Roofing across Mercer County.
Lightning Construction is a veteran- and family-owned, GAF-certified contractor serving Mercer County — a Central Jersey county anchored by the state capital, Trenton, and the university town of Princeton.
Across Mercer County's 11 municipalities there are about 150,329 housing units, and the median one was built in 1965. On average 58% of the housing in each town here predates 1980, which is the line either side of which a roof replacement stops being routine and starts involving decking and ventilation. The spread inside the county is wide: Hightstown has a median build year of 1950 while Windsor sits at 1992. Those are different houses with different roofs, and they do not price alike. Princeton carries the highest median home value in the county, at $1.1 million.
What we build against here
The weather that damages roofs in Mercer County is undramatic and relentless: summer storms, then a winter of water freezing inside small defects and widening them. Underlayment, flashing and ventilation are what stop it, and all three are invisible once the job is finished.
