8 Questions to Ask Your Roof Installer Before Signing a Contract

Updated: Aug 3
Replacing your roof is one of the biggest investments you'll make in your home. While price is important, choosing the right roofing contractor is about much more than finding the lowest bid. Asking the right questions can help you avoid costly surprises, poor workmanship, and future leaks.
Before signing any roofing contract, here are eight questions every homeowner should ask.

1. Are You Licensed and Fully Insured?
This should always be your first question.
A reputable roofing contractor should carry the appropriate licensing (where required) along with both general liability and workers' compensation insurance.
Why it matters:
Protects you if an accident occurs on your property
Ensures the contractor meets state requirements
Demonstrates professionalism and accountability
Don't be afraid to ask for proof of insurance. A trustworthy contractor will gladly provide it.
2. What Manufacturer Warranty Does My Roof Qualify For?
Many homeowners assume all new roofs come with the same warranty—but that's far from the truth.
Manufacturer warranties vary depending on:
The shingles selected
Whether a complete roofing system is installed
The accessories used
Installation methods
Some contractors install only enough products to qualify for a basic limited warranty, while others install complete manufacturer-approved roofing systems that qualify for enhanced warranties with longer coverage and stronger protection.
Ask exactly what warranty you'll receive—and why.
3. What Will You Replace Besides the Shingles?
Your roof is much more than shingles.
A quality roof replacement should address critical components such as:
Pipe boots
Furnace (B-vent) flashing
Roof jacks
Chimney flashing
Step flashing
Wall flashing
Drip edge
Ridge ventilation
Some contractors reuse aging flashing to reduce costs. While it may save money upfront, worn flashing is one of the leading causes of roof leaks after replacement.
Your proposal should clearly identify what will be replaced and what, if anything, will be reused.
4. How Will You Protect My Property During Construction?
Roof replacements can generate thousands of pounds of debris.
Ask how the contractor plans to protect:
Landscaping
Flower beds
Driveways
Pools
Air conditioning equipment
Windows
Outdoor furniture
Also ask about cleanup procedures, including magnetic nail sweeps and final inspections.
A professional contractor should leave your property looking as good as—or better than—they found it.
5. Will You Inspect My Roof Deck?
The shingles only perform as well as the decking beneath them.
During tear-off, damaged or rotted wood may be uncovered that wasn't visible during the initial inspection.
Ask:
Is decking replacement included?
How are damaged areas documented?
What are the replacement costs if repairs are needed?
A contractor who plans ahead for these possibilities is less likely to surprise you later.
6. How Will You Ensure Proper Ventilation?
Proper attic ventilation plays a major role in:
Roof lifespan
Energy efficiency
Moisture control
Shingle performance
Poor ventilation can contribute to excessive attic temperatures, trapped moisture, mold growth, and premature shingle deterioration.
Your contractor should evaluate both intake and exhaust ventilation—not simply replace what's already there.
7. Who Will Actually Be Installing My Roof?
Not every roofing company installs roofs the same way.
Ask questions such as:
Are the installers employees or subcontractors?
Who supervises the project?
Will there be a dedicated project manager?
How many years of roofing experience does the crew have?
A quality installation is just as important as quality materials.
8. Can You Provide Local References and Recent Projects?
One of the best indicators of future performance is past work.
Ask for:
Recent local projects
Customer references
Online reviews
Before-and-after photos
A reputable roofing contractor should have no problem showing examples of completed work in your area.
Local experience also means the contractor understands regional weather conditions, building codes, permit requirements, and roofing systems that perform best in your climate.
Bonus Question: What Isn't Included in the Estimate?
This may be the most important question of all.
Instead of only asking what's included, ask:
"What isn't included?"
This often reveals differences between competing estimates.
Items commonly omitted from low-cost proposals include:
Pipe boot replacement
B-vent flashing
Chimney flashing
Drip edge
Ventilation upgrades
Ice and water barrier
Manufacturer-approved accessories
Enhanced manufacturer warranties
Decking allowances
Cleanup and disposal
Knowing what's excluded helps you compare estimates fairly instead of simply comparing prices.
Choosing the Right Roofing Contractor
The best roofing contractor isn't always the cheapest—but they should always be transparent.
A detailed estimate, quality materials, proper installation practices, strong warranties, and clear communication provide far more value than simply choosing the lowest price.
When comparing roofing proposals, focus on the complete roofing system, not just the total cost. The right contractor will take the time to answer your questions, explain their recommendations, and help you make an informed decision without pressure.

Discuss property protection measures and payment policies to avoid surprises.
