Roofing in North Charleston, SC

The median home in the city of North Charleston was built in 1996, newer than the U.S. median of 1980 and newer than the South Carolina median of 1992.¹ Most of North Charleston's housing is recent: only 32% of units predate 1980 (U.S. 50%) and 25% were built since 2010.¹ Newer roofs are often still inside a manufacturer warranty, so the first question on a repair is whether the original installer's workmanship warranty or the shingle warranty applies. Annual precipitation is about 53 inches, with 16 days a year of an inch or more.^2,3 Where heavy-rain days are common, the quote should name the underlayment and the valley and flashing details, which is where most leaks start.

Measurable snow is rare (about 0.3 inches a year).^2,3 Summers run hot, with about 64 days a year at 90°F or more and 1 at 100°F.^2,3 Long hot seasons shorten the life of dark asphalt shingles; a quote should state the shingle's rated wind and heat performance and whether a lighter color or a metal system is sensible. North Charleston is about 17 miles from the ocean or Gulf coast in a straight line.^4,5 Near the coast, fastener grade and wind rating matter: ask for stainless or hot-dipped galvanized fasteners and for the installed wind rating of the shingle system.
