If you need a new roof, you may be considering asphalt shingles. Asphalt shingles are affordable, easy to install, and relatively durable. However, as you go about shopping for these shingles, you may see some that state they are polymer modified asphalt roofing shingles, or SBS modified shingles. These shingles incorporate polymer into the design to alter the composition of the shingle and increase the benefits. Learning what the benefits are can help you make a decision as to whether these shingles are ideal for your new roof. Here are a few of the benefits. 

Helps Protect Against Tearing and Dinging

Asphalt shingles are fairly durable, but certain weather elements can affect them. Strong winds can tear the shingles, and hail or flying debris can cause dings or dents. Polymer is a plastic material that is most commonly used to make milk jugs. When added to shingles, it helps to strengthen the asphalt shingle, helping to protect against tearing and dinging. All in all, this helps the shingles to last longer and protects them against weather-related damage. 

Allows the Shingle to Be Installed in Inclement Weather

While there are many benefits to asphalt roofing shingles, one of the downsides to them is that they cannot be installed in inclement weather. If it is overly hot or freezing cold outside, the shingles should not be installed, as they expand and contract in the hot or cold, which can affect the position they are placed in. However, one of the benefits to polymer modified asphalt roofing shingles is that they do not expand and contract nearly as much as regular shingles, allowing them to be installed in inclement weather. 

Helps the Shingle Better Retain Asphalt Granules

The last benefit to polymer modified asphalt roofing shingles is that the polymer helps the shingles to retain asphalt granules. As a shingle ages, the asphalt granules on the shingle begin to wash away when it rains or fly off when it is windy. Ultimately, this can leave bare spots in the shingle that can allow water to get through. Polymer helps the asphalt to better adhere to the shingle and retain the granules, even as the shingle ages and approaches the end of its lifespan. This helps to protect your roof against water damage. 

Taking the time to learn the benefits of various roofing products will help you find the roofing material that best meets your needs while also fitting in your budget. There are many benefits that polymer adds to asphalt roofing shingles. Learning about these benefits will help you decide if they are right for your roof.
