Hi, I am wanting to build a verandah over my deck. The verandah will run along one side of the house (an old Villa). What is the best way to fix the top bearer to the weatherboards? Can I use 160mm long 12g countersunk "Batten Screws" through the 45mm bearer, weatherboard, and into the studs or do I have to use coach bolts?
Also do I have to pack the bearer of the wall by 15mm? There will be a flashing above the bearer which will tuck under the weatherboard above and cover the top of the polycarbonate sheeting I will use for the verandah roof covering.
