Why Choose a Re-Roofing in Denver?

Roof replacement specialists first — we're not a general contractor who also does roofs
Denver's high-altitude UV and temperature swings accelerate shingle aging; we know exactly what to look for and when a repair no longer makes sense
Full tear-off and decking inspection on every replacement — no hidden rot or compromised sheathing gets covered up on our jobs
We pull all required Denver building permits and schedule both the mid-roof and final inspections so you're fully code-compliant without the paperwork headache
Straight talk on timeline and cost: aging-roof replacements are planned projects, not emergencies — and we treat them that way

A building permit is required for any roof replacement in Denver — the city mandates permits for residential roofing work exceeding 10% of the roof area or two roofing squares (200 sq ft), whichever is smaller; a full replacement always meets this threshold
Denver requires two mandatory inspections: a mid-roof inspection after underlayment is installed (before it's covered) and a final inspection once work is complete — your contractor must schedule both through Denver's e-permits system
All asphalt shingles must meet Class A fire rating; Denver also requires drip edge flashing on all eaves and rakes, and proper balanced attic ventilation per IRC R806.2
Denver code allows a maximum of two roofing layers — if your existing roof already has two layers, a full tear-off to the deck is required before new material can be installed
Permit requirements and code details do evolve — the city updated its residential roofing permit rules as recently as April 2024, so confirm your specific project's requirements with the Denver Community Planning and Development department or ask us to walk you through the current requirements before work begins

Rules like these change often and vary by lot — the fastest way to know what applies to your property is to ask.
