roof adhesives ????

I just spent many thousands of dollars to have my house completely reroofed. I found out the roofer is using Liquid Nails-heavy duty, to seal all the flashings,to cover the exposed nails,to seal the shingles and any other place where a sealant is needed. I have never heard of using this.Has any one else? Is it OK? Will it void my warranty?
I really need to know. Please HELP I live in so AZ.

I have used these forums,and have always come away with answers.

Exposed nails? Sealing shingles? Sealing flashing? With some form of glue?

Sounds like you hired somebody pretending to be a roofer. I doubt there'll be any warranty that can be of any use.

You could be OK - it would be helpful if you could upload pictures of suspect areas to a file sharing service and link to them here.

Where an adhesive is required (for example to adhere shingles on steep-slope roofs or at valleys) shingle manufactures typicality specify "Asphalt Roofing Cement meeting ASTM D4586".

The roofer may be using Liquid Nails RR-808 Roof Reapir, which is a sealant, this could be acceptable (for example) to cover exposed fasteners at the end ridge cap shingle, though most roofers prefer "Asphalt Roofing Cement" in such applications as they feel it is more durable.

Generally, best practices for flashing installations do not make extensive use of sealants, however I would not condemn such use wholesale but instead look are each specific application, for example the NRCA Steep Slope Roofing Manual illustrates the use of counter flashing (for example, at a chimney) in an installation that includes the correct use of sealant:

Where roofers get into trouble is when they attempt to use adhesives and sealants as a substitute for correct installation techniques, for example if the roofer is using "Liquid Nails Construction Adhesive" where the manufacturer is specifying "Asphalt Roofing Cement", then you have problems.
