Our Residential Roofing Services
RESIDENTIAL ROOF REPLACEMENT
When repairs no longer pencil out, we replace your roof from the deck up. That means a full tear-off, an inspection of the decking for hidden damage, and a rebuild with fresh underlayment, flashing, and ventilation, never new shingles laid over old problems. We pull the proper Washington County permits, walk you through material options with honest tradeoffs, and back every replacement with a written estimate and workmanship warranty.
RESIDENTIAL ROOF REPAIR
Most roof problems in St. George start small: a slipped tile, failed flashing around a chimney or vent, a hairline crack opened up by thermal cycling. Monsoon season turns them into interior damage fast. We track down the actual source of a leak instead of patching symptoms, document everything with photos, and move quickly on storm and wind damage. If a repair buys you several more years, we'll tell you honestly rather than push a replacement you don't need.
EMERGENCY LEAK REPAIR
When water is coming through your ceiling, you can't wait days for a callback. We respond fast to active roof leaks across St. George and Washington County, especially during monsoon season when a small failure floods an attic within hours. Our crew locates the true source, not just the wet spot, and makes a durable repair rather than a temporary patch. We handle storm and wind damage the same way, and we document everything with photos so you know exactly what failed and what we fixed.
TILE ROOFING
Concrete and clay tile are the signature roofs of Southern Utah, and for good reason. Their thermal mass helps hold down attic temperatures under relentless high-desert sun, and quality tile can last 40 to 50 years or more. The real lifespan driver is what goes underneath, so we install high-temperature underlayment rated for St. George's UV load rather than the bargain felt that fails early here. We handle everything from full tile systems to single broken-tile repairs on Washington County homes.
ASPHALT SHINGLES
Asphalt shingles remain the most cost-effective roof for St. George homeowners, and today's architectural shingles far outperform the old 3-tab style. We specify Class 4 impact-rated, algae-resistant products from established manufacturers. Paired with synthetic underlayment and proper ridge ventilation, that combination lets a shingle roof reach its full 25-to-30-year life in a high-UV desert climate instead of fading and curling early.
METAL ROOFING
Metal is our top pick for long-term value in this climate. Standing-seam and R-panel systems in Galvalume or aluminum reflect radiant heat instead of absorbing it, easing the load on your AC through triple-digit summers. With a 40-to-70-year lifespan and strong resistance to wind, hail, and UV, a properly installed metal roof often outlasts every other option, and its Class A fire rating adds another layer of protection.
Our Commercial Roofing Services
FLAT & LOW-SLOPE ROOFING (TPO, EPDM, PVC)
Most commercial buildings in St. George run flat or low-slope roofs, and they demand different systems than a pitched residential roof. We install and service single-ply membranes including TPO, EPDM, and PVC, chosen for the pooling water, thermal movement, and intense UV that work against every flat roof in this climate. Heat-welded seams create leakproof strength that resists punctures and chemical exposure, and we size each system to the building, from a small retail space to a full warehouse.
ROOF COATINGS & RESTORATION
A failing commercial roof doesn't always need a costly tear-off. Silicone, acrylic, and elastomeric coating systems restore aging roofs and can add years of service life by sealing cracks and creating a seamless, waterproof surface. In St. George's heat, reflective coatings do double duty: they lower rooftop temperatures and cut cooling costs across the summer. For many building owners it's the most cost-effective way to protect the roof and delay a major capital expense.
COMMERCIAL ROOF MAINTENANCE & INSPECTIONS
The cheapest commercial roof problem is the one caught early. We offer scheduled maintenance and inspection programs that extend roof life and hold down repair costs, using thorough condition reporting to find seam failures, drainage issues, and membrane damage before they reach the interior. Regular inspections also protect your warranty coverage and keep your building's roof performing through monsoon season and beyond.
Roofing Problems We Solve in St. George
Monsoon Leaks
July through September, thunderstorms drop a month of rain in an afternoon. If water is finding its way in around vents, valleys, or skylights, we find the entry point and seal it correctly, not just where the stain shows.
Cracked & Slipped Tiles
Thermal cycling between 100°+ afternoons and cool desert nights expands and contracts tile until it cracks or walks out of position. We replace broken tiles and check the underlayment beneath them, which is usually the real problem..
UV & Heat Aging
St. George gets some of the most intense sun exposure in Utah. Asphalt shingles here dry out, curl, and shed granules years earlier than they would up north. We'll tell you honestly how much life your roof has left.
Wind & Storm Damage
Microbursts and gusts funneling off Pine Valley Mountain and through the Virgin River corridor tear off shingles and ridge caps. We document everything with photos you can actually use.
Flashing & Penetration Failures
Most "mystery leaks" aren't the roof surface at all. They're flashing around chimneys, swamp coolers, and vent stacks. We inspect every penetration, because that's where desert roofs fail first..
Aging Flat Roofs
- Foam and membrane roofs on older St. George homes chalk, crack, and pond. Sometimes a coating buys you a decade; sometimes it's throwing money at a roof that's done. We'll tell you which — and why.
Why are we the Best Residential Roofer
in St. George, Utah?
Local knowledge that actually matters
A roofer who mostly works the Wasatch Front is solving snow-load problems. Down here the enemies are UV, thermal cycling, monsoon squalls, and wind-blown sand off the Red Cliffs Desert Reserve. We build and repair for this climate specifically.
Straight answers
You'll get a repair recommendation when a repair is the right call. Our estimates are itemized so you can see exactly what you're paying for — and compare us line by line against anyone else's bid.
Documentation you can use
Every inspection comes with photos. If your damage is storm-related, that documentation is exactly what an insurance conversation requires.
Respect for your home
Tarped landscaping, daily cleanup, magnetic nail sweep, and a final walkthrough with you before we call it done.
Our Roofing Process
01
Free Inspection
We walk the roof, photograph everything, and check the spots desert roofs fail first — underlayment, flashing, penetrations, and seams. Takes about an hour, and you get the photos either way.
02
Honest Estimate
A clear, line-item written quote, usually within 24–48 hours. If a $400 repair solves it, we won't pitch you a $14,000 replacement. If the roof is done, we'll show you why in the photos.
03
The Work
We pull the required City of St. George permit, protect your landscaping, and get it done — most repairs finish in a day, most full replacements in one to three, weather permitting. During tear-off we inspect the decking underneath and show you anything we find before touching it.
04
Final Walkthrough
Full cleanup, a magnetic nail sweep of your yard and driveway, and a walkthrough of the finished roof with you — including the photos of the completed work — before we call the job done.
How Much Does a New Roof Cost in St. George?
For most St. George homes, a full roof replacement runs roughly $7,000 to $18,000, depending on size, material, pitch, and how many layers come off. Repairs are far less, often $300 to $1,500 for tile swaps, flashing fixes, and leak repairs. Here's what typical projects look like in Washington County:
*Typical ranges only. Final pricing depends on roof size, pitch, material, and access.
*Ranges reflect typical Washington County projects and are estimates only. Your exact price depends on your roof's size, pitch, material, and condition — which is why the inspection and written estimate are free.
What drives the price in St. George specifically: roof size and pitch, material choice (tile costs more up front but outlasts shingle here), tear-off layers, decking condition underneath, and permit requirements. The City of St. George requires a building permit for roof replacement.
