Low single pitch extension roof questions
I will shortly be rebuilding a small extension on the back of my house (its currently so badly built that it looks like it will fall down before too
long!! )
Its currently a single pitch lean-to construction, built "over the top of" the existing (typical ex-council house) reinforced concrete
roofed outhouse.
I am looking to rebuild the extended bit, leaving the outhouse as is, then dry line the outhouse as its not cavity walled, and incorporate some s/h
double glazed windows into the structure.
Question is, how to do the roof. At the moment its a felted roof (just crap shed felt) and has wood panelling to make up the small gables.
I quite like the idea of felt as its cheap. I am redoing the joists so can support whatever weight but tiles are pricey and its probably on the edge
of suitability in terms of pitch angle.
If I were to marine ply the roof and then use "torch-on" felt, how do I then do the gable edges, is it just a case of torching the felt
around onto the soffit board? I don't think this will look very good, but I can't think of a neat way to finish it off.
I am also stuck with a very small sliver of brickwork for the gable, sat on a lintel over a big wide window, so its almost not worth having the
brickwork there (again, at the moment its tongue and groove wood panelled).......any ideas folks.??
Any suggestions gratefully accepted!
cheers

I'm just in the process of tiling and roofing my new 6 x 3 M brick extension.
All the joists and tiles only cost me £300 max and it will last a lot longer than felt.
Hard work though!
Sorry, not very helpful was it.
The house next door has a flat roof and there felt is just wrapped around the edges and tucked up under the slight overhang.

i think you build the roof too big and tuck under, ie 90 degrees down, then 100 degrees round and under so its pointing back up, to stop drips running
round. Then put the guttering under this to catch what runs off.  Diydoctor might help.

well I dunno!!
Where did you get the tiles from?
No roof of that size will be much less than £300 so I may yet go for tiles! Let me know your sources!
