What are the Benefits of Flat Roofing?

For both residential and commercial buildings, there are significant benefits that make a flat roof well worth the choice. The main reason for many is cost savings: Installing a flat roof saves money on material and installation costs, and on heating bills every year after. As heat rises, it’s drawn to the heights of a traditional angled roof, requiring more energy to heat the inside of the building. A flat roof retains heat in the main part of the building, saving significantly on heating costs.

Another main benefit to installing a flat roof is the opportunities it presents: An apartment complex, office building, or other shared space with a flat roof may have a rooftop garden, lounge, or green roof to provide a gorgeous community space that raises the value of the properties within. A flat roof may also be essential to a business such as a hospital that requires helicopter accessibility, or a parking structure seeking to maximize available spots. While there are many benefits to installing a flat roof, there are also considerations to prevent costly problems in the future.

Are There Any Common Problems with Flat Roofing to Watch Out For? 

Yes, flat roofs have their own set of common problems and challenges that you should be aware of and watch out for. Regular inspections and proactive maintenance can help prevent these issues from becoming major problems. Here are some common problems associated with flat roofing:

• Water Ponding: Flat roofs are prone to water ponding or pooling, especially if the drainage system is inadequate or blocked. Prolonged standing water can lead to roof membrane deterioration and leaks.
• Leaking: Leaks are a significant concern with flat roofs. They can occur due to damaged or deteriorating roofing materials, failed seams, or improperly installed flashing. Regular inspections are essential to catch leaks early.

• Blistering and Bubbling: Over time, moisture can become trapped between the layers of roofing materials, leading to blistering or bubbling of the roof surface. This compromises the integrity of the roof and can lead to leaks.
• Flashing Issues: Flashing, which is used to seal roof penetrations (such as vents, chimneys, and skylights), can deteriorate or become loose over time. Damaged or improperly installed flashing is a common source of leaks.
• Deterioration from UV Exposure: UV radiation from the sun can cause roofing materials to break down over time, leading to cracks, loss of flexibility, and reduced lifespan.
• Ice and Snow Accumulation: In cold climates, ice dams and snow accumulation on a flat roof can lead to water infiltration and damage when the snow melts and refreezes.
• Punctures and Mechanical Damage: Foot traffic, dropped tools, or other mechanical damage can puncture the roofing membrane or damage the surface, leading to potential leaks.
• Lack of Maintenance: Neglecting regular maintenance, including inspections and necessary repairs, can exacerbate all of the above problems and significantly reduce the lifespan of a flat roof.

How Can I Extend the Life of My Flat Roof?

To address the common problems listed above and extend the life of your flat roof, it's essential to have a proactive maintenance plan in place. Regular inspections by a professional roofing contractor can help identify issues early, and timely repairs can prevent more extensive and costly damage. Additionally, keeping the roof clean and free of debris, as well as ensuring proper drainage, is crucial for flat roof maintenance.
