GAF Construction in Highland, CA | Hampton Contractors
We provide independent GAF roof installation and repair across Highland, CA. The thing that sets our GAF work apart here is simple: we’ve been rebuilding foothill-adjacent homes under GAF’s published installation specs since long before wildfire hardening became the county’s default requirement. If you need a GAF Timberline roof that passes a fire-severity inspection on the first try, call Hampton Contractors at (833) 467-4075 for a free estimate.
Why Highland Residents Choose Us for GAF Service
GAF shingles are only as good as the underlayment, flashing, and ventilation beneath them. We read GAF’s technical bulletins directly and install Timberline HDZ, Deck-Armor, and Ridge Vent to the manufacturer’s written spec. No shortcuts, no “good enough” substitutions. Homeowners who hire a General Contractor in Highland see the difference when the first Santa Ana wind event rolls through and nothing lifts.
Brent Calloway runs our crews the way he learned it in the High Desert, starting with a construction technology foundation at Victor Valley College and two-plus decades of framing, roofing, and remodeling since. He’s torn off enough failed roofs in Highland to know exactly where the weak points hide, and he’ll tell you straight up whether a repair will hold or a reroof is the only honest answer. We carry genuine GAF accessories, LayerLock nails, Ridge Vent, and Deck-Armor — the same materials we use for GAF in Redlands — because mixing off-brand components voids the wind and fire ratings the assembly depends on. No exceptions.
We’re an independent GAF service provider, not manufacturer-affiliated or authorized. That means we answer to you, not to a corporate warranty department. We also cover the whole home beyond the roof. From the roofline to the back patio, one contractor can handle the GAF roof, the James Hardie siding, the Belgard paver driveway, and the kitchen remodel under one project plan — whether you need GAF service in Loma Linda or right here in Highland.

Common GAF Construction Problems We Solve in Highland
- Curled and baked Timberline shingle tabs on south- and west-facing slopes. Highland’s inland heat and intense sun dry out shingle adhesive faster than most homeowners expect. Nail heads open up, wind gets under the tabs, and suddenly a roof that’s only twelve years old starts shedding granules and lifting at the edges. We replace the damaged field with matched Timberline shingles and check the underlayment before any repair.
- Failed underlayment exposed during wood-shake tear-offs. The original wood-shake roofs on Highland’s mid-century tract homes almost always sit over skipped or rotted underlayment. When we tear off wood shake and find failed GAF underlayment at valleys and eaves, that’s the exact spot where winter rain on foothill slopes finds its way inside. We rebuild with Deck-Armor before any shingle goes down.
- Superheated unvented attics cooking shingles from below. We routinely find attics in Highland that were built without proper ventilation. Pair that with Ridge Vent that isn’t actually pulling air because the intake is blocked, and the shingle deck gets hot enough to accelerate granule loss and premature cracking. Ventilation is a roof system problem, not a shingle problem, and we fix it as part of the assembly.
- Skipped drip edge and re-used flashing at walls and chimneys. This is the deficiency that fails fire-severity inspections even when the shingle itself looks fine. Ember-laden air and wind-driven rain need a gap to get through, and old flashing gives them one. We install new drip edge at every eave and rake, and re-flash penetrations to match the GAF assembly.
- GAF Liberty SBS low-slope membrane failures on porch and patio tie-ins. Highland homes with flat porch roofs or patio covers need a self-adhered membrane that can handle standing water and heat. When the original membrane splits or peels, we tear off the failed section and install GAF Liberty SBS with proper lap sealing.
GAF Service in Highland: What Local Conditions Mean for Your Equipment
Here’s the checkable fact that changes everything about GAF work in Highland. Much of the older tract stock in the foothill-adjacent neighborhoods still carries original wood-shake roofs, and San Bernardino County’s fire-severity review means a reroof or addition permit will not clear until that combustible roof is replaced with a Class A assembly. This is not a preference. It’s a permit requirement. A homeowner off Church Street or Base Line who wants to add a room, convert a garage, or even just reroof after a leak will find their project held at plan review because the existing wood shake fails the ember-resistance standard. So a GAF shingle spec in Highland is often the difference between a permit that clears and a project that stalls. Our crews have rebuilt enough of these assemblies to know the sequence cold: tear off the wood shake, remove the failed underlayment, nail down Deck-Armor, install new drip edge, and finish with a Timberline HDZ field rated Class A for fire resistance. That’s the roof that passes. On a mid-century home off the foothill streets of Highland, our crew tore off original wood shake that the county fire review had flagged and found failed underlayment at the valleys. We rebuilt the assembly with GAF Deck-Armor and Timberline HDZ shingles, added Ridge Vent and a new drip edge at the eaves, and left the homeowner with a Class A roof that finally passed the fire-severity inspection tied to their permit. Good work doesn’t need a disclaimer.
GAF Models & Products We Service in Highland
We install and repair the full GAF residential line you’re most likely to see in Highland. That includes Timberline HDZ and Timberline UHDZ architectural shingles, Timberline Ultra-Premium with LayerLock and the StrikeZone nailing zone, Deck-Armor waterproofing underlayment, and Ridge Vent ridge ventilation. For low-slope porch and patio tie-ins, we install GAF Liberty SBS self-adhered membrane. We stock common Timberline colors and Deck-Armor rolls locally for fast turnaround on Highland repairs. When a match isn’t on the truck, we order it same-week.

AfterGAF Service Pricing in Highland
Here’s the straight answer on what GAF work costs in the 92346 ZIP code.
| Service | Price Range |
|---|---|
| Roof Replacement (GAF Timberline HDZ) | $8,000 – $20,000 |
| Roof Repair (shingle replacement, flashing, underlayment) | $400 – $1,800 |
| Tile Roof Repair | $600 – $2,500 |
| Metal Roof Installation | $15,000 – $40,000 |
What moves the number? Roof pitch, tear-off depth (one layer versus three), whether the decking is rotted, and whether you need a full Class A assembly for a permit. A wood-shake tear-off with failed underlayment costs more than a straightforward reroof over a single layer. Every estimate includes a written line-item scope with exact materials, tear-off, decking repair, and disposal, so you know what you’re paying for before any nail goes down.

FAQs – GAF Construction in Highland
Yes. GAF Timberline HDZ shingles carry a Class A fire rating when installed as part of a complete Class A assembly with the correct underlayment. Highland’s fire-severity review under San Bernardino County requires a Class A roof before a reroof or addition permit clears, and a Timberline HDZ field over Deck-Armor underlayment meets that standard. We install to GAF’s published spec so the assembly passes the first time. Call (833) 467-4075 to schedule a roof evaluation for your Highland property.
It depends on how far the curling has gone and whether the underlayment is still intact. If the shingle tabs are lifting but the underlayment is sound, we can replace the damaged field and add proper intake ventilation to lower the attic temperature going forward. If the underlayment has been baked and cracking, a patch won’t survive the next Santa Ana season, and we’ll tell you that in writing. The estimate is free either way. Call (833) 467-4075 for an honest assessment.
Yes, when the roof is installed to spec. GAF Timberline HDZ carries a wind rating up to 130 mph with the proper number of nails and the StrikeZone nailing zone followed exactly. Most wind failures we see in Highland come from skipped nails, fewer nails per shingle than the spec requires, or missing starter strips. We install to the manufacturer’s written spec because that’s the only way the rating applies to your roof.
A GAF Timberline HDZ replacement in Highland typically runs between $8,000 and $20,000 depending on roof size, pitch, number of tear-off layers, decking condition, and whether you need the full Class A assembly for a fire-severity permit. A small single-story home with one shingle layer and good decking sits near the low end. A larger two-story with wood-shake tear-off, failed underlayment, and decking repair sits higher. Call (833) 467-4075 for a written, line-item quote on your specific property.
We can match most current-production Timberline colors, and for older discontinued colors we’ll find the closest match or recommend a clean field replacement. A repaired section of weathered shingles will always show some difference because the older shingles have granule loss and sun fading. We’ll be upfront about what the repair will look like before we start. Call (833) 467-4075 for a match check on your Highland roof.
