A quality metal roof can provide decades of protection from the elements. It’s also one of the easiest types of roofing materials to maintain. But there are different types of metal roofing to consider for installation. Here is some information on the most popular two: water resistant and water shedding.

Water-Shedding Roofing

The steeper a roof is, the more efficiently it directs water off its surface. Most residential roofs are built at an angle of around 4:12 to 9:12. Meanwhile, water-shedding metal roofs are often installed at an angle of more than 3:12 to direct water into gutters and downspouts, providing ample protection from moisture. But such roofing isn’t waterproof. It requires an added layer of insulation between the roof and roof deck to increase insulation and cut condensation buildup.

Water-Resistant Roofing 

Roofs that are built at an angle of less than 3:12 need multiple waterproofing features to protect against pooling moisture. Water-resistant metal roofing creates an airtight seal on low-slope roofs. This involves using concealed fasteners throughout the structure to protect against rust and ventilation to avoid condensation. The most popular types are standing seam roofs, which feature two-inch gutters between roofing panels to direct water flow and an impenetrable airtight seal.

With the right maintenance, both roofing types will last upwards of 40 years. Selecting the proper metal roof for your home or business is a big decision, so if you have any lingering questions about what will work best for you, call the professionals from H & H Metal Products in Savannah, TN.
