[RE-wrenches] L feet no flashing in shingle roof

[Andrew Truitt]

For many years I installed L-feet with galvanized step flashings adhered under the shingle row above the penetration.  This provides a mechanical barrier and can be very durable if the flashing is well secured.

Also some modules are being worked in around skylights where it is unlikely that room would be available for flashings to center over rafters.
