Materials
Are both bids using the same shingles, underlayment, starter, ridge cap, fasteners, and accessories?
The Same Roof Test
Before You Compare Roof Bids, Make Sure You’re Comparing the Same Roof.
A cheaper bid may not be cheaper if it leaves out the work, materials, protections, or accountability that make the roof last.
The Same Roof Test helps homeowners compare roofing bids by scope, not just the final number.

Before comparing price
The Lowest Bid Is Not Always Bidding the Same Job.
Two roofing bids can look similar on price and still describe very different jobs.
One bid may include proper flashing, ventilation, tear-off, cleanup, warranty, and crew standards. Another may leave important details vague, excluded, or hidden until later.
That is why good roofers should not be judged only against the lowest number.
If two bids do not include the same work, they are not really competing bids.

Are These Really the Same Roof?
Use this free tool to compare two roofing bids by scope, materials, warranty, cleanup, and accountability — not just the final price.
You do not need to upload private customer documents. You can paste only the scope language or answer the checklist manually. Do not paste sensitive personal information unless you are comfortable doing so.
The checklist
The Same Roof Test
Before choosing the lowest roofing bid, compare these items side by side. The test is simple: before comparing price, compare what’s included.
Tear-Off
Does the bid include removing old roofing, or is it layering over existing problems?
Decking
How is damaged or rotten decking handled, priced, and approved?
Flashing
Does the bid clearly include proper flashing around walls, chimneys, valleys, skylights, and penetrations?
Ventilation
Does the roofer address attic ventilation, intake, exhaust, and manufacturer requirements?
Permits and Code
Does the bid include required permits, code compliance, and local inspection requirements where applicable?
Labor and Crew Standards
Who is doing the work, and what standards are they expected to follow?
Cleanup
Does the bid include debris removal, magnetic nail cleanup, and protection of landscaping, gutters, driveways, and property?
Warranty
What is covered, who stands behind it, and what happens if something leaks later?
Accountability
Is there a real company, real contact, real documentation, and real follow-through after the job?

A Simple Reply Good Roofers Can Send
Use this when a homeowner says they got a cheaper bid or asks you to match a number that may not include the same roof.
For homeowners
Ask Better Questions Before Choosing the Lowest Bid.
A good roofing contractor should be willing to explain what is included. A responsible homeowner should be willing to compare more than price. The goal is not to overpay. The goal is to understand what each bid actually covers before deciding who to trust with the roof over your home.
What exactly is included in this bid?
What is excluded?
What materials are being used?
How are flashing and ventilation handled?
What warranty is included?
Who handles cleanup?
What happens if there is a leak after the job?
Are permits, code requirements, and inspections included if
required?
Why Roofers Chamber created this
Incomplete Bids Should Not Win by Being Vague.
Roofers Chamber exists to support working roofers, raise standards, and help homeowners recognize contractors who do the job the right way.
The Same Roof Test is one small example of that mission: make it easier for good roofers to explain value clearly and harder for incomplete bids to win on price alone.
Roofers first. The trade stronger.
After you show homeowners how the scope compares, make sure your company is clear and trusted online.
The Roofer AI Visibility Gap Checkup helps roofing companies see whether search engines, maps, directories, homeowners, and AI systems can understand their services, proof, warranty, reviews, project evidence, and local trust signals.
Questions
Clear Answers for Bid Comparisons.
Is the cheapest roofing bid always bad?
No. A lower bid can be legitimate. The point is to compare what is included before deciding that one bid is truly cheaper.
Why do roofing bids vary so much?
Bids can vary because of materials, tear-off, flashing, ventilation, labor standards, warranty, cleanup, permits, and how unexpected issues are handled.
What should a homeowner ask before choosing a roofer?
Ask what is included, what is excluded, what materials are used, how flashing and ventilation are handled, what warranty applies, and who is accountable after the job.
How can roofers use this page?
Roofers can send this page to homeowners who are comparing bids only by price. It helps reframe the conversation around scope, standards, and accountability.
