Final answer:
Underlayment for Metal Roofs The assertion that metal tile roofs do not require underlayment is false. Underlayment is necessary to protect from water and other external elements, enhancing the durability and longevity of the roof.
Step-by-step explanation:
The statement that metal tile roofs require no underlayment is false. Underlayment is an essential component of a roofing system, acting as a barrier that protects the structure from water infiltration and other external elements. Metal roofs are durable and long-lasting, but they still require an underlayment to prevent potential damage from moisture and to ensure the longevity of the roofing system. The underlayment provides an additional layer of protection between the metal tiles and the roof deck.
It's important to note that different types of underlayment are recommended for metal roofing systems, including synthetic products which are more resistant to water and tearing than traditional felt underlayment.
Proper installation of underlayment is critical to avoid problems such as leaks, which can compromise the structural integrity of the building. When considering a roofing project, it's always best to consult with a professional to ensure that all components of the roofing system, including the underlayment, are correctly specified and installed.
