When it comes to protecting your home, few things are more important than your roof. Whether you’re facing storm damage, normal wear and tear, or planning a new roof installation, choosing the right roofing contractor is critical, not just for your peace of mind, but for your home’s long-term integrity.
But how do you know who to trust?
In an era where online ads are everywhere and every company claims to be “the best,” it’s more important than ever to do your due diligence. At Clem Davis Company, we’re proud of our legacy, our reputation, and our commitment to helping homeowners in the western Chicago suburbs make informed decisions. We believe that an educated customer is a confident customer. In this guide, we’re sharing the must-know tips for choosing a reputable roofing contractor in Illinois and beyond.
Why Reputation Matters in the Roofing Industry
The roofing industry is one where quality, safety, and reliability must be non-negotiable. Unfortunately, it’s also an industry where “fly-by-night” contractors can cause headaches and costly mistakes.
What Can Go Wrong with the Wrong Roofer?
- Poor workmanship resulting in leaks or structural damage
- Unlicensed contractors who cut corners on materials or safety
- Lack of insurance leaves you liable for damages or injuries
- High-pressure sales tactics with hidden fees or upsells
A reputable roofing contractor helps you avoid all of that. They are licensed, insured, and accountable. They have a long-standing track record, transparent pricing, and numerous positive customer reviews to support their claims.
1. Start with Online Reviews and Ratings
Online reviews are your first line of defense. Sites like Google, Yelp, Facebook, and Angie’s List offer a glimpse into the experiences of other homeowners.
What to Look For:
- High average rating (4.5+ stars)
- Volume of reviews (more reviews = more trust)
- Recent reviews that indicate consistent quality
- Responses from the company, especially to complaints
At Clem Davis Company, we’re proud to maintain a 4.9-star Google rating, backed by decades of service in the Fox Valley, DuPage, and Cook County areas. We believe that our reviews speak for themselves, and we encourage homeowners to read them!
2. Check for Local Licenses and Certifications
Illinois doesn’t require a state roofing license, but local municipalities often do. A trustworthy roofer will have all applicable business licenses and permits, and they’ll be happy to show them to you.
Look for:
- Proof of licensing from your city or county
- Certifications from manufacturers (like GAF, CertainTeed, etc.)
- Membership in professional associations like the BBB or NRCA
Clem Davis Company is a proud member of the Better Business Bureau (BBB) with an A+ rating. We are also a certified GAF Master Roofing Contractor—an elite status awarded to only the top 2% of roofers in North America.
3. Ask About Insurance (and Get Proof)
Roofing is dangerous work. The contractor you hire should carry:
- General liability insurance (to protect your property)
- Workers’ compensation insurance (to protect you from liability)
Always ask for a Certificate of Insurance (COI). If they refuse? That’s a red flag.
4. Evaluate Experience and Longevity
How long has the roofing company been in business? New companies aren’t necessarily bad, but longevity is a strong sign of trust and quality.
“If a roofer has been in business for 20, 30, or 50 years, they’re doing something right.”
Clem Davis Company has been serving the community since 1965. That’s six decades of roofing excellence, right here in your neighborhood. We’re family-owned, community-rooted, and here to stay.
5. Review Their Portfolio and References
A good contractor should be able to show you examples of their work, both through photos and real-life references.
Ask for:
- Before-and-after photos of recent jobs
- References you can call (especially neighbors or people in your zip code)
- A list of project types they specialize in (residential, commercial, etc.)
You can view Clem Davis Company’s portfolio here and see recent jobs in Downers Grove, Naperville, St. Charles, Geneva, Elmhurst, and more.
6. Get a Detailed Written Estimate (Not a Ballpark Number)
Vague or verbal estimates leave room for unexpected fees later. A reputable contractor will provide a written estimate that includes:
- Scope of work
- Materials used
- Timeline
- Payment terms
- Warranty details
Estimates from Clem Davis Company are clear, itemized, and free. No pressure. No hidden costs.
7. Compare Warranties
Roofing warranties come in two forms:
- Manufacturer warranties (on materials)
- Workmanship warranties (on installation)
Look for contractors who back their work with at least a 5–10 year workmanship warranty, along with a strong manufacturer warranty (like GAF’s 50-year limited warranty).
8. Ask About Project Oversight and Crew Training
Not all roofers are created equal. You want a company that trains its crew, follows OSHA safety protocols, and oversees the job from start to finish.
At Clem Davis Company, our crews are professionally trained and GAF-certified. Every project has an experienced foreman on-site to ensure quality and safety every step of the way.
9. Steer Clear of These Red Flags
- Door-to-door roofers after a storm (“storm chasers”)
- Asking for large deposits upfront (more than 20–30%)
- No local address or phone number
- High-pressure sales or “today-only” pricing
If it feels off, it probably is.
10. Support Local, Family-Owned Businesses
Choosing a local contractor means:
- Faster service and better communication
- A team that knows local permit laws and climate issues
- Investing in your own community’s economy
Clem Davis Company has been family-run since day one. We’re your neighbors—and we treat every home like it’s our own.
