Selecting the right contractor for your roofing project isn’t just about finding someone who can slap shingles on a roof—it’s about trust, materials, installation precision, climate adaptability, and long-term value. At Holthaus Roofing (Canton, IL), these fundamentals meet decades of family-business heritage and certified workmanship. Below we’ll explore what sets a high-quality roofing partner apart, how Holthaus Roofing embodies these traits, and what homeowners and business-owners should evaluate before moving ahead.
Why Contractor Reputation and Certifications Matter
Family-owned history and local roots
Holthaus Roofing is a third-generation business that has served Central and Western Illinois since 1990.That kind of longevity brings more than just years—it brings built-up trust, local climate knowledge, and accountability. Their website states: “Over 30 years of craftsmanship and innovation meet your passion for roofing.”
For you, that means less risk of hiring someone who disappears after a storm or doesn’t stand behind their work.
Industry certifications count
Holthaus holds certifications like the CertainTeed ShingleMaster™ for residential roofing and the Duro‑Last Elite Contractor credential for commercial projects. These are more than nice badges—they reflect training, adherence to installation standards, use of high-quality materials, and access to extended warranties.
When you’re investing in a roof that should last decades, these marks provide peace of mind.
Local licensing and transparency
Holthaus lists its Illinois license number (104.007039) and emphasizes being licensed, bonded and insured. Verifying these credentials protects you. It means the contractor meets state requirements, carries the requisite insurance, and is accountable under local regulations.
One good external reference for homeowners is to check the Illinois Department of Financial and Professional Regulation (IDFPR) database before signing contracts.
What to Look For in Services & Materials
Material choices matched to your property
Homes and commercial buildings in Illinois have to endure summers, snow, ice, hail and wind. Holthaus states that they install asphalt shingles, metal roofs, and even slate for residential properties—and flat or low-slope systems for commercial.
The right material matters: metal and slate often last significantly longer than basic asphalt shingles, though they cost more.
If you’re choosing a contractor, ask: Which materials are best suited to my property’s age, pitch, climate exposure, and budget? Holthaus guides this by tailoring options.
Honest assessment: repair vs replacement
Too often homeowners are pitched an expensive full roof replacement when perhaps a repair would suffice. Holthaus emphasizes their philosophy: “If you don’t need it, we won’t try to sell it…” They provide comprehensive inspections, honest recommendations and long-term planning rather than quick fixes.
For you, that means lower risk of unnecessary overspending—and higher value when investments are warranted.
The process matters
A high-quality contractor follows a transparent process:
- Free inspection and consultation.
- Detailed proposal with materials, timeline and costs.
- Professional installation by certified crews.
- Post-project review and warranty documentation.
Holthaus outlines this process on their website.
Ask your contractor: Will you walk me through options, deliver a detailed written proposal, and provide warranty documentation?
Sustainability and waste-reduction
Yet another differentiator: Holthaus mentions their commitment to responsible practices—recycling old shingles into asphalt pavement, reducing excess waste, and offering energy-efficient roofing options.
If eco-friendliness and long-term efficiency matter to you, this is a meaningful plus.
Why Holthaus Roofing Stands Out
- Deep local experience. Three decades in business means thousands of projects, understanding of local building codes and weather patterns.
- Family-first values. The company emphasizes treating homeowners like “neighbors, not numbers.”
- Certified quality. They hold recognized credentials (ShingleMaster™, Duro-Last Elite) that bring performance and warranty strength.
- Transparent communication. They publish service guides, maintenance tips and project examples, indicating they want informed clients.
- Balanced services. They handle both residential and commercial roofing—so whether you own a home, rental, or business property, their scope is broad.
How to Use This Blog Post — Your Reference Checklist 📋
Whether you’re planning a roof replacement, evaluating a leak or simply gathering information for future care, here’s a checklist to refer to:
- Inspection & Condition Assessment
- Is your roof older than 20-25 years (for asphalt) or showing widespread damage, curling, granule loss? If yes—replacement is likely.
- If minor damage or leaks exist—repair may suffice. Holthaus states they “repair where possible and recommend replacement only when necessary.”
- Ask the contractor for a written condition report and photo documentation.
- Material Fit & Long-Term Value
- Asphalt shingles: cost-effective, good value.
- Metal/Slate: higher upfront cost, but longer lifespan, better for certain homes.
- Commercial flat systems: require proper membrane and proper installation.
- Holthaus outlines these depending on property type.
- Ask: Which material best suits my roof’s pitch, structure, climate exposure, and budget?
- Contractor Credibility & Credentials
- Is the contractor licensed, bonded, insured?
- Do they hold manufacturer-certifications like ShingleMaster™ or Duro-Last Elite?
- Do they provide references, project galleries, maintenance guides?
- Holthaus makes all of the above visible.
- Process & Warranty Transparency
- Get a detailed proposal: scope of work, timeline, materials, clean-up plan.
- Confirm installation standards: who will install, what crew, what safety / clean up process.
- Warranty: materials + labor. Certified contractors often provide better warranties. Holthaus emphasizes manufacturer warranties via their certifications.
- Seasonal Maintenance and Support
- Factor in maintenance: inspections after storms, gutter cleaning, insulation/ventilation check. Holthaus provides guides on this.
- Ask: Does the contractor offer maintenance guidance or follow-up support?
