Hi all,
I've got a fibre glass roof on a single story extension. It has a parapet at one end, and originally no gutter on that side. I presume the idea was that the water would run off the parapet, onto the roof, and then into the gutter that runs on the side.
The problem is, water drains off the wrong side of the parapet, and runs down the wall. I put up a bit of guttering (pretty badly), to see if it would fix it, but it doesn't, as there is no overhang, and so it runs behind the gutter.
I can see two obvious fixes:
1/ create a barrier on the top of the parapet, so the water is pushed back onto the roof; or
2/ add an extra layer onto the parapet that sits away from the wall so the gutter can collect the water.
In both cases, I have no idea what materials to use, and how to fix. I thought a lead sheet might work for option two, draped over both sides, but that seems quite expensive. I would just screw some timber to the wall below the fibre glass to provide the "kick" needed to flow the water into the gutter.
Any suggestions (or options 3+??)
