How to repair roof felt from inside loft? Roof felt plays a crucial role in protecting your home from the elements, acting as a barrier against water and wind. Over time, however, roof felt can wear down or become damaged, leading to leaks and other issues.

If you’ve noticed signs of damage in your loft, you might be wondering how to fix it without getting on the roof. Fortunately, it’s possible to repair roof felt from inside the loft, and I’m here to guide you through the process step by step.

What is Roof Felt and Why is it Important?

Roof felt, also known as underlayment or tar paper, is a layer of material that sits between your roof’s structural elements and the external roofing material, like tiles or shingles. Its primary function is to provide an extra layer of waterproofing, protecting your home from water infiltration. Roof felt also helps to protect against wind-driven rain and contributes to the overall durability of your roof.

When roof felt becomes damaged, it can compromise the integrity of your roof, leading to leaks, dampness, and even structural damage if left unaddressed. That’s why it’s essential to keep an eye on the condition of your roof felt and repair any issues as soon as they arise.

What are the Signs to Find that Your Roof Felt Needs Repair?

Before diving into the repair process, it’s important to identify whether your roof felt is indeed in need of repair. Here are 4 common signs to look out for:

• Water Stains on the Ceiling: If you notice water stains or discolouration on the ceiling inside your home, it could be a sign of a roof felt issue.
• Dampness in the Loft: Damp or musty smells in your loft might indicate that water is seeping through damaged roof felt.
• Visible Tears or Gaps: During a loft inspection, check for any visible tears, gaps, or holes in the roof felt.
• Dripping Water: If you see water dripping inside the loft during or after rain, it’s likely that your roof felt has been compromised.

If you notice any of these signs, it’s time to take action and repair the roof felt before the problem worsens.

What are the Tools and Materials Needed for Repairing Roof Felt from Inside the Loft?

Before you begin the repair, you’ll need to gather a few essential tools and materials. Here’s what you’ll need:

• Utility Knife: For cutting the roof felt and the patch material to size.
• Roofing Adhesive or Sealant: To securely attach the patch to the damaged area.
• Roof Felt Patch: You can purchase a small roll of roof felt or use a patch kit specifically designed for repairs.

What are the Step-by-Step Guide to Repair Roof Felt from Inside the Loft?

Now that you’re equipped with the necessary tools, let’s get started with the repair.

Step 1: Locate the Damaged Area

The first step is to locate the exact spot where the roof felt is damaged. This might be obvious if you can see a tear or hole, but if not, look for signs of water ingress, such as damp patches, drips, or water stains. Once you’ve found the damaged area, you’re ready to begin the repair.

Step 2: Prepare the Area for Repair

Before you apply any patches, it’s important to prepare the area properly:

• Clear the Area: Remove any insulation or debris around the damaged area to ensure you have a clear workspace.
• Dry the Area: If the area is wet, use a cloth or towel to dry it out as much as possible. Roofing adhesive works best on dry surfaces.
• Cut Away Damaged Felt: Use your utility knife to carefully cut away any loose or severely damaged sections of felt. This will give you a clean surface to work on.

Step 3: Cut and Apply the Felt Patch

Next, you’ll need to cut a piece of roof felt that’s large enough to cover the damaged area with a bit of overlap:

• Measure the Area: Use your tape measure to determine the size of the patch needed. It should be slightly larger than the damaged area to ensure full coverage.
• Cut the Patch: Cut a piece of roof felt to the required size using your utility knife.
• Apply Roofing Adhesive: Apply a generous amount of roofing adhesive around the edges of the damaged area and on the underside of the patch.
• Position the Patch: Carefully position the patch over the damaged area, pressing it firmly into place.

Step 4: Secure the Edges and Seal the Patch

To ensure the patch holds and remains waterproof:

• Seal the Edges: Apply additional roofing adhesive around the edges of the patch, pressing it down firmly to ensure a good seal.
• Smooth Out the Patch: Use your hands or a flat tool to smooth out any wrinkles or air bubbles in the patch, ensuring it adheres properly to the roof felt.

Step 5: Inspect and Test the Repair

After completing the patch, it’s important to inspect your work:

• Check the Patch: Make sure the patch is securely attached with no gaps or loose edges.
• Test for Leaks: The next time it rains, check the loft to ensure no water is getting through the repair. You can also simulate rain by spraying water onto the roof from the outside and checking for leaks inside.

What are the Alternative Methods for Repairing Roof Felt?

If the standard patch method doesn’t work for your situation, here are a few alternative methods:

What are Temporary Fixes?

If you’re not able to make a permanent repair right away, you can use a temporary fix to stop water ingress. A tarpaulin or heavy-duty plastic sheet can be secured over the damaged area as a temporary barrier.

How to Use Roofing Tape?

Roofing tape is a quick and easy option for small tears or cracks. It’s self-adhesive and can be applied directly over the damaged area to create a waterproof seal. This method works best for minor repairs.

When to Call a Professional?

If the damage is extensive or if you’re not confident in your ability to repair it yourself, it might be best to call a professional roofer. They can assess the situation and make the necessary repairs safely and effectively.

What are the Safety Tips for Working in the Loft?

Working in the loft can be tricky, so it’s important to follow some basic safety precautions:

• Ensure Proper Ventilation: Make sure the loft is well-ventilated, especially if you’re using adhesives or sealants.
• Use Adequate Lighting: Ensure you have enough light to see clearly while you work. A headlamp or portable light can be helpful.
• Watch Your Step: Be mindful of where you step to avoid damaging insulation or losing your balance.
• Wear Protective Gear: Always wear gloves, safety glasses, and a dust mask to protect yourself from dust and debris.

What are the Common Mistakes to Avoid When Repairing Roof Felt?

Even with the best intentions, mistakes can happen. Top 3 pitfalls to avoid:

Improper Patch Application

Applying the patch incorrectly can lead to leaks and further damage. Ensure the patch is large enough and fully sealed around the edges to prevent water from getting in.

Ignoring Small Leaks

Small leaks might seem insignificant, but they can lead to bigger problems if not addressed. Always take the time to repair even minor damage to prevent it from worsening.

Using Inappropriate Materials

It’s tempting to use whatever materials you have on hand, but it’s important to use the right materials for roof felt repairs. This ensures the repair is durable and effective.
