Spread three roof replacement bids across a kitchen table and the totals can sit thousands of dollars apart for the same house. Most homeowners assume the lowest number is the bargain and the highest one is padded. The real gap usually comes from something else. It comes from what each contractor plans to do once the old shingles are off.
That is why reading the quote matters more than reading the total. Contractors such as The Best Roofing Company, which handles storm repairs and full replacements around the Twin Cities, tend to break out tear off, decking, underlayment and cleanup as separate items. Whoever you hire, a bid written that way is easier to compare. It is also much harder to shortchange later.
Here is a practical way to read any roofing quote, section by section, with a northern winter in mind.
Start With What Comes Off
The first line to check is the tear off. A full tear off strips the roof down to the wood deck. A layover puts new shingles directly on top of the old ones.
Layovers cost less up front. They also hide the deck, add weight, and trap heat that shortens shingle life. Most building codes cap a roof at two layers, and many manufacturers limit their warranties on layovers.
A clear quote names the number of existing layers, confirms a full tear off, and says how debris will be hauled away. If the bid is silent on all three, ask before going further.
The Decking Line Explains Most Price Gaps
Nobody knows the true condition of the roof deck until the shingles come off. Soft plywood, delaminated OSB and old water stains often show up around chimneys, valleys and low edges.
Careful bids handle this with a per sheet price and a stated number of sheets already included. Lowball bids often skip the line entirely. The missing cost then returns as a change order on installation day, when the house is open to the sky and you have no leverage.
Older homes add a twist. Many were built with plank board decking that has gaps between boards. Some shingle manufacturers want a layer of new sheathing over planks before they will honor a full warranty, so ask how the bid treats that.
Ice Barrier and Underlayment Belong in Writing
Ice dams are the classic cold climate roof failure. Snow melts over a warm attic, runs down to the cold eave, refreezes, and backs water up under the shingles.
In regions with a history of ice damming, codes require a self-adhering ice barrier from the eave edge to at least 24 inches inside the exterior wall line. That is the minimum. Many installers also run it up valleys and around skylights, vents and chimneys.
Your quote should say how far the ice barrier extends and where. The rest of the deck typically gets synthetic underlayment, which holds up better than old felt paper if rain arrives mid project.
Ventilation and Flashing Separate Good Work From Fast Work
A roof only lasts as long as the attic beneath it stays cool and dry. Balanced ventilation pairs intake at the soffits with exhaust at or near the ridge. Too little airflow cooks shingles in summer and feeds ice dams in winter.
Flashing is the other quiet budget cutter. Reusing old step flashing along sidewalls or old counterflashing at a chimney saves an hour of labor and invites a leak years later. A strong bid lists new drip edge, new step flashing, and new pipe boots by name.
Questions Worth Asking Before Anyone Signs
A short conversation clears up most of what a written bid leaves vague. These questions work with any contractor.
- What is your Minnesota residential contractor license number, and can I look it up?
- Who pulls the permit, and who schedules the final inspection?
- Will your own crew do the work, or a subcontractor, and who supervises on site?
- What is the price per sheet for replacement decking, and how many sheets are included?
- Which shingle warranty tier applies, and what does your workmanship warranty cover?
- How is payment split, and what is due before work begins?
Write the answers on the quote itself. Two bids built to the same specification are finally worth comparing on price.
When Insurance Pays for Part of the Roof
Hail and wind claims change the rhythm of hiring. After a big storm, door knockers arrive within days, some from out of state, offering free inspections and fast signatures.
The Federal Trade Commission keeps a practical guide on avoiding repair scams after weather emergencies, including how to check a contractor and pay safely. The core advice holds up well. Get local references, avoid large cash deposits, and never sign a contract you have not fully read.
Minnesota adds its own protection. Homeowners who sign a roofing contract that depends on insurance approval generally have a short window to cancel if the insurer denies the claim. Ask any contractor to point to that cancellation language in their agreement.
On the claim side, the National Association of Insurance Commissioners outlines what to do before and after a storm, from documenting damage to working with an adjuster. Photos taken before any tarp or temporary repair go up are often the most useful evidence you will have.
Warranties Are Two Different Promises
A roof carries two warranties, and they cover very different things. The manufacturer warranty covers defects in the shingles and related materials. Enhanced versions often require a certified installer and matching components from the same brand, from underlayment to ridge cap.
The workmanship warranty comes from the contractor and covers installation errors, which cause most early leaks. Its value depends on how clearly it is written and whether the company will still be answering the phone in ten years. Ask for both warranties in writing, along with what voids them.
Reading Past the Bottom Line
The goal is not to find the cheapest roof or the most expensive one. It is to make sure every bid describes the same roof, so price becomes a fair comparison instead of a guess.
If two quotes still differ widely after that, ask each contractor to walk you through their numbers. Most good installers welcome the question. A roof is a layered system, and the layers you never see after installation day are the ones that decide how it handles the next January.
