Do I Really Have To???
Sooo, i am in the slow, tedious process of sealing the roof, and I'm wondering if i really need to scrape up all the old sealant?
In the case where im replacing the vents, yes, im cleaning it all up so i can start fresh.
But what about the places where 95% is ok and i really only need to retouch some cracks???
Can i get away with just adding more sealant there, or maybe just tape over it???
