You ask how is the overall install going:
Since I am going to a metal roof and do not believe in build-ups (job is only as good as its foundation) and knowing I have some water damage along the eaves the job was to replace any bad areas. This was allowed for at the tune of $43/sheet installed, knowing that the cost of 5/8 CDX is less than $20/sheet.
The replaced sheathing consisted of using a double layer of 1/4 inch, where at least one of the patch areas has a hole the size of my fist next to it!!
During the tear off one section of eave trough was damaged.
Specification called for Titanium UDL-50 underlayment and I&W to be used. Titanium UDL-30 was used and investigation into the Carlisle CCW WIP 100 I&W shows that it should not be used under a metal roof.
And to top things off at this point there is not one piece of the metal roofing system on the site (due in Wednesday).
So based on the above, how do you think the install is going?
My focus is not to nail the guys b**** to the wall, but to determine a viable method to correct the the I&W issue and at the same time provide a long lasting (compatible with the roofing system warranty) I&W shield for the home, without having to worry about it melting and running or leaching.
To accomplish this if it takes new sheathing then so be it. If it can be scraped back without destroying the existing sheathing that is OK too. If it can be gone over with another product that will preclude the identified issues and maintain warranty, then that may be a way to go, noting that going over other products void most warranties.
Again, I’m just looking for a best viable resolution (what to do) for an incorrect/incompatible I&W being laid down.
