A leaking flat roof can be frustrating, but the good news is, most small leaks are fixable without calling in a pro right away. First, locate the source of the leak—it’s not always right above the damp spot inside. Check for cracks, blisters, or areas where the roofing material has lifted, especially around seams or roof penetrations like vents and skylights.
Once you’ve found the trouble spot, clean the area thoroughly—remove any debris, dirt, or standing water. Let it dry completely, because sealants won’t stick to damp surfaces. For minor cracks or holes, you can use a roof repair compound or bitumen patch. Spread it evenly over the damaged area with a putty knife, pressing it into the material. For larger leaks, you may need to apply a patch of roofing fabric over the sealant, then cover it with another layer to make it watertight.
After the repair, check your roof for proper drainage. Flat roofs aren’t perfectly flat—they should have a slight slope to guide water to drains or gutters. Standing water is a sign that you may need to improve the slope or clean out drainage channels.
If leaks keep coming back, it could be time to call a professional roofer. Sometimes, what looks like a small issue is really a sign that your roof’s waterproof membrane needs replacement.
