What should you know about shingle siding? Lots, if you are planning on a house that shingle siding. Far less if your house is made of bricks. Still, who knows, one day you decide to leave your brick house (possibly after a wolf blows to try to knock it down) and move to a house where you will install cedar shingle siding or roofing. Then you’ll need to know this stuff.
Cedar Shingle Types and Grades:
Two types of cedar shingles are used more than any other. White cedar, which weathers to a more grayish-silverish color and red cedar, which weathers to either dark brown, medium brown or silver-gray depending on the weather conditions in which the house is located. Both white and red cedar are available in three grades. Premium shingles is mostly used to top off house roofs. Number 2 grading is mainly used for sidewall shingling and Number 3 grade is typically used for sheds and garages and other buildings of a strictly utilitarian nature.
Cedar Shingle Code Requirements:
Certain codes must be met when you are installing wood shingles. Spacing between shingles cannot exceed a fourth of an inch and the offset between joints must be at least 1.5 inches. Fasteners need to penetrate either sheathing or furring strips by half an inch. Wood or plywood used for sheathing must be weather-resistant and contain a permeable membrane. Clearance between metal flashing and double course shingles need to be half an inch.
Application of Cedar Shingles:
Conventional application of wooden shingles means an APA rated sheathing and a barrier for air and water. You can apply a rainscreen when applying siding by placing the rainscreen over the air/water barrier. Outside corner sheathing needs air/water barrier that wraps around the corner. Leave behind a gap of 1/8 of an inch between the shingle and trim and then seal gaps with caulk.
Alignment of Wooden Shingles:
Offseting the gaps between cedar shakes is very important so pay attention. You don’t want water or moisture seeping in between the gaps as this will lead to leaking roofs. That 1.5 gap on successive courses can mean the difference between no leaks and leaks that lead to wearing rainboots inside the house. The gaps should be not be aligned on every other course.
Stainless Steel Siding Nails:
If you want black streaking running the course of yours wooden shingles, then by all means use the cheapest nails you can find. Spend the money to gain an advantage by using stainless steel siding nails.
