Your roof needs to be in tip-top condition year-round in order to properly perform its functions, such as protecting the interiors from harsh weather elements. But if your roof is sagging or showing signs of structural distress, it is critical to act soon to save the system and keep your living space protected. Here are three possible reasons your roof is sagging to help you prevent further damage.
1. Water Damage
Roofs, in general, deal with a lot of water or melting snow. If your roof is not well-designed or improperly installed, elements like rain, snow and ice can quickly damage it, and damage to any part of your roofing structure can allow these elements to seep in and weaken the underlying components. Over time, the trapped moisture encourages the growth of mold and mildew, which further causes the roof to deteriorate and sag.
If your sagging roof is the result of water-related damage, you need to correct the problems that allowed the damage to occur in the first place. This can mean replacing your cracked or missing shingles, worn-out flashing or repairing your gutters.
2. Excess Weight
While most roofs are designed to support the additional weight of freezing precipitation during winter, a record amount of snow or ice for long periods of time can eventually cause the roof to sag. If you think that snow buildup is causing your roof to sag, call in a roof maintenance professional to clear your rooftop of heavy snowfall. It is also important to keep your attic well-insulated and sufficiently ventilated to stave off ice dams.
3. Inadequate Roof Joints and Rafters
Joints and rafters help support and frame your roofing system, carrying the load on top of your house, including the shingles, underlayment, snow, ice and more. If these components are poorly constructed or improperly installed, they can cause your roofing structure to sag and fail over time. If you believe that your roofing system is unstable, it is best to schedule a thorough inspection to determine the root cause of the problem.
