Hello! Any advice on roofing conundrum much appreciated…
My roofer was contracted to introduce a rear fall on these newly installed lead dormer tops, to stop rain water falling over the front edge, hitting the window cills/splashing off the bottom of the box gutter (behind the parapet wall in images) and rotting the lower part of the wooden sash window structures/cills.
However, he has now admitted to changing course during the install without communicating with me, saying he added a wooden boss roll each dormer top to allow for lead expansion in hot weather and has put in a forward fall with a front edge drip detail, instead of a rear fall.
He is saying it is not good practice to introduce a rear fall with the boss roll in place. Also he decided because of the age of the roof and slates surrounding the dormers, the front edge drip detail and the dormer roofs falling away from the (already) deteriorating abutment would ensures effective drainage.
Any thoughts on whether I am being given a sound explanation? Also would a gutter on the front of the dormers be a suitable/aesthetically acceptable solution to stopping water cascading over the front of the dormer tops?
Thank you! Rebecca
