- ✓City of Grand Junction contractor's license through the Mesa County Building Department

- ✓We meet adjusters on the roof rather than emailing photographs and hoping
- ✓Free written estimates across Mesa, Delta, Montrose, Garfield and Rio Blanco counties
Grand Junction Premium Roofing handles roof replacement, leak repair, flashing and low-slope work across Grand Junction and the wider Grand Valley. We install architectural asphalt laminate, standing seam steel, single-ply TPO and PVC membrane, and we repair concrete and clay tile. Residential and commercial, with written scopes and free estimates across Mesa, Delta, Montrose, Garfield and Rio Blanco counties.
Longevity here is decided by the metal rather than by the shingle. Two-piece counterflashing set into a sawn mortar reglet, valley metal with correct laps, kick-outs where a roof meets a wall, and a six-nail fastening pattern sized for the wind that comes down the canyon. None of it is visible from the driveway and all of it decides the outcome.
We inspect before we sell. If your leak traces to a joint rather than to worn material, we will price the joint and say so in writing. If the roof genuinely has years left, that goes in writing too. Call for a written estimate, a second opinion, or a straight answer about what a roof actually needs. That conversation costs you nothing either way.
Why Grand Junction Chooses Grand Junction Premium Roofing
- ✓We read the inside of a house before pricing the outside, because on Mancos Shale a leak that returns each spring is movement rather than material wear.
- ✓Two-piece counterflashing cut into a sawn mortar reglet is our standard chimney detail, never an upcharge, because sealed one-piece metal fails here on a seasonal cycle.
- ✓We argue against impact-rated shingles on this side of the divide. Mesa County logged 14 hail reports from 2016 to 2025; Larimer County logged 143.
- ✓Inspection fees are never credited against work. An inspector who only gets paid when you buy a roof has stopped being an inspector.
- ✓Every replacement gets new flashing metal. Reused step flashing under fresh shingles is the most common reason a two-year-old reroof leaks in this valley.
- ✓If the right answer is a targeted repair, or spending nothing at all this year, our written report says that whether or not it wins the job.
About Grand Junction Premium Roofing in Grand Junction, CO
Grand Junction Premium Roofing works the Western Slope, and we build for the ground and the sky we actually have rather than for the Front Range. The Grand Valley floor is Mancos Shale, an expansive marine shale that swells when it gets wet and shrinks when it dries, and it dries often: annual precipitation normals out at 9.42 inches at the airport.
That single fact reorganizes the trade here. Buildings move, roofs are rigid, and the failure shows up at chimneys, valleys, curbs and parapets rather than out in the middle of a shingle field. So we lead with metal, we detail joints so they can slide rather than sealing them shut, and we read the inside of a house before we price the outside of it.
Here is when not to hire us. If a contractor has already diagnosed movement and an engineer is scheduled, do that work first and call us afterwards. If your roof is under ten years old, has intact granule cover, and your only complaint is its appearance, we will not sell you a replacement. And if you want somebody to file a hail claim on a roof that has no hail on it, we are the wrong company.
Our Roofing Services in Grand Junction, CO
Roof Replacement
Plenty of Grand Valley roofs come off years before they need to. We walk the inside of a house before we price a tear-off, because a leak that returns every spring at the same joint is usually a building moving, not a roof wearing out.
Roof Leak Repair
Very little leaks through the middle of a roof here. With 31 days a year reaching even a tenth of an inch of precipitation, and barely two passing half an inch, water rarely gets the dwell time to work through a shingle field.
Storm Damage Restoration
Storms here are rare and concentrated. Airport normals show roughly two and a half days a year reaching half an inch of precipitation, and about one day every five years reaching a full inch.
Hail Damage Roofing
On this page we argue against our own upsell. Colorado has a national reputation for hail, that reputation was earned on the far side of the Continental Divide, and the Mesa County numbers are nowhere near it.
Wind Damage Roofing
Wind is the load that genuinely takes roofs apart around here. The Grand Valley sits between the Book Cliffs and the Uncompahgre Plateau with the Colorado River cutting in through De Beque Canyon, and air moving through a gap that shape accelerates.
Roof Inspections
Our inspections start indoors, which surprises people who expected a ladder. On this ground the interior tells you things the roof surface cannot, and reading it first stops us writing a tidy roof report that misses what is actually wrong with the building underneath.
Asphalt Shingle Roofs
Asphalt covers most of the housing stock in this valley and it should. What it never quite gets here is a fair run at its rated life, because the thing aging it has almost nothing to do with water.
Metal Roofing
Metal earns its keep here for reasons unrelated to snow. This valley runs 135 days a year with a low at or below freezing and 57 with a high at or above 90, so a roof here swings through an enormous range and is in constant motion.
Tile Roofing
There is tile up on the Redlands, across parts of Orchard Mesa and through a scatter of newer subdivisions, and where it exists we maintain it properly. What we will not do is talk somebody with a perfectly good asphalt roof into converting over to it.
Flat & Low-Slope Roofing
Low slope is everywhere in this town once you start looking. Main Street downtown, the older commercial blocks, mid-century additions across the north end, and most of the flat-roofed infill built in the last fifteen years.
Roof Coatings & Sealing
Coatings get oversold in most of the country and undersold here. In a valley seeing 9.42 inches of precipitation a year and 57 days above 90 degrees, a reflective coating does the work it was invented for, and the climate that makes it perform also makes it easy to apply.
Roof Ventilation
Ventilation gets designed backwards in this valley, because nearly all the published guidance was written for humid states. There, attic ventilation is fundamentally a moisture strategy.
Skylights
A skylight is a hole cut through the most weather-exposed surface of a house. On ground that moves it is also a rigid box being asked to stay square while the frame around it does not.
Gutters & Downspouts
Gutter work in this valley is mostly about the edge of the roof and what lands on it. Cottonwood and Siberian elm shed constantly, blowing silt settles into every trough, and the two together set up as a dense crust that our rainfall will never flush out on its own.
Fascia & Soffit
The eave is where a roof meets everything else, and in a dry valley it fails differently from what the internet will tell you. Rot does happen here, but it is never ambient.
Chimney Flashing
If this site has one page that matters more than the rest, this is it. On a valley floor of expansive shale, a masonry chimney and the roof deck it passes through are two structures resting on different foundations, and they do not move together.
Emergency Tarping
Emergency work is a small share of what we do, which is worth saying. This is not a coastal market.
Commercial Roofing
Grand Junction is the commercial hub for a large piece of western Colorado, and the building stock shows it. Retail and medical along the North Avenue and Patterson corridors, older masonry blocks downtown, packing sheds toward Palisade and Olathe, energy service yards up the river at Parachute and Rifle.
Insurance Claim Help
We help with claims, carefully. Documenting damage properly and meeting an adjuster up on the roof is legitimate work.
Commercial low-slope roofing across the Western Slope's regional hub
Grand Junction carries the commercial building stock for a very large region: retail and medical on North Avenue and Patterson, masonry blocks downtown, packing and cold storage toward Palisade and Olathe, and service yards upriver. Low slope dominates the stock, and the perimeter is where it gives out. We survey terminations, coping joints, curb heights and drains before we talk about membrane, then specify by exposure rather than by habit.
- ✓Parapet base detailing with flexible flashing and properly anchored termination bar
- ✓Fully adhered TPO and PVC where corner uplift governs the design
- ✓Tapered polyisocyanurate packages to correct decks framed dead flat
- ✓Reinforced coating restoration for sound membranes with ultraviolet damage
- ✓Curb, drain and scupper surveys with photographs by roof zone
- ✓Walk pads routed where service traffic actually goes
- ✓Scheduled maintenance agreements with two documented inspections a year
- ✓Night and weekend work to keep tenants trading through a reroof

How It Works
- Inspection, inside and out. We start indoors, checking door heads, window corners and interior doors for the seasonal binding and diagonal cracking that mean a building is moving. Then the attic, then the roof, slope by slope. That order stops us from selling a roof to fix a problem that is not in the roof.
- A written scope you can compare. You get dated photographs by slope, a plain-language condition summary, and a scope sorted into urgent work, deferrable work, and work we think you should skip. Flashing, underlayment and metal gauge are itemized separately, so two bids can be laid against each other and actually compared.
- Deck-first installation. Tear-off goes to bare sheathing so we can see it. Delaminated panels get replaced, the deck gets re-nailed, then synthetic underlayment and self-adhered membrane at valleys, eaves and every penetration. New flashing metal throughout, never reused, and hand-sealed rakes where dust may beat the sun to the sealant strip.
- Cleanup, documentation and warranty. Magnetic sweep of the drive and lawn, debris hauled the same day, and photographs of the finished details before the ladders come down. You receive the completed scope, the manufacturer's product documentation and a written workmanship warranty covering flashing and penetrations separately from the shingle field.
What Grand Junction Customers Say
They came out for what I assumed was a full replacement and told me the shingles had eight years left and my problem was the chimney. Cut a reglet, fit new metal in two pieces, and it has been dry through two springs.
Our packing shed roof held water after every storm. Instead of quoting a tear-off they shot the deck for slope, added tapered insulation over the low corner and coated it. Half the price and the ponding is gone.
A door-knocker told me I had hail damage. These folks walked the roof with me, showed me the granule loss was age on the south slope only, and put it in writing. No claim, no pressure, honest invoice for the inspection.
Downtown building, leak at the parapet for years, three contractors had sealed it. They replaced the base flashing and the termination bar properly and explained why the wall and the deck were not moving together. Finally fixed.

Frequently Asked Questions
Does Colorado license roofing contractors?
Not at the state level. Colorado issues no statewide roofing license, which is why so many advertisements here are vague about it. What exists locally is the City of Grand Junction contractor's license, administered by the Mesa County Building Department and required only inside city limits. Roofing sits under the specialty contractor category. Outside city limits you should still be asking for insurance certificates and a permit.
My roof leaks at the chimney every spring. Is the roof failing?
Usually not. A leak that returns on the same seasonal schedule at the same joint is a movement signature. The valley floor is expansive Mancos Shale, the chimney and the roof deck sit on different supports, and when the ground swells they shift relative to one another. Sealed one-piece counterflashing cannot survive that. Two-piece counterflashing cut into a reglet can, because the overlap simply slides.
Should I buy impact-rated Class 4 shingles in Grand Junction?
Probably not, and we will show you why. The NOAA Storm Events Database logged 14 hail reports in Mesa County between 2016 and 2025. Larimer County logged 143 and Weld County 431 over the same decade. The Front Range arithmetic that justifies the upgrade does not carry across the divide. Unless your own carrier offers a discount that pays for it, spend the money on flashing and underlayment.
How long should a roof last here?
Less than the wrapper claims, and rain has nothing to do with why. With 57 days a year at or above 90 degrees and thin air at 4,646 feet, asphalt ages by heat and ultraviolet. South and west planes reach the end well before north ones. We give remaining life as a range per slope, never a single number, because a single number would be a guess.
Do you help with insurance claims?
Yes, and carefully. Colorado law requires a written contract with scope and cost, gives you seventy-two hours to rescind after an insurer denies a claim, and forbids any contractor from waiving or rebating your deductible. We document properly and meet the adjuster on the roof. We also tell people in writing when there is no claim to make, which on this side of the state is often the honest answer.
Which areas do you cover?
Grand Junction, Clifton, Fruita, Palisade, Redlands, Orchard Mesa, Fruitvale, Loma, De Beque and Collbran across Mesa County, and out through Delta, Montrose, Olathe, Cedaredge, Paonia, Hotchkiss and Crawford. Up the river we work Parachute, Battlement Mesa, Rifle, Silt and New Castle, and we travel to Rangely and Meeker. We scope thoroughly on the first visit when the drive is long.
