Roof Drain Replacements

Replacing or upgrading your roof drains can save thousands of dollars in future repair costs. Further, installing high quality sump pans will lower the roof drain and prevent standing rainwater on the flat roof, the main cause of roof damage. However, that's only if the work is done right.

Experience and product knowledge

Installing new roof drains is one thing as there are no existing materials to be removed. Replacing roof drains is another matter entirely as the installer has fit new materials into the existing drainage configuration.

This task requires a higher level of experience and expertise and should only be undertaken by a contractor with proven skill with this type of work. Failure to do so could result in extensive property damage.

Roof Drain Cleaning

  • Stoppages can occur in the roof drainage piping system that is within the building or the piping that is installed outside the building, and above or below grade. 
  • All Tech Plumbing will handle all aspects of the roof drainage system

Roof Drainage System Inspection & Certification

Our roof drain pre-testing and post-testing service is performed before the start of a flat roof replacement project and after it's completion. This testing procedure checks for stoppages and defects in the plumbing system and the results can be certified. This service is generally performed with roofing consultants and their clients on government roofing projects but can be performed on private roofing projects as well.  

Video Pipe Inspection

Here is modern technology applied to the plumbing trade. Using our color camera we are able to inspect any piping, whether above or below ground, piping for defects before we ever break concrete or lift a shovel. Then using a state of the art locator, we precisely determine the depth. This results in major cost savings for our clients

Concrete Coring

A Definite Must!  This is vital service applies to our projects where the building has concrete or cinderblock walls and the new roof drain pipes need to pass through the wall and get connected to the roof drains

Concrete Scanning

We scan the concrete prior to core cutting the surface. This checks for embedded items electronically and avoids cutting important structural items or electrical conduit.
