Bridging refers to a condition where the roofing material does not lay flat against the roof deck, but instead forms a bridged area or gap between the material and the deck. Bridging can occur for a variety of reasons, such as inadequate or improper fastening, improper installation, or structural problems with the roof deck or supporting structure.
Bridging can be a serious problem in roofing, as it can compromise the integrity of the roof system and increase the risk of water infiltration and other types of damage. Bridging can create areas where water can collect and pool, leading to the deterioration of the roofing materials and the roof deck itself.
To prevent bridging from occurring, it is important to ensure that the roof is properly installed and fastened, and that any areas of damage or deterioration are promptly repaired. Proper ventilation and drainage can also help to prevent the buildup of moisture, which can contribute to the formation of bridged areas.
If bridging is already present on the roof, it may be necessary to remove the damaged materials and replace them with new materials that are properly installed and sealed. It is important to address bridging as soon as possible, as it can quickly lead to more serious damage and compromise the overall performance and durability of the roof system.
Overall, bridging is a serious problem in roofing that can be caused by a variety of factors. Proper installation, maintenance, and repair of the roof can help to prevent bridging and ensure the continued durability and performance of the roof system.
