Greetings from ca usa eric.
Roofing scupper box to french drain.
Poorly maintained and malfunctioning roof drainage systems can cause water to be concentrated or directed to areas that you don t want like a lower level unit or.
The best is to have a wide scupper 12 or wider so leaves and debris will wash through the scupper instead of clogging it.
The full flow capacity of a drain is not realized until the water reaches approximately 2 5 above the inlet in a four inch drain and 3 5 in a six inch drain.
Plus speedtite drains can be installed in minutes without any special tools helping to save time and labor.
The omg speedtite drain with built in vortex breaker technology is designed for improved flow performance that rivals traditional new connection drains.
Factors which affect proper roof drainage are deck slope drain size and placement of drains.
Scuppers are a very effective way to channel water off a roof.
Sealing the most critical part of your roof the draining area scupper hope you like it guys.
