A roof replacement covers far more than the shingles you see from the driveway. A complete job means tearing off the old roofing, inspecting the deck underneath, installing new ice and water barrier, underlayment, drip edge, flashing, shingles and ridge cap, then cleaning the property down to the last nail. When homeowners ask what's included in a roof replacement, the honest answer is that it depends on what the contractor wrote into the proposal, which is exactly why two bids on the same house can differ by thousands of dollars.

Minnesota weather adds challenges that warmer states never deal with. Our winters mean certain components are not optional extras here, they are code. Knowing which is which makes it much easier to tell whether an estimate is thorough or not.

An Overview of What to Expect from a Roof Replacement

• Almost always included: tear-off and disposal, deck inspection, ice and water barrier at the eaves, underlayment, drip edge, new flashing, shingles, ridge cap, cleanup and permit.
• Usually priced separately: replacing rotted decking, gutter work, new soffit intake or a cut-in ridge vent, skylights, chimney masonry.
• What often gets overlooked: attic ventilation. Shingle manufacturers tie warranty coverage to balanced intake and exhaust, so a bid that ignores your attic can quietly cost you years of protection.

What Materials Are Usually Used?

A good proposal reads like a parts list. Every layer of the roof system should be named, not bundled into one line that says "install new roof."

Shingles. Architectural asphalt shingles are the standard choice on Twin Cities homes because they hold up well against hail, wind and freeze-thaw cycling. Metal is an option on some rooflines. Either way, your estimate should be specific, naming the manufacturer, product line and color.

Ice and water barrier. This is the self-adhering membrane that goes directly on the deck along the eaves. In Minnesota it is required, and it needs to run from the roof edge to a point at least 24 inches inside the exterior wall line. It is your main defense when water backs up under shingles behind an ice dam. The ice and water shield should also run through valleys and around chimneys.

Underlayment. Above the ice barrier, synthetic underlayment covers the rest of the deck. It sheds water during installation and gives the roof a second layer of protection if wind lifts a shingle years down the road.

Drip edge. Metal trim along the eaves and rakes that pushes runoff clear of your fascia and into the gutter. Leaving it off leads to rotted fascia board, which is a far bigger repair than it sounds.

Flashing. Step flashing at walls, valley metal, pipe boots and chimney flashing. Reusing old, brittle flashing is one of the most common shortcuts in the trade and a frequent source of leaks on a brand new roof. Ask directly whether flashing is being replaced or reused.

Ridge cap and fasteners. Ridge cap shingles finish the peaks and hips. Nails should be specified as roofing nails driven to the manufacturer's pattern, because fastener placement is what holds a roof down in a straight-line wind event.

Ventilation components. Ridge vent, box vents or a turbine, depending on your roof design. Swapping out existing vents is normally part of the base scope.

What the Crew Actually Does in a Roof Replacement

Materials are only half the estimate. The rest is labor, and it breaks into four stages.

Tear-off and disposal. Crews strip the old roofing down to the wood deck, load it out and haul it away. Dumpster rental and landfill fees are usually folded into this line. On most Minnesota homes a full tear-off is the right call rather than layering new shingles over old, because covering the deck hides whatever damage is sitting underneath it.

Deck inspection. With the old roofing gone, the deck gets walked and checked for soft spots, delamination and old leak damage. This is the stage where surprises show up, which is why a good contractor calls you before replacing anything.

Installation. Ice barrier, underlayment, drip edge, flashing, field shingles, ridge cap and vents, installed in that order to manufacturer specification. If a manufacturer system warranty is part of your proposal, both the installation sequence and the accessory products matter.

Cleanup and walkthrough. Debris hauled off, gutters cleared, and a magnetic sweep of the lawn, driveway and landscaping beds for nails. You should get a walkthrough at the end, not just an invoice.

Permit. Reroofing generally requires a permit and inspection from your city. The contractor is required to pull this in practically every case. If a bidder suggests skipping the permit to save money, that's your sign to look for another roofing company.

What Minnesota Code Requires for Roof Replacements

This is where generic roof replacement checklists fall short for homeowners here.

Ice and water barrier at the eaves is not an upsell in Minnesota, it is a code requirement driven by our frigid winter temperatures. If one bid comes in noticeably cheaper and the ice barrier line is missing or covers a narrower strip than the code minimum, you are not comparing equal roofs.

Attic ventilation works the same way. Minnesota code sets a minimum net free vent area based on attic square footage, and it is meant to be balanced between intake at the soffit and exhaust at the ridge. Plenty of older Blaine and Coon Rapids homes have decent ridge exhaust and almost no working intake, usually because insulation got pushed into the soffit bays at some point. A new roof installed over that setup traps heat and moisture, cooks the shingles from below and raises your odds of ice dams during the colder months.

Ventilation is also the quiet condition buried inside most manufacturer warranties. If shingles fail early and the cause traces back to trapped attic heat rather than a manufacturing defect, coverage can be reduced or denied. That is why a thorough estimate mentions your attic, not just your roof.

Please note, the state of Minnesota sets the base requirements for roof replacements, which cities manage and enforce locally. Individual cities govern permit issuance, inspections, and processing rules that fit within or add to the state baseline. Specifications can vary by city. Working with a contractor who knows how to navigate the wide range of local codes across the Twin Cities and the surrounding suburbs is key.

Costs That Usually Get Priced Separately

Some charges cannot honestly be quoted before the old roof comes off.

Decking replacement. Rotted or delaminated sheathing is nearly always billed per sheet, with material and labor included in that rate. Ask what the per-sheet price is up front so it is not a surprise conversation.

Gutters and downspouts. Separate scope, though it is a sensible time to handle it since the roof edge is already open. Read more about our gutter installation and repair work.

Structural ventilation work. Replacing existing vents is standard. Cutting a new ridge slot, adding soffit intake vents or installing baffles to clear blocked bays is additional work.

Skylights, chimney masonry and siding repair. All commonly discovered during a roof project, all priced on their own.

How Insurance Affects Roof Replacement Projects

Storm jobs run on different rules. After hail or high wind, the scope is driven by the insurance adjuster's estimate, which is written as line items: shingles, ice barrier, drip edge, ridge vent, steep and high charges, and so on.

Two things are worth knowing. Adjusters sometimes miss items, and supplements exist precisely so a contractor can document what was left out and get it approved. And your out-of-pocket cost on an approved claim is normally your deductible, so anyone offering to make that disappear is offering to commit fraud on your behalf.

If a storm just moved through your neighborhood, a free storm damage roof inspection before you file tells you whether you have damage worth a claim.

Warranties That Should Be in Place

Material coverage from the manufacturer. Length depends on the shingle line and on whether your contractor is certified to install the full system. Certified installers can often register enhanced coverage that a non-certified crew cannot offer at all. Ask which warranty your specific shingle carries and what registration requires.

Workmanship coverage from your contractor. This covers installation errors. One year is the low end of the industry, and longer terms are common with established local contractors. The terms should be in writing, with a clear answer to who you call and how a claim works.

How to compare two roofing bids

Line the proposals up side by side and check for these:

• Are all materials named by manufacturer and product line, with quantities?
• Is flashing listed as new, or is it silent on the subject?
• Does the ice barrier coverage meet the Minnesota minimum?
• Are labor, disposal, permit and cleanup itemized or lumped together?
• Are both warranties spelled out, with terms in years?
• What is the timeline, and when does payment come due?
• Is the contractor licensed and insured, with a certificate you can actually see?

If one bid comes back well below the others, one of these answers is usually where the difference is hiding.

Questions worth asking before you sign

• What exactly does this price include, and what could add to it once you're on the roof?
• What is the per-sheet charge if the decking needs replacing?
• Are you evaluating attic intake and exhaust as part of this bid?
• Do you pull the permit and schedule the inspection?
• Who supervises the crew on site, and how do I reach that person?
• What does your cleanup process look like?
• How long will my roof take, and what happens if weather moves in mid-job?

Know What Your Roof Replacement Entails before You Sign

Before you sign, you should be able to say out loud what your roof replacement entails: the materials going on, the labor included, the warranties you end up holding and the costs that could still come up. A contractor who welcomes those questions is usually the one who has good answers.

Select Exteriors has been replacing roofs out of Ham Lake since 2010, working across Blaine, Coon Rapids, Andover and the Twin Cities metro. Every estimate we write spells out the materials, the labor and anything we think could turn into an added cost once we are on the deck.

Frequently Asked Questions

What does a roof replacement include from start to finish?

Tear-off of the old roofing, inspection of the wood deck, installation of ice barrier, underlayment, drip edge, flashing, shingles, ridge cap and vents, then debris removal and a nail sweep. Most single-family metro homes are a one to two day job, weather permitting.

Do roofers replace flashing during a roof replacement?

On a properly scoped job, yes. Step flashing, valley metal and pipe boots get replaced because old metal is usually corroded or bent from the original install. Confirm it is written into your estimate rather than assuming.

Is decking repair part of a roof replacement quote?

Rarely. Nobody can see the condition of the plywood or OSB until the old roofing is off, so most contractors quote a per-sheet rate for whatever replacement turns out to be needed.

Is ice and water shield required in Minnesota?

Yes. Minnesota's climate triggers the ice barrier requirement, and it must extend from the roof edge to at least 24 inches inside the exterior wall line. Any Minnesota roof replacement estimate should include it.

Why does my shingle warranty depend on attic ventilation?

Manufacturers expect balanced intake and exhaust so heat and moisture are not trapped against the underside of the deck. Without it, shingles age from below, and if a failure traces back to poor airflow rather than a product defect, coverage can be reduced or denied.

Can I stay home while the work happens?

Yes, though it is loud. Move vehicles out of the driveway and clear items away from the perimeter of the house before the crew arrives.
