Every Layer of a Replacement Roof and What It Does
A roof is not just shingles. It is a stack of parts, and each one has a job. If a bid leaves a layer out, the price looks better and the roof performs worse.
Roof deck
- What it is
- The plywood or OSB sheets nailed to the rafters.
- Its job in plain words
- The floor of the roof. Everything else fastens to it.
- Code or standard reference
- IRC R803, deck must be sound and properly supported before covering.
Ice barrier
- What it is
- A self adhering membrane at the eaves that sticks to the deck.
- Its job in plain words
- Blocks water that backs up under shingles when ice forms at the cold overhang.
- Code or standard reference
- IRC R905.1.2, required in areas subject to ice damming.
Underlayment
- What it is
- A synthetic or felt sheet rolled over the whole deck.
- Its job in plain words
- The backup layer. If water gets past a shingle, this sheds it.
- Code or standard reference
- IRC R905.1.1 and ASTM D226 or ASTM D4869 for felt.
Drip edge
- What it is
- Metal angle along eaves and rakes.
- Its job in plain words
- Kicks water off the edge and into the gutter instead of behind it.
- Code or standard reference
- IRC R905.2.8.5, drip edge is required at eaves and rakes.
Starter strip
- What it is
- A sealed first course under the visible bottom row.
- Its job in plain words
- Glues down the bottom edge so wind cannot get under it.
- Code or standard reference
- Required by shingle manufacturer instructions for wind warranty coverage.
Flashing
- What it is
- Metal at walls, chimneys, valleys and skylights.
- Its job in plain words
- Bridges every place the roof stops and something else begins.
- Code or standard reference
- IRC R903.2, flashing required at wall and roof intersections.
Shingles
- What it is
- The visible weather surface.
- Its job in plain words
- First line of defense and the part that takes the sun and hail.
- Code or standard reference
- IRC R905.2, ASTM D3161 or D7158 wind, ASTM D3462 for fiberglass shingles.
Ventilation
- What it is
- Intake at the soffit, exhaust at the ridge.
- Its job in plain words
- Keeps the attic close to outdoor temperature so the deck stays dry.
- Code or standard reference
- IRC R806, one to 150 net free area, or one to 300 when conditions are met.

How Do You Know It Is Time to Replace a Roof?
Age alone does not decide it. These are the signs that a roof has moved past repair. A replacement is the right call when continued repairs cost more over time than starting fresh, or when the roof can no longer protect the house reliably.
- Wear on every slope
- Granule loss, curling or cracking across the whole roof means the system is aging out, not failing in one spot.
- Repeat leaks
- When repairs keep returning to new areas, each fix buys less time and the total cost adds up.
- Widespread storm damage
- Hail or wind damage across several slopes is often more practical to replace than to patch.
- Soft or sagging areas
- A deck that flexes underfoot or sags between rafters points to long-term water or structural problems.
If you are unsure, an inspection with photos and an honest repair-or-replace opinion is the right first step.
Tear-Off or Overlay: Which Is Right?
Some roofs can technically take a second layer of shingles over the first. In most cases, a full tear-off is the better choice. Your inspection will show whether an overlay is even an option. If the existing roof has two layers already, soft decking or failed flashing, tear-off is the only sound choice.
- Tear-off exposes the deck, so soft or damaged boards are found and replaced instead of buried.
- A new layer over an old one adds weight and can telegraph bumps and old damage through the new shingles.
- Many manufacturers limit warranty coverage on overlays, and some building codes restrict how many layers are allowed.
- Overlays cost less up front but leave old flashing and problems in place.

What Should a Roof Replacement Estimate Include?
Two bids are only comparable when they describe the same job. These are the lines to look for. If one bid is missing a line the others include, ask about it. That gap is often the reason a price looks lower.
Decking Allowance
A price per sheet for replacing damaged boards found during tear-off.
Named Materials
The shingle or panel line, color, underlayment and accessories by brand.
Flashing and Ventilation
Whether flashing is replaced and how attic ventilation will be handled.
Permit and Inspections
Who pulls the permit and schedules required inspections.
Warranty Terms
The manufacturer warranty, the workmanship warranty and how each is registered.
What Affects the Cost of a Roof Replacement?
A full roof replacement in Denver typically runs $15,000 to $50,000. Where a home lands in that range depends on a handful of factors. Ask for the estimate to break out each of these so you can see where your money goes.
The Biggest Cost Drivers
Size and pitch: More roof area and steeper slopes mean more material, more labor and more safety setup.
Material: Standard shingles, impact-rated shingles and metal sit at very different price points.
Complexity: Valleys, dormers, skylights and chimneys add flashing work and time.
What is underneath: Extra old layers to remove and the amount of decking that needs replacing.
An itemized estimate shows exactly which of these is driving your number.
What Happens on Roof Replacement Day?
Many homes are torn off and re-roofed in one or two days, weather permitting. Larger or complex roofs take longer. Our crew lead stays in touch through the day, and you will know what was found and what was replaced before the job is done.
- Before the crew arrives
- Move cars out of the driveway, take fragile items off walls and shelves near the roof, and let neighbors know. Protect anything stored in the attic from falling dust.
- Tear-off and deck check
- The old roof comes off, the deck is inspected, and any damaged boards are replaced and photographed.
- Installation
- Underlayment, flashing, ventilation and the new roofing go on, slope by slope.
- Cleanup and walkthrough
- Debris is removed, the yard is swept with magnets for nails, and you walk the finished job and receive closeout photos and warranty details.
For Dan, we coordinated solar panel removal and reinstallation during a full roof and detached garage replacement, completed both structures in one day, and cleaned up thoroughly afterward.

Frequently Asked Questions

Meet The Owner
JJ Hedden, Founder & Owner
JJ Hedden founded Peak to Peak Roofing & Exteriors so Front Range property owners would have a roofer who is still reachable after the truck pulls away. He came up through inspections, claims and installations, so the standards our crews work to are the ones he set on roofs himself.
On a full replacement he reviews the scope before it goes out: decking condition, ventilation balance, ice and water coverage and the flashing details. If a Front Range roof can be repaired instead, he will say so rather than sell a tear off.
