Garrdal is a 2-part pipe flashing designed to go where other flashings won't! Obstacles such as electrical masts, high-efficiency appliance stacks, concentric pipes and any other pipes with challenges are no longer a hindrance with Garrdal 2-part flashings.

They are American made, easily installed and look great on any type of roof. Handy for any installation or retrofit project, these are a must-have on every work truck. Made of UV-resistant co-polymer and UV-resistant TPE, Garrdal is extremely durable. While comparable in cost to other retrofit pipe flashing accessories, Garrdal's unique versatility stands apart from the rest.
