What Does A Sagging Roof Mean?

A sagging roof can be defined as a roof starting to dip down in the center or an entire house slanted. A roof that seems curved or wavy rather than straight frequently indicates a drooping issue.

Sagging is a frequent roofing problem that arises in homes with roofs that haven’t been rebuilt in a long time owing to a deteriorating structure.

What Does A Sagging Roof Indicate?

A sagging roof indicates a significant issue with the structure of your house. The problem can be minor or major and may cause structural damage to the house if left unrepaired.

Sagging occurs after a storm due to weakened beams and sagging joists caused by moisture from exposure.

What Causes A Sagging Roof?

There are different causes of a sagging roof, such as age and strength of the structure, ground movement, insufficient support of the structure, improper drainage, or a leaking roof.

1. Water Damage

Roofs see a lot of runoff over time, so it’s critical to understand how rainwater and snowmelt flow off your roof. Water has a way of discovering flaws in your roof that allow it to leak through and create water damage.

Over time, the stored moisture produces an ideal habitat for mold and mildew to thrive, further weakening and sagging your roof.

2. Too Much Weight

Michigan is well-known for its long winters filled with snow and ice. However, putting too much weight on your roof might result in structural damage.

Most roofs are built to resist the extra weight of winter precipitation. However, you should evaluate the benefits and drawbacks of eliminating part of the load if you have a snowy winter.

While using a snow rake to remove part of the snow will assist lower the burden, you run the danger of breaking off frozen, fragile shingles.

Falling ice pieces might potentially cause injury. If snow and ice removal is required, use your best judgment and consult with a professional roofing contractor.

3. Inadequate Roof Joints and Rafters

Consider your roof to be a triangle. The ceiling or roof joints are formed by the triangle’s base, while the rafters are the diagonal walls that slant toward the ridge line.

Improperly designed roof joints and rafters might lead to a drooping roof later. The weight of your roof is transmitted down via your home’s rafters, roof joints, and walls before pushing down on the ridge line.

This design is intended to securely bear the load on top of your house, including the roof, shingles, snow, and ice. However, if a residential roof is not correctly designed, it might sag with time and become structurally unsafe.

4. Age

When a roof reaches the end of its useful life, it begins to deteriorate. Roofs may easily survive more than a decade with appropriate roofing care. If you find your roof sagging, you should contact a licensed roofing specialist as soon as possible for home roof replacement.
