The main visible difference between a traditional slate roof and a hybrid slate roof is the exposure of the slate. The exposure is how much surface area you can see on an individual piece of slate. Using 18” slate, the traditional slate method exposure is 7.5”, while hybrid slate method exposure is 11”.
The main unseen difference with a traditional slate roof vs. a hybrid slate roof is that a hybrid system uses the addition of a black film in between each coarse/row of slate. Because we are able to “stretch” the exposure with a hybrid system, the entire roof weighs about 40% less than a traditional slate system, but still offers the beauty of a traditional slate roof.
