WE ARE CURRENTLY WORKING ON A 5 DAY TURNAROUND! (Subject to final approval)
In order to line through new trussed rafters with an existing trussed or cut roof the following five dimensions are required.
These dimensions are your responsibility. Dimension 4 is critical to ensure that the pitch is correct.
If your existing roof is a cut roof you will probably find that your rafters are birdsmouthed over the wallplate. (As above).
