You might consider something other than standard silicone - black roofing goo probably does better in UV light.ī) consider the porch roof a substrate, not a roof. To reduce the amount of sealant needed consider a foam backing rod (literally to take up space and give the sealant something to hold on to) or a self expanding foam sealant (one can would probably do the trick. If your house roof deck is properly covered with ice shield the roof should be ok, but please beware this possibility!Ī) IF that space between C and B actually vents (where the water is currently going, yes?), then sealing it isn't the worst idea - but you may find the water finds another way to annoy you. Second, you've got a potential ice dam at B so water might back up under the roof A. First, that roof isn't meant to be flat, so water will find its way between seams and around screws and nails. So yeah, if that porch roof is nearly or actually flat then the problems are actually much larger than that one gap. Well, if the water isn't on the roof then the water can't go through the roof, thus keeping the underside dry. This was a roofers slap dash solution to the leak that was even worse before ("fixing" the porch roof was a condition we made for buying the house, and it was done as cheaply as possible it would seem.) They stopped coming back after I bothered them too many times after every heavy rain. I believe that current flashing would work, but the seam ridges keep it suspended when it should actually conform around them. Too much water comes through to be acceptable.

HA, I figured the cardinal rule of roofing would be more like "keep stuff under the roof dry" :) I'd look at your gutters and any trim details on the roof edge.

why isn't the porch roof draining? Unless it is completely flat that water should go away, especially as water coming off the pitched roof has energy to help sweep any water off.

If some water finds its way through a nail hole or something and into that cavity and it can drain away - or vent away - then you can create real problems! The C intersection should be dry, and filling it up with silicone or other sealant violates a cardinal rule of roofing - ALWAYS let the water go.
