Beneficial characteristics of Roofing Paper

Resistant to Water:

Roof felt is well-known for its water-repellency. It assists in the drainage of rainwater, preventing it from overflowing into your home. 

Weather Protection: 

Having Roofing paper beneath the tiles adds an extra layer of protection, just like a second line of defense system. As a result, snow and wind-driven rain do not create moisture damage, rot, leaks or  mould.

Fire Resistance:

Typically, tiles alone are not able to exceed fire resistance requirements. Your home’s fire resistance significantly improves when the roofing paper is placed. 

Roofing paper on exterior walls

Roof paper is commonly used as a water-resistant layer between the wall sheathing and the wall covering by the builders. This layer prevents moisture from penetrating the interior of the house. As a result, roofing paper can help to keep underlying materials from decaying. 

Roofing paper on Interior walls

Roofing paper is also commonly used on interior walls, especially below plaster. Plaster is applied directly to wood breaks over time as the wood expands and contracts.

Roofing felt does not expand or contract, therefore it acts as a slip plane and offers a stable surface for the plaster.

Roof felt also stops water vapors trapped by the plaster from leaking into the water-resistant wood. Felt isolates the wood from the plaster, allowing the plaster to absorb and release moisture without damaging the inner wall structure.

Roofing paper can be used on both your internal and external walls. It provides additional protection and durability to the walls, similar to your roof.

But make sure to choose the roofing paper that is approved and suitable for the tiles above them, as well as those that meet building requirements.
