Hi,
I am planning to replace the roof on my garage and was considering adding a lean-to extension onto the back to give me some extra storage space. To maximise the space in the extension (the white structure on the LHS), I'd like to use the rear elevation of the garage as a wall of the extended section.
The issue i'm having is figuring out the valley detail at the apex of the two pitched roofs to get the water to run to the downpipe at the corner of the existing garage. I plan to make the roofs hot roofs with EPDM membrane which I could use a single piece for. However, there's a good chance that water will just pool in the valley without a fall along its length. Is there a better solution to what i'm trying to achieve?
Thanks
