      Can this product be installed over 5/8" Securock roof sheathing?

      Answer This Question

      Hello Jeff, as long as the sheathing act as a nail base the Tyvek® Roof Protector™ would be able to be installed over it because the Tyvek® Roof Protector™ has to be mechanically fastened to the sheathing.

        Does this product stick to the roof (by preapplied adhesive or something like it) by itself or is it only held on by nails. Obviously it needs nails to finish the job, i was just curiois of its sticky

        Hello - The DuPont™ Tyvek® Roof Protector™ has to be mechanically fastened to the roof sheathing with capped fasteners. There is no adhesive on it and none should be used.

            Can you put this under peel and stick Cap roll shingles
            ByAug 19, 2024
            1 Answer | 
            Answer This Question

            Hello - The lowest recommended slope for use with the Tyvek® Roof Protector is 2:12, in looking at the installation guidelines for peel and stick cap roll shingles, it appears that these should be applied directly to the roof deck, not over an underlayment. We would direct you to the manufacturer of the peel and stick roofing product.

              In two minds whether to use special underlay nail or staples - used for a garage so staples would be fine. Really easy to roll out and staple and nice grip under foot. Good product and no issues.
