Yes! In fact, there is a super-easy solution you can use to get your metal roofing looking like new again.
Yes! Metal roofing weighs less than 1.6 pounds per square foot, depending on the gauge. It will not normally overload existing roofs. Metal roofing can usually be installed right over asphalt or fiberglass roofing.
Metal roofing typically costs more upfront than traditional materials like asphalt shingles, but it quickly pays for itself through long-term savings. Its exceptional durability, energy efficiency, and minimal maintenance drastically reduce repair and replacement costs over time. A properly installed metal roof can last 50 years or more, two to three times longer than other roofing options, meaning fewer replacements and less waste. In addition, its reflective surface helps lower cooling costs, and many systems qualify for energy rebates. While the initial investment is higher, metal roofing delivers unmatched value, performance, and peace of mind over the lifetime of your building.
A properly installed metal roof can last 40 to 70 years, depending on the material, environment, and maintenance.
Here’s the breakdown:
Steel or aluminum roofing: Typically lasts 40–50 years.
Standing seam or high-end coated panels: Often exceed 60 years.
Copper and zinc roofs: Can last 80–100+ years with minimal maintenance.
To hit the upper end of that range, regular upkeep matters, washing off debris, keeping gutters clear, checking fasteners and sealants, and avoiding harsh chemicals or high-pressure washing.
The gauge is a measure of the thickness of the metal, but it’s important to remember that the metal increases in thickness as the gauge numbers decrease. B&M metals offers several gauge options. Listed in order from thinnest to thickest, they are 29, 26, and 24. It’s important to note that 29 gauge is the thinnest metal recommended for residential applications. Our heavy duty 24 gauge is recommended for those areas with severe weather, high winds, or hail.
A metal roof has no greater chance of being hit by lightning than any other type of roof. Lightning typically targets the highest point in a given area, regardless of material. In the event that your roof is struck by lightning, a metal roof can actually help prevent damage by dissipating the electrical charge. Also, a metal roof is non-combustible.
