15 degree felt roof

[Ric]

Morning all,

i hope you can help, I'm looking for a non penetrative mounting system for a 15 degree roof. Covering is made up of either felt or a rubberised roof.

Has anybody ever installed anything like this?

Thanks

Rich

yes, bit unsightly on a house though using loads of unistrut and foot plates

Why non penetrative though?

We have done it 2 ways:
1) Used K2 slate hooks screwed directly (S/S Spax) to the rafters, with an edpm seal underneath and used a specialist felt roofer to seal it all, - end result was better than the original
Just as well MCS 012 hasn't come (and it looks as though it isn't likely to..) into effect.

2) a really nice unistrut fabrication tied into the building to avoid sliding, and large spreaders and ballast to cope with wind load, also placing a specialist material between the spreaders and roof to negate the effect of any possible movement (scuffing).

Calculations were interesting, there again we have qualified structural engineers working for us

BayWa.re do a specialised mounting for this type of installation.

Have a look at mounting feet from Danish company Jual. Specifically designed for felt, both cold and warm roof.
Can be specified with different types of felt system to match and maintain warranty of covering. Not cheap but very effective.

Thanks guys, customer doesn't really want us to penetrate through the roof fabric, but this has given some different options.

thanks again,

Ric - do you have a parapet wall on the sides?
