Cedar shake exposure refers to the portion of each cedar shake that remains visible after installation. Because cedar roofing is installed in overlapping courses, only part of each shake is exposed to weather conditions while the lower sections remain covered.
Exposure measurements directly affect the roof’s appearance, drainage performance, and weather resistance. Larger exposures create a more dramatic architectural look but may reduce waterproofing performance if not designed correctly.
Exposure requirements vary depending on roof pitch, cedar grade, local climate, and manufacturer recommendations. Lower-slope roofs often require reduced exposure to improve water protection.
Improper exposure spacing can create vulnerabilities where wind-driven rain or snow may penetrate beneath the roofing layers.
Professional cedar roof installation follows precise exposure guidelines to balance aesthetics, durability, and long-term performance.
