What is Exposure?
Roofing Glossary · Installation
Definition
The portion of each shingle that is exposed to weather, measured from the lower edge of one shingle to the lower edge of the shingle directly above it. For architectural shingles the standard exposure is 5 5/8 inches. Exposure directly determines how many courses are needed to cover the roof. Installing shingles with too much exposure voids warranties and reduces wind resistance.
