Trusted Roofing Company for Riverside Homeowners
When your roof starts leaking in Riverside, the question isn’t whether to fix it. It’s who to let onto your property to do the work. Brennan Roofing Co Riverside answers that question with The Garrison Standard: a written price before any work starts, background-checked uniformed technicians who show up inside the promised window, and a full-year written guarantee on every job. Travis Oakley leads the crew here in Riverside, and he runs the same disciplined operation on every house, from single-story ranch homes near the Plaza to larger properties in Canyon Crest and Mission Grove. We answer the phone with a live person, every time. Call (341) 208-3988 and you’ll get a straight answer, not a voicemail.
Roofing Contractor
Roofing Contractor is the trade classification for the crew you hire to install, replace, or repair the roof system over your head, and in Riverside that means working with sun-baked asphalt shingles, clay tile, and the occasional metal panel. You need a licensed roofing contractor when the work involves anything beyond a quick visual check: torn flashing, lifted shingles, or a full tear-off and re-roof. Brennan Roofing Co Riverside handles all of it. A simple shingle repair in Riverside typically runs $350 to $750, while a full re-roof on a standard ranch home starts around $9,000 and climbs based on material and pitch.
Written Price Before Work Begins
The price goes on paper before a single shingle comes off. No change orders at the door, no “we found more damage” surprises. That’s the Garrison Code in practice.
Background-Checked Crews
Every technician who steps onto your Riverside roof has passed a background check and shows up in uniform. You’ll know exactly who is on your property and what they’re there to do.
Styles & brands we work with
Commercial Roofing
Commercial Roofing covers flat and low-slope roof systems on warehouses, retail buildings, office parks, and apartment complexes, and Riverside’s industrial corridors along the 215 and 91 freeways keep us busy with TPO, modified bitumen, and built-up roofs. You need a commercial roofing contractor when ponding water, membrane splits, or failing flashings start threatening inventory and operations. Brennan Roofing Co Riverside provides inspection, repair, and full replacement for commercial properties. Small commercial repairs in Riverside start around $800, while a 10,000-square-foot TPO replacement typically lands between $45,000 and $75,000 depending on insulation and deck condition.
Flat and Low-Slope Systems
Riverside’s summer heat does a number on single-ply membranes. We inspect seams, flashings, and drains, then give you a line-item report with the written price attached.
Minimal Disruption to Operations
We stage work around your hours wherever possible. The crew shows up clean, works tight, and leaves the lot free of debris and fasteners at the end of every shift.
Metal Roof Installation
Metal Roof Installation means putting a standing-seam or exposed-fastener metal roof on your home or building, and in Riverside’s inland heat, a metal roof reflects solar gain and outlasts asphalt by decades. Homeowners choose metal when they want a 40-to-70-year roof that won’t curl, crack, or blow off in the Santa Ana winds that tear through the pass. Brennan Roofing Co Riverside installs metal roofs from manufacturers including IKO and Atlas. A standing-seam metal roof on a 1,800-square-foot Riverside home typically runs $24,000 to $42,000, with exposed-fastener panels coming in lower.
Standing Seam Explained
The panels lock together with concealed fasteners, which means fewer penetrations and fewer leak paths over the life of the roof. It’s the higher-cost option for a reason.
Reroof Over Existing Decking
In many Riverside homes, we can install metal directly over the existing roof if the decking is sound, which skips the tear-off cost and keeps the old roof out of the landfill.
Residential Roofing
Residential Roofing is the installation, replacement, and repair of the roof on the home you live in, and in Riverside that means dealing with tile roofs in older neighborhoods, composition shingles in newer tracts, and the occasional flat roof over a mid-century addition. You need a residential roofer when shingles start shedding granules into your gutters, when tile cracks after a windstorm, or when a leak stains the ceiling after a hard winter rain. Brennan Roofing Co Riverside replaces and repairs residential roofs throughout Riverside County. A full composition shingle re-roof on a typical Riverside home runs $9,000 to $16,000; tile re-roofs start higher due to material and structural weight.
Shingle and Tile Expertise
We work with Owens Corning and CertainTeed shingle lines and match existing tile profiles on older Riverside homes so the repair doesn’t stick out like a patch.
Full Tear-Off or Layover
We’ll tell you plainly whether a layover makes sense or whether the decking needs a full tear-off. The written price covers whichever route the roof actually needs.
Roof Maintenance
Roof Maintenance is the scheduled inspection and minor repair work that keeps a roof watertight year over year, and in Riverside it’s a smart play given the thermal cycling that bakes sealants every summer and the winter rains that test every flashing seam. You need maintenance when you haven’t had a roofer look at the roof in two or more years, or when you see debris piling up in valleys and behind chimneys. Brennan Roofing Co Riverside offers a maintenance visit that includes a full visual inspection, minor sealant touch-ups, and a written condition report. For a complete guide to keeping your roof in top shape, see our Roofing Company Maintenance Checklist for Riverside Homeowners. A standard maintenance visit in Riverside runs $250 to $450 depending on roof size and access.
Seasonal Checkups
We recommend a spring checkup after the rains and a fall checkup before the next wet season. Catching a lifted shingle in October costs a lot less than replacing drywall in March.
Written Condition Report
Every maintenance visit ends with a written report that tells you what’s good, what’s wearing, and what the repair cost would be if you decide to act now. No pressure, just facts on paper.
Roof Coating
Roof Coating is a fluid-applied membrane that seals and extends the life of an existing flat or low-slope roof, and in Riverside it’s a common alternative to a full reroof on commercial buildings and older flat-roof homes. You need roof coating when a roof is structurally sound but the membrane is aging, showing hairline cracks, or losing reflectivity that was helping with cooling costs. Brennan Roofing Co Riverside applies silicone and acrylic coating systems to flat and low-slope roofs throughout Riverside. Coating a 2,000-square-foot flat roof in Riverside typically runs $4,000 to $8,000, depending on surface prep and the number of coats.
Silicone vs. Acrylic
Silicone handles standing water better and costs more; acrylic is the budget-friendly option that still reflects heat well. We’ll tell you which one fits your roof and your budget.
When Coating Beats Replacement
If the decking and insulation are dry, coating can add 10 to 15 years to a flat roof at a fraction of replacement cost. The written price covers all prep, priming, and finish coats.
Free Roof Estimate
A Free Roof Estimate from Brennan Roofing Co Riverside is a written, line-item price for your roofing project, delivered before any work starts and with zero obligation to hire us. You need a free estimate any time you’re considering a repair or replacement and want to know the real number without guessing. Our estimator will walk the roof, inspect the decking and flashings, measure the surface, and hand you a written price. Estimates are free whether you choose us or not, and the number on that paper is the number you pay: no door-knock adjustment, no change order games.
What the Estimate Includes
Material line items, labor, tear-off and disposal if needed, underlayment, flashings, and the warranty terms. Everything in plain English with the trade words explained.
No Pressure, Ever
We don’t run countdown clocks or “sign today” discounts. You take the written price, think it over, and call when you’re ready. The price holds because it’s honest.
Brands We Service
We install and repair roofing materials from IKO, Atlas, Tamko, and Boral, among other leading manufacturers. IKO shingles are a frequent choice on Riverside homes for their wind ratings and color range, and our crews are trained on their installation specs. Atlas shingles with their Scotchgard protection hold up well against the algae and moss that Riverside’s damp winter mornings can produce. Tamko’s laminated lines give homeowners a dimensional look at a strong price point, and we’ve installed them on projects from Corona to Perris.
Boral tile and stone-coated steel systems show up regularly on higher-end Riverside homes and in fire-prone foothill neighborhoods where Class A fire ratings matter. We follow each manufacturer’s installation requirements to the letter, because the warranty you get from the factory depends on the roof being done the way they specify. Whether your roof carries IKO, Atlas, Tamko, Boral, or any other make, we can repair it or replace it and stand behind the work in writing.

AfterSigns You Need a Pro Right Now
- Water stains on the ceiling or walls. This means water is already through the roof system. The longer it sits, the more decking and drywall you’re replacing. Call us the day you see the stain.
- Granules in the gutters or at downspout outlets. Asphalt shingles shed granules as they age, and heavy granule loss means the shingles are near the end. A quick inspection tells you how much life is left.
- Missing, cracked, or lifted shingles. Open gaps in the shingle field let water hit the underlayment directly. Riverside’s Santa Ana winds are rough on shingle edges, and what starts as one lifted shingle becomes a patch repair if left alone.
- Daylight visible through the attic or roof boards. If you can see light from inside the attic, water can see a way in. This is a flashing or decking failure, not something to put off until spring.
- Sagging areas or soft spots you can feel underfoot. A roof deck that gives when stepped on has moisture damage. The repair is bigger than shingles, and the sooner we open it up, the less structural work you’re facing.
Our Process, Step by Step
- 1
You call and a live person answers. No voicemail, no callback queue. We listen to what you’re seeing, ask the right questions, and schedule a visit inside a window we actually keep.
- 2
We inspect the roof top to bottom. Our estimator walks the roof surface, checks flashings, valleys, decking, and attic ventilation. Moisture meters and core samples tell us what’s actually going on under the surface.
- 3
You get a written price. The quote is line-item specific: materials, labor, disposal, underlayment, flashings. The number on that paper does not move at the door. No negotiation games, no pressure tactics.
- 4
We do the work with a uniformed, background-checked crew. The same people who showed up for the estimate are the people on your roof, in company uniforms, working to the manufacturer’s installation spec. Worksite is cleaned and magnet-swept for nails at the end of each day.
- 5
You get the 365-Day Done Right Promise in writing. If anything we repaired or installed fails within one full year, we come back and make it right at no charge. That guarantee is written, not implied.
How Much Does Roofing Company Cost in Riverside?
A typical roof repair in Riverside runs $350 to $750 for shingle work, $500 to $1,200 for flashing or valley repairs, and $250 to $450 for a maintenance visit with minor sealant touch-ups. A full composition shingle replacement on a standard Riverside home runs $9,000 to $16,000, while a standing-seam metal roof on the same home lands between $24,000 and $42,000. Flat roof coating typically runs $4,000 to $8,000 for a 2,000-square-foot surface.
What moves the price: roof pitch and access, number of layers being torn off, decking condition, and the material you choose. A steep tile roof with rotted decking costs more than a simple one-story shingle job with clean decking. The best way to avoid overpaying is to get a written, line-item price and compare it apples to apples. Our free estimate includes material line items, labor, disposal, and warranty terms in plain English. Call (341) 208-3988 to schedule yours.
