Survey results - pitch roof ponding

househuntingmad

I've just had the survey back on property I'm purchasing.

Other than the usual kind of stuff which is okay, the one thing the surveyor has flagged up is the side extension roof. It's a flat roof, but notes "there is ponding in places, This is serious and could lead to damp."

Also the garage (which forms part of the extension) has "The roof covering is ponding and has been poorly patched in places previously."

So what do I do about it. The vendor is already being a PITA so part of me just feels like walking away, but not sure how easily fixable it is, or even to what extend it's problematic.

How fixable depends on why it's ponding.
It could just be slight settlement of the supporting timbers and need new timber sheeting laid flat and re-covering - or it could be that the supporting timbers are giving up the ghost and the whole thing needs rebuilding.
You'll only find out which by getting a flat roofer to have a look.

So which is it? A pitch roof or a flat roof?

I'll assume flat. Most common cause of ponding is that the slope is insufficient so water collects instead of running off to one side. This means removing the felt (assumig it's felt) and then removing whatever material it sits on and replacing it lifted slightly higher at one side, then replacing new felt.

I'm no roofer, but depending on the size of the roof and quality of replacement felt you select: £1000 - £5000?

Of course, it may be there's just a load of gunk up there eg leaves, soil, bird poop which has formed a mini dam to stop the water flowing off. Get a ladder, bucket & gloves: 20 minutes work job done!
