Federal Way Roofing: Article About Choosing Torchdown Roofing
Federal Way roofing contractors have numerous material options to satisfy all customers from traditional shingling to torchdown roofing. When homeowners request a torchdown procedure, they must have experienced contractors on the job. Instead of basic nails holding the roofing material down, torchdown installations use heat to bind the layers together and adhere to the structure's top surface. Torchdown is only meant to be used on specific properties as estimated by a professional.
Torchdown roof installations work best on flat or low-sloping roofs. The materials involved create a smooth, black surface for most installations. There are no attractive layered shapes, such as shingles, to break up the surface's visual appearance. Essentially, these roofs are meant for structures that don't have a real visible rooftop. Apartment units and tall buildings are perfect examples of low or flat roofs meant for torchdown installations.
Homeowners choose between two or three layers for their installation. A base layer and top torchdown section make up the two-layer option. Three-layer options consist of the base, smooth section and granular materials gracing the top coat. Although materials do vary, most contractors use some form of polymer modified asphalt within the layers to support and bind them together effectively.
Contractors measure and lay the roofing out in layers, verifying each section is flush with the rooftop.

They use blowtorches to heat up the surface evenly as the layers meld together into a strong barrier against moisture. It's crucial to have contractors with extensive experience because working with blowtorches does pose a threat to the home itself. Improper installations can lead to fire and other structural damage.
When installed correctly, torchdown roofs have a lifespan of 15 or 20 years. The three-layer system usually lasts longer than the two-layer, but it also depends on the installation expertise. Any missed areas could cause roof layer failure, reducing the entire system lifespan. Homeowners should be aware of any contractor's or manufacturer's warranties applied to the installation to ensure a long roofing life.
Because torchdown roofs are common for flat surfaces, contractors usually take the structure's maximum weight load capacity into consideration during the quoting process. Snow and other debris can pile up on the roof, causing stress to the structural supports. If the structure isn't strong enough for basic winter weather, contractors may suggest another material option that adds some slope to the roof. Torchdown roofs merely protect the structure from weathering elements and don't add extra support to the home itself.
