A skylight transforms a dark room into a bright, open space โ but only if it's installed correctly. Skylights are roof penetrations, and roof penetrations are where leaks start. Johannesburg Roofing & Maintenance installs skylights the right way: structural curb framed between rafters, ice-and-water shield on all four sides, step flashing and counter-flashing integrated into the shingle field, and a watertight seal verified from inside the attic.
The curb is the foundation of every skylight installation. We frame it between existing trusses or rafters with doubled lumber to carry the load. The roof deck opening is cut precisely โ no oversizing that weakens the sheathing. The skylight flange seals to the curb, and the flashing system integrates the unit into the existing shingle field so water runs over the flashing, not under it.
Our Skylight Installation Process
Skylight Planning
Our estimator visits your Johannesburg home, inspects the attic framing, and recommends skylight size, type, and placement. We show you product options โ fixed, vented, tubular โ and provide a detailed written estimate.
Structural Prep
We cut the roof deck opening through the sheathing and shingles, then frame a structural curb between the rafters with doubled lumber. Headers distribute the load around the opening. The curb provides a solid, level base for the skylight unit.
Weather Barrier
Full flashing system: ice-and-water shield base layer, step flashing and counter-flashing on all four sides, woven into the existing shingle field. Water flows over the flashing and onto the shingles below โ never behind them.
Final Seal & Trim
Unit installed and sealed. Light shaft insulated and trimmed. We verify the seal from inside the attic โ if we can see any daylight at the flashing joints, we re-seal before we leave. Your skylight is watertight and energy-efficient.
