Porch roof, metal roof (old school flat sheet metal)
Hi all, hoping for some ideas regarding how to approach an issue. I have a house built in 1920. It had a "newer" porch built around 1970-ish. The roof arch is very similar to that in the image, as is the trim wood along the sides of the roof. A lot of the wood under the edges of the roof started rotting out pretty badly last year so I have re-engineered it with pressure treated 2x8 (the weight of the roof was previously resting on a 1x8 box "frame"). Its solid as hell now, but the rotting is largely due to the fact that the metal roof edge (this is old school flat sheet metal on arched rafters, they bent the edges over onto themselves for extra rigidity/support I presume) AT the very edge of the roof metal is angled slightly upward. This is causing the rain to roll over the edge and under the 1 inch overhang and in some spots apparently finding its way between the metal roof and the wood it is resting on, to the inside the actual wooden structure. I am looking for suggestions on something other than taking a mallet and beating the edge into a downward slope. I will be putting gutters into french drains on both sides after I get the correct angle on these edges. What do ya got?
