Leaky Roof Here’s How to Fix It Fast Before It Gets Worse

How to Fix a Leaky Roof Fast | Quick DIY Tips & Best GRP Repair Kits

When the wind is gusting and rain is pouring down, the last thing you want is a drip from your roof. If you’re wondering how to fix a leaky roof fast, don’t wait — the sooner you act, the less damage you’ll face. Here’s how to take control.

Stay Safe and Do a Quick Check

Before climbing up, stop and protect yourself. Use non-slip shoes, and if it’s windy or stormy, stay off the roof. Instead:

  1. Go into the attic or underneath the leak and find the spot where moisture is getting in.

  2. Watch for dark stains, damp spots, or gaps around the roof tiles, flashing (the metal strip between the roof and wall), or seams.

  3. If any part of the structure looks weak or dangerous, skip the DIY and get a professional.

How to Fix It Yourself

If it’s a small leak and you’re comfortable working safely, you can try a fix yourself. Follow these simple steps.

A. Clear the area

Remove leaves, moss, grit, or anything blocking drainage. Clean the surface so it’s smooth and dry, even a small bit of moisture under a patch can stop it bonding properly.

B. Apply the right product

Here are some reliable options from Apex to help you:

  1. Use the Apex Fibreglass Economy Roofing Kit for a full flat roof repair – it includes resin, matting, and topcoat.

  2. For smaller sections or patchwork, use the Apex General Fibreglass Repair Kits.

  3. If you already have the matting but just need to seal cracks or worn areas, go for the Apex 10 kg Roofing Resin.

Follow these steps carefully:

  1. Mix the resin and hardener well.
  2. Lay the matting down smoothly.
  3. Apply the topcoat.
  4. Let it cure completely before testing.

C. Monitor and maintain

After you’ve completed the DIY fix, let it dry and then observe it during the next rainfall. If you still see dampness or new leaking, it might be time to hire a pro.

How to Find a Good Contractor

If the damage is big, you feel uncertain, or you’d rather leave it to experts, choosing the right contractor matters. Here’s what to check:

  1. Ask for proof of insurance and ask how long they’ve been working with flat/GRP-type roofs.

  2. Get at least two quotes. Make sure they cover the same scope-materials, labor, weatherproofing, and guarantee.

  3. Check for past projects or reviews. Apex provides easy and affordable fibreglass roofing supplies, kits, and GRP flat roofing. They also offer accessories, next-day delivery, and free advice on fibreglass products.”

  4. Clarify the timetable. Because if winter is coming and the leak is still there, you don’t want to wait.

  5. Ensure you get a written guarantee: how long the repair is covered and what happens if it fails.

Renting a Flat? How to Convince Your Landlord

Living in a rented property and spotting a leaking roof? You have rights, and you can act. Here’s a simple approach:

  1. Take photographs of the leak, damp patches, and any visible damage.

  2. Write your landlord or letting agent a short, clear message saying the roof leak is urgent because damp can cause mold, structural damage, and health issues.

  3. Look at the tenancy agreement: it usually says the landlord must ensure the building is safe and weather-tight.

  4. I can help you get a quote if you'd like. However, I want to stress that I expect the repair to be free. This is due to it being part of the building’s structure.

  5. Keep all communication in writing (email or message) so you have a record. Landlords generally prefer to fix issues rather than deal with bigger bills later.
