With technological advancement, the roofing system industry has evolved tremendously with different types of roofs and materials now being used in construction. Torch-applied roofs have become quite popular nowadays. Let us look at torch up-and-down roof systems that a roofing contractor in Los Angeles, CA, can offer you.
Torch or torch-down roofing utilizes sheets of modified bitumen that are burned onto a roofing surface using a propane torch. This allows the bitumen roofing materials to adhere to the roof’s surface when given the right conditions and temperatures. The roofing contractor in Los Angeles, CA will then seal the layers together to create a waterproof surface. Bitumen is asphalt combined with plastic or rubber.
Most torch-down roofs use modified bitumen well suited to seasonal climates since the roofs expand and contract without damage. Such roofing systems withstand extreme temperatures and maintain durability even when temperatures fluctuate.
Torch-down roofing systems may have either two or three layers of modified bitumen. Theta is one of the most common roofing systems for flat roofs. They feature insulation, a vapor barrier, base sheets, cap sheets, overlay boards, cap flashing, asphalt or adhesive, and base flashing. These components help to ensure the integrity and other weatherproof features of your roof.
Insulation is critical to maintaining internal building temperatures even if the weather changes. The vapor barrier prevents condensation and other problems like mold and mildew, which are associated with excess moisture. The overlay provides a level surface on which the torch-down roofing membrane is applied. The base sheet is the initial layer of the modified bitumen used directly to the overlay, and the cap sheets are the outermost membrane applied to the base sheet. Flashing is also applied around roofing features like HVAC, vents, and other penetrations.
One of the main advantages of a torch down roofing is its ability to provide weather protection even when the climate changes since it can expand and contract with weather temperatures, which means that durability is hard to beat. This type of roofing holds up well in wet climates or those climates with snow since it has teh waterproof barrier that prevents water damage to underlying structures. These systems are resistant to UV damage and reflect heat from the sun for improved energy efficiency.
Types of Torch Down Roofing
Torch-down roofing systems are of two types- two and three-layer systems. Both of them consist of a base and cap sheet. But the only difference in the three-layer system is that the roofing professional is applied on a base sheet and then on a smooth cap sheet and is finished with a granule cap sheet. The extra layer extends the life of the roof and usually enhances energy efficiency, fire resistance, color, or other features.
To Sum Up
Torch-down roofings are durable, lightweight, easy to maintain, and save energy. The installation is low cost compared to metal or tile roofing. So look for a contractor that can provide leak and fire-resistant torch-down roofing solutions at the best price.
