Signs you need it

Wind gusts of 58 mph or more were recorded on 140 days near Columbia, higher than 98% of the cities we cover. 26 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 Columbia 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 large share of Columbia's housing sits outside single-family houses, so flat and low-slope roofs are common. Ask every company about its experience with your type of building, not only with houses.

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.
