Most repairs on Hemet’s 1960s – 1980s tract houses take one day once materials arrive, and we give you a written price before any work starts. If you’re dealing with a leak, missing shingles, or rotting fascia on a single-story home off Florida Avenue or in East Hemet, call (341) 208-3988 for a free estimate.

Why Brennan Roofing Co Riverside Is Hemet’s Preferred Roof Repair Company
Hemet homeowners don’t need another roofer who quotes low and then “discovers” problems at the door. Travis Oakley runs this crew under The Garrison Standard: the price goes on paper before any work begins, and it does not move. Every technician who shows up in Hemet is background-checked, uniformed, and dispatched from our Inland Empire office with the exact scope of work already written out. There’s no pressure pitch on your driveway.
We’ve earned our reputation in Hemet by doing what this valley’s housing stock actually requires. Homes here weren’t built for sixty years of intense UV, and the original materials don’t owe anyone anything anymore. When we open up a 1974 ranch in Valle Vista or a 1982 composition roof near Hemet High, we expect baked decking, failed flashing, and drip edge that’s rusted through. We price for reality, not for the best-case scenario, so you’re not hit with a new number halfway through the job.
Every repair is backed by our 365-Day Done Right Promise: in writing, for one full year, and we come back for free if it fails within that period. That’s the guarantee. That’s The Garrison Standard.
Styles & brands we work with






Commercial Roof Repair in Hemet
Commercial Roof Repair in Hemet usually means flat or low-slope membrane work on the retail and office buildings along Florida Avenue, Sanderson Avenue, and the industrial pockets near Devonshire Avenue. The heat here doesn’t just wear out shingles; it bakes modified bitumen and TPO seams until they split. When a Hemet storefront owner calls us, the problem is almost always water getting in through a failed seam, a cracked penetration boot, or a drain that’s been plugged with grit blown off the nearby foothills. Typical commercial patch and seam reseal work in Hemet runs $700 – $2,400 depending on roof size and access. Full recovery or coating projects on larger flat roofs run higher, often $4,500 – $14,000, and we write every number down before we start.
Flat Roof Patches and Penetration Work
Most Hemet commercial roofs are patched, not replaced. We reseal failed seams, replace cracked pipe boots, repair ponding areas, and reinforce drains. The sun’s UV is the primary enemy, followed by the sudden winter downpours that expose every weakness. We document the repair with photos so you can see exactly what was done.
Tenant Improvement Roof Tie-Ins
When a Hemet commercial building changes tenants, the roof often needs work around new HVAC curbs, exhaust vents, and conduit penetrations. We cut in clean tie-ins at curbs, flash them properly with new metal, and get the roof watertight before the drywall goes up inside. That’s the same written-price rule we apply on every job: you approve a number in writing before tools come off the truck.
Roof Leak Repair in Hemet
Roof Leak Repair in Hemet needs to account for the long dry spells that hide leaks until the first real rain hits. A small crack in the flashing might not show itself for months, because the water evaporates in the attic heat before it stains the ceiling. Then a December storm rolls through Hemet and suddenly the ceiling in the hallway is wet. We trace the leak to its source, not to its symptom. That matters on Hemet’s older homes, where water often travels along rafters before dripping far from the actual breach. Leak repair on a single-story Hemet ranch runs $350 – $750 for isolated flashing or vent boot replacement, $800 – $2,200 for valley, dormer, or chimney work, and more when decking has rotted underneath.
Valley and Flashing Repairs
On Hemet’s low-slope ranches, the valleys are the usual leak point. Original 1970s valley metal is often rusted through or lifted, and the old underlayment underneath has dried out and lost its seal. We cut out the old metal, install new ice and water shield, and lay in fresh valley flashing that moves water off the roof instead of holding it there.
Vent Boot and Pipe Collar Replacement
The rubber boots around plumbing vents crack from Hemet’s heat faster than anything else on the roof. They’re cheap to fix when caught early. We inspect every boot within reach when we’re on the roof for any repair, because a ten-minute boot replacement today beats a drywall patch and a mold call next spring. Call (341) 208-3988 and we’ll take a look.
Trusted Brands We Service in Hemet
We install and repair materials from CertainTeed, Owens Corning, and IKO, among other manufacturer lines. For Hemet’s older homes, that matters: the three-tab composition shingles on houses built in the 1970s and 1980s are still available in certain colors, and we stock or source local matches so a repair doesn’t look like a bandage. Where an older roof is beyond patchwork, we’ll explain your options in plain terms, including Class A fire-rated architectural shingles that meet what Hemet insurers and Title 24 are asking for. You choose the material with real numbers in front of you, not a sales pitch.

AfterCommon Roof Repair Problems We See in Hemet Homes
- UV-baked decking that crumbles on removal. On a 1978 ranch in East Hemet, the plywood under old three-tab is often so dry that it splinters when lifted. We check the decking before we commit to patching over it, because new shingles over rotted wood is a warranty claim waiting to happen.
- Dried-out shake underlayment from the original build. Many Hemet homes still have the original 1970s wood shake underlayment beneath a later shingle overlay. It’s brittle, it wicks water, and it fails at the soffit and fascia during winter rains. We strip it out and start clean.
- Missing or rusted drip edge on low-slope ranch roofs. Without drip edge, rainwater runs under the shingle edge and into the fascia board. Hemet’s ranch homes built without it now have rotted fascia and peeling paint along the eaves. We replace the drip edge as part of the repair.
- Granule loss on west-facing slopes in East Hemet. Afternoon sun reflecting off the San Jacinto Mountains accelerates UV exposure on west-facing roof planes. We see bare spots and brittleness there years before the rest of the roof. Our roof repair crews inspect those slopes more carefully than in neighboring valleys like San Jacinto or Menifee.

FAQs About Roof Repair in Hemet
Because the plywood decking has been baking under Hemet’s sun for forty to sixty years, and it loses its structural integrity from the top down. When we lift old shingles and the decking crumbles or flexes underfoot, code and basic safety require us to replace it before we install new roofing over it. On a 1972 Acacia Avenue ranch we opened last fall, the decking under a shake-to-three-tab overlay was so dried out it pulled apart by hand. We stripped to the rafters, replaced the decking, and brought the roof up to current fire and Title 24 standards. You can’t patch over rot. Call (341) 208-3988 and we’ll inspect what you actually have.
For a repair that covers less than 50% of the roof surface or fewer than a certain number of squares, you can usually patch without triggering full cool roof compliance. But once the repair crosses into what the state considers a re-roof on an older Hemet home, Title 24 requires a cool roof rated material, which means architectural shingles with reflective granules. We’ll tell you plainly whether your leak repair stays a repair or becomes a compliance job. Either way, the price is in writing before we start. Estimates are free at (341) 208-3988.
Because original wood shake roofs are unrated or low-rated for fire resistance, and Hemet sits in a burn zone where insurers won’t renew policies on homes with shake roofs. That’s why many Hemet homeowners get a letter requiring a full replacement with Class A rated materials before their policy renews. We strip the old shake, replace the decking where needed, install new ice and water shield in the valleys, and lay down architectural shingles with a Class A rating. The 365-Day Done Right Promise covers the work for a full year, in writing. Call (341) 208-3988 for a written quote.
The valley, where two roof planes meet and the original metal flashing has rusted through or separated. Hemet’s low-slope ranches concentrate a lot of water in a narrow channel during a heavy storm, and any weakness there becomes a leak immediately. We cut out the old valley, install new ice and water shield, and lay in fresh metal or membrane. On homes in East Hemet and Valle Vista, we also check the drip edge while we’re up there, because missing edge metal causes just as many leaks along the fascia. Call (341) 208-3988 for a free estimate.
We can match most three-tab composition colors from CertainTeed and other manufacturers that still produce the lines used on Hemet tract homes. The bigger issue is sun fading: a repair on a roof that’s been in Hemet’s sun for fifteen years will show some color difference, even with the exact same shingle. We’ll tell you that before we start, not after. If you want the repair to blend, we can discuss a full re-reroof or a larger contiguous section with new shingles. Either way, you’ll have the price in writing before anything goes on the roof. Call (341) 208-3988.
