Roof Replacement in Pomona — Free Inspection, Itemized Written Quote

Fast, Reliable Roof Replacement Across Pomona

Roof replacement in Pomona costs between $9,800 and $22,000 for a typical 1,500 – 2,200 square foot home, depending on material, tear-off depth, and whether your property falls under City of Pomona or LA County permitting. Most Pomona roofers will quote you a single brand and push you toward whatever earns them the best margin. We don’t work that way. Baycrest Roofing carries seven shingle manufacturers so the right material gets matched to your roof profile, sun exposure, and wind load, not to our inventory.

Why Baycrest Roofing Is Pomona’s Preferred Roof Replacement Company

Pomona’s housing stock is one of the oldest and most varied in the Pomona Valley. We walk roofs near Lincoln Park, Phillips Ranch, and the Wilkerson Tract regularly, and we know what a 1920s Craftsman asks for versus a 1970s stucco ranch. Our crews have re-sheeted skip sheathing, matched clay tile profiles on Spanish Colonial bungalows, and torn off baked-out wood shake across the east side. That local familiarity means our estimates account for the real conditions under the shingles, not just the square footage.

Baycrest Roofing is led by Nolan Cafferty, and we are authorized to install products from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That span matters in a city where a 1930s tile roof, a 1960s shake roof, and a 1990s asphalt roof might all sit on the same block. We inspect first, recommend second. If a repair is honest, we’ll say so. If a replacement is necessary, we’ll price it with a written, fixed quote and no change orders. Serving Pomona since our founding out of Temecula, we’ve built our reputation on the inspection leading the recommendation, every time.

Reroofing in Pomona

Reroofing in Pomona comes up most often on homes where the existing asphalt shingle layer is still structurally sound but nearing the end of its service life. Instead of a full tear-off to the decking, we install a new shingle layer over the old one after a careful inspection confirms the decking, flashing, and ventilation are in good shape. Pomona’s pre-war neighborhoods have a lot of roofs where this works well and saves $2,500 – $4,500 compared to a full replacement. A typical reroof in Pomona runs $6,800 – $11,500 for a single-story ranch, and $9,000 – $16,000 for a larger two-story home.

When Reroofing Makes Sense

If your roof has one layer of asphalt shingles, no decking rot, and no more than two or three soft spots, a reroof can add 15 – 20 years of service at a lower cost. We check attic ventilation, existing underlayment condition, and granule loss before recommending this path.

When a Full Tear-Off Is Required

If the decking is water-stained, the existing roof already has two layers, or you have clay tile or wood shake underneath, you can’t reroof over it. LA County code prohibits more than two layers of asphalt shingles, and many Pomona homes already have an original shake or tile layer buried under a later overlay. We’ll tell you what’s under there before you commit to a number.

Flat Roof Replacement in Pomona

Flat roof replacement in Pomona is a different trade than shingle work, and a lot of general roofers get it wrong. We see this on detached garages, workshop additions, and mid-century flat-roof sections across the city. The usual system is either a multi-ply modified bitumen membrane or a single-ply TPO/PVC sheet, installed over tapered insulation to move water toward drains and scuppers. A flat roof replacement in Pomona typically costs $12 – $18 per square foot, so a 400-square-foot garage roof runs $4,800 – $7,200, and a 1,200-square-foot flat section runs $14,400 – $21,600.

Ponding Water and Drainage

Pomona’s flat roofs fail from ponding water more than anything else. Older flat sections on 1950s and 1960s homes often have sagging decking or undersized drains. We correct slope with tapered insulation or re-frame the decking so water actually leaves the roof, instead of just replacing the membrane and watching it puddle again.

Detached Shops and ADUs

On Pomona acreage and larger lots, detached shops and ADU conversions often have aging flat roofs that were never properly insulated or sloped. We handle those as standalone projects, coordinating material staging and equipment access around septic and well setbacks so the work doesn’t disturb what’s already in the ground.

Trusted Brands We Service in Pomona

We stock and install seven major shingle lines: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For Pomona’s older tile and shake-heavy neighborhoods, Boral clay and concrete tile matters because we can match existing profiles without a full re-tile. For wind-exposed lots near the Pomona Valley’s wind gaps, CertainTeed and GAF architectural shingles with high-wind ratings make sense. We don’t push one brand. We match the material to your roof, not your roof to our inventory. If a Tamko or Atlas shingle fits your budget and your exposure, we’ll tell you exactly why.

Common Roof Replacement Problems We See in Pomona Homes

• Santa Ana wind lift on ridge caps and edge tiles. After a Santa Ana event, we get clusters of calls from the same blocks near the valley’s wind gaps. Ridge caps lift first, then edge tiles crack, and repeated lift-crack cycles let water reach the underlayment without anyone noticing until a ceiling stain appears.
• UV-baked underlayment on older tile roofs. Pomona’s hot, dry summers bake tile underlayment into a brittle sheet. On 60- and 70-year-old homes around Lincoln Park and downtown, the tile looks fine from the street but the underlayment underneath is gone. We’ve pulled up clay tile that lifted off in one solid piece.
• Skip sheathing rot on pre-war Craftsman homes. Many 1910s and 1920s homes in Pomona have original 1×6 skip sheathing instead of solid plywood. When the wood shake or asphalt layer above has leaked, that sheathing rots in strips. Full replacement means re-sheeting sections before the new decking goes down.
• Ponding on detached flat roofs. Older detached garages and workshop additions often have flat or near-flat roofs that pond water because the original lot grading has settled. The ponding accelerates membrane failure and rots the decking underneath. We re-slope and re-drain as part of the replacement.

Pricing for Roof Replacement in Pomona, CA

Pomona Permitting and Acreage: What Changes the Price

Here’s something most generic roof replacement pages skip entirely: Pomona’s pre-war and mid-century homes often sit on unincorporated county islands, so roof replacement permits may come from LA County rather than the City of Pomona, changing inspection timing and requiring county-specific decking and uplift documentation. That’s not a footnote. If your property is on county land, the permit process runs through LA County Building and Safety, and the inspector will look for different things than a city inspector: full re-nailing schedules on decking, specific uplift-rated fasteners in wind zones, and documented underlayment at eaves and valleys. We’ve done enough of both to know which checklist to follow before the first shingle comes off.

On Pomona acreage and open-lot properties, the costs shift again. Long material hauls and tight equipment access add labor hours to tear-off and re-decking, and septic and well setbacks dictate where our staging area can sit and which path the tear-off trailer uses. A lot with a 200-foot driveway and a septic tank 20 feet from the house has different material flow than a standard tract lot. Detached outbuildings and shops often have aging flat roofs where ponding water from poor lot grading accelerates membrane failure and decking rot. We scope all of that during the inspection, not during the job.
