Common Flat Roof Service Questions

Technically, a flat roof can be raised, but it’s extremely expensive, and there would not be much of a point. Most homeowners raise the roof in their homes to access the space between their existing ceiling and the roof, but flat roofs don’t have this space. Therefore, you can raise a flat roof, but it involves heavy structural modification.

Yes, most flat roofs include warranties for materials and installation. Confirm terms with your contractor.

This depends on the design of your roof and any preexisting issues. If you have water and puddles pooling, no matter the roof type, apply a coat of sealant immediately. Beyond that, seal a flat roof every five years, though constant rain and snow hasten this time frame to three or four years. Add a few years for sloped roofs, waiting six to eight years between applications, as water does not pool with these designs.

Rolled roofing averages $1.50 to $3 per square foot, with an average installation price of $7,500. This is less expensive than the normal cost for new roofs—traditional styles run between $4.35 and $11 per square foot, averaging $14,400.

A modified bitumen roof is the most affordable option for a flat roof, costing between $4,000 and $8,000 for a 1,000-square-foot roof. However, this material also has the shortest lifespan of the flat roof materials, so you’ll pay more for ongoing repairs and replacements than you would with most other options. Hire a roofer to help you choose a flat roof material that fits within your budget and will stand up well to the climate in your area for the best value.
