Eternabond Tape on Roof Length-Wise Seam
My Cougar EDPM roof is in good shape with no leaks.
To help keep it that way I am planning on getting some 6" Eternabond tape for some preventative medicine.
Putting it across the front and rear cap seams is straightforward enough - just center it over the middle of the transition seam between the cap and roof.
But two questions after that:
Should the tape that I apply on the length-wise run of the trailer butt up against the edge moulding on the roof side and then have that "hairline" seam area sealed with some Dicor?
Or should the tape, in a somewhat similar fashion like on the front and end cap, overlap the side roof edge moulding but only by an inch or so - so that the seam crests the top of it and the outer edge is actually just slightly on the downward direction - i.e. gravity will pull the water away from the edge of the tape/moulding?
I think the second method by eliminating the horizontal seam between the moulding and the roof will off the best protection.
The answer to this question will determine whether I go with a 6" wide run of tape here too or can save a little $ yet still have plenty of coverage with 4" wide tape.
Second question is where the long side ride of tape meets the front/rear width cap tape should they overlap or be cut so that they butt (and be sealed with a little Dicor)against each other.
This question can also apply to any square application like around vents etc - butt joints and seal or overlap and a small dab on the inside and outside edge where they meet.
I am guessing the butt joints would offer a cleaner looking result?
