A1 Roofing Preston

As a homeowner in Blackpool, Lancashire, you may be wondering if it's possible to felt over old felt on a shed roof. At A1 Roofing Preston, we've encountered this question numerous times, and our expert roofers are here to provide you with the answer.

Felt roofs are a popular choice for sheds and other flat-roofed structures in the UK. They're relatively inexpensive, easy to install, and provide a waterproof layer to protect the underlying timbers. However, over time, the felt can deteriorate, leading to leaks and damage to the roof.

While it's technically possible to felt over old felt, it's not always the recommended approach. In fact, our experienced roofers would advise against it in most cases. Here's why:

• Condition of the Old Felt: If the old felt is in poor condition, it may be difficult to ensure a secure bond between the old and new layers. This can lead to a weakened roof structure and increased risk of leaks.
• Wood Condition: If the underlying timbers are rotten or damaged, applying new felt over old felt won't address the underlying issue. In fact, it may even make the problem worse.
• Adhesive Issues: The adhesive used to secure the new felt may not bond properly with the old felt, leading to a weak and potentially leaky roof.

So, what's the recommended approach? Our expert roofers would suggest the following:

• Conduct a Roof Survey: Before making any decisions, it's essential to conduct a thorough roof survey to assess the condition of the old felt, underlying timbers, and the overall roof structure.
• Remove Old Felt: If the old felt is in poor condition, it's best to remove it entirely and inspect the underlying timbers. This will ensure that any damaged or rotten wood is replaced before applying new felt.
• Apply New Underlay: Once the old felt is removed, our roofers will apply a new underlay to provide a smooth, even surface for the new felt.
• Install New Felt: Finally, we'll install a new layer of high-quality felt, ensuring a secure bond and a watertight seal.

In some cases, it may be possible to overlay the old felt with a new layer, but this should only be done if the old felt is in good condition and the underlying timbers are sound. Our expert roofers will assess the roof and determine the best course of action.
