Roof Replacement in Pomona — Written Price, Workmanship Warranty

Fast, Reliable Roof Replacement Across Pomona

Roof replacement in Pomona typically runs $8,500 to $16,500 for a standard asphalt shingle tear-off and re-roof on a 1,200 to 1,800 square foot home, and most jobs take three to five working days once materials land. The bigger variable in Pomona isn’t brand or labor rate – it’s what we find when the old roof comes off. Pre-1950s homes in the 91766 and 91767 ZIP codes regularly sit on 1×4 skip sheathing instead of solid plywood decking, and that one condition changes everything about how we prep, fasten, and price the job.

We’re Van Nuys Roofing Co, and we handle Roof Replacement across Pomona with a simple rule: inspect first, recommend second. If you’re weighing repair against replacement, call (866) 321-6172 and we’ll give you a straight answer about which one actually makes sense for your roof.

Why Van Nuys Roofing Co Is Pomona’s Preferred Roof Replacement Company

Pomona homeowners call us because we don’t push a single brand and we don’t pretend every roof needs the same fix. Our crews know the difference between a 1920s Craftsman bungalow off Garey Avenue and a 1960s tract home near Fairplex, and we price the work accordingly. That local knowledge matters when the real cost driver is hiding under the shingles.

We work with seven major material manufacturers – GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means manufacturer warranty eligibility is available across multiple product lines, not just the one brand a single-brand shop happens to stock. Our installers know the technical installation requirements for each, so you get an honest recommendation based on your roof’s exposure and your budget, not a supplier incentive.

Led by Rick Dominguez, our Pomona crews handle full tear-offs, flat roof sections, decking replacement, and new construction roofing in-house. No referrals, no subcontractor roulette. One crew, one contract, and a written line-item price before we start. Rick’s rule is the same on every Pomona job: anything we find once the roof is open gets priced in writing and approved by you before we spend a dime on it.

Flat Roof Replacement in Pomona

Flat Roof Replacement in Pomona is common on the post-war tract homes and garage additions scattered through the 91766 and 91767 ZIP codes, where low-slope sections meet pitched roofs and collect more debris and heat than the main roof plane. A flat roof section under 400 square feet on a Pomona garage or addition typically runs $3,200 to $5,800 for full tear-off, new underlayment, and either modified bitumen or TPO membrane, depending on access and drainage condition. Larger flat roof areas on commercial-style residential builds can push past $9,000.

Flat sections on pitched roofs

Many Pomona homes built between 1920 and 1960 have a flat section over a porch, a back addition, or a converted garage. These areas fail faster than the pitched shingle roof because water pools longer and the membrane takes direct UV sun all day. We inspect the transition flashing between the flat membrane and the shingle roof closely – that seam is where most leaks start on older Pomona homes.

When a patch won’t cut it

If the membrane has blistered, the decking below feels spongy, or you’re seeing water stains on the ceiling under a flat section, replacement usually beats another patch. We’ll tell you straight if a repair buys you two years or if you’re throwing money at a membrane that’s already done. The estimate is free either way.

Roof Installation in Pomona

Roof Installation in Pomona covers two situations: full replacements on existing homes and complete roof systems on new construction or additions. A new architectural shingle roof on a standard Pomona ranch or bungalow runs $8,500 to $14,000, including tear-off, decking repair, underlayment, new flashing, and ridge ventilation. Full tear-offs with skip sheathing re-nailing typically add $1,200 to $2,800 depending on the board condition and how much sistering the decking needs.

Architectural shingles for wind exposure

Pomona’s Santa Ana wind events hit west-facing slopes hard, and many older homes still have the original three-tab shingles with their weak nailing pattern. Architectural shingles – the laminated style from GAF, CertainTeed, or Owens Corning – carry higher wind ratings and hold their seals better when the wind shifts direction. We upgrade the nailing pattern and starter strip on every Pomona install because the wind here doesn’t care what the original spec said.

Decking replacement on older homes

If the home pre-dates 1960, expect open skip sheathing under the old shingles. We don’t lay underlayment over split or loose boards. The decking gets re-nailed, overlaid with CDX plywood where the spacing doesn’t meet modern fastener requirements, and only then do we install the roof system. You’ll see that scope item as a line in the contract before we start, not as a surprise after.

Common Roof Replacement Problems We See in Pomona Homes

• Skip sheathing that splits under re-nailing. Pre-1950s bungalows in 91766 and 91767 often have 1×4 boards spaced apart instead of solid decking. When we tear off old shingles, those boards are frequently split, cupped, or pulling loose, leaving nothing solid to fasten new underlayment to. We re-nail, sister, or overlay before any new material goes down.
• West-facing slopes losing ridge caps after Santa Ana events. Homes in the 91767 flats take wind lift on the west exposure, and we regularly find lifted shingles and missing ridge caps after a big wind event. The original fastening pattern was never designed for repeated Santa Ana cycles, so we upgrade nailing and add a full starter strip on every west slope we re-roof.
• Dry rot and failed flashing under aging composition shingles. Hot inland summers bake Pomona roofs, and UV degradation weakens the flashing seals around vents, skylights, and valleys long before the shingles look bad. Tear-off exposes rot at the fascia and rafter tails on a lot of older Pomona homes, and that needs to be cut out and sistered before new metal goes in.
• Original clay tile on early Craftsman homes hitting end of life. Some Pomona Craftsman-style houses still carry original clay tile, and while the tile itself lasts, the underlayment beneath it doesn’t. Re-roofing these means removing tile carefully, replacing the underlayment and battens, and resetting or replacing the tiles. We handle this in-house – you don’t need a separate tile specialist.
