Lake Forest prices

Flat and low-slope prices in Lake Forest

Flat roofing is priced by the square like everything else, but the cost sits in the details — terminations, drains, and how the membrane meets every wall it touches.

What moves the price

  • How many old layers have to come off before the new one goes on
  • Where you land in the season; crews discount when the phone is quiet
  • Whether the valleys, drip edge and step flashing are being replaced or reused
  • Pitch — anything over about 7:12 needs staging and slows a crew down
  • Permit and inspection fees, which vary more between towns than people expect

Locally

A twenty-five-year shingle put on in 1982 is not a maintenance question any more. The older tracts here are past the point where patching is the cheaper answer.

Ask where the water goes and what happens when the drain blocks. On a flat roof that is not a detail, it is the design.

What best describes your home?

Different buildings need different crews, so this is the first thing a roofer asks.

Free, fast, and no obligation to hire anyone.

Questions about price

What should I do to prepare?

Move the cars out, take pictures off the top-floor walls, cover anything stored in the attic, and put pets somewhere else for the loud days. Expect nails in the driveway however careful the crew is — ask whether they run a magnet at the end.

How quickly will someone call?

Usually within the hour during working hours. If you marked the job as an emergency it goes to the front of the queue and is normally picked up faster than that.

Is this really free?

It is free to you. Contractors pay to receive homeowner requests in their area. That is the entire business model, and we would rather say so plainly than pretend otherwise.

No cost, no obligation, and never more than three contractors.
