Most homeowners call a roofer when something is already wrong. A storm rips shingles, a slow leak stains the ceiling, or a real estate inspection flags soft decking. The clock starts ticking, estimates arrive, and the temptation is to pick the lowest number and hope for the best. In my experience, the difference between a roof that performs for 25 years and one that fails in six often comes down to what the homeowner asked before they signed.

Roofing looks simple from the ground. Up close, it is a chain of decisions about materials, ventilation, fastening patterns, flashing details, safety, scheduling, and warranty coverage. Good decisions add durability and value. Bad decisions add risk that tends to show up when the first hard rain or heavy freeze hits. The way to get those decisions right is to ask clear, pointed questions and listen for confident, specific answers. Here is how to do that.

Start with the basics: licensing, insurance, and who actually does the work

Ask for their state or local license number and verify it yourself. Regulations vary by state and municipality; in many places, legitimate roofing contractors need either a state contractor’s license, a specialty roofing license, or both. I have seen bids from “companies” that share a PO Box and a cell phone, but no license history. That is a red flag. A real roofing company can tell you exactly which board licenses them and whether any complaints or suspensions exist.

Next, ask for a certificate of insurance, issued directly from the agent, naming you and your property as the certificate holder. Two coverages matter: general liability, typically at least $1 million per occurrence, and workers’ compensation. If a worker falls or a ladder takes out a window, you do not want to learn you are the deep pocket. Policies lapse. Require proof that is specific to your address and call the agent to confirm it is active through the timeline of your job.

Clarify who will be on your roof. Some reputable roofing companies maintain in‑house crews; others rely on subcontractors. There is nothing inherently wrong with subs, but control and accountability change. If subs will do the roof installation, ask for the subcontractor’s legal name, proof of insurance, and who supervises them. A professional roofer can tell you the crew lead’s name, how long they have worked together, and how communication flows from you to the superintendent to the crew.

Scope and diagnosis: make sure the contractor has looked under the hood

Estimates built solely on a satellite takeoff or a quick drive‑by are risky. A careful roofing contractor will inspect the attic when possible, check for signs of deck deflection, moisture staining, mold, rusted nails, and inadequate ventilation. They will measure intake and exhaust, note bath fan terminations, and look at chimney mortar and counterflashing. When I walk a roof, I bring a moisture meter, a camera, and a flashlight. I want to know what is happening under the shingles, not only on top.

Ask the roofer what they found and invite them to show you photos. Encourage plain language. If they think sections of decking are compromised, ask how they will confirm that before change orders escalate the price. Some companies include a per‑sheet price for decking replacement in the contract. Others include an allowance. Neither is wrong, but you want a realistic plan. If your home was built before the mid‑1990s, ask whether plank sheathing rather than plywood is present. Some shingle manufacturers require specific decking thickness and smoothness to honor a warranty.

Materials and system components: more than just shingles

Roofs fail at the seams and edges first. That is where materials and craftsmanship make their living. Shingles are the visible piece, but a roof system also includes underlayment, ice and water barrier, drip edge, starter strip, ridge cap shingles, flashing metals, pipe boots, and ventilation.

Ask which shingle brands and lines they recommend and why. A blanket claim like “Architectural shingles last 30 years” tells me the salesperson is parroting a brochure. Good contractors will reference the exact product line and warranty type. For example, they might propose a mid‑grade laminated shingle with a limited lifetime warranty and an upgraded algae‑resistant blend if your home sits under heavy tree cover. If you live near the coast or in a hail zone, the conversation should include impact‑rated shingles, thicker gauge metal, or a different fastening schedule.

Underlayment choices matter too. Traditional felt, often called 15‑pound or 30‑pound, still appears on bids because it is inexpensive. Synthetic underlayment is lighter and more tear‑resistant under foot traffic and wind. In valleys and along eaves, a self‑adhering ice and water barrier helps prevent leaks from wind‑driven rain or ice dams. If your winters see consistent freeze‑thaw, push for a generous application of that membrane at the eaves, around penetrations, and in valleys.

At the edges, drip edge flashing should run along eaves and rakes, with the correct overhang and color that matches or complements the fascia. Starter strips, not cut shingles, belong under the first course to ensure shingle adhesion. Around chimneys, skylights, and walls, step and counterflashing should be replaced, not caulked and prayed over. I have torn off too many “new” roofs that failed because the crew reused crumbly flashing or smeared mastic as a shortcut.

Ventilation deserves its own check. Balanced intake and exhaust help keep the deck cool, reduce condensation, and extend shingle life. Ask for the net free vent area calculation based on your attic square footage. If the plan includes a ridge vent, confirm continuous soffit intake exists. If your home lacks soffit vents, a ridge vent by itself creates negative pressure and can pull conditioned air and moisture from the house, which backfires. Gable vents paired with ridge vents can short‑circuit airflow; a thoughtful roofer will explain the trade‑offs and propose a coherent design.

Fasteners, patterns, and wind ratings: small details with big consequences

Every manufacturer publishes nailing patterns and zones on the shingle wrapper. Ask where the nails go and how many per shingle the crew uses. Four nails are common in lower wind areas. Six nails per shingle, driving through the nail line, not above it, increases wind resistance. Nails should be corrosion‑resistant and long enough to penetrate the deck by at least 3/4 inch or fully through the sheathing. Overdriven or underdriven nails, or nails placed high above the glue strip, are leading causes of blow‑offs and leaks.

In high‑wind regions, the contractor should reference specific approvals like ASTM D3161 Class F or ASTM D7158 Class H ratings and local code requirements. If your home carries a steep slope or a complex cut‑up roof with multiple hips and valleys, ask how they adapt patterns to those details and how they stage materials to avoid scuffing in heat.

Tear‑off versus overlay: why starting fresh usually wins

An overlay, laying new shingles over old, can save money and limit mess. It also buries existing problems and leaves the deck uninspected. I rarely recommend overlays unless budget or structural constraints force the issue and the existing layer is flat, well bonded, and recent. Most manufacturers limit warranties on overlays, and many building codes allow a maximum of two layers, beyond which a tear‑off is required. A proper roof replacement includes full tear‑off, removal of all nails, inspection and re‑nailing of deck sheets, and deck repairs as needed.

If a roofer pushes an overlay without documenting why your deck and current system justify it, be cautious. If you do accept an overlay, ask how they will treat flashings and penetrations, and how they will handle ventilation and added weight.

Skylights, chimneys, and penetrations: plan for the tricky bits

Roofs do not leak in the middle of a field of shingles; they leak at terminations. Chimneys should receive new step and counterflashing tucked into a reglet cut into the mortar joint, not just surface‑mounted and sealed. Ask whether the contractor will grind new joints or reuse old counterflashing. Skylights older than 15 years often fail shortly after a new roof goes on because seals and cladding age differently from fresh shingles. Many roofers recommend replacing older skylights during roof replacement because the labor to reflash is similar. If you keep existing skylights, demand new flashing kits from the skylight manufacturer.

Plumbing vent boots come in different materials. Cheap neoprene boots crack under UV in a few years. Upgraded silicone boots or lead flashings last longer. Ask which they use. For bath fans and dryer vents, verify that ducts terminate through a proper roof vent with backdraft damper, not into the attic. Satellite mounts and solar attachments need coordination with your roofer and the provider, with proper flashing kits rather than sealants.

Scheduling, weather strategy, and site protection

Good roofers watch the forecast, but weather shifts. Ask how they stage a roof installation so your home is never exposed overnight. I like to see roofs torn off and dried in the same day, with underlayment and ice barrier in place before calling it. On larger roofs, crews should sequence sections so only what can be protected is open. Ask whether they use harnesses and anchors, and how they protect landscaping and AC units with plywood and tarps. Dumpsters should have driveway protection. Nails do not belong in your lawn. A magnetic sweep at the end of each day is standard, and a final sweep at project closeout catches stragglers.

Noise and debris are part of roof repair and roof replacement. A respectful roofing company will explain daily start and stop times, restroom arrangements, and where materials will be staged. If you work from home or have pets, plan accordingly. If your attic houses valuables, cover them. Tear‑off dust finds its way through light fixtures and gaps.

Permits, code compliance, and inspections

Ask who pulls the permit and which code cycle your municipality enforces. The answer matters. Code dictates valley types in some places, ice barrier lengths, ventilation minimums, and re‑nailing of sheathing in high‑wind zones. Your roofer should be conversant with those rules and schedule required inspections. If a contractor asks you to pull an owner‑builder permit so they can sidestep licensing or insurance obligations, walk away. Pass or fail reports are public record in many jurisdictions. A qualified roofer welcomes an extra set of eyes.

Warranty terms and what they actually cover

There are two layers of warranty to understand: manufacturer and workmanship. Manufacturer warranties on shingles often read “limited lifetime,” but the non‑prorated period in which they cover full replacement is shorter, commonly 10 to 15 years, then coverage prorates. Many manufacturers offer enhanced warranties when an authorized roofing contractor installs a full system of branded components and registers the job within a set time. Ask whether your roofer is certified with the brand, which level of program applies, and what documentation you will receive. Enhanced warranties may extend non‑prorated periods and include disposal and labor in case of a manufacturing defect.

Workmanship warranties come from the roofing company and cover errors in installation. I see terms from one year to ten years, sometimes longer for commercial roofs. The length is less important than the history and reputation behind it. A 10‑year promise from a contractor who formed an LLC last month is weaker than a 5‑year promise from a firm with three decades of local presence. Ask for references from jobs at least three years old and request addresses you can drive by. If they balk, consider why.

Clarify what voids the warranty. Foot traffic from other trades, storm damage, unvented attics, and unapproved modifications can nullify coverage. If you plan to add solar later, ask how the roofer coordinates flashing attachments and maintains warranty coverage. Some companies offer solar‑ready flashing locations or return to flash mounts for a fee.

Estimates, allowances, and change orders: money without surprises

An estimate should read like a recipe, not a riddle. Look for line items that name each component: shingle brand and line, underlayment type, ice and water barrier location and length, drip edge gauge and color, starter strips, ridge vent model, flashing scope, number and brand of pipe boots, skylight work, chimney work, ventilation changes, and decking contingencies. If a roofer writes “replace as needed,” that line needs a unit price and a not‑to‑exceed figure. Exact numbers protect both parties.

Payment schedules tell you a lot. Reasonable terms often include a modest deposit to secure materials, a progress payment when materials arrive or mid‑project, and a final payment upon completion and your sign‑off. If a roofer asks for the full job cost up front, reconsider. If you are using insurance proceeds, request that the roofing company work with your adjuster on supplements for code upgrades or hidden damage. A competent contractor can speak the language of Xactimate and provide photo evidence.

Ask how they handle unexpected structural issues. If the crew opens the roof and finds rotten rafters, who authorizes the fix, and at what rate? Change orders should be written, priced, and approved before work proceeds. Verbal agreements evaporate when the dumpster leaves your driveway.

Comparing bids: apples to apples without guesswork

Homeowners often receive three estimates and discover a frustrating spread. The cheapest looks appealing until you realize one bid includes only two rows of ice barrier, no ridge vent, reused flashing, and four nails per shingle, while another includes full tear‑off, six‑nail pattern, upgraded underlayment, and all new flashing metals. Create a simple comparison sheet that lists the key components and checkmarks what each roofer includes. The lowest price sometimes hides the future cost of callbacks and water stains.

Anecdotally, I have watched two neighboring homes roofed the same week. The lower bid reused the old step flashing and dabbed sealant where new shingles met the chimney. The higher bid ground in new counterflashing and lapped fresh step flashing with appropriate overlaps. The first home called me after the first nor’easter with a wet hearth. The fix cost more than the difference in bids.

Ask for proof of craft: photos, references, and crew standards

A strong roofer carries a portfolio. Ask to see before‑and‑after shots of similar roofs, especially those with features like dormers, multiple valleys, or complex flashing. Better yet, ask for two addresses you can drive past. A tidy site is a tell. Look for straight courses, aligned ridge caps, neat terminations at walls, and metalwork that looks intentional, not pieced. Reviews are useful, but direct conversations with past clients reveal how the contractor communicated when something went sideways. Every project has a hiccup; you want the roofer who owns it and fixes it.

Ask what training the crew receives. Manufacturers and trade associations offer certification courses. Crew leads who can explain why a closed‑cut valley was chosen over a woven valley for your shingle type and climate have invested in their craft. If your roofer shrugs and says “we have been doing it this way for 20 years,” that might be experience speaking, or it might be complacency.

Safety culture and your liability

Roofing is dangerous work. A company that takes safety seriously reduces accidents and delays. Ask whether they use personal fall arrest systems, roof anchors, guardrails on low slopes, and ladder stabilizers. Confirm they comply with OSHA standards and conduct toolbox talks. If the answer is vague, it often shows in rushed setups and avoidable mishaps. I have seen a crew skip anchors, then spend half a day chasing sliding shingles and dropped tools. Safety discipline increases productivity and quality.

Special cases: metal, low‑slope, and historic homes

Not all roofs are asphalt shingles. If you are considering standing seam metal, ask about panel gauge, substrate, clip spacing, and the difference between snap‑lock and mechanical seam systems. Coatings, thermal movement, and oil canning need attention. For low‑slope sections, materials like modified bitumen, TPO, or PVC might be appropriate. Shingles on a low slope below the manufacturer’s minimum pitch are a leak invitation. A seasoned roofing contractor will recommend the right system for each plane rather than forcing one product everywhere.

Historic homes introduce unique constraints. Plank decking may require overlay with plywood for a smooth nailing surface. Original trim profiles and copper flashing details deserve preservation. If your home is in a historic district, the roofing company should be familiar with approval processes and acceptable materials. Replacing cedar shakes with asphalt may require board review. Copper, zinc, and slate work demand specialized tools and skills. If your roofer has never soldered a copper pan or staged slate ladders, do not let them learn on your house.

Storm claims and the traveling crew problem

After hail or wind events, out‑of‑area roofing contractors flood neighborhoods Roofing company with clipped flyers and quick sign‑ups. Some do good work, many do not. The sales cycle is fast, the production is faster, and warranties can vanish with the license plates. If you choose to work with a storm‑response company, vet them twice as hard. Ask where their office is, how long they have operated under the current name, who services warranty claims months later, and whether local references exist. If they insist you sign a contingency agreement on your porch before an estimate, slow down. Insurance work often requires supplements; a capable local roofer can navigate that without high‑pressure tactics.

Communication and project management: who answers the phone

The best roofing company you will ever hire returns calls, sends updates, and tells you when plans change. Ask who your point of contact is from contract to final inspection. On larger crews, a site superintendent or foreman manages day to day. I like to see a pre‑start meeting that confirms material colors, access routes, power sources for compressors, and special concerns like garden ponds or toddler nap times. During the job, a daily recap with photos gives peace of mind. At the end, a walk‑through with a punch list makes sure small details like paint touch‑ups on vent stacks or gutter cleaning after tear‑off happen.

Maintenance, small repairs, and life after the check clears

A new roof is not a set‑and‑forget system. Ask your roofer what basic maintenance they recommend: clearing leaves from valleys, checking sealants around penetrations annually, and keeping gutters clean. Some roofing contractors offer inexpensive annual inspections. If a branch scuffs shingles or a minor leak appears, a contractor who values long‑term relationships will send a technician for a reasonable service call rather than selling you an unnecessary replacement. If the company only takes on full roof replacement and leaves small roof repair calls to voicemail, remember that when comparing bids.

A short, practical checklist for your conversations with roofers

Can you provide your current license number and a certificate of insurance listing me as certificate holder?
Who will install my roof, your in‑house crew or subcontractors, and who supervises them day to day?
What did you find during your attic and roof inspection, and can you show me photos?
Which exact materials are you proposing for shingles, underlayment, ice barrier, flashing, and ventilation, and why?
What are your workmanship warranty terms, and how do you handle unexpected decking or structural repairs?

Red flags that deserve a second look

A bid that is dramatically lower than others with vague line items like “flashing as needed.”
Pressure to sign on the spot or to pull the permit yourself.
Reluctance to replace flashing at chimneys, skylights, or walls.
No attic inspection, no ventilation discussion, or no photos from the evaluation.
Requests for full payment before work begins.

When the answers reveal the right partner

What you are listening for in all these questions is not just content, but posture. A trustworthy roofer welcomes hard questions and speaks in specifics. They know their craft, they respect your money, and they do not hide their process. They bring up trade‑offs unprompted, like when six nails are worth the time, when a ridge vent is wrong for your house, or when a skylight should be replaced instead of reflashed. They keep tidy edges in their work and in their paperwork.

I have walked homeowners through options that cost less than they expected when we improved ventilation rather than upsizing shingles, and I have recommended spending more where it mattered, such as full tear‑off and new flashing on a chimney that had leaked for years. The goal is not to win the job at any cost. The goal is to install a roof system that does not surprise you later.

Roof installation is one of the larger checks many people write for their home. With the right questions, you turn that check into a long, quiet span of seasons where the roof simply works. A careful selection now, based on clear answers from a qualified roofing contractor, saves time, money, and drywall down the road. And when weather rolls in and you hear the first drumming drops, you will be glad you took the time to ask.
