I just purchased an older home with a flat roof that's had some minor leaks—about 12' x 14' in size. While I plan to fully replace the roof down the line, I'm hoping to make some temporary fixes to extend its lifespan for a few years. Do you have any recommendations for DIY patching or sealing methods, like using a rubber membrane or similar solutions? The leaks drip slowly during heavy rain, and it seems to be coming from the flat part, not the pitched areas. I'd appreciate any tips or product suggestions you might have!

Gaco roof sealant works wonders and lasts for a couple of years—it’s super easy to apply too! You should definitely check it out.
I swear by the silicone roll-on material from ABC Supply! I used it on an old flat roof, and it gave me about seven years without needing any maintenance, even under the tough Florida sun. It's a couple hundred bucks for a 5-gallon bucket, but totally worth it.
Try using Henry elastomeric roof coating; it’s pretty easy to apply. Just keep in mind that if the leak’s under tiles, it might not solve your problem completely.
You might want to consider spray foam, which is often used for commercial flat roofs. It's a solid option for those looking to patch things up on a budget.
