7. Will the RoofKit EPDM membrane be damaged by
asphalt-based products?
Yes. The membrane should not come in contact with roof
cement, black jack, or other asphalt-based products.
8. What does the RoofKit warranty cover?
StaFast Roong Systems warrants to you, the purchaser
of its cured RoofKit EPDM membrane (“Product”),
and to subsequent owners of the premises on which
the Product is installed, that the Product is free from
manufacturing defects and will not prematurely
deteriorate due to weathering.
9. How long will the RoofKit EPDM membrane last?
Because this is the same quality material as our
commercial grade membrane, under normal
circumstances the RoofKit EPDM membrane has a ten-
year warranty.
10. How hot does the RoofKit EPDM membrane get
in the summer?
The membrane can get very hot in direct sunlight, but it is
able to provide watertight integrity over a wide variety of
temperatures.

11. What roof insulation board should I use as an
underlayment for the membrane?
Use a commercial grade roof insulation board, OSB
board, or plywood.
12. What do I do if I have a metal roof deck?
A minimum of one-inch roof insulation board must be
installed directly over the metal deck. Then secure the
insulation to the deck with RoofKit screws and plates,
using 10 screws and plates per 4' x 8' board.
13. Can I install RoofKit EPDM membrane directly
over felt paper?
No. A new commercial grade roof insulation board, OSB
board, or plywood is recommended.
