If you are considering roofing solutions for your building in Winchester, one excellent option is modified bitumen roofing. It is a highly durable, flexible, and weather-resistant roofing material. A modified bitumen roof is ideal for low-slope roofs, which are often found in both residential and commercial structures. The installation methods for this roofing system can vary, which is an advantage in that it allows for selection of the method that fits best with your building and budget. Two of the installation methods provide "seamless" roof surfaces, which are an advantage with bitumen systems both for aesthetics and for avoiding seams that might allow water to penetrate.
The longevity and efficiency of modified bitumen roofing depend largely on the type you select. You primarily have two choices: APP (Atactic Polypropylene) and SBS (Styrene Butadiene Styrene) modified bitumen. APP employs plastic additives that make it strongly resistant to ultraviolet (UV) radiation. Although APP can work well in any region, it is most often chosen for places that receive a lot of sun because those conditions can sap a roofing material's strength. In contrast, SBS uses rubbery additives that make it a more flexible roofing option. We often recommend it for places like Wellesley, where summer temperatures can be much hotter than winter temps, and roofing materials are exposed to a lot of sun one season and lot of cold the other.
Not only does it matter what kind of roofing materials you choose, but the quality of those materials, along with the skill of your installation team, is also key to a roofing system that has any chance of being long-lasting. There's lots of weather to withstand here in Winchester, with rain, snow, and a near-constant high humidity level that sticks to your skin like glue. And those conditions leave the air and the roofs themselves open to the kinds of mold problems that our local color in Coffeetown has clearly shown can start with black, windblown, backlit-green basement algae and end with lichens, plant life, and lovely big nests of shingle-destroying birds. That makes a thorough sit-down with a local roofing expert a must before picking your materials.
