    Alternative to counter batten on sarkin roof?

    Um, who mentioned 9mm battens? The battens are 25mm*50mm I think (could be 45mm) and sit firmly on well supported 12mm ply. More than enough, by a long chalk. Confirmed by Forticrete tech support a few days ago.

    Alternative to counter batten on sarkin roof?

    We are where we are with this build. Rafters are up, sarking board fixed, roof-felt on. We're not going to entertain the cost of reversing what's been done based on the probably slim chance of it causing issues. I am hoping to find someone who knows what they're doing ....on here. Just...

    Can I kill two birds with one stone here I wonder? Is there something I can place between the batten and felt where I nail that will lift it up and waterproof the hole too? Will a couple of mill do it do you reckon? I've been reading the 6mm is recommended minimum.

    Alternative to counter batten on sarkin roof?

    We're building a lean-too shed approx 4.5m long by 3.5m wide. The pitch is very shallow, about 11degrees. We're using Forticrete Centurion tiles which work to 10 degrees. Due to some mix ups between the planning (or lack of it) and work being shared between 3 people (never doing it like that...
