Homeowners typically consider many factors when they look into the materials for their roof. Things such as durability, longevity and visual factors can all play a role in the final decision. However, many homeowners also consider the role that noise will play when they purchase their roofing installation. Federal Way roofing professionals provide many standard and unique roofing options, and customers interested in getting the most out of their installations should consider noise as a factor to watch out for. Metal roofs, in particular, have long been associated with a noisier overall atmosphere. Homeowners believe that these roofs accentuate the acoustics resulting from environmental effects such as rain and snow.

Studies show that metal covered rooftops are not always noticeably noisier than any other type of roof covering. During certain tests, customers noticed no difference between metal shingles and asphalt ones when it came to noise levels. The level of noise may depend on any variety of factors, including the choice in metal, the fastener method and the roof insulation. With a solid and well insulated roof, homeowners can expect minimal sound during events such as rainstorms.

Noises are usually transmitted through the roof and into the building through two methods. The first method is through airborne sound when the sound waves travel through the air and move into open building areas, such as doors and windows.

The second method is mechanical transmission. This is when sound moves through solid building structures such as the walls, framing and floors. Different building configurations will result in different degrees of mechanical transmission.

For the most part, roof noises may be attributed to obvious outdoor sources. Rain, hail and different types of thermal movements, such as contractions and expansions, all translate to noise within the home. Sometimes transmitted sounds from nearby external sources, such as trains, trucks and even airplanes can also play a role according to how the roof receives them. Sometimes loud booming noises may be heard in colder environments, owing to the sound of water freezing and fracturing certain roof elements and sections.

There are many different choices that homeowners can make in regards to their roofing to help reduce the noise levels. Different materials are specifically designed to reduce sound transmissions through the roof. Most experts will recommend concrete and clay as the most effective options. Because of their higher mass and density, these materials are better at muffling sounds, particularly in noisier outdoor environments. Metal roofing may be installed over plywood and other insulators to further help cancel out noise.
