STEP 2 - Installing Liberty" Base Sheet... Nailed Base or Adhered Base?
=� 1. Align Base Sheets... Starting at the lowest point of the roof where there are gutter or fascia edges,
extend the base sheet over and down the fascia fullyY behind the metal edge or gutter height,
L, fastened along roof edge and along fascia 9" o.c. Ivlmimum overhang is 1 . Be in with 1/i vndth
((19 11/16) sheets in 2-ply systems. Use 1/3 width (13 1/8') starter sheets in 3 fly systems and install
2nO ply (interply sheet) starting with 1IR width (1911/16') sheets to maintain side lap offsets.

2. Install MA Base Sheet (Where Required)... using nails with 1' cap heads. Fasten every 9" in the lap
and stagger 2 rows in the field every 18' (see Fasfening detail). Cover the entire roof area.
3. Install Self -Adhered Base Sheet... by aligning sheets properly before removin the release liners. Roll
out sheet and let ft sit or "relax" for at least 30 minutes to minimize the potential for wrinkles that can form
during installation. Remove one side of the release liner at a time.
4. Overlap Following Rows of Base Sheet... horizontalry, (side lap l by using the line found on the base
sheet. Remove release films from top and bottom half of sheet in [um, carefully rolling back into position
to maintain over)ap. Where no line is ppresent, overlap by 3'. Overlap vertically (end laps) by at least 6'.
Make sure all end laps are at least 18" apart.

to maintain overlap Remove selvage edge release film prior to installing bottom Half of sheet and
finishing the side lap.
S. Roll the Cap Sheet Into Place... using a weighted roller. This improves adhesion to the base sheet
and ensures properly sealed laps.
Common Mistakes (and How to Avoid Them)...
ANot Priming the Edge Metal... can cause the cap sheet to peel away at the edges. Always prime
