Hello,
I'm putting an insulating layer on the roof of the house by taking the roof tiles and battens off, laying the insulation, 6 cm thick, and then new battens and then replacing the tiles. At the valleys where the house roof connects to the barn roof, which is not being insulated so there will be a 6 cm difference in height, I am wondering how far through to run the insulation. Should it butt against the barn roof, stop mid-way or stop short of the barn roof?

Greetings,

Don Wagstaff

Not knowing how the buildings are laid out (I am assuming a T shape where all ridges and eaves are level), I would butt it up against the barn roof. The eaves could be adjusted, but the house ridge will be higher than the barn ridge.

Hello,
Well, a T shape is more or less the configuration. Let's call it an L though. Ridges and eaves are not really a concern in this situation. Not being so good at spacial visualization, what I imagine the effect of butting the insulation tightly against the barn, matching the cut to the angle of the two adjoining surfaces would be is to shift the bottom of the valley so that the corner where the two walls meet under the roof would no longer be aligned there. Other than that I can't see any other problems with this solution. Thanks, I'll go further from here on that basis.

Hello,

Still working my way up to these valleys but at this point about half the roof in insulated and re-tiled. To bad the weather has turned nasty on me.

Neat, I like how you used trim to hide the extra thickness.

Re-doing a roof, so to speak, is a big work. Here is the actual result of beefing up the trimmings to compensate for the addition of 6 cm insulation applied to the exterior.
