If you’re interested in reading our flat roof waterproofing guide, then you are likely to be concerned about potential leaks, or you may already be experiencing one. Flat roofs are often more susceptible to leaks in comparison to a sloped roof, due to pooling as water does not run off as easily. Therefore, finding the best waterproofing for flat roofs is essential.
However, there are so many products on the market now that it’s difficult to know how to choose the right one. Here at Alvadac you can find supplies for your flat roof in our shop or more advice on how to go about the job in the article below.

Finding the leak and sealing a flat roof
If water seems to drip from the same spot, it’s time to track down the source. Finding a leak can be tricky from above, so start inside. Measure from the leak on the ceiling to the nearest wall, then use the same measurement on the roof above to pinpoint the likely trouble spot.
Tips on how to inspect your flat roof
- Put safety first: Only inspect your roof if it’s completely safe. Use a secure ladder and never step onto the surface if you’re unsure about its stability. Flat roofs can be slippery, so temporary boards may be needed if there’s no anti-slip coating.
- Check after rain: Look for puddles and drainage issues after wet weather. These signs will be more visible following rainfall.
- Don’t forget the gutters: Sometimes what looks like a roof leak is actually blocked guttering. Clear out debris and make sure water can flow freely.
- Look for common signs: Check for blisters, splits, cracks or signs of ponding. If the surface resembles cracked leather or reptile skin, this could represent a common issue caused by sun exposure and moisture. Left untreated, it can get worse over time.
