When a roof is getting close to the end of its lifespan, it may need to be replaced. When homeowners replace a roof, they have the option of choosing a different material than what they had before. The following is a comparison of the two most common roofing materials, asphalt and metal.
Which Roof Type Has A Longer Lifespan?
Asphalt shingles tend to last from 10 to 25 years. They last longer in areas with mild, dry climates, and homeowners can get the most years out of their asphalt shingles by keeping up with maintenance. If any shingles get cracked, get pulled away from the roof, or lose their granules, they should be replaced right away to make sure they don’t let moisture get through to the underlayment and decking. Metal roofs, on the other hand, are highly durable and can last anywhere from 30 to 70 years.
Which Roofing Material Requires More Maintenance?
As mentioned above, asphalt shingles require regular maintenance. Any damage to a shingle makes the roof vulnerable to damage at that point, so regular inspections are required to check for shingles that need to be replaced. Metal roofs also require some maintenance since metal can rust and corrode over time. Thus, a metal roof needs to be kept clear of debris, like leaves, pine straw and branches that can hold on to moistures. They should also be checked regularly for nicks where water can get in and cause rust.
Which Type Of Roof Costs More?
Asphalt shingles are the least expensive roofing material, but they have the shortest lifespan. While metal roofs have a higher purchase price, they last longer and can thus be considered a better investment.
Which Roof Is More Energy Efficient?
The most energy-efficient roof for a homeowner will depend on the location of the home. In regions where winters are long and cold, asphalt shingles are a good choice because they keep heat inside the house, helping homeowners save on their heating bills. Metal roofs, on the other hand, can be a better choice for hot climates because they reflect heat away from the house and lower air-conditioning bills.
