Skylight & Sky Tunnel Installation in Guelph, Midland & Ontario
Natural light transforms a home. Weldun Roofing installs and repairs skylights and sky tunnels (tubular skylights) across Guelph, Midland, and surrounding Ontario communities. As roofing specialists, we ensure every skylight is integrated seamlessly into your roof system — no leaks, no compromises.
Skylight Services
- New skylight installation — We cut the opening, reinforce the framing, install proper flashing and ice-and-water shield, and set your new skylight to manufacturer specifications.
- Sky tunnel (tubular skylight) installation — Perfect for bathrooms, hallways, and closets where a traditional skylight isn’t practical. A small roof-mounted dome channels daylight through a reflective tube into the room below.
- Skylight replacement — Old, foggy, or leaking skylights can be replaced with modern energy-efficient units without replacing your entire roof.
- Skylight repair — Condensation, cracked glass, or failed seals? We diagnose and fix skylight issues before they cause water damage.
- Skylight flashing replacement — Most skylight leaks are actually flashing failures, not skylight failures. We replace the flashing system around your existing skylight.
Why Install a Skylight?
- Natural light — Skylights bring up to 3x more light than a same-sized vertical window, reducing your need for artificial lighting.
- Energy savings — Modern skylights with Low-E glass and argon fill provide excellent insulation while letting light in.
- Ventilation — Venting skylights open to let hot air escape from upper floors — especially valuable in Ontario summers.
- Home value — Skylights are consistently rated as a feature that increases home resale value.
Best Time to Install
The ideal time to add a skylight is during a roof replacement — we can integrate the skylight into the new roof system at a fraction of the standalone cost. But we install skylights year-round on existing roofs as well.
