Baldwin Park mixes single-family houses with apartment buildings and small commercial property, and we roof all three.
Tell us what covers your roof today and where water shows up inside. A steep shingle roof and a low-slope roof fail in different ways. Each one needs its own materials and flashing details.

The roof work we do in Baldwin Park
We repair leaks, tear off worn coverings, replace roofs down to the deck, and relay tile over new underlayment. Flat and low-slope sections receive torch-down modified bitumen. Every job starts with a count of the layers already on your roof.
On a tear-off we strip the entire roof down to bare wood decking. Rot in the decking becomes visible at that point. We replace the bad boards before any new material goes over them.
New underlayment goes down before the covering goes back on.
One slipped tile, a cracked vent boot, or a single leaking flashing joint is a repair call. We handle those as readily as full replacements.
Shingle and tile roofs
On pitched roofs we install asphalt shingle, and we also lift and relay existing tile. The tile itself usually outlasts the underlayment sheet installed beneath it. So a tile roof can need work under a covering that still looks sound.
We lift the tile off in sections and remove the failed underlayment. Then we repair the decking and stack your original tile back on. Our tile roofing page describes that project in greater detail.
Flat roofs on additions and commercial buildings
Plenty of houses here carry a flat porch, patio, or addition roof. Those sections require a low-slope system, so we install torch-down modified bitumen. We heat weld the membrane in place, and the fused laps hold on a roof that drains slowly.
Commercial buildings receive the same system, and our commercial roofing page describes that work. Our flat roofing page covers low slope roofing in full detail.
Your roof has to move its own rain into gutters and away from the walls. We scope that path first, then build the flashing and valleys for the winter storms. We rebuild the flashing at walls, chimneys, and valleys, because those junctions leak first.
What sets your price
Roof area sets the price, and the floor area of your house does not show that number. We measure the roof itself, then check pitch, stories, and the coverings already on the deck. Those measurements shape the quote, so we never guess at them.
Rot under the covering moves the number. Tile that must come off and return afterward moves it again. A mapped fire hazard zone can change the materials we quote.
Permits and current code
A roofing permit here comes from the city of Baldwin Park, and we help you pull one when required. The office that reviews the permit sets the fee and the schedule for your job. Ask us about it while we scope the roof.
We take Baldwin Park calls in Census ZIP Code Tabulation Areas 91706 and 91732. We work the same way inside ZCTAs 91746 and 91790, from a single leak to a full tear-off.
California's building code, Title 24, advanced to a new edition on January 1, 2026. The state code page lists the editions now in force, and your city can amend them locally.
Fire zone mapping can change the covering itself. Inside a mapped High or Very High Fire Hazard Severity Zone, a new roof must reach Class A. That designation is the highest fire rating a roof assembly can earn.
Outside those mapped zones, the state requires a lower rating.
Nearby areas we cover
We also roof Irwindale, West Puente Valley, and Avocado Heights, and we quote those roofs the same way. Each of those addresses answers to its own building department, and permit rules shift from city to city. Our complete list appears on the service areas page.

Call us at (626) 323-8814 about a leak, a failing flat roof, or a replacement you are planning. You can also submit the contact form and describe the building in your own words. Either way the quote costs nothing, and it spells out the work we propose.
Houses, apartment buildings, and small commercial property each price differently here. Roof area, access, and any low-slope sections all move the number. Call (626) 323-8814 and tell us which one you own, so the three answers below fit your own building.
How much should a 1500 sq ft roof cost?
A house measured at 1,500 square feet does not have 1,500 square feet of roof. We price from the roof area we measure, counted in squares of one hundred square feet. Stories, pitch, existing layers, rot, and tile handling all move the number from there.
What is the 25% rule for roofing?
California's state code sets no 25 percent roofing rule. Inside a mapped High or Very High Fire Hazard Severity Zone, a different threshold applies. A job that replaces half your covering or more within a year must meet new construction requirements.
What is the average cost of replacing a roof in California?
A California average blends new tract houses with older buildings that carry several coverings. We price your Baldwin Park roof from its own area, pitch, stories, and deck condition. We put that measured scope in writing beside the number, so nothing stays hidden.
