Choosing a roofer should involve more than collecting three prices. The owner is comparing business legitimacy, technical scope, project management and accountability.
Verify the Contractor Through Washington L&I
Washington L&I maintains a public Verify tool. Use it to review the contractor's active registration and available public records. What the number itself means — and what it does and does not prove — is explained in the Contractors Glossary entry on contractor registration numbers.
Make Sure You Are Comparing the Same Scope
One estimate may include full tear-off, new flashing and detailed decking terms while another assumes overlay or excludes key items. Compare line by line. Our roofing cost guide explains how to compare roofing estimates.
Ask Roofing-Specific Questions
- What roof system are you proposing and why?
- What happens if damaged decking is found?
- Which flashing is replaced?
- How are penetrations handled?
- How is the building kept watertight during work?
- Who handles permits if required?
- What is excluded?
- What written workmanship warranty is provided?
- Which manufacturer warranty applies, if any?
Be Careful With Unsupported Claims
Do not rely on “best,” “#1,” “certified,” “lifetime,” “licensed,” or similar marketing language unless the underlying claim is verifiable and accurately described.
Read the Contract
The contract should identify the legal business, project address, scope, materials, price, payment structure, change-order process, responsibilities, exclusions and warranty terms.
Before signing, make sure the paperwork terms are clear. The independent Washington construction reference Contractors Glossary explains in plain language what a scope of work, a change order, an allowance and retainage mean on a Washington project.
Use the Roof Condition to Drive the Decision
A reputable recommendation should explain why repair, restoration or replacement fits the observed condition. Learn more about A1 Roofing.
