This is related to post Why Leaking Roof under Dormer / hole in OSB!!!
.(more pics of valleys/leaks) My home was built in 2003 and roof is 8 years old, yet I have been told the roof is failing. Please see pictures attached: Spidering/cracks everywhere except ridge & top 3 shingle rows. This is a triple wide manufactured home.
What I was told today:
-Roof definitely needs replacing, not just fixed shingling/flashing of dormer valleys. (another roofer thought I have 7-8 years left in the roof)
1) Overexposed shingles..nailing (see pics)
2) lots of vents on roof, but only soffet vent for inflow. Roofer said I need Eave and Ridge venting system, but doesn't know if it can be put in on this home given the 3 sections butt together. The home manufacturer claims their engineering calcs were done and the venting should be sufficient. "All their homes are done this way." (That does not give peace of mind given the other roof issues)
3) potential product issue. This is a Milarkey product
Other issues: Dormers leaking & not properly flashed, valleys done poorly, PVC drip edge not over gutter, no step flashings.
What are your thoughts on 1-3? I don't want to re-roof if venting isn't sufficient.
PS. Please note that 4 of the large rectangular vents cannot be seen from where I am standing. The narrower 2 sections of the home end right above each dormer, and butt to the center section.
