When it comes to roofing materials, tiled roofs have been one of the most popular choices for centuries. They are durable, attractive, and provide excellent insulation. However, tiled roofs are also prone to leaks if they are not adequately waterproofed. In this article, we will explore the methods and techniques used in waterproofing tiled roofs.
Why is waterproofing important for tiled roofs?
Tiled roofs are made up of individual tiles that are installed to form the roof structure. These tiles are not waterproof on their own, and they need to be properly sealed to prevent water from seeping through and damaging the underlying structure.
Water intrusion can cause severe damage to the structure of the roof and the property itself, leading to expensive Repairs. Problems like mold and mildew growth, rotted wood, and damaged insulation are common when water is allowed to penetrate the roof.
Waterproofing a tiled roof is crucial to protect the structure of the roof and the interior of the property from damage caused by moisture.
What are the different methods of waterproofing tiled roofs?
There are several methods of waterproofing tiled roofs, and the best one will depend on the specific needs of the roof and the budget of the property owner.
