Rooftop equipment such as satellite dishes, AC (air conditioner units), and other forms of communication equipment may increase your roof's risk of damage. Here are some of the reasons for this increases risk:
Increased Frequency of Foot Traffic
Installing equipment on the roof increases the rate of foot traffic on the roof. People will go up on the roof to install the equipment, perform inspections, and fix damages that may crop up from time to time. Unfortunately, the more people walk on the roof the more likely the roof is to get damaged.
The damage occurs in several ways; for example, the weight of people walking on the roof can crush the roof insulation, especially in single ply roofs. At the same time, friction between shoes and asphalt shingles can strip the protective granules off the shingles, exposing them to weather damage. Indeed, all roofing materials experience accelerated wear and tear when exposed to high foot traffic.
Interference with Roof Continuity
A continuous roofing material is more likely to withstand weather damage or regular wear and tear than a roofing material that is broken up into different sections. Unfortunately, you will have to interfere with your roofing material's continuity when installing equipment on the roof. You have to drill holes on which to nail, screw or anchor the equipment. You may also need to cut away some sections of the roof to install electrical conduits or pipes depending on the equipment you are installing.
Improper Sealing or Waterproofing
In most cases, roof problems begin at joints, such as the joint between the roofing material and installed equipment such as an air conditioner unit. Installing a flashing material and waterproofing the joint usually takes care of the problem. The more equipment you install, however, the higher the risk that some of the joints may not be properly sealed, increasing the risk of water damage.
Occurrences of Water Pooling
Some forms of rooftop equipment produce condensation, especially if they malfunction. For example, a malfunctioning air conditioner unit (especially if it has been improperly maintained) may produce condensation that may collect and pool around the unit with time. Some rooftop equipment may also trap snow and ice on the roof, which may also melt and contribute to ponding. The more such water stays on the roof the more it is likely to soak into the roof and damage it.
Therefore, if you are planning to install rooftop equipment, ensure they are installed by experienced professionals. After that, you should inspect and maintain your roof regularly to preempt the aforementioned damages. For more information, contact companies like Advanced Roofing and Construction.
