Shingles
In choosing the right roofing material for historic church buildings its important to consider the history of the structure and the materials that were used to build it. There are many different types of shingles. Some of the most popular include zinc, copper, and galvanized iron.
For roofs that are less than 50 years old a traditional asphalt shingle should be considered. These are typically warranted by the manufacturer for up to 40 years for commercial applications. They are not as long-lasting as other types of shingles.
The right shingle will ensure that your historic home maintains its charm and beauty for years to come. The right shingle can also fit in with the rest of your house decor.
EPDM Membranes
EPDM also known as ethylene propylene diene terpolymer is an extremely durable synthetic rubber roofing membrane that is a popular choice for low slope commercial roofing applications. It is available in a variety of colors and is usually installed mechanically.
Several technological advances have been made over the past few decades to improve the quality of EPDM systems. These include improved seam tapes and shear-resistant products. In addition, cured EPDM membranes have been introduced to provide enhanced weathering and durability.
The 45 mil non reinforced EPDM membrane dominated the industry for years this product was economical offered good weathering performance and had excellent hail resistance. However, its puncture resistance was not as strong as the thicker 60-mil non-reinforced version.
In the early days EPDM membranes were secured with wood nailing strips this method did not provide enough pull through strength to accommodate large ballasted projects. Eventually, manufacturers introduced reinforced EPDM sheets which contained an internal scrim.
Metal
Historic churches are often architectural centerpieces of their communities they are expected to serve parishioners for generations to come. Choosing the right roof for your church can be a tricky proposition. Fortunately, there are a number of metal roofing systems that are specifically designed to meet your needs.
The standing seam roof is one option this floats above your church building’s structure and offers a long life and weathertight performance.
A more elaborate roof design can be accommodated using stone coated metal roofing products. These products are durable, flexible and offer a range of colors.
Stone coated metal roofing products can also be used on historic mansions, camping pods and other similar structures. In addition to preserving the historical architecture, this material offers a lifetime warranty.
Another option is a screw down metal roof these require more hands on work and are not suitable for larger churches. However, this type of roofing system is highly practical for smaller church buildings.
Other types of metal roofing systems include lead coated copper, stainless steel and zinc. All of these are designed to last a lifetime and are more affordable than other roofing options.
Stone coated steel roofs
Stone coated steel roofs are a cost effective and durable roofing material. Unlike asphalt shingles this product is lightweight and easy to install it can withstand 2 inch hail stones and Class A fire ratings.
Several factors contribute to the durability of stone coated steel roofing. The first is its ability to withstand extreme weather conditions. This roofing system has been tested to withstand hurricanes and tropical storms.
In addition to its durability the product is also highly resistant to rust and corrosion. Galvalume steel is the type of steel used in the construction of stone coated steel roofs. This is an alloy made up of carbon and iron.
While galvalume steel has a good resistance to corrosion it is susceptible to scratches. You can install it unpainted or you can paint it to look like copper or zinc.
One of the best benefits of using galvalume steel is its economy. Although it is a heavy metal it is relatively easy to bend and it will last longer than most traditional roofing materials.
