Key Factors to consider when choosing your Slate Roof
Size & Thickness
When choosing the size and thickness of your slate roofing system it is best to first determine whether or not your home can withstand the weight of standard size slate shingles. Most homes are capable of supporting the standard thickness slate, 8lbs. per square foot, without modification, but it is best to investigate before making a final decision on the system. In situations where the weight is too high, bracing of rafter spans is usually relatively inexpensive.
Color & Blend
When determining the best color of slate to compliment your home, you must first choose from Weathering Slate or Non-Weathering Slate (more information below). Weathering slate provides natural earth tones of bronze, browns, buffs and cream colors which eventually become a blend on the roof. Non-Weathering slates hold their colors and tend to be darker colors of blacks and grays.
Weathering & Non-Weathering
Weathering slates will change color as they age with most weathering occurring in the first 1 to 3 years but can continue to change infinitely. Weathering slate provides the natural earth tons and the colors tend to be on the lighter end of the spectrum with light grays, greens which can provide a more natural “country cottage” or “old world” look to a home. Almost all domestic slate weathers to some degree. Non-Weathering slates hold their colors and tend to be darker.
Mixture & Uniform
Mixture Slate roofing is the combination of two or more widths of slate roofing tiles randomly installed to provide a “broken” or random pattern. Random width is most common on residential installations and tends to the more natural look. Uniform Slate roofing is when a single width of slate tile is installed on the roof. In this case the slate shingles align to create a more uniform pattern on the roof and provide a more formal style.
