Flat roofs have been a go-to roofing option for both homeowners and businesses alike. But, they are prone to annoying leaks at times. These leaks can arise for an array of reasons. Poor installation workmanship, aging membranes, roofing material damage, lead flashing leaks, and clogged gutters are some of the primary suspects.
Poorly Installed Roofing Membranes
According to reputable insurance companies, poor workmanship during installation is one of the leading causes of flat roof leaks. These insurance heavyweights have reported that leaks usually occur within two years of installation. A disheartening fact is that most flat roofing systems are not covered by insurance-backed guarantees. The outcome? The roofing contractor is not held accountable for any faults that may emerge.
Solution – To steer clear of this predicament, it is of utmost importance to select a reliable flat roofing specialist. The selected expert should be capable of conducting a comprehensive survey to assess any damage. Only then can you rest assured that your flat roof will remain leak-free. We recommend selecting a flat roofing system with an insurance-backed guarantee to ensure coverage beyond the contractor.
Aging Membranes
Aging membranes are another common cause of flat roof leaks. Over time, older flat roofing membranes become more fragile and susceptible to damage. The paint designed to reflect UV rays can wear away, leading to splitting and blistering of the membrane. This problem is often worsened by general wear and tear and freeze-thaw cycles during the winter.
Solution – For small areas or patches, a temporary fix can be applied using a repair system, or an overlay can be used to cap the roof and preserve the insulation and decking.

Damage to the Flat Roofing Material
Damage to the flat roofing material is also a frequent cause of punctures and leaks. This damage can be caused by physical impacts, such as people carelessly walking on the roof or sharp-edged equipment being moved across it. Single ply roofing systems are particularly prone to this type of damage when incorrectly specified. Additionally, sharp objects like gravel can become trapped in shoes and cause tears.
Solution – To prevent such damage, we recommend choosing a stronger and more durable fiberglass GRP flat roof for foot traffic or equipment placement. If you have a single ply flat roof in place, a polyurethane coating can be applied to areas prone to tearing to provide enhanced protection.
Leaking Lead Flashing
Lead flashing is another common source of flat roofing leaks. Lead flashing, which is located at the intersection between the brick wall and the flat roof or other roofing features, is designed to provide waterproofing in these areas. However, it can also be a source of leaks if it degrades over time or hasn’t been fixed to the brick wall correctly via cheap adhesives.
Solution – To address this issue, it’s essential to inspect and repair the lead flashing. We recommend seeking the help of a skilled specialist for diagnosis and repairs.
Lack of Maintenance: Blocked Gutters
Lack of maintenance, specifically blocked gutters, is a frequent cause of flat roofing leaks. Blocked gutters can lead to water overflowing into the adjacent roofing structure, causing leaks.
Solution – In almost all cases, we recommend performing or arranging for gutter clearing and unblocking. Additionally, regular gutter maintenance is crucial to prevent future leaks. Depending on the extent of any water ingress, some remedial flat roofing work may be required.
Flat roofs are prone to leaks, but there are solutions to the most common causes. It’s essential to choose a reliable flat roofing specialist, select a flat roofing system with an insurance-backed guarantee, and perform regular maintenance, including clearing and unblocking gutters. By taking these steps, you can ensure the longevity and durability of your flat roof. Remember that prevention is always better than cure, so address any issues promptly and don’t hesitate to seek professional help.
