wet insulation

[Ethel]

my loft insulation is wet as the breathable membrane the roofer left uncovered for two days let rain in. Should it be replaced or will it dry out.

Advice please Is this material waterproof? Ridge tiles cant be put on as too cold. Could rain come through.

I think the 1/2 hour express advice service is down due to the weather.

The 24 hour service may still be running though

They've not been able to get to the computers as a snow drift has formed on entrance to the room & the gritters haven't been out. They may be even later

The felt should be replaced if wet, and the membrane is waterproof so why did it get wet in the first place?

 

[datarebal]

generally the breathable membrane is water resistant some better than others.
if the roof is tiled then the ridge not bedded should not cause a problem.

The insulation should be replaced.

The OP should be replaced.

The roofer said it gets wet when it touches something and they put tiles on in rain. Thanks guys for your replies.

The roofer said it gets wet when it touches something .

He may have a point there If this wonder sheet all singing breathable membrane is like a canvas tent - then if you touch the inside the water will come through where touched - I learned that in the Boy Scouts while under canvas I learned other things that aren`t for this forum there too

Nige ! I have a look of concern on my face

I agree with the other guys, it is best to get it replaced than risk anymore water damage.

Membranes are waterproof, but what tends to happen is that driven rain gets between the laps when the membrane is left exposed

If the insulation has just got a bit of water on the top, then its OK. If its sodden, then replace it. Or rather swap it for fresh stuff, then then let the damp stuff dry out, then tuft it out and then lay it back on top
