Do you want to know one of the MOST common roofing problems that causes damp?
Do you have a tiled pitched roof with a felt underlay fitted before 2000?
Do you have signs of damp on walls close to the roof?
Then chances are your felt underlay has rotted away near to the gutter, allowing water to pass into the cavity, causing damp walls!
This common problem can be fixed without the need to re-felt the whole of your roof.
See below how this problem can be resolved:

The lower section of tiles are removed, with the felt underlay cut away

A plastic tray is then fitted to the base of the rafters, which overhangs into the gutter

A new lower section of felt underlay is then fitted

New tile batten is fitted
