There are two main types of solar attachments for composition shingle roofs—flashing and flashing-free. Flashing’s primary waterproofing mechanism is simple: a flat metal flashing is inserted between shingle courses and sheds water down the slope of the roof. Flashing-free attachments rely on high-grade sealants to seal penetrations in the roof, and are installed without disturbing, shingles.
This month’s Quick Tips Videos demonstrate how to install Flashkit Pro and Flashloc, Unirac’s flashing and flashing-free attachment solutions.
