A roof is a vital part of a home or building that shields against rain, snow, sunlight, and wind. It’s also important to know some basic facts about roofing.
Residential roofing involves working on single-family homes and multi-unit housing complexes. It requires workers to safely navigate residential neighborhoods and access rooftops using ladders or scaffolding.
Insulation
Upgrading your roof's insulation is one of the most cost-effective home improvement projects. It cuts energy bills and makes your house more comfortable year-round. The upfront expense is recouped quickly and keeps paying dividends over time.
Insulation is available in a variety of forms, fitting different needs and roof types. Foil or paper-backed fiberglass or mineral wool is usually blown in place, but spray foam can be applied as well. These products offer high thermal resistance with relatively low weight. Foil insulation is safe and non-toxic, and does not release any harmful chemicals or VOCs into the indoor environment.
Rigid panels — such as extruded polystyrene (XPS) — are also available for a wide range of applications. They have high insulation values and require less maintenance than other types of roof insulation. They are suitable for flat or pitched roofs that have a waterproof membrane, but should not be installed in sloping areas that can collect water or moisture.
Durability
Durability is a major consideration for homeowners when choosing roofing materials. The best roofing materials are able to resist the elements, withstanding rain, snow, sunlight and extreme temperatures. A durable roof will need less maintenance, saving homeowners money in the long run.
Wood shakes are a popular choice for durability, offering a lifespan of 30 years and a natural look. However, they are susceptible to fire and need to be regularly inspected for damage.
Concrete and clay tiles are another roofing option, with lifespans of 50 years or more. They can withstand heat, hail and snow and offer Mediterranean aesthetic appeal. However, they are heavy and require additional framing to support their weight.
Metal roofing is gaining popularity as a durable, attractive option. It is available in a wide range of styles to complement any architectural design. It also provides longevity, reducing maintenance and energy costs over time. In addition, it offers resistance against fire and rot, while being easy to install.
