Roofing discussions and local services.
hypothetical scenario: your roofer skips the underlayment step - what would you do?
Discussion options
Okay, so imagine this... you're getting your roof redone, and you specifically chose CertainTeed's Integrity Roof System because you heard good things. But then, um, you notice the roofer is skipping the underlayment step entirely, saying it's not really necessary in your climate. I mean, I'm no roofing expert, but that sounds kinda sketchy to me. Would you trust their judgment or insist they follow the manufacturer's guidelines exactly? Curious how others would handle this.

A contractor should be able to point to the exact CertainTeed installation document and section supporting any claim that underlayment is unnecessary, especially when the job is being sold as an Integrity Roof System. Any deviation should be documented in writing.
There are two separate checks:
- Whether local code requires underlayment or a particular type of secondary water-shedding protection.
- Whether omitting it affects CertainTeed system requirements or warranty eligibility.
Even if shingles can physically be installed without underlayment in some circumstances, that does not necessarily mean the complete Integrity Roof System is being installed as specified. For readers planning a similar project, the contract should identify the underlayment product, installation method, and who accepts responsibility for an omission.
