According to building maintenance experts, up to 40% of roof leaks in homes originate from poorly sealed skylights. Proper skylight sealing is crucial to protect your property from water damage, heat loss, and costly structural issues. Over time, exposure to UV rays, temperature changes, and weather can cause sealant to dry out and crack. Professional skylight sealing services address these problems by resealing the perimeter and ensuring a watertight barrier. Contractors inspect flashing, glass, and insulation to identify any weak points that could lead to leaks. A well-sealed skylight improves energy efficiency and prevents mold or interior staining. Choosing expert skylight sealing not only protects your home but also enhances comfort and durability year-round.
3 Signs You Need Skylight Sealing

Condensation Between Glass Panes: Fog or moisture inside the skylight’s glass suggests sealant degradation or gaps in insulation.
Drafts or Temperature Changes: If you feel air leaking near your skylight, resealing is necessary to restore energy efficiency.
Before vs After Skylight Sealing
Before: Leaks, drafts, and visible wear around skylight edges.
