What’s Causing the Roof to Sag?

Sagging roofs are a fairly common thing for many residential properties and even some commercial roofing systems. It’s easy to pin the blame on one event, but in truth, the reason why your roof is showing signs of distress is not always that obvious from the curb.

What’s Causing the Roof to Sag?

In this post, Berry Roofing & Solar shares what causes roofs to sag and what you can do about it.

Water Damage

Your roof deals with a lot of runoff and the rainwater may eventually find its way into cracks and other imperfections. This will eventually cause water damage as it spreads deeper into the roof. Additionally, the trapped moisture creates a suitable environment for mold and mildew. Not only does it further weaken your roof, it will eventually cause parts to sag.

Fortunately, you can prevent this from doing regular roof inspections and being more proactive when it comes to roof repair work. The latter helps you address potential problems when they are still smaller and easier to handle.

Extra Weight on the Roof

Your roof may not be built to handle additional weight on its surface, whether it’s something naturally occuring like packed snow or your own addition like a solar panel grid. Once the weight threshold is reached, the roof will weaken and begin to sag.

To avoid this, always keep the roof clean of any debris. Additionally, you’ll want to consult your local roofer if you’re planning on installing things like solar tubes and photovoltaic grids. That way, you can have a better idea if your roof can handle the extra weight of the systems.

Old Age

Finally, sagging occurs as a consequence of roof aging and long-term wear and tear. For asphalt roofs, deterioration starts near the end of its approximate service life of 20 to 24 years. If this is the case, sagging itself is less of a problem and more of a sign that you need to replace your roof soon.
