I have damp patches in the sloping ceiling either side of the dormer window in an attic bedroom.
I have enlisted help/advice from two local, well recommended roofing companies but the advice
differs -
1. Remove some tiles and investigate - "it's probably the flashing around the dormer" or
2. Remove some tiles and remove the orange/yellow fibre glass insulation sandwiched between the internal
plaster board and the roof felt. The same insulation as used above the attic ceilings.
The glass fibre is subject to condensation.
It is complicated by the fact that both contractors know the estate quite well and have pointed out
that the Marley tiles used by the developer went out of production soon after the estate was built
in early 2000s. Hence both say that they can't match the tiles, so a complete re-tiling of that side of
the house will be necessary.
If it is cause #2, then an alternative and less costly solution might be to remove the offending fibre
glass from the inside by taking down the plaster board. Then replacing with such as Celotex from the inside
between the rafters. A relatively more simple job for a local builder rather than a roofer
In case someone has similar - the house was built by Barratt in 2003 and they call it a "Salisbury".
Thoughts/advice, please.
