Common Signs Of A Failing Roof

Posted on: 7 September 2018

If you want to protect the interior of your home, having a sound roof is essential. A roof that is in good repair will keep moisture and the elements outside and protect the structural integrity of the entire house. Unfortunately, roofs do not last forever, and eventually your roof will need to be replaced. If you want to avoid large repair bills and major damage to your home, it is important to know when your roof is failing so you can make arrangements to have it replaced. Some of the most common signs of a failing residential roof include:

Missing Shingles

For a roof to properly protect the interior of a home, all shingles must be intact. Over time, as the shingles age, they can become loose or fall off. It is also possible for a strong storm to blow shingles off of a roof. If your roof is missing just a couple shingles, you can hire a roofing contractor to replace them. But when there are multiple sections of your roof that are missing shingles or have very loose shingles, it typically means that the roof is failing.


When you own a home, it is always a good idea to visually inspect your roof. If you're standing on the ground and can notice that a section of the roof is sagging or has buckled, you need to take action quickly. A sagging or buckling roof is not structurally sound, and depending on the cause of the sagging, the roof could potentially collapse. In the event that your roof is sagging, you need to contact a roofing contractor as soon as possible.

Stains on the Ceiling

Water stains on your ceiling should always be taken seriously. When water stains are present, it means that a substantial amount of water is leaking through your roof, into the attic, and then on to your ceiling. Failure to take action can cause a lot of damage to your home and cost a lot of money to repair. While small roof leaks can often be repaired, major roof leaks, or multiple roof leaks, are often a sign that the roof is failing and is at the end of its lifespan.

Mold or Algae Growth

A small patch of mold or algae can be removed from a roof. But, when a large portion of your roof is experiencing mold or algae growth, it means that there is an issue with the roof, and excess moisture is getting trapped between the shingles and the roof decking. This moisture can quickly damage the roof shingles, so large areas of mold or algae often mean that you need to make plans to replace your current roof.
