At A1 Roofing Reading, we often receive questions from homeowners and property managers in Reading and the surrounding areas about the waterproofing capabilities of roofing felt. In this article, we will explore the properties of roofing felt, its uses, and whether it is truly waterproof.

Roofing 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 purpose is to provide an additional layer of protection against water infiltration and to help prevent damage to the roof deck.

Roofing felt is typically made from a combination of natural and synthetic materials, such as asphalt, fiberglass, and polyester. It is designed to be durable, flexible, and resistant to water penetration. However, it is not entirely waterproof.

While roofing felt is resistant to water penetration, it is not a substitute for proper waterproofing measures. In fact, most roofing felts are designed to be breathable, allowing moisture to escape from the roof deck. This helps to prevent the buildup of condensation and reduces the risk of water damage.

Roofing felt is not a foolproof solution for waterproofing. It can be damaged by:

• Prolonged exposure to water
• UV radiation
• Foot traffic
• Extreme temperatures

Roofing felt is a useful material for:

• Providing an additional layer of protection against water infiltration
• Helping to prevent damage to the roof deck
• Reducing the risk of condensation buildup

If you are looking for a more robust waterproofing solution, you may want to consider:

• EPDM rubber roofing
• PVC roofing
• Asphalt shingles with built-in waterproofing membranes

While roofing felt is a useful material for providing an additional layer of protection against water infiltration, it is not entirely waterproof. At A1 Roofing Reading, we recommend using roofing felt in conjunction with other waterproofing measures to ensure the integrity of your roof.
