A roof covers your main structure, which includes structures and materials needed to support it, providing total protection against wind, rain, sunlight, extreme temperatures, and general weather conditions. A roof covering may be as simple as a roof membrane or shingles to a more complex system such as a gutter system. A roof membrane is a waterproofing membrane that functions as a covering for the roof of a structure. It functions to weather the elements by holding water back. A roof membrane system is typically made of synthetic rubber or other similar materials to make it as effective as it can be.
Layers
A roof covering usually consists of two primary layers. The first layer is the main article, which is generally comprised of tiles or metal sheets. The secondary article consists of materials that serve to reinforce the main article, such as nails and cleats, as well as other materials that can add to the strength and durability of the roof. The roof system is composed of many parts, each with an effect on the performance and durability of the roof itself. These various parts include:
Sloped roofs are usually pitched towards the back of the house. The pitch of a roof is its angle with respect to the actual roof slope. Frequently, pitched roofs are designed with a slight slope towards the back of the house in order to provide the roof with additional stability. However, pitched roofs may also be pitched in an opposite angle from the main building, such as towards the east or west. Different roof systems may provide different advantages, depending on the circumstances.
Low pitch roofs are not pitched; they are flat roofs that have a slight slope to them. Typically, a low pitch roof has less weight installed on it than a pitched roof. Flat roofs are more durable because there is less potential for water damage. They are also easier to repair when they are damaged because the roofing material is not exposed to water damage.
Insulation
Pitched roofs are typically constructed with plywood panels that are insulated between the panels. The insulation is typically made of wool insulation, which provides excellent thermal insulation in cold climates. If a roof does not have enough insulation, especially in colder climates, then the roof could easily freeze. Without enough insulation, the heat that comes in from the inside can cause the roof to overheat, leading to excess moisture in the attic. This moisture can cause expensive repairs and damage to the roof itself.
Roofs are available at different degrees of slope, which can affect both their installation and maintenance. A flat roof may require little maintenance, but a sloping roof requires more maintenance in order to stay in good condition. In extremely cold climates, flat roofs may not provide the insulation that is needed in winter, so extra insulation is necessary. Once the roofing material has been chosen and the roof slope has been selected. If you’re looking for more information on roofing installation in Ottawa, contact our team today.
