Designed for the extreme demands of slate roofs, TopSlate is ideal for applications which require maximum longevity and strength. It is as durable as the slate roof it completes and strengthens weak, wind-vulnerable perimeters. Castle Metal Products offers TopSlate Ridges with optional vents and baffles.
TopSlate Ridges eliminate the unsightliness of roof cement, seams, and exposed fasteners. The elegant simplicity of slate installation typically comes to a sticky, messy halt when the final perimeter slates are applied.
In conventional installation, roof cement is used in an attempt to fill ridge and hip seams and to cover nail holes. However, roof cement only lasts 5-10 years when exposed, which means it is not compatible with best practice slate installation.
High-grade slate lasts 75-125 years, which means it needs a finishing component that is of equal longevity and quality. The principle components of TopSlate are made to last because they are 2.5 times thicker than typical, prefabricated, external flashings and vents.
