What are Roofing Felts

Roofing felts, also known as tar paper or roofing tar, are materials employed in the construction of buildings to provide an additional layer of protection to the roof structure. Designed to shield the roof from water infiltration and damage, roofing felts are typically made from a base material such as fiberglass or polyester, which is then coated or saturated with a protective layer of bitumen. This combination creates a water-resistant barrier that lies underneath the main roofing material, whether that be shingles, tiles, or metal panels.

Intended for use by builders, contractors, and developers in the construction and renovation of various types of buildings such as homes, offices, warehouses, and more, roofing felts play a crucial role in ensuring the longevity and durability of roof structures. The principle behind their effectiveness is simple: they act as a secondary barrier to water, preventing leaks and moisture build-up that can lead to mold growth, wood rot, and structural damage. By repelling water and providing an extra layer of insulation, roofing felts also contribute to a building's overall energy efficiency.

The installation of roofing felts is integral to the roofing process. After the roof deck is prepared, rolls of felt are rolled out and nailed or stapled into place, overlapping each other to prevent any gaps where water could potentially penetrate. In some cases, self-adhesive felts are used for easier application. The main roofing material is then installed on top of this protective base. While often hidden from view upon completion of the roof, the presence of roofing felts is essential for maintaining the integrity of a building's envelope against environmental factors.

Types of Roofing Felts

The various types of roofing felts available cater to different requirements and preferences within the construction industry.

  • Fiberglass-based Felts: These are known for their durability and resistance to tearing. Fiberglass felts are often chosen for buildings where a sturdier underlayment is necessary due to harsh weather conditions or when a longer-lasting solution is preferred.

  • Polyester-based Felts: These are more flexible than fiberglass options and are particularly useful in regions where roofs may experience movement or shifting. They can adapt well to changes without compromising their protective capabilities.

  • Bituminous Felts: Traditional bituminous felts contain asphalt or coal-tar pitch combined with organic fibers. They are commonly used for their proven track record in waterproofing and their ease of installation on various types of roofs.

  • Self-adhesive Modified Bitumen Felts: For quick and clean installation, self-adhesive options are available, which eliminate the need for hot bitumen or torches during application. They are convenient for smaller projects or when time constraints are a factor.

  • Synthetic Underlayment Felts: Made from polypropylene or polyethylene fabrics, these high-tech alternatives offer advanced moisture protection while being lightweight and strong. They're often chosen for modern building designs that require materials with specific performance characteristics.

How to choose Roofing Felts

Selecting the right type of roofing felt for your project requires careful consideration of several factors. Assessing the specific needs of your building project is crucial as these materials serve as the backbone for effective roof protection.

Consider the climate where your building is located; areas prone to high winds or heavy rainfall will benefit from more durable felts like fiberglass-based options. Projects with complex roof designs might need more flexible materials such as polyester-based felts to accommodate angles and curves without compromising on protection.

The type of top roofing material also plays a role in choosing the appropriate felt. Heavier materials may require stronger underlayments that can support additional weight without buckling or tearing. Conversely, lighter materials like metal panels may be paired effectively with synthetic underlayment felts that offer superior water resistance while still being lightweight.

Businesses focused on B2B sales should also factor in the long-term value and maintenance considerations associated with different types of roofing felts. Durable materials may have higher upfront costs but can provide savings over time due to their longevity and reduced need for repairs.

Lastly, consider any additional features offered by certain products. Some felts come with added benefits like fire resistance or eco-friendly properties which may be important depending on your client's preferences or local building codes.
