Install Gravel Stops: Use gravel stops around the perimeter of the roof. These are metal or PVC profiles designed to keep gravel from sliding off the roof and into the gutters or drains.
Use Filter Fabric: Line rain gutters and drainage areas with filter fabric. This allows water to pass through while capturing gravel and larger debris, preventing them from clogging the system.
Regular Maintenance: Regularly inspect and clean the gutters and drainage points on your roof to remove any accumulated gravel or debris that could obstruct water flow.
Adjust Roof Slope: Ensure the roof has the correct slope towards drainage points to minimize the movement of gravel and enhance water flow directly into the drains.
