Flat roof repair in Northwest Indiana and Chicagoland

We inspect and repair flat roof leaks on homes and commercial buildings. If you see water stains indoors, standing water, or visible membrane damage, request an evaluation so we can assess the roof and recommend the next step.

Signs a flat roof needs repair

  • Water stains on ceilings or walls below the roof
  • Standing water that stays on the roof long after rain
  • Cracks, splits, blisters or bubbles in the roof surface
  • Seams or edges that are lifting or pulling apart
  • Punctures or tears from foot traffic, debris or storms

Where flat roof leaks usually start

Flat roof leaks often start at seams, at flashing where the roof meets a wall or parapet, at roof edges, at drains, and around anything that goes through the roof, such as vents, pipes or equipment. Water can travel under the surface before it shows up inside, so the stain below is not always under the opening. During the evaluation, we look for the source and explain the repair we recommend.

Which flat roof systems do you work on?

Flat roofs are covered with different systems, such as rubber membranes, single-ply membranes, and modified bitumen or built-up roofing. Each one is repaired differently. When you call, tell us what you know about your roof, and we will confirm the type at the evaluation.

Repair or replacement

A repair is usually the right call when the damage is in one area, such as a single seam, a puncture or one flashing detail. Replacement becomes the better option when leaks keep returning in different places, the surface is cracked or blistered across the roof, or the insulation under the membrane is soaked. We explain what we find and which option we recommend.

Estimates

The on-site evaluation is free, and the estimate has no obligation. The cost of a flat roof repair depends on:

  • The size of the damaged area
  • The roof system and its condition
  • Whether insulation or decking under the surface is wet or damaged
  • Access to the roof

We give an estimate after we see the roof.

Common questions

Is standing water on a flat roof a problem?

Some water right after rain is normal. Water that stays for days adds weight and wears the surface faster, and it can find its way into any weak seam. It usually means the roof is not draining well.

Do you repair flat roofs on commercial buildings?

Yes. We repair flat roof leaks on homes and commercial buildings.

Can you give me a price over the phone?

We give estimates after an on-site evaluation, because the cost depends on the roof system, the size of the damage, and whether water has reached the insulation or decking. The evaluation is free.
