Goose Creek Roofing: Article About Wood Fiber Roofing Panels
Wood fiber panels are a substitute for wooden shakes or shingles. They come in rectangles of 12 x 18 inches and are pre cut with grooves and shadow lines to make them look like regular wood shingles. They are faster for Goose Creek roofing companies to install than conventional shingles, and after exposure to the weather for a few months, their color is much like the silvery color of regular cedar shingles.
Wood fiber panels can be used on any structure with a roof that has a slope of at least 4 to 12 inches. They are put on the roof lengthwise with a lap joint, where two panels meet in the same course, and a shiplap joint, where two panels of different courses meet. They can be applied over existing roofing provided that doing so does not add too much weight to the roof, but it is safer to apply them directly to roof sheathing.
Two layers of 30 pound felt needs to be laid on the decking as the first step in the process of applying wood fiber panels to a roof. Then, a drip edge is attached to the eaves. A 2.5 inch starter strip cut from the panels is used at the eaves on top of the drip edge. The panels should be cut with a circular saw that has a plywood blade.
As far as fasteners go, 11 gauge nails that penetrate ¾ of an inch into the sheathing can be used or 16 inch staples that penetrate an inch.

At least eight fasteners should be used per panel. The first should be centered over the top of the shiplap joint where the courses meet to temporarily attach the panel while the other fasteners are applied. Fasteners should not be applied any closer than 3 inches from the sides of the panels.
Courses of the panels should be staggered at 15 inch intervals. The panels have deep grooves cut in them to look like actual cedar shingles and shakes. For the sake of appearances, these grooves should not be lined up with each other between panels. There is also a score line for fastener placement running horizontally along the top of each panel and a vertical score line to help with alignment.
Valley flashing should be made of 24 inch wide metal. In addition, 36 inch wide, 30 pound felt needs to be laid down beforehand, and there should be a 4 inch exposure on either side of the center line of the flashing. Panels should be double nailed for extra stability. The topmost course of shingles on the flashing should be trimmed by 2 inches.
Finally, ridges are fitted with pre made caps made from the wood fiber paneling. These fit together with shiplap joints and are fastened at the ends with three nails.
