Get matched with top roofers in Pauline, SC

There is a weight limit for walking on a roof, but it’s determined by your roof structure and not the roofing material, at least in the case of a metal roof. Consider that entire teams of roofers will be on top of your home during the installation, so the weight of a single person won’t compromise your roof. That isn’t the case for something like a tile roof, so a high weight limit is one benefit of a metal roof.

Metal roofs do not inherently leak more than shingle roofs; when properly installed, they are generally less likely to leak. Asphalt shingle roofs are more susceptible to leaks due to factors like wind uplift, damage from extreme weather, moss growth, and ice dams. Over time, asphalt shingles also lose their protective grit, which reduces their waterproofing capabilities. In contrast, metal is a more resilient material that stands up better to heavy precipitation and high winds. However, metal roofs can develop leaks if they are poorly installed, have improperly sealed fasteners, or experience issues from thermal expansion. For this reason, professional installation and regular maintenance are crucial to ensure a metal roof's longevity and superior protection against leaks.

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.

The formula for calculating how many squares of roofing you need is pretty easy. Take the total amount of square footage and divide it by 100. With this formula in mind, a 2,000-square-foot roof would require 20 squares of roofing material to adequately cover it.
