What is a Breathable Roof Membrane?

A breathable roof membrane is an advanced barrier designed to allow moisture vapour to escape from within a structure while preventing water infiltration from the outside. This dual functionality is essential for managing condensation and moisture, which can lead to problems like mould growth and structural damage over time. Typically manufactured from high-quality, durable synthetic materials, breathable membranes help maintain a healthy indoor environment while protecting roofing structures from the elements.

What is Roofing Felt?

Roofing felt, also known as tar paper or felt paper, is a traditional roofing material often used to provide an additional layer of protection beneath shingles, tiles, or metal roofing. It is typically made from a combination of natural and synthetic fibres, saturated with asphalt or other waterproofing materials. Roofing felt adds an impervious layer to the roofing system, acting as a barrier against wind-driven rain, snow, and ice.

The Perfect Duo: Breathable Roof Membrane and Roofing Felt

1. Comprehensive Moisture Management

When used in conjunction, breathable roof membranes and roofing felt offer comprehensive moisture management. The breathable membrane allows excess moisture and vapour to escape from the interior of the building, preventing condensation buildup and subsequent damage. At the same time, roofing felt acts as a waterproof barrier, protecting the roofing system from external moisture. This synergy creates an effective moisture control system that prolongs the life of the roof and keeps the interior environment comfortable and healthy.

2. Excellent Weather Protection

Combining these materials ensures that homes and buildings can withstand harsh weather conditions. Roofing felt provides a robust layer of resistance against wind and rain, while the breathable membrane helps regulate humidity levels, reducing the possibility of leaks or damage associated with trapped moisture. This dual layer of defense is crucial for protecting vulnerable roofing structures, particularly in regions prone to severe weather.

3. Enhanced Energy Efficiency

Both breathable membranes and roofing felt contribute to improved energy efficiency within buildings. By managing moisture levels and regulating indoor temperatures, these materials can help reduce reliance on heating and cooling systems. This can lead to lower energy bills and a reduced carbon footprint—benefits that are increasingly important to environmentally conscious homeowners and builders.

4. Versatility Across Roof Types

The combination of a breathable roof membrane and roofing felt can be utilized effectively across various roofing types, from pitched roofs to flat and low-slope roofs. This versatility allows builders to optimise weather protection, moisture control, and overall roof performance, regardless of the roofing structure.

5. Ease of Installation

While both materials are lightweight and flexible, making installation efficient, their combined use streamlines the roofing system setup. Once the roofing felt is laid down, the breathable membrane can be easily placed on top, ensuring a secure and effective moisture management system without complicating the installation process.

Step-by-Step Guide to Using Breathable Roof Membrane and Roofing Felt Together

Step 1: Prepare the Roof Deck

Begin by ensuring that the roof deck is clean, dry, and free of debris. Inspect the surface for any damage that may need repair before installation begins.

Step 2: Install Roofing Felt

Lay down the roofing felt over the entire roof deck, overlapping the edges as per manufacturer recommendations. Secure the felt using roofing nails, staples, or adhesives to ensure it adheres well to the surface and provides a solid waterproof layer.

Step 3: Apply the Breathable Roof Membrane

After the roofing felt has been installed, unroll the breathable roof membrane on top. Ensure that it overlaps at the seams and is securely fastened to prevent any moisture ingress. The breathable membrane will work in conjunction with the felt to create a highly effective weather barrier.

Step 4: Install Final Roofing Material

Once both the roofing felt and breathable membrane are in place, proceed to install the final roofing material, whether it be shingles, tiles, or metal panels. The combination of these components will provide excellent protection against the elements.

Step 5: Regular Maintenance

After installation, perform regular inspections to ensure that both the roofing felt and breathable membrane remain in good condition. Look for signs of wear and tear, and clear any debris from gutters to maintain effective water drainage.
