If you’ve ever wondered how to install a flat roof without a scaffold, you’ve probably heard of torch down roofing. But what exactly is torch down roofing? The answer to this question depends on your roof and your personal preference. There are many pros and cons to this type of roofing, so be sure to do your research before you begin. There are a few basic steps to follow before you begin torch down roofing. Here are a few of the benefits.
To begin with, this type of roofing is usually made of several layers of modified bitumen or granulated mineral surface. There are also other types, such as thermo-infused film or reinforced polyester, that use this type of roofing. A torch down roofing contractor will unroll each sheet to install it. Usually, it takes three sheets for a two or three-layer roof. To determine which type of roof is best for your home, search for a roofing contractor in Washington, D.C.
While torch down roofing is a great option for homes with a slight pitch, it’s not a good option for flat roofs that are prone to punctures. These types of roofs tend to be considerably thicker than standard PVC membranes. This thickness helps prevent condensation as heat moves from the interior of the home to the exterior. To prevent condensation from forming, choose dark-colored torch down roofs. Darker colors absorb solar radiation, preventing water from collecting. As a result, these types of roofs also vaporize moisture that was gathered during condensation.
When installed correctly, torch down roofs provide excellent insulation for any property. Unlike self-adhering materials, they offer a waterproof seal and high UV reflective capabilities. The only drawback to torch down roofing is that UV rays can penetrate thin, single-ply membranes, but torch down roofing can make this a more affordable option. A torch down roof can be easily applied and can be rolled on easily.
The first layer of torch down roofing is the base sheet. This layer of modified bitumen is typically applied over an underlay board. The base sheet is usually attached to the overlying boards by hot mopping or adhesive. The second layer is called the cap sheet. The cap sheet is attached to the base sheet by applying heat. The three layers are then fused to create a water-tight seal. And to top it all off, a third layer of granules is added to the surface.
Another type of torch down roofing is PVC. This material is extremely durable and is available in two or three-ply systems. It can be used on residential or commercial buildings. It comes with a 40-year warranty. There are pros and cons to both, but they both have their advantages and disadvantages. The advantages of torch down roofing over other roofing systems are outlined below. The pros are:
