Kurt Hensley started Orange County Roofing Co with one rule that still drives the crew today: the right roof wins, not the one with the highest contractor margin. That matters in Valley Glen because the houses here have specific problems that a generic roofer from the coast won’t recognize until the old shingles are in the dumpster. We carry seven major brands, so when we tell you a GAF architectural shingle beats a three-tab for your west-facing slope, it’s because the material comparison says so, not because we only sell one product.

Why Orange County Roofing Co Is Valley Glen’s Preferred Roof Replacement Company

We’ve torn off and replaced roofs on Ethel Avenue, Burbank Boulevard, and the streets west of Valley College, and the same pattern shows up almost every time: original 1950s construction, shingles that look fine from the curb, and decking underneath that’s dried and split from sixty years of San Fernando Valley heat. That’s not a problem. That’s just Valley Glen, and we plan for it before the dumpster arrives. Our Roof Replacement crew is the same team that handles your inspection and any repair work, so the guy who tells you the decking is shot is the same guy who’s going to fix it. No hand-offs, no re-explaining your roof to a stranger.

We also carry more material options than any single-brand roofer in the area. GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, Boral. Seven manufacturers, each with different warranty tiers and price points. When a homeowner off Vanowen Street wants a cool-roof shingle to fight the afternoon heat, we can show them three brands that make one and compare cost per square honestly. That’s the whole point of being material-agnostic.

And yes, inspections stand alone. If you’re selling a Valley Glen house or just bought one and want to know what’s under the shingles, we’ll inspect it and give you a straight report. We won’t invent a replacement you don’t need. If the roof has five good years left, we’ll tell you that too.

Roof Installation in Valley Glen

Roof Installation in Valley Glen means full tear-off down to the decking, inspection and replacement of any damaged wood, and a new roofing system built for valley heat rather than coastal fog. In this part of the San Fernando Valley, most of what we install goes onto low-pitch gable and hip roofs on single-story ranch homes from the 1950s and 60s, plus some two-story infill. A full installation here runs $9,500 to $18,000 for standard architectural shingle systems; adding high-temp underlayment, upgraded ridge venting, or cool-roof-rated shingles shifts the number up from there. The job takes 3 to 6 working days once materials are on-site.

Post-WWII Ranch Roof Systems

The classic Valley Glen house is a post-WWII ranch with a 3:12 or 4:12 pitch, maybe a hip section over the carport, and a gable facing the street. Those roofs were built with 1×6 skip-sheathing and felt paper, sometimes two or three layers of shingles by now. We tear off down to the framing, replace what’s split, and build the new system to current code, including proper ventilation at the ridge and eave. That ventilation is not a nice-to-have here. An attic that hits 140°F in July cooks shingles from below and shortens the life of the whole roof.

West-Facing Slopes and Cool-Roof Choices

On a 1958 ranch off Ethel Avenue, our crew tore off three layers of brittle composition shingle and found original 1×6 skip-sheathing that had dried and split from decades of valley heat. We replaced the damaged decking, installed a high-temp ice and water shield in the valleys, and finished with GAF Timberline HDZ architectural shingles, nailed to the 130 mph wind spec, plus a ridge vent to help the attic breathe. For west-facing slopes like that one, we often recommend a lighter-colored or cool-roof-rated shingle from Atlas or CertainTeed. The afternoon sun in Valley Glen is brutal, and a reflective surface can drop attic temperatures enough that you’ll notice it in the AC bill.

Roof Replacement Contractor in Valley Glen

A Roof Replacement Contractor in Valley Glen has to be ready for what’s under the shingles, not just what’s on top of them. We are, because most of our work in the 91404 area is on homes where the original decking is still in place and has to be inspected plank by plank once the old roof comes off. Full replacement with decking repair as needed typically lands between $10,500 and $21,000. The quote includes a written allowance for decking replacement, so you’re not hit with a surprise change order when we find split boards. Any visible damage gets photographed, documented, and priced in writing before we touch it.

Skip-Sheathing and Decking Replacement

A lot of Valley Glen roofers quote around the possibility that the decking might be bad. We write it into the contract from the start, because we already know what’s under there. Original 1×6 boards with gaps between them, dried and cracked from heat, sometimes with old nail holes that won’t hold a new fastener. We replace what’s needed with modern plywood or OSB, nail it to code, and re-deck the whole roof if the framing demands it. That’s a line item with a fixed cost per sheet, not an open-ended hourly charge.

Flashing, Underlayment, and Valleys

Shingles get the attention, but flashing and underlayment are what keep water out of a Valley Glen house during the rare heavy rain that hits the Valley in winter. On mid-century homes, the old valley flashing was often nothing more than a thin strip of galvanized metal that’s now corroded. We replace valleys with high-temp peel-and-stick membrane, install new drip edge at the eaves, and re-flash every penetration, plumbing stack, and chimney with materials rated for the heat load we see out here. A roof that leaks ten years early is almost always a flashing failure, not a shingle failure.

Trusted Brands We Service in Valley Glen

We stock and install Atlas, Tamko, Boral, GAF, and three other major manufacturers, which means the material conversation in Valley Glen starts with your roof’s exposure and your budget, not with whatever brand we happen to have a truckload of. A west-facing slope on a 1955 ranch calls for a different shingle than a shady north pitch on a two-story infill. We’ll show you the differences in granule loss, wind rating, warranty tier, and cost per square, then let you pick. Manufacturer-backed warranties range from 20-year basic to lifetime limited, depending on the brand and system you choose. The right material for your roof, backed by the manufacturer’s own warranty. That’s the way it should work.

Common Roof Replacement Problems We See in Valley Glen Homes

• West-facing slope failure. The afternoon San Fernando Valley sun hits the west side of the roof hardest, baking granules off shingles and cracking the asphalt mat years before the rest of the roof. We regularly see west slopes that need replacement while the east-facing side still has life in it.
• Dried and split skip-sheathing. Original 1×6 boards from the 1950s and 60s have been cooking in the attic heat for six decades. Once we tear off the old shingles, we often find boards that snap under foot and can’t hold a nail. That requires decking replacement, which most one-brand roofers won’t quote up front.
• Outdated flashing at valleys and penetrations. The old galvanized metal and worn felt paper around chimneys, plumbing stacks, and valley intersections leaks during the heavy winter rains, even when the shingles look intact. It’s the most common hidden problem on a mid-century Valley Glen roof.
• Multiple layers of old shingles. Because the valley climate is dry and roofs don’t rot as fast as they do near the coast, a lot of original owners just nailed a second or third layer over the first. When that happens, we tear everything off and start clean. You can’t fix what you can’t see, and a third layer hides a lot of damage.
