Why is My Roof Sagging?

Do you have a saggy
roof?

Roof sagging is one of the most common complaints from
homeowners about their roofs. A sagging roofline – shingles or other roofing
materials that appear to “bow” or “bend” at various points on the roof – can
indicate many different things.

If your roof is sagging, it’s imperative you speak with a professional
roofer in your area
immediately. Sagging roofs aren’t always
structurally deficient but they can lead to much larger problems down the line if
not addressed quickly.

Here’s what you need to know about why your roof is sagging.

What Causes a Sagging Roof?

Almost all roof sags are caused by undue pressure on the foundational
structure of the roof. Roof framing typically consists of two or more ceiling
rafters joined together mid-roof to create a house-long span. When weight
accumulates on the roof (from snow, moisture, or debris), it exerts unusual
pressure on the roof, pushing the sides of the entire building out. Even when
the force is slight, the underlying roofing components can be affected.

In some cases, roof sagging isn’t structural at all. Rotten
or saturated sheathing can also cause the roof line to sag. This can happen
when the sheathing wasn’t installed properly in the first place, or when the
roof hasn’t been consistently maintained. If water is allowed to penetrate a
roof, the plywood underneath it can warp, skewing the alignment of the
shingles.

How to Fix a Sagging Roof

In most cases, roofs suffering from significant sagging should
be replaced completely
. Without replacement, these roofs can become
unstable over time and allow moisture to creep in. Although a whole roof
replacement is certainly an investment, it pales in comparison to the cost of
repair if your interior is damaged by gushing water or strong winds.

For situations in which the problem is the roof sheathing,
not the structural components themselves, it’s possible to remove the shingles
down to the existing roof deck. From there, the sheathing is completely
replaced and new shingles are laid on top.
