Hi roofers!

I have designed a roof that needs a pitch of 12 degrees. It is for a lean-to extension and with the first floor window and depth of extension, 12 degrees is all i can get. I have attached (i think) a sketch of the detail, and i was wondering if anyone has designed/constructed a roof as low as 12 degrees and whether tye have any comments on the attached sketch detail...

Thanks very much

When you copy & paste the album code you need to use the DIYnot BBCode rather than the external one.

I'll let the roofers comment on the tiles, the Velux & its flashing will struggle in that pitch, Velux’s only go down to 15° unless I’m mistaken.

Thanks, i have been looking more closely at the detail and am going to change it! Raise the pitch to 15 degrees and include a section of flat roof beneath the first floor window. Thanks for your time and trouble though.

Your eaves detail will look horrendous without a soffit overhang. I would suggest you revise this detail.

Zinc, copper or stainless steel standing seam. These can go down to a pitch of 3 degrees so 12 isn't a problem. We have details to help with the installation of velux roof lights as well. Would you be interested in a quote?
