“What does a new roof cost?” is the first question every homeowner asks, and the honest answer starts with a range, not a number. This guide breaks down what drives that range in the Denver metro, so when the bids land on your kitchen table you can read them like a contractor instead of guessing.
The short answer
For a typical Denver-area single-family home, a full architectural asphalt shingle replacement generally lands in the low five figures — smaller ranches come in under that, large two-stories with complex rooflines above it. Standing-seam metal runs roughly twice asphalt. Concrete tile sits between metal and asphalt on material cost but often needs structural review, since tile weighs several times what shingles do.
If a bid comes in dramatically under that territory, something is missing from it: usually decking allowances, proper flashing replacement, disposal fees, or the permit.
What actually drives the price
Roof size and complexity. Roofers price in “squares” (100 square feet). But two 25-square roofs can differ by thousands: hips, valleys, dormers, and skylights all add cutting, flashing, and labor time. Pitch matters too — anything steep enough to require harnessing slows production and raises the labor line.
Tear-off layers. Every existing layer adds tear-off labor and disposal tonnage. Denver’s older neighborhoods are full of roofs with two layers (the code maximum); removing both is the right call, and it costs more than removing one.
Decking condition. Under old roofs — especially pre-war homes with plank decking — expect some replacement. Good contractors write a per-sheet price into the contract up front so decking never becomes a mid-project surprise. If a bid is silent on decking, ask why.
Material class. Builder-grade 3-tab shingles still exist, but in Hail Alley they’re a false economy. Class 4 impact-resistant architectural shingles cost moderately more per square and many Colorado insurers discount premiums for them — the upgrade frequently pays for itself in avoided deductibles and premium savings.
Ventilation and accessories. Ridge vents, intake vents, ice and water shield, drip edge, pipe boots, and flashing are where quality roofs are actually made. They should appear as line items, not vanish into a lump sum.
How to compare bids
Line up bids component by component, not bottom line by bottom line:
- Tear-off — how many layers, and is disposal included?
- Decking — is there a per-sheet replacement price in writing?
- Underlayment — synthetic or felt? Ice and water shield where?
- Shingle spec — exact product name and impact class, not “30-year shingle.”
- Flashing — replaced or reused? “Reused” is the wrong answer at replacement time.
- Ventilation — is the intake/exhaust balance addressed at all?
- Warranty — manufacturer term and the contractor’s own workmanship term, in writing.
Insurance changes the math
If your replacement stems from hail or wind damage, your out-of-pocket cost may be your deductible rather than the full price — see our guide to how roof insurance claims work in Colorado for the full process. Be aware that Colorado law (SB 38) prohibits contractors from paying or rebating your deductible; anyone offering to is telling you how they do business.

A range is where budgeting starts, but your roof deserves its own math. A free inspection gives you a line-item quote within 24 hours — measured, photographed, and priced for your actual roof rather than a metro average.
