Roof Drains
Efficient roof drainage is an important element of maintaining a commercial roof. Our easy-to-install commercial roof drains and dome strainers allow for effective drainage while maintaining a pleasant appearance. If you don't see what you need, contact us for additional retrofit roof drain options including vents, equipment, and accessories.
When reroofing or removing an existing drain, a replacement drain is needed. This is where retrofit drains are used, as they replace the broken or corroded roof drains easily with almost no construction. Retrofit drains are simply inserted into the existing drain pipe, and the drain’s water tight rubber seal expands outward against the existing pipe. The pressure from this seal stops water from flowing between the retrofit drain and pipe wall.
Retrofit roof drains are typically easy to install and provide near identical benefits as most normal roof drain systems. They prevent leakage and form a connection between the plumbing and drainage systems for water to flow through in place of an old drain.
When an old or broken drain is removed from the roof, a retrofit roof drain is inserted within the existing drain pipe. From there, a watertight back-up seal works to prevent leakage from back flow pressure. Depending on your retrofit drain, clamping rings may also be used to secure the drain to the piping.
