DIY Repairman Reveals: The Ultimate Guide to Fix Blistering on Flat Roofs

Well, hello there! If you're reading this, then odds are you’ve spotted some unsightly blisters bubbling up on your flat roof. But you’re not about to let that ruin your day, right? Of course not! Because you, my friend, are a dedicated DIY-er armed with the willpower and, soon, all the knowledge you need to tackle this challenge head-on.

Decoding the Blistering Mystery

Roof blisters, as they are commonly known, are areas where the roofing membrane has lost its adhesion, allowing an accumulation of air or water between the different layers. They can range from small, pea-sized bumps to large, eye-catching blemishes that tempt you to poke them. However, refrain! Puncturing these blisters can lead to leaks, and trust me, no one wants to deal with water damage.

When Should You Repair Roof Blisters?

While it may seem logical to leap into action as soon as you spot a blister, that's not always the best course of action. Tiny, benign blisters that aren't growing or near the joints/seams of your roof can often be left alone. It's the big, naughty blisters – particularly those close to joints or seams – that need a stern talking-to... or rather, some serious DIY action!

Exposing the Blister: Preparation Steps

Before we grab our repair kits, ensure your rooftop is safe to walk on. Got that? Safety first, always! Now, carry along a utility knife, roofing cement, roofing nails, a hammer, and roofing fabric. Ready? Up we go!

Step 1: Evaluating the Blister

Firstly, analyze the blister. If it's firm and there are no signs of water or damage, it’s best to leave it alone. But a spongy blister that moves under pressure? Ah, that’s a culprit. Make sure it’s dry, and we’ll get onto the next step.

Step 2: Slicing the Blister

Cut an X shape on the blister but be careful not to cut too deep! You don’t want to harm your roof deck underneath. Lift the four flaps you’ve just created, and swing by for the next step.

Step 3: Removing Moisture and Debris

Clean out the opened blister. Remove any debris or moisture potentially causing the blister. Give it some time to dry before moving onto the next step.

Step 4: Applying Roofing Cement

Now it's time for some DIY magic. Slather a generous helping of roofing cement under the flaps. Remember, more is better in this scenario.

Step 5: Press Down the Flaps

Press the flaps back down firmly. Ensure they're well adhered and smooth out any bubbles.

Step 6: Cover with Roofing Fabric

Take your piece of roofing fabric, ensuring it’s large enough to cover the blister, and press it onto the wet cement.

Step 7: One More Layer of Cement

Yes, more cement! Spread another layer over the fabric. Make sure it’s fully integrated. You’re doing great!

Final Touches: Nail Down

For good measure, hammer down a few roofing nails around the edge of the repair. And voila! Give yourself a pat on your back, you’ve successfully banished that blister.
