A properly installed cedar roof will protect your structure from rain, wind, and other forces of nature. This is because the underlying principle is borrowed from nature itself. Cedar plates are stacked on the roof like the scales of a cone from a coniferous tree, overlapping in three layers. With this installation, if the rain is swelling the wooden plates, the entire surface expands further and closes any gaps, preventing the slightest drop of water from penetrating inside the outside. In dry weather the cedar plates dry out, opening and bending, creating conditions for the airing of the assembly and rapid evaporation of moisture from its surface. Quite possibly, you may have observed this phenomenon in a pine forest when, after a rainfall, the uneven and jagged surfaces of pine cones become closed and smooth. Then when the pine cones dry out, the opposite effect occurs and they open up again.
Cedar Roof InstallationThe installation of cedar shakes and shingles:
- First, the underlayment must be installed
- A drip edge is then nailed along the eaves
- The lower portion of the roof is then covered by a protective ice/water shield, which overlaps the drip edge
- Then, the roofing above the shield is covered with 15 pounds felt, which bottom edge overlaps the ice/water shield
- Then the shingles can be installed at a 9-inch exposure and in straight, single courses
- The first ‘starter course’ consists of 12” wide shakes, and its butt (thick) end must extend ½” beyond the drip edge
- The application of the second course of shakes begins over the starter course directly, meaning that the butt of the starter course must be even with that of the second course
- The joints between shakes should never be less than 1 ½ inches, on all four sides
- No joint should be left open to the weather, which is ensured by the overlapping of the shakes. Moreover, every nail is covered, as the shakes are installed
- Roofing caulk is finally used to glue on the last row of shakes. This helps cover all of the nail heads without creating any new ones.
Regardless of the shakes’ width, all are secured with 2” nails, which can be hot-dipped galvanized, stainless steel, or electro-galvanized.
In order to ensure a proper fit around ventilation, along with the rake, near flashings, and in valleys, shakes must be cut. A saber saw is used for curved cuts and a circular one for straight lines. Galvanized valley flashings are applied to the roof’s valleys, while rubber fitting boot and caulk under the boot are used to flash the pipes or vents.
Galvanized ridge flashing is used along the ridge and the ridge vent, and finally, all exposed nails are secured by being covered with caulk. This occurs throughout the installation process.
