Most homes and roofs have load bearing capacities. This refers to the amount of weight a structure can safely support. If the structure's capacity is exceeded, major problems will develop. In the case of a Charlotte roofing, too much weight may cause a roof to collapse.

The roof depends on a variety of structural components to maintain its weight and remain in proper position. However, it's not just roofing materials that require support. Many people install a variety of items on a roof, such as satellite dishes, solar panels and ventilation fans. In the winter, the roof may also have to support the weight of large amounts of snow.

Even if people don't install many items on their roof, the structure still has the potential to exceed its load bearing capacity. This commonly occurs when roofing materials are too heavy or after the formation of standing water.

If the home was built with an asphalt roof, which is the most common type of roofing material, the house is not likely to support tile or slate roofing.

A roofing company professional from Southern Home Services of Charlotte would be happy to answer questions about windows or vinyl siding.

These types of materials are much heavier than asphalt, and even if roofing materials weigh below the home's load bearing capacity, the roof will still have to support other structures. This is why most experts recommend homeowners choose a roofing material no heavier than the original components if remodeling or renovation is underway.

Standing water also has the potential to add enormous amounts of weight to a roof. If water has been on a roof for more than 48 hours, it is considered standing water. This water normally forms as a result of a depression in the roof, created by overflowing gutters or ice dams.

Water is very heavy; just 10 square feet of water an inch deep can add 500 pounds of weight to a roof. Since water is so heavy, it can cause a roof to sag. If a depression in the roof already exits, it may become larger if water continues to pool. If a large concentration of water is allowed to pool for a considerable amount of time, a leak may begin to develop.

Ice dams are walls of ice that form when melting snow freezes at the edge of a roof. These walls prevent additional melted snow from going anywhere, which can mean that there are large amounts of standing water stuck in a small area near the edge of the roof.
