Roof Flashing Selection Chart

To determine which Roof Flashing you require. work out the pitch of your roof.

Roofs with low inclines require a 0/12 - 6 / 12 Roof Flashing.

Roofs with steep inclines require a 7/12 - 12/12 Roof Flashing.

To calculate your roof pitch use one of the 12 inch rules to measure the number of inches ( A ) from the end of the other ruler down to the roof. ( as shown in this illustration )
For example: if ( A ) equals 3" the the roof pitch is 3/12.
