No. 3032Anonymous 26th February 2022 Saturday 2:47 pm3032What's an inch between friends?
Storms C, D & E destroyed some clear roof panels here - I bought new ones but they're on a 4" pitch, not 3" like I need, and it's really not bodgeable. They're individual clearish panels in a fibre cement (probably asbestos, joy) roof.
Any hints how to find what I need? (2 foot 6 wide or more, 2m long or more, clear or translucent, preferably polycarbonate but will take what I can get, although the installation is such a bitch that I doubt PVC sheets will survive the wrestling.)
Pitch s the word I'd use to describe the corrugations, but it's overloaded in roofing sites enough to not be a useful search term, and' '3' is fuck all use.
You want British standard 3"/10 or 3"/12 sheets. You probably bought Onduline sheets which are metric - 95mm spacing iirc. Get the proper fixings and edge sealant tape, otherwise it'll leak like a sieve.
76mm, not 75mm, gets the solution. Corrapol low profile, for anyone in the same hole.
If I had the cash I'd have someone remove all the asbestos sheet, it's pretty crumbly. Fuck's sake, I was hoping to get away with it for a few more years.
Cheers - sheets ordered, and an asbestos test booked. The old 'leave it alone and it's harmless' plan may not work for much longer. I'm perfectly happy sticking a new roof on, but old asbestos gives me the willies.
Also, what's up with 95mm? It's nothing sensible in imperial or metric.
Removing an asbestos cement roof is relatively low risk if you approach it sensibly. It's not licensed work so you can legally do it yourself. Wear a disposable suit and a proper respirator, wet everything down before starting work, wrap everything in two layers of thick polythene as soon as you remove it, wipe everything down (including your suit) with damp rags after finishing work. You'll want two pairs of hands to avoid dropping the sheets and you will need a licensed skip to take it away.
