We highly recommend Atlas StormMaster Shingles. These are modified asphalt shingles with a rubberized compound to make it more flexible and have greater impact resistance. The modified asphalt shingle is able to withstand expansion and contraction during summer and winter months so the shingles don’t crack. StormMaster shingles also have wonderful granule retention to help make the shingles last longer as the granules protect the shingles from UV ray damage. Last but not least, Atlas shingles have 3M ScotchGard built into them. This means 10% of the surface granules are copper. These copper minerals rinse the roof every time it rains. Atlas shingles won’t streak, making for great curb appeal for the 20-30 years.
