Hiring a roofing contractor in Pomona usually means working on an older house. About 59 percent of the city's homes were built before 1970, and 1,608 properties sit in the Lincoln Park, Wilton Heights and Hacienda Park historic districts, where a re-roof needs city sign-off before any permit can issue.
Best Top Roofing comes from Camarillo to inspect, repair and replace roofs on Pomona homes. The inspection is free, each problem is photographed, and the written proposal names the shingle, underlayment and vents so you and city staff review the same list.
Citrus-Era Houses and Inland Heat in Pomona
By the 1880s, water and the railroad had made Pomona the western anchor of the citrus belt, and in the 1920s it was called the Queen of the Citrus Belt. SCAG's 2019 profile shows 13.3 percent of today's homes built before 1940 and another 24.2 percent in the 1950s alone.
The city's preservation guide says asphalt or composition shingles are the most common roofing on Pomona homes, and that wood shake has been phased out in Southern California because of fire danger. It also notes that many wood-sided houses were stuccoed over in the 1950s and 1960s, which can trap moisture, so a stain near the eaves might start in the wall rather than the roof.
Heat is the daily stress. NOAA's 1991 to 2020 normals at Pomona/Fairplex count about 70.5 days a year at 90 degrees or more and 10.7 at 100 or more, with rain averaging 14.47 inches, led by February. Fall also brings Santa Ana winds from the northeast.
Lincoln Park, Wilton Heights, Hacienda Park and Phillips Ranch
Lincoln Park, designated in 1998, is Pomona's first and largest residential historic district, with 802 properties between Garey and Towne avenues. Victorian-era homes and early Craftsman bungalows sit near Holt Avenue, giving way to Craftsman and Revival styles farther north.
Wilton Heights, with 534 properties west of Garey, has the most eclectic mix of any district, running from the late 1800s to postwar houses. Hacienda Park's 272 properties include La Casa Primera, one of the city's oldest homes, and the largest group of post-World War II houses in any district. Phillips Ranch, in the hills toward Diamond Bar, has grown since the 1980s and lies outside all three.
Roofing Contractor in Pomona: Services Matched to the House
The five services below reflect what Pomona's housing, heat and preservation rules ask of a roof. Each links to a page with more detail.
Historic District Re-Roofs and the Minor Certificate of Appropriateness
Chapter 3 of Preserving Pomona, approved in October 2022, requires a Minor Certificate of Appropriateness to re-roof a historic building. The new roof must be like for like or in kind, a non-historic roof must give way to the material typical of the home's style, and new vents must be low profile. After staff approval comes a 20-day appeal period, and only then does the permit issue, so our roof replacement schedule counts those days.
Dimensional Asphalt Shingles the City Accepts
The preservation guide treats all dimensional asphalt shingles as acceptable replacements for asphalt roofs, which keeps choices simple on many district homes. We help you pick a color that suits the architecture, then install the shingles over new underlayment with fresh flashing at walls and chimneys. Profiles and wind ratings are covered on our shingle roofing page.
Wood Shake Replacement on Older Homes
If your house still carries wood shake, the city's own guide notes that the material has been phased out regionally because of fire danger. A wood shake roof replacement swaps it for a fire-rated material with a similar texture. On a district home, we first ask staff which material the guidelines expect for that style, since the like-for-like rule can point another way.
Summer Heat Repairs for Sun-Worn Roofs
Seventy-plus days a year at 90 degrees or more take a toll on shingles, sealants and flashing. Common results are curled or cracked shingles, dried-out pipe boots and sealant pulling away at walls. Our roof repair replaces the damaged pieces and reseals the joints, and if wear is widespread we tell you when patching no longer makes sense.
Free Inspections Before You Plan a Re-Roof
A free roof inspection shows whether you face a repair or a full replacement, and for a district home the photos help when you talk with city staff. We check visible decking, flashing, vents, attic airflow and gutters. You keep the photos and written notes whether or not you hire us.
Pomona Building Permits and Historic Preservation Rules
The Building and Safety Division at City Hall, 505 S. Garey Avenue, takes walk-ins Monday through Thursday and accepts electronic plans by email. City offices close on Fridays, and the division does not inspect on Fridays, weekends or city holidays, so Pomona jobs run on a four-day inspection week.
Under Section .5809-13 of the zoning ordinance, exterior alterations in the historic districts need a Minor or Major Certificate of Appropriateness unless the property is exempt. Work outside the standards goes to a Major COA and a Historic Preservation Commission hearing.
Only 24 acres of Pomona are mapped Very High on the 2025 recommendations, but 1,682 acres are High. On a mapped parcel, the Wildland-Urban Interface Code (Title 24, Part 7), successor since January 1, 2026 to CBC Chapter 7A, requires at least Class A roofing in repairs.
