Low sloping roofs are susceptible to certain types of damage, especially at the seams and edges. Preventing damage caused by wind and water getting under the edge of the roof requires careful attention by roof services, so the roof is well-sealed. Roof edging systems are essential in protecting the edge of a flat or low sloping roof, and preventing the extensive damage that can occur when roofing is not properly protected in this way.
Wind Damage and Low Slope Roof Edges
The edge is one of the most vulnerable areas on any roof, but this is especially true on a low sloping roof. Wind can be very damaging to a low slope roof when the edges are exposed, and not properly secured. Exposed roof edges leave areas for the wind to get under the roofing material and blow upward, loosening it over time. Whether the roof is made of membrane or metal, winds that are strong enough can easily tear roofing material, or blow the roof right off when the edges are not protected.
This is a common problem experienced during hurricanes and severe storms, with the majority of the damage sustained to low sloping roofs being caused by wind. The Roofing Industry Committee on Weather Issues (RICOWI) estimates that more than 60 percent of low slope roofing failures would not have occurred if there was appropriate roof edge securement in place.
Roof Edging Systems Are Critical Protection
The best protection for both of the problems referenced above is the installation of a quality roof edging system. In many building markets, this is even required for a roof to be considered "up to code." Roof edge systems are designed for roofing services to use on flat and low sloping roofs, preventing water and wind damage by sealing off the roofing material and securing the roof edge. There are systems available for metal roofs, as well as various types of membrane roofs, each providing the necessary securement to seal roof edges so they are not exposed, and subject to various types of damage.
Choosing the Best Roof Edging System
There are a number of different roof edging products available for flat and low slope roofs, so home and building owners must ensure the company providing their roof services chooses the most appropriate one. Various building and safety organizations, including the ANSI and the International Building Code (IBC), have outlined standards for roof edging systems, and recommend that systems be tested after installation, although there is no actual stipulation of who should test these particular systems. The best suggestion in this case is to work with contractors experienced with the installation of various roof edging systems and who will use the most reliable products on the market depending upon the type of roof, the material being secured, and the strength requirements based on local building codes. In any case, roofing should always include the careful and secure application of a durable roof edging system.
The roof is the main protection a building has against the weather. Unless roofing is correctly installed to include a secure roof edging system for low sloping roofs, the entire roof is vulnerable to serious wind damage. Those who own homes and buildings with low sloping metal or membrane roofs should discuss their roofs with experienced roof services right away, and ensure they are protected with the proper roof edge securement!
