I have just built (the shell) of a house with steel SIPs (8" roof panels), and would like to add a metal roof and solar panels. My preference is for old style corrugated roofing (or 'wave'), and would like to know if there is any issue with this style in combination with the SIPs, and what needs to be laid between the roofing and SIPs panels (e.g. radiant barrier or other). Thank you, Ian Rossbridge
Thank you. You say that your SIP's are steel? So these are steel insulated roof panels? Why do you want to apply anything on top of them at all?
1) It's lightweight steel, and roofing is still recommended.
2) if i didn't cover with roofing, i would still need to seal all the seams in some way (currently peel and stick, which is only temporary)
3) i intend to collect water from the roof for drinking (it's far better to be channeled into the gutters, hence the question about using corrugated style)
Interesting. I would use an underlayment between the two types of panels. If you wanted to use a radiant barrier, you can but they are really only effective when facing an airspace.
OK, thanks. ian
