Durable
Long-Lasting
Metal roofing is engineered to last longer than traditional shingle roofing; it can last for at least 40 years, but usually more. You are not likely to need a repair or replacement on the roof in that time, and metal roofing can handle high winds and the Texas heat with ease. It is also harder for debris to penetrate a metal roof, which is good if the winds get too high; this protects your roof from some hail damage too.
A metal roof also does not require much maintenance, so that you will save money in the long-term on that as well.
