Fast, Reliable Roof Replacement Across Bloomington
Roof replacement in Bloomington typically runs between $9,800 and $22,500 for a standard single-story home, depending on the material and how much decking the County makes us replace once we open it up. Most Bloomington jobs take 2 to 4 weeks from permit filing to final inspection, with the County plan check eating the first chunk of that. We know every wrinkle of that timeline because we’ve pulled permits in San Bernardino County hundreds of times and we’ve re-roofed enough Bloomington homes to know what’s behind the stucco. If your roof is failing, call (866) 942-0875 and we’ll give you an honest assessment before you spend a dime.
Why Oakmont Roof Repair Is Bloomington’s Preferred Roof Replacement Company
Bloomington homeowners don’t have a city hall to walk into. Every permit goes through San Bernardino County, and the County’s plan check process for roof replacement is strict about documentation. That’s where we step in. We handle the submittal packet ourselves: dimensioned drawings of every roof plane, including patio covers and detached garages that tie into the main house, so the permit isn’t rejected for missing detail and your job doesn’t stall in review. The homeowners who call us often tell us they already lost weeks with another contractor who only submitted the primary structure. We file it right the first time.
Our Bloomington customers keep calling Noel Fierro and the Oakmont crew back because we show up when we say we will and we don’t leave a roof torn open while a plan checker catches up on paperwork. We schedule the tear-off to begin only after the permit is issued. That means your home is never sitting exposed to a Santa Ana wind event with half the roof peeled back. Bloomington’s older homes have enough quirks without adding a weather-soaked interior to the list.
We’re a roofing company, not a general contractor who happens to do roofs. Our crews think in shingle courses, flashing details, and wind uplift patterns, and we carry seven major brand lines so the material recommendation matches what your home actually needs, not what we happen to have sitting in a warehouse.
Styles & brands we work with
Flat Roof Replacement in Bloomington
Flat Roof Replacement in Bloomington runs $7,400 to $14,800 for most detached garages, patio structures, and the flat sections common on 1960s and 1970s additions. The first sentence you need is this: if your flat roof is over 15 years old and you see blisters, cracking, or ponding water after any decent rain, it’s time to replace it, not patch it. Bloomington’s heat bakes the top coat on modified bitumen and built-up roofs until it turns brittle, then the first cold snap opens hairline cracks that water follows straight into your ceiling.
How We Replace a Bloomington Flat Roof
We strip the old membrane to the wood. A lot of Bloomington flat roofs hide rotted decking underneath, especially on owner-built patio covers where the pitch wasn’t set steep enough to shed water. We replace any soft or delaminated decking, re-slope where the framing allows, and install a new membrane system from Owens Corning or CertainTeed with sealed seams and proper edge flashing.
Why Bloomington Flat Roofs Fail Early
The Inland Empire sun is relentless. Between the UV load and the wind-driven dust off the Cajon Pass, flat roofing material in Bloomington loses flexibility years before the manufacturer’s rated lifespan. We account for that by spec’ing white or reflective cap sheets that cut surface temperature and slow the heat damage.
Roof Installation in Bloomington
Roof Installation in Bloomington, whether it’s new construction or a full tear-off on an existing home, runs $11,200 to $26,900 depending on the roof’s footprint, the slope complexity, and whether County inspectors flag framing or sheathing that has to come up to current code. Bloomington’s housing stock is mostly 1950s through 1970s single-story stucco ranches, and many of them have never had a full roof replacement. That means we’re often the first crew to see what’s under the original shingles in fifty years.
What a Bloomington Tear-Off Actually Involves
We pull the old shingles and felt, then inspect the decking board by board. On homes near the Fontana line, sun rot and decades of trapped moisture have softened more sheathing than homeowners expect. We replace it instead of nailing over it, because no shingle will save a roof whose deck is spongy. Then we lay new underlayment, ice and water shield in the valleys and eaves, and nail the shingles to the manufacturer’s high-wind pattern.
When New Construction Makes Sense
For ADUs, detached garages, and the occasional full home addition in the 92316 area, we work from your approved plans. The County requires the roof assembly to meet current California energy code, which usually means a cool-roof shingle or a radiant barrier. We’ll flag that during the estimate so your budget doesn’t get surprised mid-job.
Trusted Brands We Service in Bloomington
Oakmont Roof Repair installs and services roofing systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Seven major brands, one trusted installer. That range matters in Bloomington because the right material for a sun-baked west-facing slope is not the same as the right material for a shaded backyard patio cover. We don’t push a single manufacturer’s line. If your home needs a premium architectural shingle with a strong wind warranty, we’ll show you GAF Timberline HDZ or CertainTeed Landmark. If the budget is tighter and the roof pitch is simple, we’ll recommend a value line from IKO or Atlas and be straight with you about the tradeoffs. We keep materials for these brands moving through our Inland Empire suppliers, so Bloomington jobs don’t wait on shipping.

AfterCommon Roof Replacement Problems We See in Bloomington Homes
These are the failures we walk into week after week in the 92316 neighborhoods, from the blocks off Valley Boulevard to the quieter streets up toward the Santa Ana River basin:
- Santa Ana wind damage on exposed slopes. A direct gust off the Cajon Pass will peel ridge caps and whole tab sections off a roof that’s been baked stiff by years of 100°F summers. The shingles don’t flex anymore, so they tear instead of bending.
- Owner-built additions that tie into the main roof at bad angles. Decades ago, someone enclosed a patio or slapped a flat roof onto a detached garage without a plan check. The valley where the two slopes meet was sealed with tar and never flashed with metal. The first heavy winter rain finds it.
- Layer-over-layer tear-offs. Bloomington homes often have two or three layers of old shingles because past owners kept reroofing over the existing roof to save money. County code caps it at two layers for a reason: the deck can’t handle the weight or the heat. We strip it all to the wood.
- Rotted eave and rake edges from snow-level drainage. It never snows here, but the occasional heavy winter downpour overwhelms old drip edge and rots the fascia and the first course of decking. When we lift the old shingles, the outer 12 inches of sheathing are often mush.

FAQs About Roof Replacement in Bloomington
San Bernardino County issues the permit, because Bloomington is unincorporated and has no city building department. You file through the County’s Land Use Services division, not a local city hall. We prepare and submit the full packet for you, including dimensioned drawings that account for every roof plane tied into the main house.
County plan check typically adds 2 to 4 weeks before work can start. The review is slower when the submittal packet is incomplete, which happens often on Bloomington homes where owner-built additions and detached garages have to be reconciled under one roof plan. We front-load that documentation so the clock doesn’t stall. Call (866) 942-0875 and we’ll walk you through the timeline for your specific house.
Class A fire-rated asphalt shingles, architectural shingles, and flat-roof membranes from major manufacturers all get approved when the submittal meets current California energy code. Cool-roof shingles are often required for new construction and some additions. We carry GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so we can match the County’s requirement and your budget without compromise.
Yes. The County plan check will require drawings that show every abutting roof plane, including the patio cover and detached structures, and we’ll reflashing those transitions with proper metal and ice and water shield. We re-decked just this situation on a 1960s stucco ranch off Valley Boulevard near the Fontana line, where the detached garage roof tied into the house at an angle that had never been flashed correctly. The fix produced one continuous roof plane.
We nail to the manufacturer’s high-wind pattern, which means six nails per shingle, starter strip at every eave, and reinforced ridge caps. On Bloomington homes where the west-facing slope catches the full force of a Cajon Pass gust, we also upgrade the underlayment and verify the deck is sound before nailing. That’s the difference between a roof that survives the next wind event and one that sheds shingles in the first year. Call (866) 942-0875 for a free estimate.
