Remark about waste, hips & ridges and starters strips:
We advise you to order an extra of 10% material for a gable roof and 15% for another type of roof because the previous calculations do not include the quantities of shingles required for the hips & ridges, the starter strips, waste from cutting and waste from special roof details.

Remark:

Overlap:
When the roof slope is between 15° and 20°, we advise you to use 'Easy Underlay' (add 50% for the overlap).
When the roof slope is between 21° and 85°, we advise you to use 'Easy Underlay' (add 5% for the overlap).

| Number of bags (200 nails):
|
| To install your shingles you will also need corrosion resistant nails of 20 mm in length and a head diameter of 10 mm. The shaft should be 3 mm in diameter and barbed.

| Number of tubes:
|
| Note that steep slope application (> 60°) or high wind areas require
extra nails and hand sealing with Easy ShingleŽ Stick. During cold weather application, extra mastic must be added in the same manner.
