Signs you need it

The county around Sparks has 39 roofing companies with payroll, higher than 77% of the cities we cover. 28 local roofers are listed, 15 license-checked.
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.
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.

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.
