    Going from pitched roof to flat


    I have a bungalow which has a small extension to the side running the length of the property. The flat roof on the extension is knackered. I want to take it all off and re-do the extension properly by building and replacing all the windows etc. Where the original house was the guttering is still on it and the flat roof is under the guttering. When i build the side extension do i need to keep this guttering or can i raise the roof a little and have it so the rain water runs straight off the house roof onto the flat roof then into the gutter of the flat roof? If not what else coudl i do?

    "Yes that's the best thing in my opinion to do. Pitch the roof and install guttering around it. Seal the roof with a lead flashing where it meets the house and the pitch will let the water travel down into guttering."

    "You are very correct in the idea of the flat roof being raised and the original roof tiles sitting on the flat roof so that the rain water runs straight onto the flat roof and into its guttering. This is common on lots of extensions."
