What’s Causing the Roof to Sag & How Do I Fix It?

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

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

Water Damage Could Be The Culprit for A Sagging Roof

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, but it will also eventually cause parts to sag.

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

Extra Weight on the Roof Can Cause it to Sag

Your roof may not be built to handle additional weight on its surface, whether it’s something naturally occurring 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 roofing company 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.

The Age of Your Roof is a Factor When it Comes to Sagging

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 10 to 30 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.

Poor Quality Roofing Materials Can Lead to Premature Sagging

Although less common, poor quality roofing materials or subpar installation services can lead to premature slumping of your roof. A poorly installed roof can make it more prone to water damage and cause it to deteriorate faster. 

Other Factors That Can Cause a Saggy Roof

Sometimes the problem isn’t your roof at all. If your foundation has shifted in any way, your walls and your roof might have shifted along with it which can be very problematic. This will require a consultation with a construction professional to figure out the best plan to move forward to fix your foundation damage. 

Is a Sagging Roof Dangerous?

A sagging roof is potentially dangerous for your home and your family. It’s a sign that the structural integrity of your home is compromised. As more time passes, the potential for a sagging roof to collapse increases. If your roof is sagging, you want to take action as soon as possible.
