Have you recently checked your roof and noticed that it’s sagging? It is common for roofs to sag over time, and there are different reasons why this happens. In this post, roofing contractors from Lankford Roofing & Construction share four of these reasons.

1. Water Damage

It is important to monitor how rainwater and snowmelt drains from your roof. Improper drainage in your roof can seep water through its imperfections, causing it to sag. The trapped moisture and build up of mold and mildew weakens the roof, too. It is best to observe your roof when it’s wet. It also helps to have a licensed roofer come to your home every three years to inspect for water damage.

2. Heaviness

Your roof has its own specific limit in weight. If it carries anything above its limit over time, it may cause the roof to sag. Weight-related sagging can be caused by design flaws and heavy snowfall. 

For heavy snowfall removal, it is advisable to call roof repair contractors. Incorrect snow removal can further damage your roof. Keeping your attic insulated and ventilated helps prevent ice dams, which can cause roof leaks. There are different design flaws including undersized rafters, insufficient sheathing, or multiple layers of shingles. Make the effort to switch to lighter and more suitable roof material for your home.

3. Flawed Roof Joints and Rafters

Your roof joints and rafters are crucial to your roof’s structure. Improper construction of the joints and rafters can lead to a sagging roof later on. Always check on your roof’s joints and rafters and make sure that they are still stable.

4. Old Age

Each roof has their own lifespan. It’s important to be familiar with how much time your roof can last. Make it a habit to check on your roof’s structure and durability. With proper maintenance and care, a roof can last a decade.
