Signs you need it
- Ponding water after rain on a flat roof
- Open seams or failed flashing at rooftop units and parapets
- Ceiling stains below drains, units or roof edges

Wind gusts of 58 mph or more were recorded on 71 days near Rock Hill, higher than 75% of the cities we cover. 27 local roofers are listed.
Commercial roofing covers retail, office, warehouse, church and multi-family buildings. Most of these roofs are flat or low-slope and use single-ply membranes, modified bitumen, built-up roofing or standing seam metal.
Crews, materials and warranties differ from house roofing. A company that is good on shingles may not be the right one for a membrane roof.
Wind gusts of 58 mph or more are recorded near Rock Hill on more days than in most cities we cover. On a membrane roof, ask how edges and parapets are anchored, because wind starts at the perimeter.

A commercial roof is priced by the building: its area, membrane, insulation, drainage and rooftop equipment. One range per city would mislead.
Ask each company for a written scope and a price per square foot of roof, so bids can be compared line by line.
