Having dirty or clogged roof drain pipes can nullify the benefit of having roof drains. Unlike other types of drains, roof drains are exposed to the elements all of the time. In extreme cases, clogged roof drains can cause a roof to cave in.

Roof drain testing, inspection & certification

Often times an inspection of the storm or roof drainage system is needed prior to to a roofing project. This applies to a post construction also. A certification is required showing the before and after conditions. This will generally include several methods such as video inspections, water flow testing and pressure testing.

coring /scanning

When roof drains pass through walls that are concrete, cinderblock or brick, holes must be cored in order to allow for the roof drains to pass through to the outside of the building. All Tech Plumbing provides this service. Concrete scanning checks for embedded items electronically. This avoids cutting important structural items or electrical conduit. This service is done by our subcontractors.

Customer Testimonial

Quality Workmanship and Customer Care Never Go Out Of Style

This flat roof drain installation project was done in Southern California, USA. 

The roof drains were higher than the surrounding flat roof which was causing excessive ponding. Extensive property damage had been occuring. 

Adding new “sumped” roof drains resolved the problems. The savings in terms of cost of future repairs would range in tens to hundreds of thousands of dollars. 

ALL TECH Plumbing has the knowledge and experience to get the job done right.
