How to choose a roofing contractor in Columbus (from people who are one)

A mid-grade shingle installed well will outlast a premium one installed badly, which makes picking the contractor the highest-leverage decision in the whole project. It is also the one nobody teaches you to make until the week you need to. We are a roofing company, so read this as a guide from inside the industry: what the paperwork should look like, which warning signs are reliable, and the standards we expect you to hold us to.

Paper first: the certificates worth asking for

Licensed, bonded and insured appears on every truck door in central Ohio, and as a phrase it costs nothing. Certificates cost something, so ask for them. Ohio handles most residential contractor licensing at the local level, so confirm the company is registered in your jurisdiction and carries the bond your city requires. Then ask for a certificate of general liability insurance and proof of workers’ compensation coverage, sent directly from the contractor’s insurance agent, since a certificate that arrives from the agency cannot be an expired photocopy.

Roofing is dangerous work performed on your property, and if someone is hurt on your roof while the coverage turns out not to be real, the question of who pays can land uncomfortably close to your own homeowner’s policy. No contractor with real coverage is offended by the request; hesitation here is an answer in itself.

What a real written scope looks like

A real scope reads like a build plan, not a promise: line items for tear-off, underlayment, ice and water shield with coverage stated, drip edge, new flashing (reusing old flashing under new shingles is a leak on a timer), ventilation, cleanup, and the magnet sweep. Materials should be named by manufacturer and product line, because architectural shingles is a category, not a specification. Read the decking clause closely, since nobody can see through shingles to the wood below: the honest version names the cost of replacement wood in advance and commits to documenting any change in writing, with photos, before work continues.

Warranties come in two kinds, and both belong in writing. The manufacturer warranty covers the shingle itself, where defects are genuinely rare; the workmanship warranty covers the installation, where most early roof failures actually start. A 50-year manufacturer warranty paired with a one-year workmanship warranty protects you against the least likely failure and leaves you exposed to the most likely one. Read what voids them.

Red flags that should end the conversation

An offer to eat or rebate your insurance deductible should end the meeting: Ohio law does not allow contractors to absorb deductibles, so a contractor offering it is volunteering to start the relationship outside the law. Pushing an overlay is a quieter shortcut. Nailing new shingles over old hides the condition of the decking, voids most manufacturer warranties, and cooks the new roof from below: cheaper on day one, more expensive every day after.

After a storm, add three more. A door-knocker pushing an assignment-of-benefits form on day one is asking for control of your claim before your insurer has seen the roof; reputable crews document first and let you decide with your adjuster. A large cash deposit demanded up front is the setup behind most abandoned-job stories, while a modest, refundable deposit to reserve a crew date is normal. And a price quoted from the driveway is not a price, because nobody can count facets, judge decking, or spec ventilation from the ground.

Good signs that rarely lie

The most reliable green flags are habits of documentation: a contractor who documents everything is planning to be accountable for everything. On a repair, the diagnosis should start from the attic side, tracing moisture to the actual entry point instead of caulking whatever looks suspicious from a ladder. On a replacement, expect photos of the decking after tear-off, the layers before they are covered, and the finished flashing, because photos of what got covered up are the only proof most of the job will ever have.

The same discipline shows in how change is handled. Hidden decking damage, the one legitimate mid-job surprise, should arrive as a written change order with photos, at terms already in your contract, signed before work continues. On insurance work, items the first estimate missed get filed as written supplements with your insurer, not quietly left out of your roof to make the number work.

Hold us to every line of this

Ace Roofing is a new name in Columbus, and we know how that reads at the end of a guide about vetting contractors. It is a new name, not a new crew (our crews are led by chiefs with years on central Ohio roofs), but do not take that on faith either. Ask us for the certificates, the 25-year workmanship warranty, and the 50-year registered, non-prorated system warranty option that transfers once if you sell. Our contracts name decking repair at material cost, documented with photos before work continues, and reserving a crew date takes a fully refundable $500 deposit, not a third of the job in cash.

If a full replacement is on the horizon, the vetting can start from your couch. Book online and three fully specified options, with materials named, scope itemized line by line, and both warranties in writing, arrive by email in minutes with a complete measurement report of your roof, free. That estimate is for full replacements only (repairs, storm damage, and gutters get a free on-site assessment), and the button reads "Get my estimate in minutes." Check any bid on your table against this guide; we wrote it expecting to be measured by it.
