Why Contractor Selection Is Critical
A high-quality roofing material installed by an unqualified contractor will underperform and fail prematurely. Conversely, even a standard shingle can last its full rated lifespan when properly installed. Choosing the right contractor is arguably the most important decision in any roofing project — and it's one that many homeowners don't give enough attention.
Where to Start Your Search
Begin by building a shortlist of candidates through reliable sources:
- Personal referrals: Ask neighbors, friends, or family who've had recent roofing work done. First-hand experience is the most trustworthy source.
- Manufacturer installer programs: Major roofing manufacturers (such as GAF, CertainTeed, and Owens Corning) maintain networks of certified contractors who meet training and quality standards.
- Local business associations: Licensed contractors in good standing are often members of regional building or contractor associations.
- Online review platforms: Use these to identify patterns — consistent praise or consistent complaints — rather than focusing on individual reviews.
Essential Questions to Ask Every Contractor
About Licensing and Insurance
- "Are you licensed to perform roofing work in this state/province?"
- "Can you provide proof of general liability insurance and workers' compensation coverage?"
Never hire a contractor who can't provide current certificates of insurance. If a worker is injured on your property without workers' comp coverage, you may be liable.
About the Company and Experience
- "How long has your company been in business under this name?"
- "Do you use your own crew or subcontractors?"
- "Can you provide references from roofing projects completed in the last 12 months?"
About the Project
- "Will you personally inspect the decking once the old roof is removed?"
- "What underlayment and ice/water shield will you use?"
- "How do you handle unexpected decking damage — and what do you charge per sheet?"
- "Who is responsible for pulling the permit, and is it included in the quote?"
- "What is the payment schedule?"
About Warranties
- "What manufacturer's warranty comes with the materials?"
- "Do you offer a separate workmanship warranty, and for how long?"
Red Flags to Watch For
Unfortunately, roofing attracts a higher proportion of fly-by-night operators than many other trades. Be cautious of any contractor who:
- Arrives unsolicited after a storm ("storm chasers") and pressures you to sign immediately
- Requests full payment upfront before any work begins
- Cannot provide a local business address or has only a mobile number
- Asks you to pull the permit yourself — licensed contractors should handle permits
- Provides a quote without inspecting the roof in person
- Offers a price dramatically lower than all other quotes without a clear explanation
- Pressures you to decide immediately or claims the low price is only available today
Understanding the Contract
Before signing anything, ensure the written contract includes:
- Specific materials to be used (manufacturer, product line, color, shingle weight/grade)
- Scope of work in detail (tear-off, decking inspection, underlayment, flashing, cleanup)
- Start and estimated completion date
- Total price and payment schedule
- How change orders (unexpected costs) will be handled and priced
- Warranty terms for both materials and workmanship
Getting Multiple Quotes
Always get a minimum of three quotes for any roofing project. This isn't just about price — it's about comparing how thoroughly each contractor explains the work, how professional their documentation is, and how willing they are to answer your questions. The contractor who takes time to explain every line of the quote is often the one who will take the same care on your roof.
Choosing well at this stage protects your home, your investment, and your peace of mind for decades to come.
