In my experience, a roof is best sealed on the outside surface.
Attempting to fiddle with the under-side of the roof seems -- to me -- like mopping the kitchen floor while the faucet leaks.
About three decades ago, we workkamped as maintenance for a beautiful new apartment complex overlooking a golf course.
* The place was built in a swamp.
* The slab was unsealed, porous, with a tendency to wick.
* As the entire complex of buildings settled into the muck, the rooves detached from the walls... slightly, but enough.
* Our furnished second-story -- with view! -- grew mushrooms in the perpetually-damp new carpet.
Curious, I removed a section of months-new sheetrock on the clerestory... and discovered an utter lack of insulation.
As far as mitigating the outside temperature, this was the equivalent of living in a tent.
And the entire empty box zone behind that wall was soggy black with mold.
Stachybotrys... a significant health threat.
Irritated, one of the paying tenants called the local televisionprogramming... they sent crews to interview renters just outside the gates of this lovely new all-inclusive community.
Insurance paid to strip the months-new buildings down to bare studs.
Everything removed went in forty-yard Dumpsters©.
The structure skeleton was doused and saturated in a mold-deterrent paint, then the whole place was re-built with new everything -- sheetrock, carpets, appliances.
Insurance paid movers to move the renters to other apartment complexes in nearby neighborhoods, paid the entire rental package including utilities and telephone, then offered major rent concessions if the renters wanted to move back into Golfcourse Villa Views Estates Leasing Homes Community.
Although we full-time lived-aboard in a conversion in the rear parking-lot next to the maintenance shop, only entering our assigned unit to shower and cook, insurance insisted we were one of several hundred injured parties.
Can you imagine the loss to the owners of a couple-three years in rents plus the bad publicity.
I dislike mold.
If I was me -- after sealing the exterior roof -- I would don my moonsuit and respirator, and Kilz the daylights out of each component while 24/7 drenching the components in the appropriate ultraviolet light spectrum.
And then, I would move someplace dry year-round.
