All Around Roofing: Honest Roofing Companies Denver
Many business owners with flat roofs often find that these structures have different maintenance requirements than residential roofs do. Flat, commercial Denver roofing is especially prone to snow build up and often requires professional care to remain in good structural condition. Business owners may wonder where to start when dealing with roofing issues. Here are some tips for flat roof maintenance.
The flat rooftops that are most often seen in the roofing of commercial buildings are not actually flat. They have a very slight slope that helps to remove standing rainwater and snow melt from the roof. This prevents damage and reduces the likelihood or severity of potential roof leaks.
Despite having this minor slope, flat roofs still require maintenance to keep them clear of debris that can include limbs, twigs, leaves and bird nests. If a roof is not cleared on a routine basis, a layer of soil or mulch substantial enough to become a source of plant growth can form, which can damage the roofing materials.
Leaves can also block roof drains, adding to the amount of heavy, free standing water on the roof. The water can reduce the lifespan of the roof. The high moisture level can also attract mosquitoes and other pests. Depending on the climate, a poorly draining roof can also increase the potential for mold or mildew growth.
A professional roofing company can perform maintenance seasonally for business owners, along with scheduled inspections, to repair leaks or to catch the early warning signs of roofing damage. Maintenance is most important in the fall and spring, after the leaves have fallen and all of the snow has melted. These are the best times to invest in keeping a roof in good condition.
Repairing a flat roof is different from conducting repairs on a sloped roof with shingles. Although they are typically easier to work on, flat roofs require an experienced professional perspective to locate or identify many of the problems they experience. Additionally, many different types of flat roofs exist. The most popular of these include the tar and gravel based Built up Roof (BUR), modified bitumen and a rubber membrane.
BUR is becoming a less popular choice. This is due to its excessive weight and the tendency for the gravel layer to clog gutters. Rubber membrane roofs are considered energy inefficient, making the interior of the structure hotter due to heat absorption. In addition, rubber roofs are not very budget friendly. Modified bitumen represents the middle ground on these characteristics, including weight, energy efficiency and overall cost.
