As a homeowner in Barnsley, you may be wondering if it's possible to felt over old felt on a shed roof. The answer is not a simple yes or no. In this article, we'll explore the possibilities and considerations of overlaying new felt on an existing shed roof.

Roof felt, also known as underlayment, is a layer of material installed between the roof deck and the roofing material, such as shingles or tiles. Its primary function is to provide a waterproof barrier and protect the roof from damage. Over time, the old felt can deteriorate, leading to leaks and other issues.

In some cases, it's possible to felt over old felt on a shed roof. However, this approach is not always recommended. If the old felt is still in good condition, and there are no signs of damage or rot, you might be able to overlay new felt on top. But, if the old felt is damaged, rotten, or has been compromised by water, it's essential to replace it entirely.

Before attempting to felt over old felt, consider the following:

• Wood damage: If the old felt has been compromised, there's a risk of wood damage underneath. In this case, it's crucial to inspect the roof deck and replace any damaged wood before installing new felt.
• Bitumen sheets: If the old felt is a bitumen-based material, it may not be compatible with new felt. In this case, it's best to replace the old felt entirely.
• Future repairs: Overlaying new felt on old felt can make future repairs more challenging. If you need to access the roof deck or replace shingles, you'll have to navigate through multiple layers of felt.

In most cases, it's recommended to replace the old felt entirely. This approach ensures a clean and stable surface for the new felt, mitigating the risk of future damage. When replacing old felt, make sure to:

• Inspect the roof deck: Check for any signs of damage or rot and replace any affected wood.
• Install new felt: Use high-quality felt sheets, and ensure they're properly secured to the roof deck.
• Get professional help: If you're not experienced in roofing repairs, consider hiring a professional roofer in Barnsley to ensure the job is done correctly.

While it's possible to felt over old felt on a shed roof in Barnsley, it's not always the best approach. If the old felt is damaged or compromised, it's essential to replace it entirely to ensure a watertight seal and prevent future damage. If you're unsure about the best course of action, consult with a professional roofer in Barnsley for guidance.
