Damp on bedroom ceiling.

[mark1a]

There is damp on my ceiling,I've had a quick look outside and noticed that roughly where damp is the felt torn and is now hanging down. That has happened in several places. What are my opinions? If. Needed I'll get photos in daylight.

When the council was putting new roofs on my neighbours house they said mine needed doing cos the felt was old. They quoted at the time like £7k

Cheers

mark1a, good evening.

Images please??

Is it possible the work undertaken by the Council has in some way occasioned your felt to deteriorate?

Do you know how old the felt on your roof is? and what sort of area is involved?

Ken.

Thanks ken . We bought the house 2 years ago and I don't think there was any mention in the report. I doubt what the council did has anything to do with it. Also no idea how old the felt is.

I'll post pics Tomo if it's light enough when I get in.

please post pics of damp signs - the outside of the roof - the underside of the roof in the loft?

I'll post pics when I get in of the outside and inside. I'll have to wait for someone else to go in to loft for me as I can't get up there myself.

Image 1 is where damp is

Image 2 just cracked felt
Image 3 is how half is
Image 4 and 5 is how some are but no signs of damp.

The damp

My partner in her wisdom just decided to paint the bedroom a year ago in her hope of making it look good. I don't think there was damp then but she never took the peeling paint off either

 

[bobasd]

thanks for the pics.
but they dont get me much further.
pics of the roof surface would help?
the felt appears to be a modern type?
such tears in the felt at the eaves bays should have been well visual to any surveyor?

maybe, some roofer will ladder up, and remove tiles/slates from the bottom course of tiles above the bedroom damp signs.
this would enable them to examine the conditions near the eaves/gutter area.

ask for photos of their findings, and ask them to go in the loft.

Looks like condensation to me!
op the roof covering keeps the water out not the felt.
Ventilation and insulation in loft should be your first port of call.

Bob, cheers I'll try for a roof pic asap. 'll try find the report and see what it says

Thanks. The loft has insulation and I know there is ventilation as when I been on the ladder at the hatch I can see outside.

As for condensation I tend to leave 2 windows open in day for good 5 hours. The windows have no air vents

 

[Alastairreid]

If the insulation is not covering that edge of the ceiling it will create a cold spot and that is the result you would get.

What you have is a classic symptom of cold bridging i.e. condensation related mould. Its no surprise either that it is occurring at one of the most vulnerable places on a building. Think about it - the point at which the roof rafter joins the ceiling rafter at the eaves, happens to be the shortest distance to the outside and least protected.
