Fast, Reliable Roof Replacement Across Mentone
Roof replacement in Mentone usually runs $9,500 to $22,000 for a standard architectural shingle tear-off on a ranch home, depending on square footage, decking condition, and how much wind damage the west and north slopes have absorbed. We get calls from Mentone homeowners on both sides of that range, and the difference almost always comes down to what the tear-off uncovers. Oakmont Roof Repair has been replacing roofs in the 92359 zip code long enough to know that a Mentone roof rarely fails the way the textbook says it should. Call (866) 942-0875 and we’ll walk the roof with you, measure it properly, and price the real job before you spend a dollar.
Why Oakmont Roof Repair Is Mentone’s Preferred Roof Replacement Company
Mentone is not Redlands and it’s not Yucaipa. The houses sit on larger lots, the rooflines are a patchwork of original mid-century shingle and flat-roof additions, and the wind comes down off Mill Creek Canyon with a real temper. We know that because we respond to the aftermath every winter. When a Santa Ana event tears through the 92359 area, the calls we get by the next morning are almost never about rain getting in. They’re about ridge caps in the yard, shingles hanging off the west slope, and a patio roof that suddenly looks wrong.
Noel Fierro built Oakmont Roof Repair around one straightforward idea: a roofing company should be able to explain exactly what your roof needs before you spend anything. That’s why our Mentone customers get an inspection first, a line-item scope, and a material recommendation pulled from seven brand lines rather than one. We answer our phone. We show up when we say we will. And we don’t disappear when the wind blows again.
Styles & brands we work with






Flat Roof Replacement in Mentone
Flat Roof Replacement in Mentone is one of the most common jobs we handle on older ranch homes, because the flat or low-slope patio additions and garage roofs that were tied into the original house decades ago were never designed for what Mentone throws at them. A flat roof on a Mentone addition ponds after a winter storm, bakes under the same high-desert sun that cooks the shingles, and the flashing where it meets the pitched roof is where wind-driven water finds its way in. In Mentone, a flat roof replacement typically runs $7,000 to $14,000 depending on the membrane, the insulation condition, and whether we’re pulling the old torch-down off the deck or recovering over it. The cheaper line on a flat roof is usually the trap, because the deck underneath is often worse than the surface suggests.
When Patching Stops Making Sense
If the membrane has cracked open in more than a couple of spots, or if you can see ponding that doesn’t dry within 48 hours, the roof has lost its slope and its surface at the same time. We’ll tell you whether a patch buys you a year or wastes your money. Most of the flat roofs we replace in Mentone were last done with a single layer of torch-down that was never intended to carry standing water, and the decking around the drain has gone soft.
Tie-Ins to the Main House
The real problem on a Mentone flat roof is rarely the flat section itself. It’s the tie-in. Where the flat patio roof butts into the back wall of the house or runs under a shingle overhang, the original flashing was short, nailed tight, and sealed with whatever was cheap in 1975. We pull that connection apart, inspect the wall sheathing behind it, and rebuild the flashing so water from the shingle slope sheds out over the membrane, not into the wall.
Roof Installation in Mentone
Roof Installation in Mentone is the full-replacement option when a home needs more than a repair: either the decking is too far gone, the existing roof is at the end of its service life, or you’re planning to stay in the house and don’t want to revisit the roof again in ten years. In Mentone, a complete roof installation on a typical 1,600 to 2,200 square foot ranch runs $11,000 to $20,000 for architectural shingles with full underlayment, new drip edge, and starter strip, and more if we’re also rebuilding flat sections or replacing tile. Our role is to give you the honest breakdown of what a new roof should include in this climate, not to sell you the most expensive shingle in the catalog.
What a Mentone Roof Actually Needs
Because Mentone roofs fail from wind uplift and UV far more than from rain, we spec every installation with a starter strip and a six-nail pattern on the west- and north-facing slopes, even when the rest of the roof gets the standard four-nail field. The wind rating lives in the nailing, not the shingle. We also check the existing roof-to-wall flashings and replace any that were originally installed too short, because those are where the wind finds its lever.
Decking Inspection Before Any Shingle Goes Down
Noel Fierro’s rule is simple: we don’t install over a deck we haven’t inspected. When we tear off in Mentone, we check the plywood or plank decking for soft spots along the eaves, around pipe penetrations, and under any area that showed water staining. If the decking is rotted or wind-fatigued, we show you what we found before we replace it, and the cost is written into the scope before the first new sheet goes down.
Trusted Brands We Service in Mentone
We carry seven major roofing manufacturer lines, including CertainTeed, Owens Corning, IKO, and Atlas, so the recommendation you get on a Mentone replacement is driven by what your roof needs, not by what we happen to have in the yard. For a home in the wind path off Mill Creek Canyon, that often means a heavier architectural shingle from Owens Corning or CertainTeed rather than a three-tab. For a tighter budget, IKO and Atlas give you a legitimate roof without pretending it’s something it isn’t. We stock starter strip, hip and ridge cap, and underlayment locally, so we’re not waiting on a supply run in the middle of your tear-off.

AfterCommon Roof Replacement Problems We See in Mentone Homes
- Santa Ana wind damage on west and north slopes: Ridge caps come off first, then the edge shingles lift, and then the field starts to peel. We routinely find that the last roofer nailed the edges with the same pattern as the field, which is a guaranteed failure in canyon wind country.
- UV-cooked shingles on mid-century ranch roofs: The original three-tab on a 1960s Mentone home has usually lost its granules and its seal strip years before any leak shows. The roof looks intact from the street until you walk it and see the bare mat showing through.
- Ponding flat-roof patio additions: The back-patio flat roof that was added onto so many Mentone ranch houses pools water after a winter storm, and the standing water cracks the membrane within a season or two. The transition flashing is where we find the rot.
- Mixed pitched-to-flat transitions that never worked: Mentone’s housing stock isn’t uniform tract. It’s a main pitched roof with a flat garage or patio section tied in. The flashing at those transitions was often built by whoever added the room, and it’s the first place water gets in.
Pricing for Roof Replacement in Mentone, CA
Expect to budget $9,500 to $22,000 for a full architectural shingle replacement on a Mentone home, with flat sections adding $7,000 to $14,000 when the patio or garage roof is part of the project. The spread comes down to square footage, decking repair, the number of slopes facing the canyon, and the material tier you choose. We’ve also seen decking on older Mentone homes that was never tongue-and-groove or plywood; when we replace it, that’s an additional line item we show you before the job expands. A written, line-item estimate from us is free, and it’s the only way to know whether the number you’re comparing against another bid is for the same roof. Call (866) 942-0875 to schedule a measurement.

FAQs About Roof Replacement in Mentone
Because the decking under an older Mentone roof is often worse than the shingles on top suggest, especially along the eaves where canyon wind has been working the drip edge for decades. We write a decking allowance into every Mentone quote and show you the rotted sections before we replace them, so the change is priced and approved in writing, not sprung on you at the end.
Usually yes. The nailing pattern matters more than the shingle itself, so we install a starter strip and a six-nail pattern on west- and north-facing slopes even on roofs that aren’t full replacements. For the shingle, a heavier architectural line from Owens Corning, CertainTeed, or IKO handles Mentone’s combination of downslope wind and elevation sun better than a three-tab.
We treat it as its own roof. That means checking the ponding pattern, pulling the old membrane to inspect the deck, rebuilding the tie-in flashing against the main house, and installing a membrane rated for standing water and UV. A flat section on a Mentone addition rarely gets replaced correctly as part of a shingle job unless the crew actually opens it up.
A roof is measured in squares of one hundred square feet, including all slopes, plus waste. We measure every plane and write the square count on the estimate. When you compare bids in Mentone, line up the square count, the decking allowance, the underlayment type, and whether the flat sections are included. If one bid is thousands lower, it’s usually because something got left off the scope. Call (866) 942-0875 and we’ll explain our numbers without making you chase us.
We install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. That means your recommendation is based on wind resistance, UV exposure, and budget, not on whichever brand we’re contracted to sell. We stock the common accessories locally so a Mentone job doesn’t stall waiting on materials.
