    I am thinking of putting a sloped roof over a porch.( it has a flat roof now)
    The existing house has a typical old style standard bungalow slope.
    The porch extends 7' 6" from the house.

    I'm trying to work out how far I would need to go back into the house roof to get a good slope. What is the minimum slope I could use.
    The porch will have old style shingle (concrete).

    Any ideas on this please.

    21 degrees aim for with concrete tiles,however this is not a very astecticly pleasing slope for a front porch 30 degrees min if you can get it.tell me the span and i will tell you the rise of this roof if you wish

    Thanks for reply.
    The porch is 9' 6" long and 7'6" deep. ( it extends out from the house 7'6" )

    sorry willie i thought you were putting an apex roof on your porch but from reading this again i think your just coming off your original house with a slope.anyway a guide for you is for every 12 inchs or 300 mm in lenght of roof the rise will be 115 mm so including your soffit when new roof hits exsisting wall of original house it will have reached a height of 920mm and will obviously continue this angle until it reaches original roof.hope this helps
