Fast, Reliable Roofing Company Across Mendota
Roofing work in Mendota is not like roofing work in Fresno or the Bay Area. The heat, the dust, the swamp coolers, and the flat low-slope roofs on older stucco homes all change what fails first and what it costs to fix. We dispatch crews into Mendota weekly from our Central Valley office, and our technicians know Derrick Avenue, Bass Street, and the farm roads west of town the way a local should. If you need a straight answer on what is wrong with your roof, start with a Roof Inspection - Mendota, then call (361) 320-9467. We answer with a live person, every time.
Why Brennan Roofing Is Mendota’s Preferred Roofing Company Company
Mendota homeowners have dealt with enough no-show roofers. We built our reputation here on showing up when we say we will, putting the price on paper before any work starts, and standing behind the result in writing. Every technician who steps onto a Mendota roof is background-checked and in uniform. You know exactly who is on your property. Our Roofing Company team follows the Garrison Standard on every job in Mendota, from a small elastomeric patch on a flat roof near the high school to a full tear-off on an acreage property off Highway 180.
Reviews from Mendota customers consistently mention the same things: the crew showed up inside the window, the job site was clean when they left, and the final invoice matched the written estimate. That does not happen by accident. It is how we operate. Travis Oakley, who leads the team, insists on it. If something is not done right, the 365-Day Done Right Promise says we make it right at no charge, in writing, for a full year.
We also know what Mendota roofs actually deal with. Radiant heat off west-facing slopes. Swamp cooler drip. Dust haze that settles into every seam. The difference between a roofer who learns that from three summers of repairs and one who reads about it online is real. We are the first kind.
Roofing Contractor in Mendota
A roofing contractor in Mendota handles more than shingles. Most of what we do here involves flat and low-slope systems over mid-century stucco houses and ranch-style homes, plus the occasional steep-slope section on a newer addition. The typical Mendota roof sees 100°F-plus afternoons for weeks at a time and almost no rain. That changes what materials make sense and what repairs last. A full reroof on a typical Mendota bungalow with a built-up flat system generally runs $8,000 to $14,000. A smaller repair, like patching a ponded area around a swamp cooler penetration, usually falls between $400 and $1,200.
Travis Oakley reminds every estimator to look at the whole roof, not just the spot the homeowner flagged. A tear in the modified bitumen near one evaporative cooler often means the other cooler is doing the same thing on the opposite slope. We scope the full system so the written price covers what the roof actually needs.
Our Mendota roofing contractor team pulls permits on every job that requires one, whether that is through the city or Fresno County depending on where the property sits. We do not start work until the homeowner has the price in writing and understands exactly what is getting replaced.
Low-Slope and Flat Roof Repair
Most Mendota homes built before 1980 have low-slope or flat built-up roofs. These systems fail from ponding water and UV breakdown far more often than from rain. We repair them with elastomeric patches, new flashing around penetrations, and reflective coatings rated for continuous San Joaquin Valley sun exposure.
Full Roof Replacement for Older Homes
When a Mendota roof has been patched too many times, we recommend a full replacement with materials that make sense for the climate. Reflective single-ply membrane or modified bitumen with a white top coat are common choices. We explain the options in plain language and give the price before anything gets torn off.
Commercial Roofing in Mendota
Commercial roofing in Mendota serves a different building stock than the houses. We work on the flat roofs of small commercial buildings along Highway 33, ag warehouses and packing sheds west of town, and the modest office and retail structures built in the 1970s and 1980s. These roofs carry HVAC units, exhaust vents, and rooftop equipment that houses do not. They also have to hold up under the same brutal thermal cycling. A commercial flat roof repair in Mendota typically runs $1,500 to $6,000 depending on the size of the damaged area, while a full commercial reroof starts around $6 per square foot and goes up from there based on membrane type and insulation requirements.
We scope commercial work differently than residential. Equipment curbs, drain locations, ponding patterns, and interior water damage all change the price. Our Roofing Company estimators walk the roof, document what they find, and put the repair or replacement scope on paper. No change orders at the door.
Built-Up and Modified Bitumen Systems
Older Mendota commercial buildings often have built-up or modified bitumen roofs. We repair these with compatible materials, not whatever is on the truck. Matching the system matters for the repair to bond and last through another five or ten summers.
Reflective Coatings and UV Protection
White reflective coatings extend the life of a commercial flat roof in Mendota by reducing surface temperatures and slowing UV degradation. We apply coatings after repairing the underlying membrane, not as a cover-up for a failing roof. The roof gets fixed first. Then it gets protected.
Trusted Brands We Service in Mendota
We install and service roofing materials from GAF, CertainTeed, Owens Corning, and Atlas, among others. For Mendota’s flat and low-slope roofs, we also work with Boral and Tamko products where the spec calls for them. We stock common repair materials for the systems we see most often around Mendota, so when a homeowner calls with a leaking swamp cooler penetration or a blistered west-facing slope, we can usually schedule the repair without a long wait for parts. Call (361) 320-9467 and we can tell you what we stock and what needs to be ordered. The answer comes from a live person.
Common Roofing Company Problems We See in Mendota Homes
- Swamp cooler drip ponding: Evaporative coolers drip constantly through the summer. That water lands on the same section of modified bitumen for years and creates a ponded, degraded area that eventually leaks. We see this on nearly every older Mendota flat roof we inspect.
- West-facing slope blistering: The afternoon sun on the west side of a Mendota roof pushes surface temperatures well past 140°F. Built-up and modified bitumen roofs blister there first, and those blisters crack and split within a few seasons. We check west slopes first on every inspection.
- Dust accumulation in seams and drains: Valley dust settles into every seam, scupper, and drain on a flat roof. When the rare atmospheric river storm does come through, clogged drains back up and water sits for days. We clear drains and seal seams as part of most flat roof repairs.
- Improper previous patches: Many Mendota roofs have been patched repeatedly with incompatible materials, often by handymen hired cheap. Those patches fail at the edges and create new leak paths. We cut out bad patches and redo them properly with materials that match the original system.
Pricing for Roofing Company in Mendota, CA
A small roof repair on a Mendota flat or low-slope home runs $400 to $1,200. A larger repair that includes new flashing and a reflective coating across one roof section usually falls between $1,500 and $4,000. A full roof replacement on a typical Mendota stucco bungalow runs $8,000 to $14,000, while a commercial flat reroof starts around $6 per square foot. What changes the price here more than anything is whether the roof is low-slope or steep, how many swamp cooler and plumbing penetrations exist, and whether the decking underneath has been saturated by years of slow ponding. We write the price down before any work starts. Call (361) 320-9467 and ask for Travis Oakley or any of our estimators. The estimate is free and the number does not move at the door.

FAQs About Roofing Company in Mendota
Yes, in many cases. Properties outside Mendota city limits and on larger acreage lots often fall under Fresno County jurisdiction, which means county permits and county inspections. We determine jurisdiction before quoting so the permit line item on your written estimate is accurate. We pull the permits and schedule the inspections. If a re-inspection is needed after a tear-off, we handle that too. Call (361) 320-9467 with your parcel address and we can tell you which authority applies.
They drip constantly through the summer, and that drip lands on the same section of modified bitumen every day for years. The standing water breaks down the membrane, softens the decking underneath, and creates an active leak that has nothing to do with rain. We repair these by cutting out the damaged section, installing new underlayment, flashing the cooler penetration with elastomeric material, and coating the area with a reflective finish. Then we check the cooler drain line so it does not re-create the same problem. Call (361) 320-9467 if you have a swamp cooler on a flat roof. This is one of the most common repairs we do in Mendota.
Yes. We handle detached garages, ag shops, barns with finished interiors, and converted ADUs on the rural lots around Mendota. These structures often have low-slope roofs or metal roofing, and they need their own permit handling, especially when well and septic setbacks are involved. We include outbuilding work in the same written estimate as the main house. If you have a shop off a dirt road with equipment access issues, tell us when you call. We plan the haul route and access before we quote so the price reflects reality. Call (361) 320-9467 to set up a time to have the property looked at.
We price each section separately, because a low-slope modified bitumen system and a steep-slope shingle section need different materials and different labor. Many Mendota homes have an original flat roof with a newer pitched addition, and quoting one material for the whole house would be wrong. Our written estimate shows the low-slope scope on one line and the steep-slope scope on another, so you see exactly what each part costs. Call (361) 320-9467 and we will walk the roof with you and explain what each section needs.
Because they take the full force of the afternoon sun, which pushes surface temperatures past 140°F in the summer and causes thermal expansion and UV breakdown that the cooler north and east slopes do not experience. Blistering, cracking, and granule loss show up on the west slope years before the rest of the roof. We pay close attention to west-facing sections during every Mendota inspection and recommend coating or membrane upgrades there before small blisters become open splits. If your west slope looks rough, call (361) 320-9467. We will tell you honestly whether it needs repair now or can wait another season.
