Cedar Impressions on a Steep Rake
A solid nailable substrate is required for this product. The substrate 
must have the nail holding equivalent of a 3/4" penetration of a nail 
into solid wood.
Installing Cedar Impressions on 
Non-vertical Walls
Cedar Impressions must never be used as a roofing material. 
However, the panels can be used on non-vertical applications that 
meet the following conditions:
• The non-vertical wall must be decorative and not functional.
• The non-vertical wall must not be greater than 20° off the 
vertical (no less than a 70° angle).
• The top of the wall cannot be higher than 30' above grade. 
Because of different wind-load requirements, your local 
building code may stipulate a lower height. Use the lesser 
of the two heights.
Before you install Cedar Impressions on a non-vertical wall, install 
a non-binding, self-adhering underlayment or waterproofing 
membrane. Cap the uppermost edge of the top course of siding to 
prevent water from getting behind the siding. Flash all accessories 
to shed water away from the substrate. Siding alone is not meant 
to be a watertight barrier.
