What commercial roofing is, and what to ask about it

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.

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
  • A roof near the end of its warranty, with a lease or sale coming up

Ask each roofer

  • How many buildings like mine have you roofed in the last two years?
  • Do you scope the whole drainage path or only the wet spot?
  • Can you scan or core the roof to see whether the insulation is wet?
  • Who holds the membrane warranty, you or the manufacturer?

What Joliet changes about commercial roofing

Wind gusts of 58 mph or more are recorded near Joliet 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.

The county has more roofing companies with payroll than most cities we cover, so you can compare several bids on a commercial job. Ask each for references on a building like yours.

When hail is reported in Will County

March has the most reports, 28 of 111. Reports run from February to September.

The county's biggest hail days

The largest stone in NOAA's record for Will County fell on March 10, 2026: 3 inches, about the size of a teacup.

That day brought 3 reports, with the largest from Bolingbrook.

A commercial roof laid before March 2026 was in place for the largest stone in the record, so ask for a roof survey and keep it with the warranty papers.

The strongest tornado in the record was rated EF2 on July 15, 2024 and stayed on the ground for 24.9 miles.

The strongest thunderstorm gust was 96 mph, on May 23, 2020.

Why this page prints no city price for commercial roofs

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.
