Skylights on flat roofs bring beautiful natural light into a home or commercial space, but they also come with added challenges. Unlike sloped roofs, flat roofs don’t shed water as easily. This means skylights on flat roofing systems are more vulnerable to leaks, pooling water, and long-term damage. Understanding these challenges—and the solutions—can help Vaughan homeowners keep their skylights in great condition.
Why Flat Roof Skylights Leak
The main issue with flat roof skylights is water pooling. When flat roof systems don’t have proper drainage, water collects around the skylight frame. Over time, this increases the risk of leaks. Poor flashing installation, deteriorated roofing membranes, and clogged eavestroughs only make the problem worse.
Signs of Trouble
Homeowners should watch for water stains around skylights, peeling paint, or bubbling on the ceiling. These are signs that water is getting inside. In Vaughan’s climate, freezing temperatures can worsen leaks, as trapped water expands into small cracks. Flat roofs are also prone to thermal movement, which can cause seals around the skylight to fail.
Repair Options
Professional skylight repair services typically begin by checking the flashing and membrane around the skylight. Repairs may include resealing membranes, replacing old flashing, or adjusting the slope to direct water away from the skylight. If the skylight itself is old or damaged, replacement might be the best option. For urgent leaks, emergency roof repair services provide temporary solutions to prevent water damage until permanent repairs can be made.
Preventive Maintenance
The best way to prevent flat roof skylight issues is through regular inspections. Homeowners should have their roof checked twice a year—especially in spring and fall. Keeping drainage clear is also critical. Blocked eavestroughs and downspouts force water back onto the roof, putting pressure on skylights. Proactive maintenance ensures skylights remain watertight even in Vaughan’s toughest weather.
Why Local Expertise Matters
Flat roofs and skylights require specialized knowledge. Not every contractor has the experience to properly diagnose and repair these systems. Vaughan homeowners should work with contractors who specialize in both roofing Vaughan and skylight repairs, ensuring long-lasting results.
Final Thoughts
Flat roof skylights add light and beauty, but they require careful attention. By addressing leaks quickly, scheduling inspections, and working with skilled roofing experts, homeowners can enjoy their skylights without constant worries about water damage. A well-maintained flat roof skylight can last for decades, protecting both your investment and your comfort.
