Hello,
I have a mid terrace house which has one purlin on front and one on the rear. I wish to install a couple of veluxs, and am planning to re-enforce the existing rafters for trimming around the new velux.
Now this is all above the purlin, but do i need to continue re-enforcing the rafters below the perlin, i.e. into the eaves area? or is above the purling, and fixing into the purlin adequate?
Thanks
