We were looking help water run-off in a valley where multiple roof lines meet.
The roofers just finished the job yesterday, but it seems like it should be smooth.
Here was the information on the bid for this project.
Remove shingles from flat roof between the garage and house
install a 1/2" fiberboard over the flat roof deck
Install a rubber membrane fully adhered to the fiberboard
Re-shingle the area surrounding the flat roof with OC black shingles
Thanks in advance for any advice.
