With proper installation, a metal roof should not be loud when it rains. The contractor inserts a strong sheathing between the metal roof and the existing surface, reducing noise from rain, hail, and other weather conditions.
While metal roofs have many benefits, there are some drawbacks to consider. If you live in an area with extreme weather conditions, your roof may incur dents, cracks, and other damage. Depending on the metal material you choose, it may also rust or corrode over time.
You can install metal roofing over existing shingles. If the shingles are in good condition, you can ask the contractor to perform a roof overlay rather than pay for the cost of a roof replacement. An overlay can help you cut labor costs by up to 25%.
To ensure your metal roof reaches its maximum lifespan, schedule cleaning once yearly and sealing every 10 years. The average cost of roof cleaning is between $300 and $600, while roof sealing costs range between $500 and $2,400.
