Problem started last year when water started leaking in 2 areas. I resealed the seams with Wet patch roofing material where i believed the seams were dried and cracked.

Overnight, the roofing seems to show condensation. Inside mainhouse temp: 64 Enclosed sunroom temp: 47 What are things i should do to fix this problem?
