Mineral Surfaced
Roll Roofing
Not to be used as part of a Built-Up
Roofing System. Apply over wood decks
when incline is 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 a 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 ¼".
Preparation of Roof Deck
New Construction: Install metal drip edges at
eaves and rakes. Sweep roof deck clean of loose
particles. Apply one layer of underlayment of #15
asphalt saturated felt over the entire roof surface.
Lay in a horizontal manner lapping each course
over the lower course 2"; and where ends join, lap
them 4". Lay underlayment at least 6" over all hips,
ridges and valleys.
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 sound deck.
Before beginning application of roofing, sweep roof
deck clean of all loose particles and dirt.
Application
Nails: Use large head corrosion-resistant nails, 11
-
or 12-gauge, with heads at least
3
8" in diameter.
Nails should be long enough to penetrate into
wood deck at least ¾", or completely through
plywood deck or OSB a minimum of
1
8".
Concealed Nail Method
Edge Strips: Place 9" wide strips of roll roofing
along the eaves and rakes, positioning them to
overhang the deck ¼" to
3
8". Fasten the strips with
rows of nails located 1" and 8" from the roof edge
and spaced 4" on center in each row.
First Course: Apply the first course with a full-
width strip of roll roofing so that its lower edge
and ends are flush with the edge strips at the
eaves and rakes. Fasten the upper edge with nails
so that the next course will overlap them a mini-
mum of 1". Lift the lower edge of the first course
and cover the edge strips with lap cement. In cold
weather, turn the course back carefully to avoid
damaging the roofing material. Press the lower
edge and rake ends of the first course firmly into
the cement-covered edge strips. Work from one
side of the sheet to the other to avoid wrinkling
or bubbling.
End laps should be 6" wide and cemented over
the full lap area with the recommended cement.
Nail the underlying sheet in rows 1" and 5" from
the end of the sheet with the nails spaced 4" on
center and slightly staggered. End laps in succeed-
ing courses must not line up with one another.
Second and Succeeding Courses: Apply the sec-
ond course so that it overlaps the first course at
least 2". Fasten the upper edge to the deck, cement
the laps and finish installing the sheet in the same
manner as the first course. Follow the same pro-
cedure for each successive course. Do not apply
nails within 18" of the rake until cement has been
applied to the edge strip and the overlying strip
has been pressed down.
Hips and Ridges: Trim, butt and nail the sheets
as they meet at a hip or ridge. Next, cut 12" x
36" strips from the roll roofing and bend them
lengthwise to lay 6" on each side of the joint. Do
not bend the strips in cold weather without first
warming them. These will be used as “shingles”
to cover the joint, each one overlapping the
other by 6" as shown in Figure 2.
Start hips at the bottom and ridges at the end
opposite the direction of the prevailing winds. To
guide the installation, snap a chalk line 5½" from
and parallel to the joint on both sides. Apply
asphalt plastic cement evenly over the entire area
between chalk lines from one side of the joint to
the other. Fit the first folded strip over the joint
and press it firmly into the cement, driving two
nails 5½" from the edge of the end that will be
lapped. Cover the 6" lap on this strip with lap
cement. Then place the next strip over it. Nail
and cement in the same manner as the first strip.
Continue the same procedure until the hip or
ridge is finished.
