10 Essential Questions to Ask Before Signing a Roofing Estimate
It is the most common mistake homeowners make: scrolling straight to the bottom of a quote to find the smallest number. In the roofing world, however, the “cheapest” price often becomes the most expensive repair five years down the road.
A roofing estimate shouldn’t just be a price tag; it should be an interview. You are hiring a protector for your home’s most vital asset. In the Treasure Valley, where our roofs must survive 100°F summer bakes and heavy winter snow loads, the how of the installation is just as important as the how much. This guide provides the ten questions you must ask to ensure you’re hiring a local Idaho craftsman, not just a salesman.
The “Must-Have” Legal & Safety Questions
1. What is your physical address and Idaho RCE number?
A P.O. Box is a major red flag for “storm chasers” who disappear once the clouds clear. In Idaho, any contractor performing work over $2,000 must be registered. Ask for their RCE number and verify it; this ensures they are a legitimate business entity held to state standards.
2. Can you provide a current Certificate of Insurance (COI)?
You need to see two types: General Liability (which protects your home and property) and Workers’ Comp. If a worker is injured on your roof and the contractor doesn’t have Workers’ Comp, the financial liability could fall on you, the homeowner.
3. Will you pull the local building permits?
If a roofer asks you to pull the permit as the “owner-builder,” walk away. This is often a tactic used by unlicensed contractors to avoid a final inspection. A professional handles the paperwork and ensures the City of Boise or Nampa signs off on the safety of the work.
The Technical Installation Questions
4. Are you removing the old roof entirely?
Avoid “layovers” at all costs. Shingling over old layers traps heat—effectively “cooking” your new shingles and voids most manufacturer warranties. A full tear-off is the only way to inspect the structural integrity of your home.
5. What is your plan for the “hidden” components (Decking and Underlayment)?
Ask specifically how much they charge per sheet if they find rotted wood (decking) after the tear-off. In 2026, expect a transparent rate of $45–$75 per sheet. Also, ensure they are using modern synthetic underlayment rather than old-school felt paper, which tears easily and lacks the moisture resistance needed for Idaho winters.
6. Will you replace the flashing and drip edge, or “reuse” them?
This is where cheap quotes save money. Reusing old, rusty flashing is the #1 cause of leaks in new roofs. A quality estimate includes new metal for chimneys, valleys, and edges.
7. How are you addressing attic ventilation?
Most roofs fail from the inside out. Ask your contractor to explain how they will balance intake and exhaust airflow so your attic doesn’t turn into an oven in July.
Property Protection & Logistics
8. How will you protect my landscaping and driveway?
Roofing is a destructive process. Ask if they use specialized “Catch-All” systems or heavy-duty tarps to protect your expensive Boise landscaping and windows from falling debris and thousands of nails.
9. Who is my point of contact on-site?
Will there be a dedicated supervisor present, or is the job being handed off to a crew of subcontractors you’ve never met? At Emerald Roofing Group, we believe in direct accountability, you’ll always know who is in charge of your home.
10. What is the cleanup process?
Ask about the “Magnetic Sweep.” A pro doesn’t just pick up the big pieces; they run high-powered magnets over your lawn and driveway to ensure your family (and your tires) stay safe from stray nails.
Warranty & Future-Proofing: The Double Guarantee
When discussing warranties, remember the “Double Guarantee.” The Manufacturer Warranty covers the shingles if they fail, but the Workmanship Warranty covers the installation if it leaks.
Ask if the warranty is transferable. If you decide to sell your Meridian or Nampa home in a few years, a transferable warranty is a massive selling point that adds real value to your home. At Emerald Roofing Group, our warranty isn’t just a piece of paper; it’s a promise from a neighbor who will still be here next season.
