Leak test:

We perform a pressure test on the system which locates any leaks in the system. Once located we then effect the repairs.

This is an extremely useful tool as we can see inside a pipe, either above or below grade, to determine the condition. This is used on the entire flat roof drain installation.

REPLACEMENTS AND UPGRADES

In some cases, such as a reroofing project or in the case of broken roof drains, the existing roof drains need to be changed out or replaced. 

We install new, modern, efficient roof drains in the same location as those that we removed. In many cases we connect to existing piping. 

Again we recommend the use of our sump pans if it isn't and we work with your roofer. 

Effects of standing rainwater:  

Standing rainwater on a flat roof can cause extensive property damage and personal injury. Large pools of standing rainwater can cause a roof cave in. This situation can drive up maintenance and repair costs unnecessarily.   

Installing roof drains can be a FAST, EASY and VERY COST EFFECTIVE solution to this problem when compared to the cost of building up the roof, replacing an entire roof, resloping the roof or making EXPENSIVE structural repairs.  

Benefits of a Properly installed roof drains:

can help to mitigate further roof damage by very quickly getting the water off the roof whether the roof is replaced or not. They can stay in place as a permanent installation after roof repairs or replacement has taken place. They can prevent a roof collapse,  interior water damage and may help to keep your roof warranty in effect.  

All cast iron roof drains should have a roof drain pan that is sumped which means it's lowered.  A "sumped' roof drain can dramatically improve the roof drains' performance.
