Application Instructions
Mineral Surfaced Roll Roofing-MSR
Not to be used as part of a Built-Up Roofing System.
Apply over Wood Decks when inclines of not less than 1” per foot. The deck must drain
freely at all points.
General: It is suggested that roll roofing not be applied at temperatures below 50°F. When it
is necessary to handle the material below this limit, it should be warmed before unrolling in
order to avoid cracking.
The roll roofing should be cut into maximum 18’ lengths and stacked in a pile on a smooth
surface before application until they flatten out. This is important to prevent wrinkling after
application.
Roof Deck: The roof deck shall be dry, firm, smooth, and constructed of minimum 3/8” thick
plywood, 7/16” oriented strand board (OSB) or dry well-seasoned lumber, nominal 1” thick,
not over 6” in width. Boards shall be laid close together and securely nailed. If plywood or
OSB is used it should be as recommended by the American Plywood Association,
Underwriters’ Laboratories, Inc.®, or local building codes. Plywood and OSB sheathing must
be spaced a minimum of 1/8” and maximum 1/4”.
Preparation of Roof Deck
New Constructions: Install metal drip edges at eaves and rakes. Sweep roof deck clean of
loose particles. Apply
Re-Roofing: Remove any slag or gravel. Cut open all blisters and buckles and nail both
edges to give a smooth surface, also nail edges of large cracks. Remove loose nails and drive
into second deck. Before beginning application of roofing, sweep roof deck clean of all loose
particles and dirt.
