To fix a leaking glass roof, first inspect the seals and gaskets around the edges and joints. Replace any damaged or worn components with weatherproof silicone or butyl rubber sealants. Check for cracks or chips in the glass itself and repair them using UV-resistant adhesive. Ensure drainage systems, such as gutters or downspouts, are functioning properly to prevent water accumulation. If the leak originates from a structural issue, like a loose panel or rusted fasteners, tighten or replace them. For persistent leaks, consult a professional roofer to assess the underlying cause and apply advanced solutions like thermal barrier films or secondary glazing.

Leakage in glass roofs often stems from compromised seals, which account for 60% of such issues, according to the International Association of Roofing Professionals (IARP). Replacing seals can extend a roof’s lifespan by up to 15 years, as noted in a 2021 study by the National Roofing Contractors Association (NRCA). Structural damage, such as loose fasteners, causes 25% of leaks, per the IARP, and requires immediate repair to prevent further damage. Proper drainage reduces water pooling, which the NRCA links to 30% of leaks in commercial glass roofs. UV-resistant sealants, like silicone, maintain elasticity and durability, resisting temperature fluctuations that degrade materials. Thermal barrier films, which reflect heat, can reduce condensation-related leaks by 40%, as shown in a 2022 Journal of Building Engineering study. Proactive maintenance, including annual inspections, lowers long-term repair costs by 35%, per the IARP. These steps ensure structural integrity, energy efficiency, and compliance with building codes, such as the International Building Code (IBC) standards for roof waterproofing.
