Weston Roof Repair has been reroofing homes throughout the Pomona Valley long enough to know that every street here has its own roof problems. Alan Pruett and our crews don’t hand your job off to subcontractors. The same team that inspects your roof is the team that tears it off and the team that nails the last cap shingle. That matters on Pomona’s narrow lots, where a disorganized crew can block an alley or leave debris in a neighbor’s parkway overnight. We stage tight, we work clean, and we don’t leave until the magnet sweep is done.

Why Weston Roof Repair Is Pomona’s Preferred Roof Replacement Company

Pomona homeowners don’t need a sales pitch. They need a roofer who understands what inland valley heat does to asphalt shingles, what Santa Ana gusts do to ridge caps, and what a 1948 bungalow’s original decking looks like when the underlayment finally fails. That’s the work we do. We inspect first, then recommend. If a repair fixes it, that’s what we’ll tell you. We stock parts and materials locally for Pomona jobs, so we’re not waiting on a supplier in Orange County when your decking is open to the sky.

We’re material-agnostic, which means we work with IKO, Atlas, Tamko, Boral, and three other leading manufacturers. That matters because Pomona’s housing stock spans early-1900s Spanish Colonials, mid-century tracts, and newer builds, and each one needs a different product. We don’t push whatever’s on sale. We tell you what performs on a sun-baked 91766 roof with no shade and a south-facing exposure.

Our Roof Replacement team has handled narrow-lot tear-offs, alley staging, and historic overlay reviews all across Pomona. When you call, you’re talking to the same people who’ll be on your roof.

Reroofing in Pomona

Reroofing in Pomona means tearing off the old shingles, inspecting and usually replacing the decking beneath, installing new underlayment, and laying a full new shingle field over the existing structure, all on a lot that may be 40 feet wide with a detached garage on the rear alley. Most Pomona reroofs run $7,500 to $16,000 depending on square footage, pitch, and whether the decking is salvageable after 60 years of inland heat. Homes in the 91766 and 91767 tracts frequently need partial decking replacement along the eaves and valleys, where thermal cycling has cracked the plywood edges.

When a Reroof Makes Sense

If you’re past the 18-to-22-year mark on an asphalt shingle roof in Pomona, the shingles have likely lost their granular surface to UV and heat. You may see curling at the edges, missing tabs after wind events, or granules collecting in your gutters. The underlayment below is often worse than it looks. A reroof isn’t a repair-and-patch job. It’s a full reset, and it’s the right call when 30 percent or more of the roof is failing.

What the Crew Actually Does

We tear off to the decking, then we look at what’s underneath. In older Pomona homes, that often means replacing sections of dry-rotted or delaminated decking before anything else happens. We install new drip edge, fresh underlayment, and the shingle system you chose, then we flash every penetration properly. On a bungalow off Locust Street in the 91767 tract, we found sun-baked underlayment and a brittle starter strip that nobody could see from the curb. The shingles looked fine. The roof wasn’t.

Flat Roof Replacement in Pomona

Flat roof replacement in Pomona is common on the mid-century commercial strips along Holt and Mission, but it also shows up on residential additions, porch roofs, and the detached garage roofs so many Pomona lots have. A flat roof replacement for a residential structure in Pomona typically runs $6,000 to $12,000 depending on square footage and the system you choose, with modified bitumen and TPO being the most common options. The dry inland climate is hard on flat roof seams, which expand and contract through 40-degree daily temperature swings in summer, opening cracks that aren’t visible until the rain comes.

Detached Garages and Porch Roofs

Flat roofs on detached garages in Pomona’s older tracts often fail before the house roof does. The garage was usually built with cheaper materials, not maintained, and bakes in full sun with no attic ventilation. When you reroof the house, it’s often smart to replace a failing flat garage roof at the same time if the budget allows. We’ll itemize it separately so you see exactly what each structure costs.

Why Seams Fail in Pomona

Pomona’s summer heat pushes attic temperatures above 140 degrees, expanding flat roof membranes all day, then contracting them overnight. That’s 100-plus cycles of movement every month in summer, and it’s what opens seams and flashing over time. Coastal cities don’t get this kind of thermal load. It’s a Pomona-specific failure mode we look for first when evaluating a flat roof.

Trusted Brands We Service in Pomona

We’re authorized to work with IKO, Atlas, Tamko, Boral, and three other major manufacturers, so your Pomona roof gets the right product for the climate, not the one brand we happen to prefer. IKO’s architectural lines hold up well under inland UV, Atlas makes a solid wind-rated shingle for Santa Ana country, and Boral’s tile options matter if you’re trying to match an existing clay tile roof in the older Pomona neighborhoods. We maintain local supplier relationships in the 91766 and 91767 area so materials land on your job site fast, not days after the tear-off starts.

Common Roof Replacement Problems We See in Pomona Homes

• Alley staging without a plan. Detached garages in Pomona’s older tracts sit on rear alleys, and a full tear-off means getting shingle squares, plywood, and a dumpster into that alley without blocking it. We map access before we quote, because dumping the dumpster in a neighbor’s parkway is how jobs go sideways.
• Party-wall and shared-fascia damage on bungalows. Pomona’s early-1900s bungalows are built inches apart. A tear-off on one roof can shake loose fascia or send debris onto the neighbor’s narrow side yard. We notify adjacent neighbors, tarp the gap, and work so that dust stays on our side of the property line.
• Overlay review stalls the permit. Some of Pomona’s older neighborhoods sit in historic or overlay review districts, which can slow a permit after you’ve already paid for materials. We identify review requirements before we file, not after the decking is open.
• Sun-baked underlayment hidden under decent-looking shingles. The UV and heat in the Pomona Valley cooks underlayment even when shingles still hold their granules. That’s why a tear-off here often finds decking and starter strip far worse than the visible roof suggests. We budget for that possibility up front so the quote doesn’t balloon mid-job.
