Why Highland Residents Choose Us for GAF Service
We only do roofing. That’s not a slogan; it’s the reason our crews can tell you the difference between Timberline HDZ and UHDZ sealant behavior after three Highland summers, or why your ridge caps lifted on the north hip but not the south. Roland Cifuentes, our owner, learned roofing through Chaffey College’s construction technology program and spent years working Inland Empire roofs before starting Ridgeway Roof Repair. He’s the guy Highland neighbors call after a Santa Ana wind tears something loose. We know GAF sales & service from tear-off to final inspection, and we bring that to every job across Highland service area.
When you call us about a GAF roof, you get a straight read on what actually needs fixing versus what can wait. That’s how we’ve built our name here.

Common GAF Roofing Problems We Solve in Highland
- Granule loss and mat oxidation on Timberline HDZ. Highland summers routinely top 100°F, and that sustained UV cycles shingle mats hard. We regularly see HDZ fields wearing through years earlier than the nominal lifespan, especially on south-facing slopes across mid-century tracts.
- Wind-lifted tab seals and creased shingles. Santa Ana gusts off the Cajon Pass hit exposed hip and ridge runs first. The lower-pitch ranch roofs common in older Highland neighborhoods take the worst of it, and lifted or creased shingle tabs are a recurring call for us, not a rare one.
- Blown-off ridge caps. When a Santa Ana event comes through, we get calls about ridge caps scattered in yards across Highland. It’s usually a fastener and sealant issue made worse by heat-brittled cap material, and it’s a sign the rest of the ridge line needs attention.
- Baked-out underlayment beneath serviceable shingles. On 1980s and 1990s tract homes already on their second or third roof, the felt and decking often degrade faster than the GAF shingles above them. The shingle looks fine. The deck underneath is not.
- Vent screen and flashing failures in foothill ember zones. Homes climbing toward the national forest boundary in East Highland deal with wind-driven ember intrusion at vent screens, ridge vents, and flashing details. These are the same details that get skipped on a flat-basin job, and they matter more than the shingle warranty up here.
GAF Service in Highland: What Local Conditions Mean for Your Roof
Highland sits at the base of the GAF in San Bernardino area where intense inland heat, Santa Ana wind events, and the East Highland foothill interface combine to make roofing a fire-hardening and wind-uplift problem as much as a weatherproofing one. In the foothill neighborhoods east of Webster Street, roofers routinely deal with dry-rotted fascia and blown-off ridge caps after a gust, and wildfire-zone rules mean vent screens and ember-resistant details matter as much as the shingles themselves. That’s a different job than the flat-basin replacement mindset you’d get ten minutes down the 210. When we re-detail a ridge in those neighborhoods, we’re specifying Class A fire ratings, ember-resistant vents, and wind-rated fastening, not just slapping shingles over old felt. A GAF system only performs as well as the details around it, and in East Highland those details are the job.
GAF Models & Products We Service in Highland
We work across GAF in Redlands and Highland shingle lines and accessory details every week: Timberline HDZ architectural shingles, Timberline UHDZ premium architectural, Royal Sovereign 3-tab for older ranch-style homes, and GAF Liberty and other low-slope membranes for flatter sections. When keeping a GAF roof system intact makes sense, we use GAF-manufactured shingles, ridge caps, and accessory components so the warranty chain stays clean. We also say plainly when a quality aftermarket underlayment or flashing detail is the better value for a Highland roof. If the deck and felt are baked out, no shingle brand fixes that. We stock what Highland roofs actually need for fast turnaround, not whatever a single manufacturer pushes.

AfterGAF Service Pricing in Highland
| Service | Typical Range in Highland |
|---|---|
| Minor GAF leak repair | $350 – $750 |

What moves the number is the deck and underlayment, not just the shingle. On 1980s and 1990s Highland tract homes, the field shingle often looks serviceable while the felt underneath is baked out, and that’s the difference between a repair and a replacement. The estimate we give you is a written line-item quote, not a ballpark. Call (877) 588-7942 to schedule a free estimate and we’ll put numbers to what your roof actually needs.

FAQs – GAF Roofing in Highland
If you’re east of Webster in the foothill interface, yes, and it’s partly code-driven plus partly common sense. Class A fire rating and ember-resistant vent screens are the standard spec for wildfire-zone hardening in East Highland, and they matter as much as the shingle warranty when a Santa Ana pushes embers uphill. We can tell you what your specific roof currently has. Call (877) 588-7942 and we’ll check it during an inspection.
Some granule loss is normal, but heavy loss after 100°F summers means the mat is oxidizing faster than it should. South-facing slopes in Highland take the worst UV cycling, and we regularly see HDZ fields wearing through years before the warranty math would suggest. If your gutters are collecting granules, get the roof inspected before a leak starts. Call us for a structured inspection, not a sales pitch.
Usually it’s heat-brittled cap material combined with fastener and sealant failure at the ridge line. Once one cap lifts, the wind gets under the rest and peels the run. In Highland’s lower-pitch ranch roofs, exposed hip and ridge runs take the worst of it. We re-fasten and re-detail the ridge with GAF ridge cap specified for wind exposure, which is a different install than what most original builds had. Call (877) 588-7942 for a ridge inspection and exact quote.
Honestly, it depends on the roof, the exposure, and what you’re trying to harden against. We install GAF, handle GAF repair in Muscoy, and work with Owens Corning and CertainTeed, so we have no reason to oversell any of them. GAF’s Timberline HDZ is a strong architectural shingle, but the underlayment, flashing details, and venting matter more in Highland’s heat and wind than the shingle brand. We’ll quote your roof honestly. Estimates are free.
Usually, if the deck and underlayment are sound. We repair GAF roofs all the time, from lifted tabs to flashing detail leaks. But if the underlayment is baked out and the deck is soft along the fascia line, a repair is throwing money at a failing roof. We’ll show you what we find and give you a straight recommendation. Call (877) 588-7942 to schedule a leak inspection.
