Should You Repair or Replace Your Flat Roof?

The decision whether to repair or replace your flat roof is ultimately up to you. But you must first get a professional to inspect your roof. In our inspection report, we’ll include the cost to repair roof deficiencies versus the cost to replace so you can make an informed decision.

Common Flat Roofing Problems

  • Leaks & Moisture: The most common problem can often be avoided by regular maintenance and care of your roof.
  • Blowoffs & Tenting: Often associated with poor installation and/or inadequate installation.
  • Poor Installation and/or Workmanship: Be sure to research and know your installer, ask for references, and choose based on quality NOT price!
  • Lack of Maintenance: A roof like any other part of your building needs to be properly maintained. A yearly inspection can prevent leaks from third party damage (including storm damage), ice damming from clogged gutters, clogged drains and deterioration of the roof.
  • Ponding Water: Depending on the type of flat roof you have, determines whether ponding water is an issue.
  • Safety Issues: A deteriorated roof or leaking roof is a safety concern to everyone inside the building!
  • Inadequate Repairs: If your roof is under warranty, be sure to get warranted repairs. Poor repair work can lead to further damage down the road.
  • Failing Seams: Flat roofs have seams, which over time, can delaminate and pull apart causing leak points. Regular roof inspections will uncover a problem like this before it gets worse.
  • Blistering: Known as “alligatoring,” blistering is when the roofing membrane bubbles and resembles the skin of an alligator. It is caused by deterioration and is a sign that the roof needs to be replaced.
  • Punctures: Any opening put in the roof membrane is a potential leak point. A regular inspection can prevent serious damage from punctures.
