Quick Reference Product Guide


Q. What is Mineral Surface Roll Roofing?
A. Mineral Surface Roll Roofing (MSR) is a reinforced sheet that has been coated with asphalt and top-surfaced with rugged colored granules that provide protection of the material from the sun's ultraviolet rays. In residential construction, it is ideal for low-slope roof applications such as roofing for porches, carports, patios and sheds.
Q. Does the product have slope limitations?
A. Yes. Most steep-slope and low-slope roofing materials are designed for use as water shedding systems. These water shedding systems are not impermeable, and they rely on slope to shed water off the roof surface. Adequate drainage of water from the roof surface is essential. A minimum slope of 2 inches per foot is required for the use of MRS.
Q. What colors are available?
A. White, Black, Cedar Blend, Weatherwood, Dark Brown, Red, Hickory, Slate Grey and Green.
Q. What type warranties are available?
A. Tarco warrants material to be free from manufacturing defects.
Q. Can I install MSR in cold process adhesives?
A. Yes. Mineral Surface Roll Roofing can be cold process or hot-asphalt applied.
Q. Does the product have a selvage edge?
A. Yes. MSR is offered in three options - No selvage, 4-inch selvage, and 19-inch selvage .
Q. What is the size and weight of the roll?
A. The product is 108 square foot roll to provide 1 square, or 100 square feet of roof coverage and weighs approximately 72 pounds.
