What Professional Skylight Waterproofing Really Involves in Johannesburg
Skylights brighten a home, but they also introduce one of the most common weak points in a roof. Because a skylight interrupts the natural flow of tiles, sheets, or waterproofing systems, even the smallest gap can allow water to enter. In Johannesburg, where storms arrive suddenly and UV exposure is intense, skylight seals deteriorate much faster than most homeowners realise.
Proper skylight waterproofing requires full attention to every connection point, not just a quick silicone patch. We focus on sealing the frame, strengthening the flashing, and reinforcing the joints where the roof surface meets the skylight housing. This ensures the roof remains watertight without affecting the skylight’s appearance. In many cases, especially where surrounding surfaces are damaged, skylights need support from nearby crack and blister repairs to prevent water tracking beneath old coatings.
Why Our Skylight Waterproofing Approach Works
Skylights leak for two main reasons: poor sealing during installation or materials that have degraded over time. Our approach stops both issues by combining flexible waterproofing systems with durable UV-resistant finishes.
We reseal all joints, reinforce flashing, and install coatings designed to move with the structure rather than crack under heat. This prevents leaks that commonly appear during Johannesburg’s heavy storms and extends the life of both the skylight and the surrounding roof. When skylights are installed on metal roofs, we often pair this with professional rust treatment for metal roofs to secure screws, overlaps, and sheet joints that commonly fail.
Who This Service Is Ideal For
Our skylight waterproofing service is designed for homes with leaking areas around skylights, older units with worn seals, and properties where incorrect installation created ongoing issues. Skylights on tiled, metal, and concrete slab roofs all require tailored sealing methods to ensure long-term protection in Johannesburg’s climate.
Problems We Solve Before They Cause Internal Damage
Skylight leaks can cause ceiling damage, mould, and wood rot if not repaired early. We treat gaps around skylight frames, weakened flashing, failed silicone, and moisture channels that form behind old waterproofing. Many of these hidden defects only reveal themselves during storms, which is why proper sealing is essential.
Benefits and Outcomes You Can Expect
Once your skylight is waterproofed correctly, you can expect a clean, watertight seal that lasts through storms, reinforced flashing, and long-term protection against UV damage. This also prevents the internal damp and staining commonly caused by incorrectly sealed skylights.
How Our Skylight Waterproofing Process Works
Our process includes inspection, removal of worn sealants, reinforcement of flashing, application of liquid rubber or acrylic waterproofing, and UV-resistant top coatings. If the skylight leak is part of a larger roof problem, we may recommend complementary roof leak repairs to ensure all entry points are addressed properly.
Common Questions About Skylight Waterproofing
Heavy storms push water into weak flashing joints, which is why many skylights only leak during strong rainfall. We waterproof skylights on all roof types, and in most cases, sealing can be done without replacing the skylight itself. All waterproofing is applied neatly to blend with the roof.
Take the Next Step
If your skylight is leaking or showing signs of wear, now is the right time to secure it before the next storm. Contact us to book a roof assessment, and we will recommend the best long-term waterproofing solution for your skylight.
