What Shingle Roofing Involves
Shingle roofing means removing your old layers, inspecting the decking, and installing new asphalt shingles with proper underlayment and flashing. We use Owens Corning Duration shingles for their Class 4 impact resistance, GAF Timberline HDZ for their LayerLock technology that seals against wind uplift up to 130 mph, and CertainTeed Landmark Pro for their algae-resistant granules. Each install includes a synthetic underlayment, ice-and-water shield at eaves and valleys, and ridge vents matched to your home’s square footage. We also replace all pipe boots, drip edge, and step flashing to meet Denver’s building code.
Signs You Need Shingle Roofing
Granules collecting in your gutters after a spring hail event means the shingle mat is exposed. Curling or cupping edges indicate the asphalt has aged past its service life. If you see daylight through the roof deck from the attic, the shingles have lost their seal. Dark streaks from algae aren’t just cosmetic — they trap moisture and accelerate granule loss. Missing shingles after a 60-mph wind gust, especially on south-facing slopes, means the nailing pattern has failed. Ice dams along the eaves in February push water under the shingles and rot the decking underneath.
Our Shingle Roofing Process
- Pre-Installation Walkthrough: We walk the roof with you, mark all damaged decking, and photograph every area of concern. You see exactly what we’ll replace before we start.
- Teardown & Deck Prep: We strip the old shingles, remove all nails, and sweep the deck with a magnetic broom. Any rotted plywood gets cut out and replaced with CDX-grade 5/8-inch plywood.
- Underlayment & Flashing: We roll out synthetic underlayment with a 40-year lifespan, install ice-and-water shield at all valleys, eaves, and pipe penetrations, and replace all step flashing with galvanized steel.
- Shingle Installation: We nail each shingle with six nails per strip, offsetting seams by 6 inches per course. All ridges get cap shingles nailed with 2-inch ring-shank nails for wind resistance.
- Cleanup & Inspection: We run a full magnetic sweep of the property, blow off the driveway, and do a final seam-by-seam inspection with you. You sign off only when you’re satisfied.
Cost Considerations in Denver
For a typical 2,000-square-foot Denver home with architectural shingles, you’ll pay between $8,500 and $12,500, or roughly $425 to $625 per square (100 square feet). Three-tab shingles run $6,000 to $9,000 but offer lower wind ratings and shorter warranties. Designer shingles from CertainTeed’s Belmont line cost $14,000 to $18,000 for the same area but give you a slate-like profile with a 50-year warranty. Our quotes include all materials, labor, dump fees, and permit costs — no surprise charges for deck repair or flashing replacement.
Warranty & Insurance
GAF offers a 25-year non-prorated warranty on Timberline HDZ shingles that covers manufacturing defects and algae staining. Owens Corning’s Duration line carries a 30-year limited warranty that transfers once to a new owner within the first 10 years. CertainTeed’s Landmark Pro includes a 50-year warranty with a 10-year SureStart period that covers labor and materials. We register your warranty with the manufacturer within 30 days of completion and provide you with the certificate. If you’re filing a storm-damage claim, we work directly with your adjuster to document hail strikes and wind damage so you get maximum coverage.
Why Choose Denver Roofing Team for Shingle Roofing in Denver?
Denver sits at 5,280 feet above sea level, which means UV radiation is 20 percent stronger than at sea level — that’s why we only install algae-resistant, high-granule shingles. The 2017 hailstorm that hit Capitol Hill and Five Points caused over $2.3 billion in damage, and we replaced roofs on 140 homes in that corridor alone. Our crews live in the neighborhoods they work — Washington Park, Cherry Creek, Highland, Baker — so we understand the specific wind patterns and freeze-thaw cycles that affect mid-century brick ranches and Victorian bungalows. We’re a local Denver County contractor, not a franchise, and we show up when we say we will.
Signs You Need Shingle Roofing
Granules in Gutters
After a Denver hailstorm, loose granules in your downspouts mean the shingle’s protective coating is compromised. Without that layer, UV rays degrade the asphalt and shorten your roof’s lifespan by years.
Curling or Cupping Shingles
Shingles that curl at the edges or cup upward have lost their sealant bond, often from Denver’s extreme temperature swings. This exposes the nail heads to moisture and leads to leaks within six months.
Daylight Through the Deck
If you see light coming through the roof boards from your attic, the shingles have worn through completely. This is a direct path for rain and snowmelt to enter your insulation and drywall.
Missing Shingles After Wind
A 60-mph gust in Highland or Baker can rip off individual shingles if they were under-nailed. Missing shingles leave the underlayment exposed, and a single storm can turn a small gap into a large leak.
Ice Dams at the Eaves
Denver’s freeze-thaw cycles create ice dams that force water under the shingles and into your attic. If you see icicles hanging from the gutter line, the attic ventilation and ice-and-water shield need replacement.
Dark Streaks on South Slopes
Algae growth on south-facing slopes is common in Denver’s sunny climate. Those black streaks trap moisture and accelerate granule loss, reducing the shingle’s impact resistance during the next hailstorm.
