What documentation should a homeowner ask for from a roofing contractor?
Short Answer
Homeowners should ask for: proof of insurance (certificate of insurance showing general liability and workers' compensation), proof of licensing or registration (NJHIC registration number for New Jersey), manufacturer certification documentation, a detailed written estimate with specific products and scope, warranty documents (both manufacturer and workmanship), and references. A contractor who provides all of this documentation is demonstrating transparency and professionalism.
Detailed Explanation
Before hiring a roofing or exterior contractor, homeowners should request and verify several key documents. Certificate of insurance — this is a document from the contractor's insurance company (not just a verbal assurance) showing general liability and workers' compensation coverage with adequate limits and current dates. Without proper insurance, the homeowner could be liable for injuries or damage during the project. Proof of licensing or registration — in New Jersey, home improvement contractors must register with the Division of Consumer Affairs and display their NJHIC registration number. Verify the registration through the state website. Manufacturer certification documentation — if the contractor claims manufacturer certifications (like Owens Corning Platinum Preferred), ask for documentation and verify with the manufacturer. The manufacturer's website typically has a contractor locator that lists certified contractors. Detailed written estimate — the estimate should specify the products (manufacturer, product line, model), scope of work (tear-off, underlayment, flashing, ventilation, decking), what is included and excluded, pricing, and payment terms. Warranty documents — both the manufacturer's warranty and the contractor's workmanship warranty should be provided in writing before the project. References — ask for references from recent projects and contact them. A contractor who readily provides all of this documentation is demonstrating the kind of transparency that distinguishes professional contractors from less reliable ones. A contractor who is reluctant to provide documentation may have something to hide.
Why It Matters
Documentation is the evidence that a contractor is qualified, insured, and transparent. A contractor who cannot or will not provide documentation is a significant risk.
