I wanted to thank everyone on this forum that helped to answer a myriad of questions I had as a newbie non-roofer trying to roof a 90-square roof while adding an addition to the house. What makes me a lousy roofer is that it took me 1 year and 2 months to finish it. Of course, it was done in stages - 2 months for the front of house, a long break through winter, then building foundation and framing for the new addition for spring and summer, then another 3 months or so for the back of the house. My ridge vent may not be perfectly straight, my valleys may not be too perfect, but I tried to follow the rules and the house remained dry through a very strong windy rain this week. Hope it continues to stay dry for at least 20 years.
Used OC Duration shingles in Driftwood, OC Deck Defense Underlayment, copper for all the flashing, used Grace IWS for all valleys, eaves, rakes, and roof to wall and roof to chimney transitions despite us getting an average of 1 inch of snow per year. Felt extra cost to materials would make it as watertight as possible. Used all Lifetime Tool branded silicone boot flashing and bathroom venting rated to no leaks up to 120mph einds. Used FAMCO 6 inch kitchen vent, as I felt it was the best option there. Used either Geocel 2300 or Masterseal NP1 caulking for everything, except Henry’s Rubberized Cement for closed cut valley sealing. Followed all your recommendations. Very appreciative of all the patient help I received from everyone. Photos to follow. Happy new year, and happy new roof to us!
An overkill? I hope so!
