Roof Replacement in Denver, CO

When a Denver roof is past patching — storm-battered, curling, or simply worn out — Summit Peak Roofing installs a complete, code-current replacement built for Front Range weather. We tear off to the deck, fix what’s underneath, and install GAF architectural shingle systems that carry the strongest warranties in the industry.

What a Summit Peak roof replacement includes

• Complete tear-off down to the roof deck — no shingling over old layers
• Deck inspection and replacement of any rotten or soft sheathing
• Synthetic underlayment and ice-and-water shield in valleys and eaves
• New flashing, pipe boots, and ventilation
• GAF Timberline® HDZ architectural shingles in the color you choose
• Full magnetic nail sweep and site cleanup — we leave it cleaner than we found it
• Manufacturer and written workmanship warranty

How it works

1. Free inspection — we climb up, photograph the roof, and show you exactly what’s going on.
2. Written estimate — clear scope and price, plus insurance-claim help if it’s storm damage.
3. Materials & color — pick your shingle line and color; we order and schedule.
4. Tear-off & install — most homes are done in one to two days.
5. Final walkthrough — we clean up, sweep for nails, and walk the finished roof with you.

Frequently asked questions

How long does a roof replacement take?

Most Denver-area homes are torn off and re-roofed in one to two days, weather permitting. Larger or steeper roofs can take longer, and we’ll give you a realistic timeline in your estimate.

How much does a new roof cost in Denver?

It depends on the size, pitch, and material of your roof. We give free, no-obligation written estimates — and if your roof was damaged by hail or wind, insurance often covers most of the cost.

Do you help with insurance claims?

Yes. We document the damage with photos, meet your adjuster on site, and make sure the approved scope actually covers a proper replacement. We never ask you to commit before your claim is settled.

What shingles do you install?

We install GAF Timberline HDZ architectural shingles as our standard system. As a GAF Master Elite contractor, we can register enhanced manufacturer warranties most roofers can’t offer.
