I am having a re-roof job performed in a couple of weeks.
1.does outside temperature matter at time of install?
2.installing a ridge vent-Trimline brand
are their different ridge vent models? should I know which model roofer intends to install? is one mdl better than another? should I even care?
3.the ridge vent will have the shingle over shingle…
do I need special shingles installed over the ridge vent? shingle chosen is GAF/Elk Prestique HD 30 yr. do I automatically assume that builder will install the correct one?
4.Is it cost effective to consider upgrading to the 40 yr Prestique HD?
5.I have a Fl room on back of house that has two “valleys” on the roof. these valleys have the shingles woven together. I notice on brochures and other homes that some have a copper type valley. what is the advantage if any over one type vs the other? Each valley is about 10-12 ft from the top to the gutter. of course these valleys catch the rain from the Fl room.
your advice is appreciated.
