Any issues with putting the synthetic felt over the existing 15# felt if you know the deck is good?
If you know for sure the deck is fine its ok. Alot of crews do that on really steep stuff like 12/12 roofs.
So, if you know the deck is good...
And you don't even have to go under the felt...
You can also surely put a second layer of 210 3-tabs on as well...
False. Not sure why you're choosing this hill to die on. Edit- Yes, you can overlay them, it's just stupid. It's saves you very little money, and reduces the life of the shingles. It's also illegal in most cities. Putting a second layer of felt on is usually only down for increased footing for steep pitches, and has nothing to do with cost.
