About a month ago I had a contractor replace a roof that got damaged from a storm but when they had the shingles off another storm blew through overnight and blew the tarp off and a lot of water got in the house.

I redid the roof… it’s multicolored… used up shingles I had laying around… but still a new roof.Trying to decide if I should sell it.

Find a reputable roofing company-look at online reviews and find one that has been in business for a while...ideally local company.Inspect the roof-are shingles curling?

City had already approved a shear wall to ceiling but inspector dictated it go to shingles.  

Inspectors will check for leaks, sagging, or missing shingles, particularly in older homes.
