GAF Construction in Bloomington, CA | Stallion Contractors
We provide independent GAF roofing and construction service across Bloomington, from full Timberline HDZ replacements on 1950s ranch homes to targeted repairs on detached garages off Valley Blvd. The one thing that separates our GAF work here: every project runs through San Bernardino County Land Use Services, not a city building department, and we handle that sequencing so your roof doesn’t stall in plan check. Call (855) 600-3192 for a free estimate on any GAF roof, repair or replacement, anywhere in the 92316 ZIP.
Why Bloomington Residents Choose Us for GAF Service
We’ve pulled apart and rebuilt enough GAF roofs across Bloomington to know exactly how Timberline shingles behave after a decade of 100°F summers and Santa Ana dust. We’re an independent GAF service provider, not a factory-authorized dealer, which means our material calls follow what your roof deck actually needs, not what a showroom pushes. Ruben Montoya grew up in Colton, not far from Pepper Avenue, and spent years on Inland Empire job sites before running our crews, so when we open up a Bloomington roof, we know what two decades of valley heat does to felt, sheathing, and seal strips. If you want a full-scope contractor who also handles kitchens, fencing, and ADUs, see our GAF sales & service page. For Bloomington specifically, we’re the crew that shows up knowing the county permit path before we lift a shingle.

Common GAF Construction Problems We Solve in Bloomington
Bloomington’s housing stock is mostly 1950s through 1970s single-story stucco and ranch homes on cinder-block foundations, and those roofs carry their own signature failures. Here’s what we see most:
- Granule loss and seal-strip re-sealing failures on Timberline HDZ: After enough summers past 100°F, the asphalt strip that bonds overlapping shingle layers can cook loose. You’ll see bald patches where granules have washed into gutters and tabs that lift in the first Santa Ana gust. We repair isolated damage when the deck is sound; when granule loss runs wall to wall, a full replacement is the honest quote.
- Wind-lifted tabs on aged 3-tab Royal Sovereign: Older Bloomington tract homes often still have original GAF Royal Sovereign. Those shingles get brittle fast in valley heat, and the rake edge is always the first to crease and tear. We replace lifted tabs before the next wind event turns them into leaks over your living room.
- Premature aging on unpermitted add-ons and detached garages: A lot of Bloomington’s detached garages and room additions were built with a single layer of felt over spaced sheathing. Under direct summer sun, that felt dries out and the shingles above it curl. The fix usually means re-decking that section before new felt goes down, and we quote it that way up front.
- Leaks at valleys, pipe boots, and step flashing over garage conversions: Non-permitted garage conversions and room additions often have hand-cut transitions where the old roof meets the new. Valley metal folds wrong, pipe boots lift, step flashing gaps. These leaks show up first because the original tie-in was never inspected. We trace the water path back to the transition and fix it at the source.
- Ridge venting failures on ranch-style homes: Bloomington ranch houses with low-slope gable roofs depend on Cobra ridge vent to dump attic heat. When that vent was installed without Pro-Start starter strip or with nailing schedule mistakes, the vent warps and the attic becomes an oven. We re-set venting with proper overlap and fastening so the roof can breathe in August.
GAF Service in Bloomington: What Local Conditions Mean for Your Equipment
Because Bloomington is unincorporated, any GAF roof replacement runs through San Bernardino County Land Use Services rather than a city building department. That changes more than the address on your permit. County plan checks and inspections follow their own sequencing, and here’s the part that catches people: if your Bloomington house has an unpermitted garage conversion, room addition, or second unit, the county’s as-built discovery process flags it before your tear-off. You can’t just re-roof over a transition that was never permitted. Our crews have worked enough Bloomington properties off Valley Blvd — plus GAF service in Fontana and nearby areas — to know exactly what triggers a correction notice and what doesn’t. We sort the permit path first, get the as-built drawn, then schedule the roof work so you’re not paying for materials sitting in a driveway while the county reviews. That’s the Bloomington difference most Inland Empire roofers never touch.
GAF Models & Products We Service in Bloomington
We work on the full residential GAF line that Bloomington homes actually carry. GAF Timberline HDZ architectural shingles are what we install on most full replacements, paired with Cobra ridge vent, Pro-Start starter strip, and Tiger Paw or FeltBuster underlayment depending on deck condition. GAF Timberline Natural Shadow and Ultra show up on newer additions and upgrades; GAF Royal Sovereign 3-tab is the original roof on a lot of 1960s and 1970s ranch homes. On repairs, we use genuine GAF shingles and Cobra venting where the deck is sound and the roof is worth keeping. Where budget drives it, we’ll switch to quality aftermarket underlayment or flashing, but we won’t spec it as a false economy on a wind-stressed Bloomington roof.

AfterGAF Service Pricing in Bloomington
Roof pricing in Bloomington follows the same realities as the rest of the western San Bernardino Valley, with one local twist: county permit fees and the occasional as-built correction add a line item that city-permitted jobs don’t carry. Here are the ranges we quote from:
| Service | Typical Bloomington Range |
|---|---|
| Roof Replacement | $8,000 – $20,000 |
| Roof Repair | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
What moves the number: deck condition once we open it up, square footage, slope, whether you’re on spaced or solid sheathing, and whether the county requires an as-built correction on an attached conversion. Every free estimate includes a written line-item quote with the permit path spelled out. Good work doesn’t need a sales pitch, it needs the right materials and someone who knows what they’re doing. Call (855) 600-3192 and we’ll walk the roof with you.

FAQs – GAF Construction in Bloomington
If isolated tabs are lifting at the rake or ridge and the roof deck is still solid, we repair with matched GAF shingles and proper nailing, which typically runs $400 to $1,800. If granule loss is widespread across the field and tabs are creasing everywhere, replacement is the honest call, typically $8,000 to $20,000 depending on square footage and deck condition. Call (855) 600-3192 and we’ll tell you which side of the line your roof falls on after we look at it.
Yes. Bloomington is unincorporated San Bernardino County, so roof replacements run through San Bernardino County Land Use Services, not a city building department. We handle plan check, inspections, and any as-built correction that comes up, which is common on older Bloomington homes with unpermitted garage conversions or room additions.
They’re the right shingle for this climate when installed correctly. Timberline HDZ carries a wind rating that handles inland Santa Ana gusts, and its seal strip is designed to re-seal after heat, but proper starter strip, felt, and ridge vent matter just as much as the shingle itself. We install the full system, not just the top layer, so your roof sheds heat and wind the way GAF intends — the same standard we bring to GAF service in Glen Avon.
We can match the shingles, but the bigger issue is the tie-in. If the garage conversion was never permitted, the county may flag it during as-built discovery before we tear off. We handle that correction first, then re-roof both the garage and the tie-in so the transition is actually flashed and waterproof, not just matched in color, just as we do for GAF repair in Pedley.
We handle tile roof repair, including cracked or slipped tiles, re-bedding ridge caps, and underlayment patches, with Bloomington tile roof repair running $600 to $2,500. We also do full roof replacements on stucco ranch homes, including re-decking where original felt has dried out over spaced sheathing. Call (855) 600-3192 for a tile-by-tile assessment.
