Tar paper, #15 felt, use staples or nails?

Dark shingles should last as long as lighter shingles given that they are installed on a house that has a properly vented attic. Proper attic ventilation is the key component to a longer lasting roof.

We use UL 15lb and fasten with staples but prefer buttons.Button caps a.Ka "Greenies","Orangies" griprite.I was thinking of a hand stinger,but changed my mind.I have a couple guns for the caps.I am very satisfied as long as the caps stay the same price.1 of the small boxes will do about 20sq.

30 lb felt is waste of money, if you're using i&w in the vallys, eaves and walls.

I know we all have different opinions on materials but why would you say 30# felt is a waste of money? it clearly works better and lasts longer. Using 15# felt is a very cheap way to install a roof. And in addition, Why would you skimp on felt in the center areas of a roof slope then go with ice and watershield every where else? That doesn't make sense.

that would be like putting on beautiful seamless gutters and using plastic hangers.......

We tear-off a lot of 45yr old roofs with 15# felt and two layers of shingles.
By todays standards every shingle one of theses roofs should have failed.
9 out of ten of these roof have no plywood damage.
The times there is plywood damage it's at the eaves, valleys or walls.
What advantage is 30# felt?

Interloc

Eaves- probaly no dripedge.
Valleys- probaly a closed cut one.
Wall- flashing issue no doupt.
30# probaly has nothing to do with it.
