Frequently asked questions
What is a dry verge system exactly?
It's a mechanically fixed plastic or GRP unit that replaces traditional mortar bedding at the roof edge (verge), holding tiles securely without relying on mortar that can crack over time.
Is dry ridge better than traditional mortar ridge?
For most modern roofs, yes — dry ridge systems avoid the recurring cracking and re-pointing that mortar ridges need over their lifetime, and often add roof ventilation too.
Can dry verge/ridge be fitted to an existing roof, not just new builds?
Yes, we regularly retrofit dry verge and dry ridge systems to existing roofs, particularly where mortar bedding keeps failing.
Does a dry ridge system affect how the roof looks?
Modern systems are designed to closely match traditional tile profiles, so the appearance from ground level is very similar to a mortar-bedded ridge.
