Our suppliers stock materials in the San Gabriel Valley, so lead times to Glendora stay short. When a Santa Ana event tears through and your neighbor’s roof ends up in a canyon, we can respond without a week of waiting on material delivery. Same for flat roof membranes on the hillside homes where drainage and flashing get tested every winter.
Styles & brands we work with






Flat Roof Replacement in Glendora
Flat Roof Replacement in Glendora generally runs $12,000 – $28,000 depending on square footage, deck condition, and whether we’re tearing off built-up layers or going over a concrete deck on a hillside custom. Homes in the foothills often have flat sections over patios, garages, or mid-level additions, and those sections age differently than pitched roof fields. The San Gabriel sun hits them directly all summer, and when rain comes, every lap and seam has to work or water finds the sheathing underneath.
The job starts with a close look at the existing membrane, penetrations, and drainage. On older Glendora homes, we frequently find failed torch-down or peeling elastomeric coatings that someone armored over instead of replacing. A new flat roof, done right, involves tearing off failed layers, addressing any wet or damaged decking, and installing a membrane matched to the exposure and the roof’s use. We then test drainage before we call it done.
Built-Up and Modified Membranes
For most Glendora flat sections, we install modified bitumen or single-ply systems from manufacturers in our portfolio. The choice depends on how much direct afternoon sun the section takes and whether the flat area sees foot traffic for maintenance access. A hillside home with an exposed southern flat section needs different material than a shaded garage pop-out.
When Flat Roof Repair Isn’t Enough
If we find wet insulation, rotted plywood, or a membrane that’s already been patched in three places, replacement is the honest recommendation. Repairing a failed flat roof repeatedly costs more than doing it once, and a leak over a finished room below is expensive in a different way. We’ll show you photos of what we found, then give you a scope and a number.
Roof Installation in Glendora
Roof Installation in Glendora covers both new construction and full replacement on existing homes, and runs $22,000 – $65,000 for a complete install on a typical Glendora home. New construction in the foothills runs higher because of tile, steeper slopes, and access constraints. Replacement on a 1960s ranch off Sierra Madre Ave is a different animal, and the final number depends heavily on what the tear-off exposes underneath.
Every installation starts with a roof that’s properly decked, flashed, and dried in before the finish material goes on. That’s not a slogan. It’s the difference between a roof that lasts twenty-five years and one that fails in eight. We set drip edge, run ice and water shield through valleys and around penetrations, and install the covering to the manufacturer’s fastening pattern, not whatever’s fastest.
Asphalt Shingle Installation
For most Glendora homes, architectural asphalt shingles from GAF, CertainTeed, IKO, or Atlas give the best balance of cost, longevity, and uplift resistance. The Santa Ana wind rating matters here. We fasten shingles above the required starter strip at the nailing schedule the uplift exposure demands, because a 60 mph gust through the canyons will find every under-driven nail on the roof.
Tile and Specialty Installation
Glendora’s foothill homes often carry tile, and our Boral partnership means we can match clay and concrete profiles that other contractors won’t touch. Tile over a steep, multi-valley hillside roof is precision work. The underlayment is doing the waterproofing; the tile is doing the weathering. Both have to be right, and we install them in that order.
Trusted Brands We Service in Glendora
Tilecraft Roofing installs and services products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven leading brands, one crew. That lets us recommend the right material for your specific roof rather than pushing whatever we happen to stock. For a North Glendora ranch taking full afternoon sun, we may suggest Atlas for its heat-reflective granules tied directly to San Gabriel UV exposure. For a hillside custom that calls for clay tile aesthetics, we quote Boral profiles that match the neighborhood. We keep common profiles and materials moving through the valley, so your replacement doesn’t stall waiting on a truck from further out.
Common Roof Replacement Problems We See in Glendora Homes
- Original wood-shake over spaced skip sheathing. In the 1950s and 60s tracts off Sierra Madre Ave and nearby foothill streets, the original shake was often laid over 1x boards with gaps between them. The moment we tear it off, the inspector requires a code-compliant re-deck, which is a legitimate change to scope and price.
- Dried and wind-cracked shingles. Decades of intense San Gabriel sun embrittle asphalt and shake alike, and the Santa Ana winds do the rest. We routinely see roofs that look intact from the ground but are ready to tear under the first 60 mph gust.
- Failed underlayment on hillside tile roofs. Tile can hide worn-out felt and flashing for years. Complex roof lines with multiple valleys and skylights concentrate water, and when the underlayment goes, the leak can travel far from where the damage actually is.
- Missing or rusted flashing at penetrations. Older Glendora homes often carry original flashing around chimneys, vents, and pipe jacks. Once the roof is open, we replace all of it, because new shingles over old flashing is just a future leak waiting.

FAQs About Roof Replacement in Glendora
Because the original 1x skip sheathing under many 1950s and 60s Glendora roofs doesn’t meet current code, and once the old covering is off, the inspector will require solid decking before new roofing goes on. We write a re-deck allowance into every bid so you’re not blindsided, and if we find bad sheathing, you’ll approve the exact added cost in writing before we proceed. Call (833) 467-4846 for an inspection that maps this out upfront.
Santa Ana winds can exceed 60 mph through the foothill canyons, so we install shingles with higher wind-uplift ratings and fasten them on the uplift pattern above the required starter strip. For most Glendora homes, we recommend architectural shingles from GAF, CertainTeed, or Atlas with documented wind ratings suited to the exposure.
A square is 100 square feet of roof area, and every material quantity, tear-off labor, and fastening count on your bid is calculated in squares. When a bid says 28 squares, that’s 2,800 square feet of roof surface. We quote by square because that’s how manufacturers and roofing suppliers meter materials, and it lets you compare line items honestly.
Yes. Foothill flat sections take more direct afternoon sun and often drain toward steeper slopes, so we install membranes matched to that UV load and verify drainage paths that don’t dump water against a hillside retaining wall or a lower roof. We see this routinely on custom homes where a flat section over a garage or mid-level addition ties into a pitched main roof.
The two most common are solid re-deck replacement and the addition of ice and water shield in valleys and around penetrations, both required once the old covering exposes what’s underneath. Some mid-century homes also need fascia and drip edge replacement where decades of Santa Ana exposure have split the original wood. We price all of these as written change orders before we lay a single square.
