Looking for leaks target and seal crack, joints and roof penetrations with a brush and Liquid Rubber Seal, use membrane if necessary.
- Roof penetrations: The most common leak is around a pipe, vent, skylight, cable, chimney parapet wall or anything that penetrates through the roof.
- Roof materials: Cracks, splits and holes can form in aging roof materials. If small areas of the roof have become brittle, water can seep through tiny cracks, which may not look like a leak source.
