Sarking

[annieigma]

Just been looking at sarking, loads of different stuff on ebay, but only need to cover around 10 sq mtrs, don't need a 50mtr roll by 1.5 mtrs, not doing a housing estate, just the sun lounge. is there some we should avoid, or will anything do? its tiles, 3 mtrs by 3.5.mtrs.
thanks,Annie,

In your situation, Annie, I would strongly advise a "breathable" membrane. Don't be tempted to buy, for instance, a 1m x 15m roll of something like "Protect A1" for around £17.

You can use a non-breathable, but you'll spend way more than the money you save, on roof ventilation products.

This is the smallest roll I can find.....
