Signs That Your Roof Needs Waterproofing

Updated: Jul 27, 2021

Unless you plan to keep water buckets at most parts of your house every time it rains, you want to ensure that your roof doesn't need any waterproofing services.

The most critical step during the whole roof installation process is the waterproofing of your roof. If you or your construction contractor fails to ensure that, you will not only be facing a hassle with the furniture, but the top will also weaken as water will keep seeping through it. Furthermore, your property's value will also drastically decrease with such issues.


Roof waterproofing is a different form of defense applied to your roof to ensure that no water enters your property and causes decay in the walls or support beams. Roof leaks can be caused by various factors, the most common of which is poor waterproofing services from your contractor.


The most obvious sign that you need waterproofing services is traces of water that leaked through your roof. However, if you want to be sure that you live under a waterproof roof, you should always look for some less obvious problematic signs. We are listing some of such characters below:

  • Unusual dampness: Even if you don't see water dripping into your home, it could be seeping into your roof area. Look for damp patches on your roof's timbers and at every one of your roof's corners.

  • Tiny holes: Light is another telltale symptom of poor waterproofing. Take a peek around your roof area (the attic in most cases) when the weather is lovely and bright outside, but don't turn on the lights. If you can see light beams streaming through a window into a dark room, your roof isn't watertight. After all, where there's a hole for light, there's also a hole for water.

  • Mold Growth: Mould can grow in wet environments over time. If you notice mold in your roof, it's a sign that water is coming in. Ensure to have this checked out by a specialist.


People usually believe that shingles and tiles on their roofs can assure them of waterproofing. However, it's not like that. Depending on the materials the roofing contractors use, and how old your roof is, your tiles can have enough cracks to let water in. To learn more about asphalt shingles, click here.
