Surface Preparation

Proper surface preparation is crucial for a successful installation. The roof surface must be clean and dry. Remove any debris, dust, or old roofing materials. Ensure the surface is smooth and free of moisture. Any cracks or holes should be repaired to provide a solid base for the felt sheets.

Layering of Felt Sheets

The layering of felt sheets forms the core of Built-Up Felt Roofing. This process involves laying multiple layers of felt sheets over the roof surface. Typically, the installation includes three layers:

Common Issues with built-up felt roofing

Leaks and Water Damage

Ponding Water

Ponding water occurs when water collects on the roof surface. This happens when the roof does not drain properly. Standing water can accelerate the wear and tear of the felt. It can also increase the risk of leaks.

Ensuring the roof has a proper slope can help mitigate this issue. Regular cleaning of drains and gutters is also crucial.

Punctures and Tears

Punctures and tears in the felt roofing can happen due to various reasons. Foot traffic during maintenance can cause damage. Falling debris during storms is another culprit. These punctures can lead to leaks and water damage.
