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 Oshkosh changes about commercial roofing

A large share of Oshkosh'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.

When hail is reported in Winnebago County

August has the most reports, 7 of 24. Reports run from April to October.

The county's biggest hail days

The largest stone in NOAA's record for Winnebago County fell on April 12, 2014: 1 inches, about the size of a quarter.

That day brought 2 reports, with the largest from Pickett.

A commercial roof laid before April 2014 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 EF0 on June 20, 2020 and stayed on the ground for 3.37 miles.

The strongest thunderstorm gust was 81 mph, on July 28, 2021.

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.
