All roofs have a specific load bearing capacity, which determines how much weight the roof can safely support. Roofs' load bearing capacity is generally determined by a combination of the structural elements of the home and the strength of support structures such as rafters and joists. It is important that the weight on a roof does not exceed what it can support, or it may lead to a collapse.

There are a several potential scenarios that cause Madison roofing to become overburdened. The most common source of overburdening is the presence of standing water. However, a roof may also become overloaded if homeowners install too many things on it, such as satellites or solar panels, and installing a roof with material that is heavier than the home was built with may also put too much weight on a roof.

Standing water is one of the most common sources of trouble because water is very heavy, and it can develop due to a number of causes. One square foot of water an inch deep weighs five pounds, and an inch of water over a 10-foot-by-10-foot square area weighs 500 pounds. It doesn't take an enormous amount of water to start causing problems.

In the winter, standing water is most likely to develop due to ice dams. When a home doesn't have enough insulation or if it isn't the correct R-value, the attic may radiate heat.

This can cause snow to melt and flow down the roof. When it meets freezing air again, usually at the edge of the roof, it will freeze into icicles, which are also referred to as ice dams.

Ice dams create a wall of ice that prevents any other melted snow from going anywhere. Increasing amounts of water may gather on the edge of a roof behind the dam, which can create a depression in the roof, causing a collapse.

In the summer, heavy rains may cause gutters to overflow, especially if gutters are clogged or have blockages. This water may create depressions in the roof, which means that water will have a place to collect, even if the gutters flow properly later.

Due to how much the water weighs, even in small amounts, these depressions will frequently get larger, and the weight of water can cause the roof to sag even more. Along with depressions formed by the weight of the roof's gutters, there may also be areas in a roof that are uneven. This can be due to a roof settling or improper installation, but they also are areas where water may collect and add weight to the roof.
