Longevity and Durability: Metal roofs can last 40 to 70 years, depending on the installation quality and material. A metal roof can withstand unpredictable and intense weather conditions, including heavy rain, ice, snow, high winds, and hail.
Energy Efficiency: Metal roofs are reflective. Rather than absorbing the sun's rays, they reflect them. This helps pretty significantly in lowering cooling costs by up to 25%, especially in climates that are hot. There is also a special coating on some metal roofs that makes them more reflective lowering energy costs even more.
Low Maintenance: Once installed, metal roofs do not really require any maintenance. They are not prone to cracking, warping, and cannot rot. Insect damage and mildew will not be an issue either. An occasional inspection and cleaning is all that is required to keep a metal roof in good shape.
Eco-Friendly: Metal roofs are often made from recycled materials, and the roof can be recyclable at the end of its life. Because of this, metal roofs are an environmentally friendly option when compared to asphalt shingles, which are just thrown away.
Fire Resistance: Metal roofs have a Class A fire rating, which is the highest rating possible. They provide another layer of safety to your home.
Cons of Metal Roofs
Higher Initial Cost: Installing a metal roof can cost two and sometimes three times more than installing a traditional roof with asphalt shingles. Due to longevity and limited maintenance requirements, many homeowners still opt for metal roofs.
Noise Levels: Metal roofs are noisier during storms or when something falls on them. Additional insulation can solve this issue, but that adds to the installation cost.
Expansion and Contraction: Expansion and contraction can happen because of temperature changes. Fasteners can loosen over time because of this. Regular inspections and maintenance is important to prevent leaks.
Difficult to Repair: While metal roofs are tough to damage, repairing them can be a bit more tricky and pricy than shingle roofs. If the roof is many years old, matching the color and material can sometimes prove to be difficult.
