Denver Roofing: Article About Getting Commercial Buildings Ready For Winter
Winter rain and snow, along with temperature fluctuations, can be as harsh on a building's roof as it is on the roads. Taking the time to winterize commercial buildings can pay off in fewer maintenance costs later on. When business owners have the roof inspected and see to any needed repairs before winter conditions set it, they can help protect their employees as well as their investment.
Although single ply membrane systems are tough enough to survive the winter unscathed, defects do need to be attended to in order to avoid premature failures. Property damage can be significantly reduced with a little forethought and care. For example, all exterior walls and siding should be checked for cracks, water stains or leaks. Ensuring that everything is tightly sealed will help keep warm air in and cold air out. This is also a good time to inspect the windows for air leaks and cracks. Repair any caulking that might have crumbled.
Common roof defects that Denver roofing contractors see are membranes splitting at the seams, punctures or deterioration of the membrane itself. Other critical issues might be blisters or ridges.

Single ply systems that were mechanically attached need to be inspected by a professional to make sure the fasteners are tight. Loosened fasteners can potentially puncture the membrane. Membranes need to be strong and secure enough to handle wind bursts as well as rain, snow and hail.
Most roof leaks are due to damaged flashing or tears in the membrane. Therefore, these important areas of the roof need to be closely examined for defects. Trouble spots include areas where the flashing might have lifted up, buckled or worked itself loose. Roof penetrations and coverings also need to be checked out by a professional contractor and resealed if necessary. In addition, it is also a good idea to have low hanging tree branches that extend over the roof trimmed back and the roof cleared of any debris before winter sets in. Once trapped underneath a layer of snow, tree branches or sharp objects could puncture the membrane.
Gutters, drains and downspouts should also be cleaned of dirt, mold and other debris in order to make sure they are working efficiently. Anything that could potentially impede water flow, such as small rocks, leaves or twigs, can cause the water to back up onto the roof or spill over the top of the gutters. Wet walkways are potentially dangerous for clients and personnel, especially if they freeze into pools of ice.
