I’m having a flat roof replaced on a single garage and a couple of roofers have had a look at it. Both have suggested a 3 layer felt.
One has suggested that the felt across the fall of the roof with overlapping felt. To a layman this suggested that water would never seep through these joins.
The other suggested that the felt should always run along the direction of the fall with overlaps as it stops water sitting behind each over lap ( when felt is run across).
Can someone pleas advise. Thanks in advance.
