While it is not recommended to roof over a wet roof, you may be wondering if it is possible to roof over a slightly damp roof. In some cases, it may be acceptable to roof over a slightly damp roof, but only under certain conditions.


Conditions for roofing over a slightly damp roof

Solutions for drying out a wet roof

If you discover that your roof is wet and in need of drying out before proceeding with a roofing project, there are several solutions that you can use to speed up the drying process.


Here are some effective ways to dry out a wet roof:


Using fans and dehumidifiers

  1. Fans: Place fans strategically around the roof to circulate air and promote drying. Make sure to use high-powered fans to speed up the drying process effectively.
  2. Dehumidifiers: Use dehumidifiers to remove excess moisture from the air and help dry out the roof. These devices can be particularly useful in areas with high humidity levels.


Allowing natural ventilation

  1. Open windows and doors: If possible, open windows and doors to allow natural airflow to help dry out the roof. This can be particularly effective on a sunny day with a light breeze.
  2. Remove obstacles: Clear any obstructions that may prevent air from circulating freely around the roof, such as debris or overhanging tree branches.


Applying heat

  1. Sunlight: Take advantage of the sun's natural heat by exposing the roof to sunlight. This can help evaporate moisture and dry out the roof more quickly.
  2. Heat lamps: If natural sunlight is not available, consider using heat lamps to apply direct heat to the roof and speed up the drying process.


By using these solutions, you can effectively dry out a wet roof and ensure that it is in good condition before proceeding with a roofing project.


In conclusion, roofing over a wet roof can lead to numerous issues that can affect the integrity and safety of your home. It is essential to avoid the temptation to roof over a wet roof and take the necessary steps to ensure that the roof is properly prepared before installing new roofing materials.
