An aesthetically-pleasing roofing system has sturdy framing that allows for straight lines on all angles. Over time, however, you might notice some signs of distress, including sagging in some spots. While it doesn’t necessarily mean that your roof is on the verge of collapse, this issue is something that needs to be addressed immediately. A contractor that specializes in residential and commercial roofing can determine its exact cause and carry out the necessary fixes.
Here’s a look at the various causes of sagging in residential roofing systems.
Poor Construction of the Roof’s Support Structure
A sloped roof is supported by the joints forming the ceiling and the rafters slanting toward the ridgeline. An improperly constructed support structure will eventually sag and become unstable.
Excessive Load
The design of residential roofing systems allows them to withstand the added weight of winter precipitation. Too much snow or ice buildup, however, could lead to structural damage. Removing snow with a rake is possible to lighten the load, but it has its drawbacks. For one, some of the shingles that are already brittle might break off. Also, chunks of falling ice can pose a hazard.
Water Damage
A sloped roof deals with water runoff every time it rains and snows, which is why checking how precipitation drains from its surface is imperative. Imperfections allow moisture to seep in and damage the roof’s inner layers and support structure. It can lead to mold and mildew growth, as well as rot that can weaken the wooden components. Getting your roof inspected at least once a year allows you to keep track of its structural integrity.
