La plupart des propriétaires ne pensent pas à tous les composants présents dans le toit de leur maison, mais il se passe beaucoup de choses sous les bardeaux.
Les bardeaux sont la couche la plus à l'extérieur de votre toit et aident à vous protéger des rayons du soleil, de la pluie, de la neige et du vent. Quand vous regardez en-dessous, il existe une autre couche de protection entre le platelage et les bardeaux. C'est la sous-couche qui joue un rôle crucial dans la protection de votre maison contre les dommages causées par l'humidité.
What Is Roof Underlayment, and Why Is It Important?
This layer of your roof system is typically made of asphalt saturated felt or modern synthetic materials. It covers your entire roof deck, acting as a secondary moisture barrier between the roof deck and the overlying shingles (or other roof covering) to help prevent wind-driven rain from infiltrating your home through the roof.
In other words, it helps keep your home dry. It's just one of many layers of materials that make up your roofing system, and all of them have to be installed properly for your roof to provide the best protection against the elements.
What Are the Different Types of Roof Underlayment?
Roof underlayment is usually made of either asphalt-saturated felt or synthetic materials. In either case, it provides a secondary water-shedding layer of protection that helps keep water during a rain event from infiltrating your home. GAF offers several types of roofing underlayment for different types of homes and price points.
Deck-ArmorMC
Combining strength with it's premium breathable technology, Deck-Armor™ Premium Roof Deck Protection helps protect your home from wind-driven rain and trapped moisture. Trapped moisture can lead to the growth of mold, mildew, or rot, which can result in damage to your roof system. This lightweight, slip-resistant roofing underlayment is easy for workers to install, even on steeply pitched roofs. It's breathable technology makes it an excellent choice for premium roof systems.
Tiger PawMC
Tiger Paw™ Roof Deck Protection is a premium, UV-stabilized synthetic roof underlayment with a moisture-control design that helps to reduce moisture on the roof deck and provide a strong layer of protection against wind-driven rain that can damage your roof structure or home interior. Recommended for asphalt shingles, slate, wood, metal, or mechanically-attached tile roofs, this layer combines strength and resilience, so it won't rot or get brittle. It also resists buckling to give your roof a smooth appearance and is specially designed to provide excellent walkability for roofers.
FeltBusterMD
The value-priced FeltBuster® Synthetic Roofing Felt is a polypropylene underlayment. Its durable construction helps it resist tearing and it won't absorb moisture that can lead to disintegration over time. It lies flatter than typical felt for a sleek looking roof.
Shingle-MateMD
For another fiberglass-reinforced roofing felt option, Shingle-Mate® Fiberglass-Reinforced Roof Deck Protection acts as a secondary layer of protection against wind-driven rain. Conventional asphalt felts can bubble or wrinkle when they come in contact with moisture, which can detract from the look of your finished roof. Shingle-Mate's fiberglass reinforcement helps it lay flat and reduces wrinkling for a great finished look.
VersaShieldMD
VersaShield® Fire-Resistant Roof Deck Protection helps many roofing systems achieve a high UL fire rating* while providing a secondary layer of protection against wind-driven rain. The fiberglass reinforcement helps keep it flat for a great finished look.
