Questions to Ask Your Roofing Contractor (Wisconsin Guide)
Updated: Oct 12
Before you sign, ask any roofing contractor about insurance, ownership, manufacturer certification, what the estimate includes, who pulls the permit, and how long the workmanship warranty lasts. The questions below explain why each one matters and what a good answer sounds like.
But not all roofing companies offer the same level of professionalism, service, or value. Before signing your roofing contract, here are the questions to ask your next roofing contractor.
Is My Roofing Contractor Licensed and Properly Insured?
Ask this question first, as it is one of the most important. If a contractor doesn’t have proper insurance and something goes wrong, like a worker getting injured or a major water intrusion during installation, you, the homeowner, could be held financially responsible.
Always ask for proof of insurance and make sure it’s up to date. In Wisconsin, contractors who work on one- and two-family homes are expected to hold a state Dwelling Contractor credential, which you can look up through the Wisconsin Department of Safety and Professional Services.
Is It Better to Hire a Local Roofing Contractor?
Local roofing companies have more at stake.
They live and work in the same communities as their customers, which means reputation, follow-through, and long-term service actually matter.
Roofing is not a one-day transaction.
Local contractors understand Wisconsin weather, local permitting, and neighborhood expectations, and they are still around when you need service, documentation, or warranty support years later. This is why we recommend selecting a local roofing company.
It is also worth understanding who actually owns the company you are hiring. Many national brands and franchises market themselves as local, but are owned by large holding companies or private equity firms. That ownership structure can influence pricing, sales pressure, and long-term accountability.
When evaluating whether a contractor is truly local, ask:
Who owns the company?
Where is their office located?
Will the same team handle service if issues arise later?
Sun Vault Roofing is independently owned, Wisconsin-based, a member of Dane Buy Local, and maintains a rating with the Better Business Bureau.
What Roofing Certifications Should a Contractor Have?
Roofing manufacturers offer certifications to identify contractors who meet high standards for product expertise, installation quality, and business ethics. For example, CertainTeed’s contractor credential program includes:
Shingle Quality Specialist™
Master Shingle Applicator™
ShingleMaster™
SELECT ShingleMaster™ (top-tier)
Ask what certification level your contractor holds and how that compares to the available options. Sun Vault Roofing is a SELECT ShingleMaster™ - CertainTeed’s highest designation. This allows us to offer CertainTeed’s SureStart™ PLUS 3-Star Warranty with up to 50 years of coverage on materials, labor, tear-off, and disposal, as part of our overall Sun Vault One Vault Warranty protection package. Fewer than 1% of roofing contractors nationally hold this distinction.
What Roofing Materials and Brands Will Be Used on My Home?
Make sure your contractor uses an established brand such as CertainTeed, GAF, or Owens Corning. At Sun Vault Roofing, we use shingles manufactured by CertainTeed, one of the most respected names in the industry, with over 100 years of experience. Many of their products are manufactured domestically. A reliable contractor will also offer strong, long-term warranties that stand behind the materials used.
Is Metal Roofing Worth Considering in Wisconsin?
Asphalt shingles are the default choice for most Wisconsin homeowners, but roofs can be made from all kinds of materials. That said, if a contractor recommends something other than asphalt, they had better have a good reason. Metal roofing has become something of a marketing phenomenon in the past decade. But our stance is that metal's a poor choice for most Wisconsin roofs when you consider the upfront cost and time value of money.
Some of the most expensive roofing failures start in places homeowners never see once the job is finished. The next questions cover those hidden components, which are often skipped in low-cost estimates.
Will My Old Shingles Be Removed or Covered Over?
Skipping the tear-off step is cheaper, but it comes with serious consequences. Roofs installed over old shingles won’t last as long, and manufacturer warranties are typically invalidated. There are very few situations where skipping the tear-off is recommended, and a trustworthy contractor will explain your best option honestly.
Will Flashing and Edge Metals Be Replaced With the Roof?
Flashing refers to metal installed around chimneys, vents, and valleys to prevent water infiltration. Edge metals protect the roof's perimeter. These components are essential to a watertight roof.
Ask whether your contractor plans to replace these materials. In most cases, the answer should be yes, unless they’ve been thoroughly inspected and are in excellent condition.
If a contractor recommends leaving them in place, they should be able to explain why and confirm they’re still expected to last the full lifespan of your new roofing system. Otherwise, you risk premature leaks, costly repairs, and problems with warranty coverage.
How Thorough Is Your Roof and Attic Inspection Process?
Make sure the contractor will get on the roof for their inspection. A proper inspection should go beyond the surface. In addition to checking shingles and flashing, a reputable contractor will evaluate the attic ventilation, roof decking, and the overall structure for signs of wear, moisture buildup, or poor airflow.
Why does attic ventilation matter?
Ventilation is especially important. Without it, heat and moisture can build up in your attic, shortening the life of your roof and potentially causing mold or rot. Ask whether your contractor will check intake and exhaust vents, assess airflow, and make recommendations for improvement if needed.
Ventilation is not optional, and it is not just a comfort issue. We’ve inspected roofs that failed in as few as 5-10 years because attic airflow was never properly evaluated during replacement. When heat and moisture are trapped, it can lead to condensation on attic framing, mold growth, ice damming, and premature shingle failure, even when high-quality materials were used.
Ask your contractor to explain how they evaluate intake and exhaust balance, not just whether vents exist. A new roof installed over a poorly ventilated attic is still a compromised system.
Should the inspection include soffit and fascia?
A truly thorough inspection should also include soffit and fascia. These areas support your gutters, influence attic ventilation, and are common entry points for moisture and pests. If soffit or fascia boards are rotted, sagging, or compromised, installing a new roof on top of them can shorten the lifespan of the entire system. A reputable contractor should identify these issues early and explain whether repairs are necessary before roofing work begins.
What Should a Roofing Estimate and Contract Include?
A professional roofing estimate should clearly explain what is being done, how it will be done, and what happens if conditions change. Anything less creates room for confusion or unexpected costs.
At a minimum, your written estimate should include a detailed scope of work, specific materials and product lines, tear-off and disposal plans, ventilation and flashing details, permit handling, project timeline, and payment structure. Vague one-page quotes or verbal estimates often leave out critical components that later reappear as added charges.
The contract should also explain how change orders are handled, what warranties apply, and who is responsible if issues arise after installation. If a contractor can’t walk you through their estimate line by line, that’s a sign they may be cutting corners elsewhere too.
What Roof Replacement Financing Options Do You Offer?
If you’re not paying cash, ask how financing works and who is actually providing the loan. A reputable contractor should be transparent about whether prequalification affects your credit score, whether there are prepayment penalties, and what steps trigger a hard inquiry.
At Sun Vault Roofing, homeowners can quickly and conveniently explore roof financing options and prequalify online in only minutes with an entirely digital experience.
We also encourage customers to compare that convenience against alternatives like a HELOC through their local bank or credit union, as lower rates may be available and there are potential tax advantages.
What Does My Roofing Warranty Actually Cover?
Roofing warranties vary widely.
And honestly . . . a lot of it is just marketing jargon.
For something as critical as your roof, the terms matter far more than the headline. A meaningful roofing warranty should clearly define what is covered, for how long, and who is responsible if something goes wrong.
Homeowners should expect a complete warranty discussion to address three distinct areas:
1. Roofing manufacturer coverage (materials and defects)
This covers manufacturing defects in the shingles themselves. Many warranties marketed as “lifetime” are limited and prorated over time, meaning coverage decreases as the roof ages. Others may cover materials only, excluding labor, tear-off, or disposal.
2. System coverage (how components work together)
A roof is a system, not just shingles. Coverage may or may not include underlayment, flashing, starter strips, ridge caps, and ventilation. If these components fail or were installed incorrectly, some warranties offer no protection at all.
3. Workmanship coverage (installation quality)
Manufacturer warranties do not cover installation errors. That responsibility falls entirely on the contractor. Most roofing companies offer 5–10 years of workmanship coverage, and some offer none at all. Once that period expires, any installation-related issues become the homeowner’s responsibility.
When reviewing warranties, always ask:
Is coverage prorated or non-prorated?
Does it include labor, tear-off, and disposal?
How long is it transferable to a future homeowner?
What conditions (ventilation, inspections, certifications) are required to keep it valid?
A strong warranty is specific, written, and balanced between manufacturer protection and installer accountability.
For comparison, the Sun Vault One Vault Warranty includes:
CertainTeed SureStart™ PLUS 3-Star system warranty
Up to 50 years of non-prorated coverage on materials and labor for manufacturing defects
Tear-off and disposal included if shingles must be replaced due to a covered defect
Transferable coverage for 15 years to the next homeowner
A 20-year Sun Vault Roofing workmanship warranty, covering installation-related issues
This level of coverage is not typical across the industry, particularly for workmanship, where most contractors limit coverage to 5–10 years. Learn more about the Sun Vault One Vault Warranty and how to read any roofing warranty.
Will You Pull Roofing Permits and Schedule Inspections?
Roofing permits protect homeowners, even when they feel like paperwork.
In Madison and many other Wisconsin communities, roof replacements require a permit and inspection. A reputable contractor should always pull the permit for you and close it out properly.
We’ve seen what happens when that doesn’t occur. A friend of ours backed out of buying a Madison home after discovering a recently replaced roof had no permit on file. With no inspection or public record, there was no way to verify the work.
Unpermitted roofing can complicate home sales, insurance claims, and warranties. The correct answer to this question should be simple:
“Yes, we’ll pull the permit and handle the inspections.”
Anything else exposes you to unnecessary risk.
How Will My Roofer Communicate During the Project?
Roofing projects in Wisconsin rarely go exactly as planned. Weather shifts, material availability, and hidden conditions can affect timelines or scope. That’s why communication matters just as much as craftsmanship.
Why can decking replacement change the price?
One of the most common surprises during a roof replacement is plywood decking replacement. Beneath your shingles is waterproof underlayment, and beneath that are sheets of plywood fastened to your attic rafters. Over time, especially near the end of a roof’s life, that decking can become damp or rotten. Shingles cannot be installed on wet or deteriorated plywood. Doing so violates building code, voids manufacturer warranties, and puts contractor certifications at risk.
The challenge is that decking condition cannot be confirmed with 100% certainty until the old shingles are removed. Even a thorough attic inspection may miss damage that exists on the top side of the plywood, directly under the shingles. That means a roof may be quoted at price X, then legitimately require additional decking once the roof is opened. At that point, replacement isn’t optional. The roof must be made sound before work can continue.
Where contractors differ is how this is handled.
Some crews replace decking as needed and inform the homeowner of the added expense only after the fact. At Sun Vault Roofing, we take a more transparent approach. We do our best to estimate potential decking replacement in advance, using roof walkability and inspection clues, and include that estimate in your proposal. We also explain upfront that additional decking may be required due to conditions that can’t be fully predicted. If more decking is discovered beyond the estimate, we communicate before costs escalate.
What should I ask my roofer about communication?
Ask your roofer:
Who is my point of contact once work begins?
How will you communicate unexpected findings?
How are change orders approved and documented?
Clear answers protect your budget, your roof, and your peace of mind.
Does My Roof Need to Be Replaced Now or Can It Wait?
Deciding whether to repair or replace your roof isn't always straightforward. Like getting a second opinion from a dentist, you can ask five roofers and get five different answers. And while many contractors strive to be objective, roof replacements are more profitable than repairs, which can subtly bias recommendations of commissioned salespeople.
In most cases, it’s in a homeowner’s best interest to extend the life of a roof as long as it can be done safely. Not every aging roof needs immediate replacement. A knowledgeable, local contractor should be able to tell you whether your roof can make it through another Wisconsin winter and, if so, what short-term repairs or maintenance could reduce risk and buy time.
That said, there are situations where replacement is the responsible option. If a roof has reached the end of its serviceable life, shows widespread failure, or poses a high risk of leaks or structural damage, patching may no longer be viable. When that’s the case, your contractor should clearly explain why, pointing to specific conditions or failure points, not just offering a blanket recommendation. If replacement is the right call, our roof replacement preparation guide walks through what to expect before work begins.
How Long Does a Roof Last in Wisconsin?
Knowing when to repair versus replace depends partly on where your roof is in its lifespan. Understanding roof lifecycle by year helps you evaluate a contractor's recommendation against objective benchmarks, not just their estimate.
How Do I Spot Storm Chasers After a Wisconsin Storm?
After a major storm, out-of-state crews often go door to door offering quick, low-cost repairs and asking you to sign before you have had time to compare. Ask for a local address, proof of insurance and a written estimate, and do not sign anything on the spot. Our post-storm roofing guide covers what to watch for.
How Do Wisconsin Homeowners Spot Roofing and Solar Scams?
Dishonest contractors do not only show up after a storm. Some use high-pressure sales tactics, manufactured urgency or misleading warranty language year-round. Our guide to the most common roofing and solar scams explains how to protect yourself before you sign.
Questions to Ask Your Roofing Contractor: FAQ
What questions should I ask a roofing contractor before signing in Wisconsin?
Ask for proof of current insurance, who owns the company, which manufacturer certification they hold, what the written estimate includes (tear-off, flashing, ventilation, permits), and how long their workmanship warranty lasts. A contractor who answers each of these in writing is worth a second look.
What license should a Wisconsin roofing contractor have?
Wisconsin contractors who work on one- and two-family homes are expected to hold a state Dwelling Contractor credential, which you can look up through the Wisconsin Department of Safety and Professional Services. Also ask for proof of insurance. Permits are handled separately by your city or village, so ask who will pull yours.
Should old shingles be torn off before a new roof is installed?
In almost every case, yes. Roofs installed over old shingles do not last as long, manufacturer warranties are typically invalidated, and the decking underneath cannot be inspected. A trustworthy contractor will explain honestly if an exception applies.
Does a roof replacement need a permit in Madison?
In Madison and many other Wisconsin communities, yes. Your roofer should pull the permit and close out the inspection, because unpermitted work can complicate home sales, insurance claims and warranties.
How long should a roofing workmanship warranty last?
Most contractors limit workmanship coverage to 5–10 years. Sun Vault Roofing's workmanship warranty is 20 years, and it is part of the Sun Vault One Vault Warranty alongside CertainTeed's non-prorated SureStart PLUS 3-Star coverage.
