Dry Ridge
Dry ridge is a mechanical fixing system for the ridge tiles along the top of a pitched roof. The selected system and its supporting details need to suit the roof, rather than treating every ridge as the same installation.
Dry Verge
Dry verge finishes and protects the exposed verge edges of suitable pitched roofs, usually along the gable ends. It addresses a different part of the roof from the ridge, and suitability depends on the covering and roof construction.
Neither term means fascia or soffit replacement. Those are separate roofline components and may be discussed as additional work where relevant. Dry-fix systems also vary; the proposed specification needs to be agreed for the property.
