Roof replacement in Denver, done once, done right.
A new roof is a 25–50 year decision. Here's exactly what it costs, how long it takes, what has to be included, and why the crew that installs it matters as much as the shingles.
How much does a roof replacement cost in Denver?
A typical asphalt shingle roof replacement in Denver costs $9,000–$22,000. Most 2,000+ sq ft homes land between $15,000 and $22,000. Metal and tile run higher. If hail is involved, insurance often covers replacement minus your deductible.
What moves the number: roof size and pitch, number of layers to tear off, material choice, and complexity (valleys, skylights, chimneys). Rough guide for asphalt shingle systems on Front Range homes:
| Home / roof size | Typical range | Timeline |
|---|---|---|
| Smaller ranch (~1,500 sq ft roof) | $9,000–$13,000 | 1 day |
| Typical two-story (~2,000–2,500 sq ft roof) | $13,000–$18,000 | 1–2 days |
| Larger / steep / complex (3,000+ sq ft roof) | $18,000–$25,000 | 2–3 days |
| Tile or metal systems | Quoted per roof | 3–5 days |

What's included in a Bailey replacement?
The first sentence answer: everything the manufacturer requires for full warranty coverage, plus the Colorado-specific details a lot of bids quietly skip. Specifically:
- Full tear-off to the deck — we don't overlay new shingles on old ones
- Deck inspection with photos; rotted decking replaced and documented
- Ice-and-water shield at eaves and valleys, where Colorado freeze-thaw does its damage
- Synthetic underlayment (not old-school felt)
- New drip edge, pipe boots, and flashing — reusing old flashing is how leaks happen
- Ventilation sized for attic heat at altitude — ridge exhaust, plus low-profile rooftop intake vents when soffits can't pull enough air
- Your choice of Owens Corning, GAF, or CertainTeed shingle system
- Permits pulled and city inspection passed
- Daily cleanup, full haul-away, and a magnetic nail sweep of your yard and driveway
- Manufacturer warranty registered in your name, paperwork in hand
Which shingles hold up in Colorado?
For most Front Range homes, an architectural asphalt shingle from one of the big three — Owens Corning Duration, GAF Timberline HDZ, or CertainTeed Landmark — is the right balance of cost, look, and durability. We install all three; as an Owens Corning Preferred Contractor we can offer enhanced OC warranty tiers, which is why Duration is our most common recommendation.
Because we live in the hail belt, the upgrade conversation that actually matters is Class 4 impact resistance (UL 2218, the highest rating). Class 4 shingles cost roughly 10–20% more in materials, and many Colorado insurers discount premiums for them — over a decade, the discount often pays for the upgrade. Recent Class 4 jobs from our own books: Owens Corning Duration Storm in Driftwood on a golf-course home in Heritage Eagle Bend (Aurora), GAF ArmorShield II on a craftsman two-story in Broomfield, and Owens Corning Duration Storm in Onyx on a brick ranch in Cheyenne, Wyoming — the north end of our service range.
The honest framing
Not every roof needs replacing. If your roof is 8–15 years old and structurally sound, a GoNano coating at roughly one-third the cost may buy it 10–15 more years. And if a repair genuinely fixes it, we'll quote the repair. We'd rather earn the replacement in five years than push it today.
What warranty do you actually get?
Up to 50 years on materials with Owens Corning Duration systems, plus Bailey's own 10-year workmanship guarantee. The distinction matters: material warranties come from the manufacturer, but installation errors — the cause of most roof failures — are only covered by the contractor's workmanship warranty.
That's the practical reason to hire a certified contractor. Manufacturer certifications like Owens Corning Preferred exist because the companies that make the shingles audit who installs them well. And a workmanship guarantee is only as good as the company still being around — we've been at the same Denver address since 2010.

How long does a roof replacement take?
Most asphalt shingle replacements: 1–2 days from tear-off to cleanup. Tile, metal, steep-pitch, or multi-level roofs: 3–5 days. We confirm the schedule in writing before we start.
Are Class 4 shingles worth it in Colorado?
Usually yes. The Front Range is hail country, Class 4 is the highest impact rating, and many Colorado insurers discount premiums for it — which often pays back the 10–20% material upcharge over time. Ask your agent for their exact discount before you decide.
Do you handle the insurance claim if hail caused it?
Yes — documentation, adjuster meeting on the roof, and scope review are part of the job. See the full hail damage claims page for how the process works and what Colorado law says about deductibles.
Can I stay home during the work?
Yes, most people do. Expect real noise from roughly 7am to 5pm on install days and keep pets somewhere calm. We tarp around the house, protect landscaping, and sweep for nails before we leave.
Tear-off or overlay — does it matter?
It matters. Overlays trap heat, hide deck rot, void most manufacturer warranties, and cost more to remove later. We tear off to the deck every time — it's the only way to know what we're building on.
