So to update everyone, the new roof installation is in progress and no issues seen so far.
What did we find out about the first bad installation?
#1 #30 felt did not have enough caps installed. This was causing the bulged shingles and wavy roof.
#2 Sheathing was not nailed down properly after first tear off.
#3 Chimney flashing was installed incorrectly.
For the new shingles that have been installed, no issues with bulging or wavy roof. Yay!!
What I don’t understand about the first installation, good starter shingles were used. Drip edge was good quality, Even the felt was good quality. Why would the contractor or roofer try to go cheap on the shingles and hired labor? He could have prevented future legal issues and this could have been a good outcome and good review for quality work. What a waste.
