Hi guys, I am building a Gazebo, and I am nearing the roofing stage of my project. I have the 4 beams in place and I am now ready to order my prefab roof trusses. I am having a 4 sided hiped roof which will sit onto of 4 roof beams which have and outside measurement of 5110 x 5110. (square shape). I am having a 300mm eave and a 20deg roof pitch. My question is what overhang will I allow on the trusses? I am worried if I get the trusses made to 5110 then things might get a bit tight...
