Research and Preparation: What Should I Do Before Contacting Roofers?

Before you reach out to any roofing contractor, take time to prepare and do your homework. Start by evaluating your existing roof—look for signs of wear, leaks, or storm damage, and decide whether you need a roof repair or a full roof replacement. Set a realistic budget for your project, keeping in mind the costs of different roofing materials and the scope of work.

Next, research local roofing contractors with strong reputations. Check that they have proper licenses and insurance coverage, including workers compensation insurance, to protect you and their crew. Read online reviews, ask friends and neighbors for recommendations, and consult the Better Business Bureau to identify trustworthy roofing companies. Make a list of questions to ask each contractor, focusing on their experience, the roofing materials they use, and the warranties they offer. A professional roofer will be transparent about their business practices, insurance coverage, and approach to roof installation. Doing this groundwork will help you find the right roofing contractor for your project and ensure a smooth, successful experience.

1. Are You Licensed in This State?

Always confirm that your roofer holds a valid contractor’s license for your state. This ensures they meet minimum standards for training, insurance, and code compliance.

Each Mid-Atlantic state—like New Jersey, Pennsylvania, and Maryland—has different licensing requirements, so ask for their license number and verify it online if possible.

2. Do You Carry General Liability and Workers’ Compensation Insurance?

This is critical. Liability insurance protects your property if damage occurs, while workers’ compensation covers injuries on the job. If a contractor lacks either, you could be held responsible for medical bills or damages.

4. How Long Have You Been in Business?

Roofing is a high-turnover industry. Ask how long the company has operated under its current name, and whether it has a permanent business address. Request a physical address rather than a post office box to verify the company’s legitimacy. Longevity is a good sign of reliability and consistent service.

5. What Types of Roofing Do You Specialize In?

Different roofing materials require different skills. A contractor experienced in asphalt shingle replacement might not be qualified for metal or flat roof systems. Confirm they have specific experience with the material you’re using. When installing shingles, especially new shingles, proper installation techniques are essential to ensure durability and prevent future issues. Make sure your contractor is experienced in installing various roofing materials and follows the shingle manufacturer’s installation guidelines to maintain warranty coverage.

6. Can You Provide Recent References?

A reputable roofer should be able to offer names of past clients—especially in your local area. Ask for 2–3 references and follow up with a few questions about the quality, cleanup, and communication throughout the project. Specifically, request to speak with past customers who have had their roof replaced in the last few years to better understand the roofer’s workmanship and long-term results.

7. Will You Provide a Detailed Written Estimate?

Verbal quotes aren’t enough. Request a written estimate that includes a detailed cost breakdown for labor, materials, timeline, and cleanup. This prevents surprise charges and ensures everyone agrees on the scope.

8. What Warranties Do You Offer?

Roofing warranties typically include:

Manufacturer warranties for materials (usually 25+ years), provided by the shingle manufacturer. To maintain this warranty, proper installation by an authorized or qualified contractor is required.
Workmanship warranty from the contractor, which covers potential installation errors and varies by company.

As an Owens Corning Platinum Contractor, Dream Home Roofers offers extended system warranties few others can match.

9. How Will You Protect My Property?

Ask how the crew will protect your landscaping, windows, siding, driveway, and yard during the project. Roofing debris can cause damage if not carefully managed with tarps, catch systems, or protective boards.

10. What Is Your Process for Cleanup?

Confirm that cleanup includes nail sweeping, debris hauling, and checking gutters for leftover materials. Ask your contractor how many nails are used per shingle and ensure that all nails are thoroughly removed from the yard after the project. A clean jobsite reflects professionalism and prevents hazards.

11. How Will You Handle Weather Delays?

Mid-Atlantic inclement weather can change quickly. A quality roofer will have a plan for securing the work area and rescheduling as needed, including contingency plans for unexpected inclement weather, to ensure safety and maintain workmanship standards.

12. Who Will Supervise the Job?

Clarify who your point of contact will be during the project. Is there an on-site foreman? Will the person who sells the job also oversee the crew?

Clear communication avoids misunderstandings.

Project Management: How Will You Communicate Progress and Handle Issues?

Clear communication is key to a successful roofing job. When evaluating roofing contractors, ask how they plan to keep you updated throughout your roof repair or replacement project. A reputable roofing contractor should outline how often you’ll receive progress reports, who your main point of contact will be, and how quickly they respond to questions or concerns.

Find out how they handle unexpected issues, such as weather delays or changes in the project scope. Ask about their process for tracking the project’s schedule, budget, and quality of work, and how they document any adjustments. The right contractor will have experience managing similar jobs and a proven system for resolving problems efficiently. By understanding their project management approach, you can feel confident that your roofing job will stay on track and meet your expectations from start to finish.

Subcontractors and Crews: Who Will Actually Be Working on My Roof?

It’s important to know exactly who will be working on your house during a roof replacement or repair. Ask your roofing contractor whether they use their own in-house crews or hire subcontractors for the job. If subcontractors are involved, inquire about their qualifications, experience with your chosen roofing materials, and familiarity with local building codes.

A reputable roofing company should have strict standards for hiring and supervising all workers, ensuring they are trained in safety protocols and proper installation techniques. Ask about background checks, drug testing, and ongoing safety training for everyone on your property. Understanding who will be on your roof—and how they’re managed—gives you peace of mind that your project will be completed safely, professionally, and in compliance with all building codes.

13. What Is the Payment Schedule?

Avoid contractors who demand full payment upfront. A typical schedule includes a deposit, milestone payments, and a final payment upon completion and inspection. Be sure to clarify the payment terms with your contractor, including the accepted payment methods, the payment schedule, and any conditions tied to each payment. Ask how payment is handled—use traceable payment methods like checks or bank transfers, and avoid cash payments or other risky practices.

14. Do You Pull the Necessary Permits?

Roof replacements usually require local permits. Before starting any roofing work, always ask if a building permit is required for your specific project. Obtaining a building permit is necessary for most roofing work to comply with local codes and avoid fines. Your contractor should know what’s needed in your city or township—and handle the process for you.

15. How Will You Ensure the Job Is Done Right?

The final steps of your roof replacement or repair are just as important as the installation itself. Ask your roofing contractor about their process for final inspection and project completion. A professional roofer should have a detailed checklist to verify that all work meets their standards and complies with local building codes.

Find out how they handle any remaining punch list items, warranty claims, or touch-ups before you sign off on the job. Ask about their cleanup procedures, including debris removal and protecting your landscaping and property. A reputable roofing company will only consider the project complete when you are fully satisfied with the results. By understanding their final inspection process, you can be confident that your new roof is built to last and your property is left in excellent condition.

16. What Is Your Repair Policy After Installation?

Even quality roofs can experience minor issues after installation. Ask what happens if something goes wrong in the first year—like a small leak or loose flashing. It’s important to have your contractor inspect any repairs, especially around critical areas such as flashing and the chimney, to ensure proper protection and prevent future problems.

FAQs

Is it okay to get multiple roofing quotes? Yes. Comparing 2–3 quotes helps you understand average costs and verify professionalism.

How do I know if a roofer is insured? Ask for proof of liability and workers’ comp insurance. A reputable contractor won’t hesitate to share documentation.

What does “Platinum Preferred” mean? It’s the highest level of certification offered by Owens Corning, indicating top-tier workmanship and warranty eligibility.

Can I stay home during roof work? Yes, though it may be noisy. Contractors should communicate timing and safety precautions.

How long does a roof replacement take? Most asphalt shingle replacements take 1–3 days depending on the size and weather conditions.

How important is ventilation in roofing? Proper ventilation is crucial for maintaining attic health and preventing moisture buildup. Features like ridge vents help improve airflow, reduce the risk of mold, and prevent issues such as ice dams by allowing heat and moisture to escape from the attic.

What should I know about skylights during a roof replacement? Skylights require careful handling and professional installation to prevent leaks. Proper flashing and sealing around skylights are essential to avoid water intrusion and future complications.

What is a roof deck and why does it matter? The roof deck is the structural base beneath your shingles. Protecting the roof deck during installation is important because water that seeps past shingles can damage it, leading to costly repairs.

How do ice dams form and how can they be prevented? Ice dams form when heat escapes into the attic, melting snow on the roof, which then refreezes at the eaves. Proper ventilation and drainage systems help prevent ice dams by keeping the roof temperature consistent and allowing water to flow off the roof.

Why is professional installation important for roofing? A professional install ensures all roofing components, including shingles, skylights, and ventilation systems, are properly fitted. This helps prevent leaks, protects the roof deck, and extends the life of your roof.
