What pound felt should be used when installing a new slate roof in Missouri? | ||

we use & recommend 30# U.L. installed with copper or galv. nails as sparingly as possible. any other questions or need a slate contractor's opinion feel free to call me. Jason @ Jayco Roofing & Restoration Inc. St. Louis, Mo. 314-497-3779 | ||

We also use 30 lb standard slater's felt, nailed on with EG roofing nails. Joe Jenkins | ||

Or, from personal experience on my own roof, 30lb just short-stapled works too if the roof goes on quickly before the 30lb can be torn off by wind. But maybe that's against code!!? All the subsequent slate (or shingle) nails will be more than adequate to stop the 30lb from sliding around underneath, even after the staples rot! For small quick jobs, I just don't see the need for that fancy, high-falutin, plasic-washered, over-kill nailing down of the underlayment ... stapling is so much easier on the roof boards. | ||

Stapling is fine if the slate is going on immediately. The felt only has to be held in place until the slate is installed. If the roof will only have felt on it for a long period of time, say over the winter months, we half lap the 30 lb and nail it every 6" on the exposed edges (plus we install a vertical - not horizontal - batten board on the roof edges to prevent wind lift). For extra insurance, you can skim trowel-grade roof cement over the exposed nail heads. The nails can be electro-galvanized as they won't matter once the slate is installed. |
