Roofing Contractor in Bloomington, CA, for Older Homes and Every Roof on the Lot
About half of Bloomington’s homes were built before 1975, and part of the community is large-lot rural estates with room for a workshop or animals out back. A reroof with a roofing contractor in Bloomington, CA, often covers more than the house, because garages, workshops, and animal shelters have roofs too.

Bloomington is unincorporated: about 3,200 acres along I-10, bounded by Fontana, Rialto, and Riverside County, and the County’s largest and most developed unincorporated community. Overhead Roofing handles roof repair and reroofing projects in Bloomington, CA, and schedules inspection visits in advance.
Bloomington roof replacement on houses from the 1950s to the 1970s
Suburban subdivisions began replacing Bloomington’s farms in the 1950s, and the median home dates to 1975 (American Community Survey, 2020 to 2024). The County describes today’s housing as a mix of large-lot rural estate homes, suburban single-family subdivisions, a few rental apartments, and several mobile home parks.
A house from the 1950s to the 1970s has usually been reroofed before, sometimes with new shingles laid over old ones, so the next job is often its first full tear-off. Board decking or older plywood with soft spots at the eaves, valleys, and old vent openings is repaired before new underlayment goes down. Attic ventilation gets checked while the roof is open, since older houses often have too few vents or vents that were covered over, and flashing at chimneys, walls, and pipes is replaced, not reused.
Bloomington is in Climate Zone 10, and a County reroof permit comes with a Cool Roof Form. Replace more than half the roof on a house and a pitched roof needs a CRRC-rated product, while a low-slope section needs cool roof compliance. The permit steps are in our San Bernardino County roofing guide, under County permit rules for Bloomington.
Detached roofs on Bloomington's rural-estate lots
The County’s Additional Agriculture overlay, the AA in a zone such as RS-1-AA, is meant to create, preserve, and improve areas for small- and medium-scale agriculture and allows animal keeping; land in the 213-acre Bloomington Business Park plan area carried RS-1-AA zoning before that plan. On Bloomington’s large rural-estate lots, the house often shares the property with detached garages, workshops, carports, and animal shelters.
Those roofs often differ from the house. A workshop may have a low-slope roof that needs a flat roof system, an animal shelter a metal panel roof, and an older garage shingles over lighter framing than the house has. Each structure gets its own repair-or-replace answer and its own line in the written estimate, so you can reroof the house now and the shop later, or do everything as one project.
The County’s reroof permit page says a roof covered in slate, clay, cement, or asbestos tile can’t be re-covered, so an old tile roof on a garage comes off before new roofing goes on, the same as on the house.
How a roofing contractor in Bloomington, CA, weighs repair against replacement
Owners live in 69.3% of Bloomington’s occupied homes (ACS 2020 to 2024), and for an owner who plans to stay, repair versus replacement comes down to how long the fix has to last. A repair fits when the damage is local: a leak at one pipe flashing or chimney, a few broken tiles, or wind-lifted shingles on one slope, with sound decking around it. Replacement fits better when the roof has more than one layer, leaks in several places, or has soft decking across a whole section.
Bloomington households average 4.52 people, against 3.34 countywide, so a reroof here usually happens with a full house at home. We tear off only as much roof as we can cover with underlayment by the end of the workday, so the house is closed up each night.

Bloomington, CA questions about detached buildings, old roofs, and fire maps
Does the County's ice barrier form apply to my garage or animal shelter?
Not if the building has no conditioned floor area. The County’s Ice Barrier Certification, filed with a reroof permit along with a Smoke and Carbon Monoxide Alarm Certificate and a Cool Roof Form, exempts detached accessory structures without conditioned space. The form itself applies where ice has a history of forming along the eaves, so ask County Building and Safety whether it applies to your address at all.
Can a new roof go over the old one on my Bloomington house?
Not over slate, clay, cement, or asbestos tile, and not over water-soaked or deteriorated roofing; the County requires a tear-off in those cases. The County’s sentence on how many layers are allowed is unclearly worded, so confirm the limit with Building and Safety. On a 1950s to 1970s house that already carries an overlay, a full tear-off is usually the better job.
Is Bloomington in a Very High fire hazard zone?
Not at the points checked. On CAL FIRE’s 2025 local responsibility area map, central and south Bloomington are NonWildland, and the nearest Very High area checked lies just south across the line in Fontana’s Jurupa Hills. The Board of Supervisors, acting for the County Fire Protection District, adopted the 2025 zones as Ordinance No. 4489 on June 10, 2025. Check your parcel before choosing a roof covering.
What wind and rain numbers does the County use for Bloomington roofs?
County Information Bulletin IB-0003, updated January 1, 2026, sets a minimum wind Exposure Category C throughout San Bernardino County and sizes roof drains and gutters for 2.5 inches of rain per hour, the 100-year rate, unless a site-specific NOAA value is used. That matters most on large low-slope shop and shelter roofs, where drains and scuppers have to move that water without ponding.
