The best practices of patio cover construction would dictate the use of span charts from adopted residential codes for all solid saw lumber like southern pine and useful tools from the American Wood Council for cedar and other exotic species. Engineered wood spans for roofs, headers and beams would be as specified by the manufacturer of the product. If you are referring to a load bearing beams with a clear span of 18’, it may be on the upper limits of an engineered wood product unless very large or ‘doubled up’.
It can be difficult to adequately answer technical questions in forum format. Please feel free to contact me direct to discuss proper framing techniques of patio cover construction.
