Roofing in Summerville, SC

The median home in the town of Summerville was built in 2001, newer than the U.S. median of 1980 and newer than the South Carolina median of 1992.¹ 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. Most of Summerville's housing is recent: only 19% of units predate 1980 (U.S. 50%) and 20% were built since 2010.¹ 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. Summerville is about 26 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.

Owner-occupied homes in Summerville are newer than rentals: a median build year of 2002 against 1997.¹ With owner-occupied homes skewing newer, many requests are first-time replacements of original builder-grade components. Building permits in Summerville are normally issued by the town building department.^6,7 Re-roofing permits, where required, are filed by the contractor with the city before work starts.
