If your roof parapet is damaged in any way, it can lead to serious problems for your building. In this post, we will discuss seven signs that you need roof parapet repair. Don’t let these problems escalate – contact a professional today!

What Is Parapet Roofing?

A ‘parapet wall’ is a structure built on top of a roof to protect the roof edges and provide additional security. It is usually made from concrete, stone, or brick, and it can be either solid or hollow.

Where extending above a roof, a parapet may simply be the portion of an exterior wall above the roof surface. However, it is often also fitted with a railing or balustrade to prevent people and objects from falling off.

Even on flat roof systems, a parapet is often installed to provide these same benefits and functions. Parapets can also hide unsightly roofing material and equipment from view. In addition, the exterior walls will have a similar appearance to the parapet, making it a more aesthetic choice for some property owners.

They may also mark the boundary between two properties or act as a decorative feature. Parapet roofs are commonly found on flat roofs, where they serve to prevent water from flowing off the roof and onto the ground below.

7 Signs You Need Roof Parapet Repair

If you have a parapet roof, it is crucial to be aware of the signs that you may need repair work carried out. Some of the most common signs include:

1. Leakage

One chief sign that your parapet roof needs repairing is if you start to notice leakage. This could be in the form of water seeping through cracks in the wall or pooling on the surface.

It is important to act quickly if you spot any signs of leakage as it can cause serious damage to both the parapet and the roof itself if left untreated.

If you are unsure whether the leakage is coming from the parapet or with the roof membrane, it is best to get a professional opinion. They will be able to assess the situation and advise you on the best course of action.

Quick Tip: Check your gutters and downpipes regularly to ensure they are clear of any debris. This will help to reduce the risk of water leakage.

2. Missing Coverings

If you notice sunlight shining through cracks in your parapet walls, it means that the wall coverings are no longer intact. Many years of exposure to the elements can cause the coverings to break down and deteriorate. If left unrepaired, water will eventually seep through the cracks and cause further damage to your parapet walls.

If you see any missing coverings on your parapet walls, it’s important to have them repaired as soon as possible. Otherwise, you’ll be at risk for water damage and other problems.

3. Cracks Or Fallen Concrete

Improper waterproofing or a lack of drainage can cause the parapet walls to crack and eventually fall. This is a serious problem because it can create openings for water to enter your building. If you see cracks in your parapet walls, you should have them repaired as soon as possible.

If you see any fallen concrete, it’s important to clean it up right away. Fallen concrete can create trip hazards, and it can also damage your roof.

4. Bulging Or Sagging Walls

If your parapet walls are bulging or sagging, it’s a sign that they’re not properly supported. This can be caused by a number of factors, including poor construction, settlement, and soil erosion. If you see any bulges or sag in your parapet walls, you should have them inspected by a professional as soon as possible.

Settlement is a common cause of bulging or sagging parapet walls. When the soil beneath your foundation settles, it can put pressure on the walls and cause them to bulge or sag. This is usually a slow process, so you may not notice it until the problem has become severe.

5. Debris buildup

Debris buildup is another sign you may need roof parapet repair. If leaves, sticks, or other debris accumulate on the roof parapet, it can create a dam that will hold water against the wall. This can cause damage to your wall and even lead to water infiltration.

On a metal roof, debris can also cause rust and corrosion. Therefore, it’s important to keep the roof parapet clear of debris so that water can flow freely off the roof.

6. Mold and Mildew

When water gets into your roof plane, it can create an environment perfect for mold and mildew to grow. This can cause a number of health problems, so it’s important to address any signs of mold or mildew as soon as possible.
If you notice any black spots on your walls or ceilings, this could be a sign of mold. Additionally, if you smell a musty odor in your home, this is also often a sign of mold.

7. Excessive Water Runoff

An improperly functioning roof parapet can lead to excessive water runoff, which can damage the roof decking and sheathing and the interior of your home.

If you notice that your roof is constantly leaking or that there is a lot of standing water on your property after it rains, then you may need roof parapet repair.

How to Repair a Roof Parapet

One of the best ways to prevent roof parapet problems from escalating is to have regular maintenance and repairs performed by a professional. If you notice any of the signs mentioned in this article, it’s important to have the problem assessed and repaired as soon as possible.
