Commercial buildings can have either gable roofs or flat roofs. There are advantages and disadvantages to each type, including differences in repair frequencies and techniques. If you are planning to have a commercial property constructed, modified or expanded, you may be wondering which type of roof you should choose. If so, the following information may be helpful.
Flat Roof & Gable Roof Repair – What Is a Flat Roof?
Despite the name, a roof should never be truly flat. Most roofing contractors prefer to call them low-slope roofs. These roofs have a slight pitch that helps them shed water; water would simply remain on top of a truly flat roof until it evaporated. However, if you were standing on the roof, you would likely be unable to detect the pitch.
Low-slope roofs are frequently used on commercial buildings for a variety of reasons.
• They are economical to install.
• They offer better utilization of the interior space.
• They provide a safe location for HVAC units, solar panels and other components.
• They are less likely to suffer wind damage than gable roofs.
What Is a Gable Roof?
A gable roof features two roofing planes that meet at a ridge line across the top. The roof edges frame a triangle on the end walls. Although gable roofs are the most popular choice for residential buildings, they have become increasingly popular for commercial buildings as well. Other than aesthetics, the greatest benefit offered by a gable roof is its ability to shed water quickly. The attic space typically enhances ventilation, but it does so at the cost of usable interior space due to the slope of the roof planes. Gable roofs are more susceptible to wind damage than low-slope roofs.
Repair and Maintenance
Whether you choose a gable roof or a low-slope roof, you will need to provide proper maintenance and timely repairs. If neglected, either type of roof can leak or possibly even collapse.
• Water stains on the ceiling or walls typically indicate a roof leak regardless of roof style.
• Low-slope roofs often require more maintenance, but they are easier and safer to access.
• When installing or moving equipment on a flat roof, make sure that the technicians know how to avoid damaging the roofing materials. For example, heavy objects should never be dragged or shoved across the roofing membranes.
• Water that pools on a flat roof can indicate a drainage problem. Correcting the issue quickly can help avoid leaks and costly repairs.
• Roofs should be inspected at least twice each year and after every instance of severe weather. Professional inspections can help you identify and repair the damage before it worsens.
• Choose a contractor with experience in repairing the type of roof on your building. Many contractors who have only performed repairs on asphalt shingles, for example, lack the equipment, materials and training to repair a flat roof.
