    Default Batten Overhang

    Looking to replace my verandah's polycarbonate roof with colorbond. The verandah is treated pine with 60cm rafters spacing. Currently the battens end flush with the end rafters. Is it kosher to extend the battens beyond the rafters say between 30 to 60cm? I would cut the existing battens back so I can secure the new overhanging battens over 2 rafters. The verandah doesn't need to be trafficable.

    The reason for all this is to give the deck a bit more rain protection as the current roof is just flush with the edge of the deck.

    too far for a batten imho, just put in another rafter to achieve greater coverage?

    Battens can overhang to 1200mm but you need to get the details from the as1684 span tables.
    PM me with your batten size and spacing and I'll let you know

    Cheers pulse

    Depending on the width/depth of your rafters you may also be able modify (check out) the last rafter to install 'outriggers' under the extended battens, such as those built to create eaves over gable-ends.
