How to add insulation to existing metal roof?

[Tracyree]

Is there any way to add insulation to a metal roof that's already installed? If so, what kind?

Yes but the kind really depends on your set-up. I have found that things like the blue R-board (which comes in different thicknesses) is easy to work with and can be custom sized. Having said that, I recently added "insulation" to my small coop and ended up using bubble wrap covered by cardboard - not truly ideal but the roosts in my coop are close to the roof and I wanted to use something the chickens wouldn't be interested in and/or wouldn't be harmed by if they pecked at it - so far, the cardboard is uninteresting and it has definitely helped with condensation issues and the coop is a little warmer.

Would need to know the "structure" under that metal to make a good recommendation.

In other words, what do you have room for? If the rafters are in the open you could add blue foam on the bottoms to get the R value up and still have some air movement above it, a pic showing your inside roof would be good.

Agreed. If you have pics of how the roof is held down and how it joins to the structure, that would be great. If not, could you take a stab at describing it?

Spray foam.

Thanks. I'll get a few pictures when my little one takes a nap in a few hours. I know the rafters are open, I figure I can cut the blue board and slip it between the rafters.

I used some stuff from Lowe's called Reflextic or something like that. I tried to post pictures but this new forum would not let me for some reason.

I used a staple gun to install it.
