Roofing is one of the few trades where the quality of the work is almost impossible for the customer to inspect. It's thirty feet up, it gets covered over as it goes, and problems surface years later. That gap is exactly why choosing the contractor matters more than choosing the shingle.
Verify the boring things first
Ohio does not license roofing contractors at the state level, which means the burden of checking falls on you. Some municipalities require local registration; most don't. So start with insurance, because that's where homeowners get genuinely exposed.
- General liability insurance. If a contractor damages your home — and roofing work does sometimes damage gutters, siding or landscaping — this is what covers it.
- Workers' compensation. This is the big one. If an uninsured worker is injured on your roof, you can end up personally liable. Roofing has one of the highest injury rates of any trade.
- Certificates, direct from the insurer. Ask for a certificate of insurance sent from the insurance company, not a photocopy from the contractor. It takes one phone call and it's the single most protective thing you can do.
Local matters more than it sounds like it should
A contractor with a real address in Warren County has something at stake. They'll still be here when your warranty needs honouring, their reputation circulates by word of mouth locally, and they know how southwest Ohio weather actually behaves — the freeze-thaw cycles, the hail season, how ice dams form on the eaves here.
Ask how long they've worked in this specific area and for addresses of jobs nearby. Driving past a few completed roofs tells you more than any brochure.
Read the reviews properly
Star ratings on their own don't say much. What's useful is the pattern underneath.
Look for reviews that mention the things that go wrong: how the contractor handled a delay, a surprise, a warranty claim, a bit of damage. Any roofer can look good on a job that went smoothly. How they behave when something goes sideways is the actual signal.
Check whether the company responds to criticism, and how. A defensive or dismissive reply to a negative review tells you what you'd be dealing with.
Warranties come in two kinds, and people confuse them
The manufacturer's warranty covers the shingles themselves against defects. It's issued by the shingle maker and it's generally reliable — but it typically covers materials only, and it can be voided by improper installation or inadequate ventilation.
The workmanship warranty covers the contractor's installation. This is the one that actually matters, because the overwhelming majority of roof failures come from installation error rather than defective shingles. Ask how long it runs and get it in writing.
A workmanship warranty is only as good as the company standing behind it, which loops back to why local and long-established matters.
Red flags worth walking away from
- Storm chasers. Crews that appear door-to-door after a hailstorm, often from out of state. They'll be gone before any warranty issue surfaces.
- Large deposits up front. A reasonable deposit is normal. Being asked for most of the job before materials arrive is not.
- Pressure to sign today. Any legitimate quote holds long enough for you to think. "This price is only good if you sign now" is a sales tactic, not a business reality.
- Offering to cover your deductible. This is insurance fraud in Ohio. A contractor willing to commit fraud with your insurer is telling you something about how they'll treat you.
- No written contract, or a vague one. The scope, materials, timeline, payment schedule and warranty all belong in writing before work starts.
- Cash-only, no paper trail. Walk away.
The questions worth asking every bidder
Ask all of them the same list, and compare the answers rather than the totals:
- Are you insured for both liability and workers' comp, and can your insurer send me the certificate?
- Do you use your own crews or subcontractors? If subs, are they insured?
- Is tear-off included, or are you laying over the existing roof?
- What happens if you find rotted decking, and what's the per-sheet rate?
- What ventilation work is included?
- How long is the workmanship warranty?
- Who is on site supervising day to day?
- How do you handle cleanup, particularly nails in the yard?
Vague answers to specific questions are information.
How we work
Mastercraft Restorations is based in Lebanon and has been working on roofs across Warren County for over thirty years. The owner is on site for our projects rather than a crew manager you've never met, most replacements are finished in one to two days, and we handle insurance documentation as a matter of course.
We also tell people when they don't need a roof. If yours has five good years left, that's what our inspection will say — even though it means we don't get the job.
Call (513) 446-8017 or use the form on this page for a free inspection, and we'll come back to you within one business day.
