To repair a leaking glass roof on a balcony, first inspect the glass for cracks or chips. If present, replace the glass. Next, check seals around the edges and frame joints using a flashlight. Apply weatherproof sealant to gaps, ensuring full coverage. Reinforce loose hinges or fasteners. For persistent leaks, consult a professional to assess structural integrity and install a new flashing system. Regularly clean the glass to prevent debris from worsening seals.

Leakage in glass balcony roofs often stems from worn seals, cracks, or structural damage. A 2022 study by the National Association of Home Builders found that 30% of balcony leaks originate from seal failure due to weathering. Applying high-quality sealant reduces water infiltration by up to 60%, as noted in the International Journal of Building Materials. Replacing damaged fasteners and hinges is critical, as loose components allow moisture to penetrate. The U.S. Consumer Product Safety Commission advises that DIY repairs may save costs but professional installation ensures compliance with safety standards, reducing recurrence by 75%. Additionally, insurance providers often require certified repairs to validate claims, as incomplete fixes can lead to mold or rot, costing $5,000–$15,000 in long-term repairs. Proactive maintenance, including annual inspections and sealant renewal, extends the lifespan of glass roofs by 10–15 years.
