Why Timing Matters
Skylights are the #1 leak source on roofs — not because skylights are bad, but because the flashing around them is often done poorly. Installing a skylight during roof replacement means the flashing integrates with the new roofing as one system.
Replace Old Skylights
If your skylights are as old as your roof, replace them during re-roofing. Old acrylic domes yellow and crack. New glass skylights with Low-E coating are more energy-efficient and clearer.
