Hello, I had a freind install a new roof about 3 years ago, removed the cedar shake, put down plywood, tar paper etc. It has always leaked. He knows now one mistake he made was at the “channels” (since I dont’ know the proper term) where two different angles come toghether. They are supposed to be interweaved I guess and were not.
Ihave had two roofing contractors come out this week to inspect and estimate for repair. Both have told me almost exact same thing, so I guess its true. Just wanted a little more verification, info if I may, from any experts out there.
They both said in addition to the interweaving that a huge mistake he made was over exposed the shingles. The both said 5-5/8" is the max it should be and he has 6" and more. Because I used sort of cheap compostion roofing, the guy yesterday told me without question that this will start to cause major problems in x amount of years, maybe as few as 2 or 3 more.
It appears I need to re-roof. The channels could be fixed, but if this overexposed is a major a screwup as they both seemed to think, that would be throwing good money after bad if I repaired the interweaving. Do you guys concur that this over exposed is very serious and will cause big time problems in x amount of years. I plan to live here the rest of my life, and even if I wanted to sell, the guy yesterday told me the roof would never pass inspection, though they don’t always go up there and inspect the roof.
Weather might be pertinent to advice, I live in Fairfield, CA, halfway between SF and Sacramento, lots of rain in winter, sometimes blistering heat in summer. July August alwasy bring some 100 degree and more, but otherwise often in the 80s and 90s. Winter 30s or 40s overnight, maybe 50s to 60s in daytime. And some very signifciant rain from Dec thru March.
Anyway, I guess the crux is, due to this over exposed, is refoofing the best way to go, or is it overkill? THanks for any info and light you can shed on this.
