Prices from 8 Georgia roofing companies
This is a typical range, not a quote. The sections below explain what moves the price for this job. The dot marks the middle price, and a + means some businesses charge more.
What the job involves
A flat roof is rarely level. It has a slight slope toward drains or edges so water runs off, and its waterproof covering goes down in large sections that are joined at seams.
Low-slope roofs are grouped with flat ones because shingles need more pitch than they have, so a porch or an addition with a gentle slope often gets a membrane too.
Many roofers focus on shingles, and a flat roof may go to a crew that installs membranes regularly. This figure is per square foot of installed roof, so the total depends on how large the flat area is.
What moves the price
- How the membrane attaches
- Some membranes are glued down, some are fastened through the insulation and some are held in place by weight. The method depends on the roof and the product, and it changes materials and labor.
- Seams and edges
- Seams may be welded with heat, glued or sealed with tape, depending on the membrane. Edges and places where the roof meets a wall each need their own metal trim and flashing, which add to the bill.
- Small area or whole roof
- A flat section over a porch or an addition is a different job from a whole flat-roofed building. Small areas can cost more per square foot, because setup and some materials do not shrink with the roof.
- Things on the roof
- Vents, pipes, skylights and equipment such as an air conditioner each have to be flashed, or lifted and set back down. More of them means more labor.
- Recover or tear off
- On some flat roofs a new membrane can go over the old one, and on others the old roof has to come off first. The roof's condition and the maker's instructions help decide, and a tear-off adds cost.
Getting a quote
Questions to ask each roofing company before you compare prices:

- How will the seams be joined, and what is done at the edges and where the roof meets a wall?
- Does the old roof come off, or does the new membrane go over it?
- Is insulation in this price, or only the membrane?
- Where will water drain from the roof, and does the quote change any drains?
- How often do you install this type of roof, and can I see a recent job?
