The Homeowner’s Cheat Sheet: 10 Questions to Ask During Your Roofing Estimate

ByBenjamin Compas

A roofing estimate shouldn’t be a one-way sales pitch; it should be an interview. You aren’t just buying shingles; you are hiring a protector for your home’s most valuable asset.

Many homeowners in the Treasure Valley make the mistake of looking only at the bottom number. However, a “cheap” estimate often hides expensive shortcuts that you won’t notice until the first heavy Boise snow. This guide provides ten specific questions that will reveal a contractor’s true colors and ensure you get a roof built to last 30 years, not 3.

The Legal & Logistics Questions

1. Are you registered and insured in Idaho?

In Idaho, every contractor must be registered with the State Contractors Board. Ask for their RCE number and verify it online. If they aren’t registered or don’t carry General Liability and Workers’ Comp, you could be held liable for any accidents on your property.

2. Who actually does the work—employees or subcontractors?

This is a critical distinction. Many large companies “farm out” their labor to third-party subcontractors. At Emerald Roofing Group, we take pride in using our own trained crews. This ensures a higher level of quality control, better communication, and absolute accountability for every nail driven into your roof.

3. How will you protect my property and landscaping?

Roofing is messy. A total tear-off involves thousands of pounds of debris. Ask if they use specialized systems like the “Catch-All” mesh to protect your shrubs or plywood to shield your windows and AC units. A pro leaves your yard looking better than they found it.

The Technical & Material Questions

4. Will you remove the old roof entirely?

Avoid the “layover” trap. Shingling over old layers might save 20% upfront, but it traps heat (which “cooks” your new shingles) and prevents the contractor from seeing rotted wood underneath. Always insist on a full tear-off down to the decking.

5. What specific brand and tier of materials are you using?

Not all “30-year shingles” are equal. Ask about the underlayment. Are they using old-fashioned felt paper that tears easily, or a modern synthetic underlayment that offers superior moisture protection?

6. How are you handling the “weak points” like flashing and vents?

Dishonest roofers save $200 by reusing your old, rusty flashing. A quality estimate should include new, custom-fitted metal for your chimney, valleys, and vents to prevent the most common causes of leaks.

The Climate-Specific Questions

7. How will this roof handle Idaho’s specific weather?

The Treasure Valley is a wind-tunnel. Ask about the wind rating of the shingles and whether they use a 6-nail fastening pattern for extra security.

8. What is your ventilation plan?

In Boise’s 100°F summers, an unventilated attic can reach 150°F, destroying your shingles from the inside out. Ask your estimator to explain the balance between intake (soffit vents) and exhaust (ridge vents) for your specific attic space.

The Warranty & Financial Questions

9. What is the difference between your material and workmanship warranties?

The manufacturer (like GAF) covers a defective shingle, but the contractor covers the leak. Ask how long their labor guarantee lasts. A “Lifetime Material Warranty” is useless if the roofer who installed it won’t come back to fix a leak two years later.

10. How do you handle “unforeseen” costs?

What happens if they find rotted plywood (decking) once the shingles are off? A transparent company like Emerald Roofing Group will have a pre-set, itemized price per sheet of plywood in the contract, so there are no surprises on your final bill.
