Roofing Services We Offer
Asphalt Shingle Roofing
Durable, cost-effective shingle roofing for most residential homes.
Learn More →New Roof
There's a specific kind of relief that comes with having a new roof over your head in Denver — no more watching the ceiling when snow starts to melt, no more wondering if this is the winter the old one finally gives out. A new roof means starting fresh with a clean, finished look that you know is solid, properly ventilated, and built for Colorado's climate. Done right, it's something you genuinely won't have to think about for decades, which for most homeowners is the whole point.
Learn More →Roof Replacement / New Roof
A roof replacement with Summit Line is a full-scope project, not a patch job dressed up with new shingles. Every replacement begins with a complete tear-off down to the deck, followed by a thorough sheathing inspection to identify any soft spots, rot, or moisture damage that needs to be addressed before anything goes back on top. From there, we install code-compliant underlayment, flashing, drip edge, and your chosen finish material — whether asphalt, metal, or tile — and manage the City of Denver's required mid-roof and final inspections from start to close, with workmanship covered under warranty.

What's Bringing You to a Roofing Project?
Aging Roof Past Its Prime
Your roof has been doing its job for fifteen, twenty, or more years under Denver's high-altitude sun and wide temperature swings — and it's starting to show it. Worn shingles, granule loss, or a slow minor drip aren't emergencies yet, but they're the roof's way of telling you the clock is running. Replacing it on your schedule, before a failure forces your hand, is almost always less expensive and less stressful than the alternative.
Getting Ready to List or Sell
A fresh roof is one of the first things a home inspector flags and buyers notice in Denver's competitive market. If your current roof's age is going to show up on an inspection report, replacing it before listing puts you in control of the conversation — and the price.
New Homeowner, Unknown History
You bought the house and inherited the roof — and you're not entirely sure how old it is or how well it was maintained. A professional inspection will tell you what you actually have, and if replacement is on the horizon, it's better to know now than to find out on a cold February night.
Energy Costs That Keep Climbing
An older roof with degraded insulation value and poor attic ventilation can quietly add to your heating and cooling bills year-round. A properly installed replacement with code-compliant ventilation and modern materials makes a real difference in how hard your HVAC system has to work through Denver's cold winters and sunny summers.
Something Else Brought You Here
Maybe you're not sure yet what you need — just that the roof has been on your mind and you want a straight answer from someone who knows Denver homes. That's a completely reasonable place to start, and an inspection is a low-commitment way to get clarity.

- 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

Colorado Roofing Permits, Simplified
- 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
Permit requirements vary by project and change over time — the fastest way to know what applies to your property is to ask.

My roof is about 18 years old and has a few worn spots but no major leaks yet. Do I really need to replace it now?
Asphalt shingles at Denver's altitude typically age faster than their rated lifespan suggests, thanks to intense UV exposure and wide temperature swings. An 18-year-old roof showing visible wear is often within a few years of failure — and the cost difference between a planned replacement and an emergency one (interior water damage, ruined insulation, rushed scheduling) is substantial. A professional inspection will tell you whether you're in 'monitor closely' or 'replace soon' territory, but waiting until you have a serious leak is rarely the cheaper path.
How do I know if my roof needs full replacement versus a repair?
The deciding factors are usually age, the extent of wear, and how many layers already exist. Denver code only allows two roofing layers — so if your home already has two, a repair isn't a long-term option anyway. More broadly, if worn areas are widespread rather than isolated, or if the underlying sheathing has moisture damage, repairs tend to be a short-term fix that delays the inevitable. We'll give you an honest assessment of which makes financial sense for your specific roof.
What does a roof replacement project actually look like from start to finish in Denver?
For a planned replacement on an aging roof, the process starts with a thorough inspection and material selection, then permit application through Denver's e-permits system. On installation day, we do a full tear-off, inspect and address any damaged decking, install underlayment and new material, and then schedule both the required mid-roof and final city inspections. Most residential replacements in Denver are completed in one to two days of active work, with the permit and scheduling process happening around that.
