Best roofing system for a garage

[craigtdann]

Hi,

My house and garden are raised up from the road and there is a very steep bank at the roadside before levelling off into my garden. The levelling off is slightly higher than the height of a garage.

I intend to cut a dugout into the bank and build a double garage, but would like to put the lawn back so it runs on to the roof of the garage - i.e from the garden you can't see the garage it just looks like lawn.

Can anybody recommend any roofing systems which would be suitable for the load and for the span?

Do I need any special membranes?

Any help appreciated.

Thanks

Not cheap..

Will need either more beafy supporting timbers or go for a lightweight sedum type system..

you need lots of special membranes. Don't forget to factor in the extra costs of the retaining walls.

Best bet would be to contact an SE because BC will want calcs if you are planning to retain the earth with the garage wall. ?He can then also do you some for the roof structure.

As Static said, Not cheap.
