They are cut to the same length as the brickwork they sit on a half lap joint is great for the corners to be fixed to.
Pitched roof wall plate roof.
Trussed rafter roofs and traditional cut roofs should be supported on timber wall plates.
Comprises a series of rafters fixed to plates at the top of a wall and the rafter feet are nailed to a wall plate which distributes the load evenly across the supporting wall.
The wall plate allows for roof pitch adjustment between 2 5 25 degrees making it suitable for almost all lean to roof applications.
This is part two of the porch build where i am doing the roof.
Trussed rafters should only be supported at the junction between the ceiling tie and rafter unless.
Easy to install and available.
Brief descriptions of these pitched roof types are given below.
Designed with flexibility in mind this lean to roofing system is suitable for a wide variety of applications.
Getting the wall plates or top plates as they are sometimes called right is important because all the ceiling joists roof rafters hips etc.
Dedicated screw lines make fitting to the wall simple and trouble free.
In order for all the roof components to work they must be square parallel level and fixed down properly.
For example starting from the wall plate and working towards the centre or ridge if you measured in a level 12 inches or 30cms and then measured directly up at 90 and at that point the roof was 6 inches or 15cms high that would be a pitch of 6 12 or 6 in 12 and can also be simplified as 1 2.
