Start with scope and experience
Ask what types of roofs a contractor installs most often and how long they have worked locally. A company that does mostly shingles may not be the right fit for slate or flat roofing.
Ask about underlayment, flashing, ventilation and decking in plain terms. Clear answers show real knowledge.
Request examples of similar projects and descriptions of how each was done.
Prepare a short description of your roof and goals before calling. Include the age of the roof, any leaks and what you want to change. Good contractors appreciate clear information and respond with clear questions.
Check status and requirements
Rules about who may perform certain work and what must be registered are set by the state and local officials. Ask each company about the requirements for your project and verify them with official sources.
A resource such as the state regulatory boards portal can help you check.
Do not rely on words alone. Verify with the source.
When you check a company, look at more than one source. Official portals, local government offices and written documents all tell part of the story. A company that shares information openly is easier to trust with a job.
Compare written proposals
A good proposal lists roof size, materials, underlayment, flashing, ventilation, decking terms, permits, cleanup, start and finish estimates and payment steps.
Be wary of proposals that are one line long or vague about decking and ventilation.
Put proposals side by side and compare scope before price.
Read each proposal slowly. Highlight items that appear in one bid but not another. Then ask each contractor about the differences instead of guessing. The answers often reveal how carefully the proposal was prepared.
After a storm
Storms bring out many roofers. Take your time, get more than one opinion and be cautious about anyone who pressures you to sign immediately or offers to waive your deductible.
Your insurer decides coverage. A contractor can document damage but should not promise a claim result.
Ask for photos and a written scope.
If a roofer arrives unannounced after a storm, take their card and say you will call back. A reliable company will understand and will still be there next week with a written scope.
Red flags
Pressure to sign quickly, large upfront payments without a clear reason, no local office, reluctance to put things in writing and promises that sound too good to be true are signs to slow down.
A roof that looks inexpensive but leaves out layers can cost more in the end.
Trust your instincts and take time to check.
Take payment terms seriously. Payments tied to progress and clearly described stages are easier to follow than large upfront amounts. Ask about the schedule of payments before you sign anything.
Making the decision
Choose the contractor who understands your roof, explains the plan clearly and gives a complete written scope. Price matters, but so do details and communication.
Keep copies of the proposal, product information and any approvals.
Our bid comparison tool can help you score proposals on your priorities.
Before deciding, picture the whole project with each contractor. Who will you call, who will be on site, how will cleanup be handled and what happens after? Choose the one who gives you the clearest, calmest picture.
Hire the contractor who explains underlayment, flashing and ventilation clearly, shows a local track record and puts a complete scope in writing.
