While metal shingle technology and design options have advanced over the past decade, asphalt roof shingle quality has fallen due to the reduction of the oil (asphalt) content that roofing manufacturers are using. To save money, these companies replace petroleum products with fillers and binders. Simply stated, the lower the asphalt content, the poorer the quality of the shingles. Modern day asphalt shingles are susceptible to premature deterioration and may often cup, curl, and shed granules in as little as a year after installation. You won’t experience that with the permanent nature of metal shingles.
Metal shingles and other metal roofing designs are popular alternatives to asphalt roofing shingles due to the many benefits that metal shingles provide. Although the price of asphalt shingles may seem attractive to many Wisconsin homeowners, asphalt roofing quickly loses value and is a poor investment over the long-term.
