Why do cedar shakes need maintenance?
Medium resaws are the most popular cedar shake in Calgary. The shakes dry out and check(crack) and expose the interply felt between courses. Over a period of time the felt will deteriorate and expose the sheathing, and left unattended can cause interior water penetration(leaking). Over the years, cedar has built up natural enzymes that fight rot, however left alone or unmaintenanced over a period of time, a cedar shake will start to rot. Another problem is ridge cap staples become loose and need refastening. Flashing intersections need re-sealing and a general checkup will assure maximum longevity.
