FLAT ROOF DRAIN INSTALLATION:
VIDEO OVERVIEW: This flat roof drain installation was done by our roofing contractor client using model SSP roof drain sump pan and model 854N Frank Pattern roof drain on a TPO roof.
It shows the basics of how to “sump” (lower) a small cast. iron roof drain with before, during and after shots of the actual installation on a TPO roofing system.
The roofing contractor purchased this system from www.roofdrainpans.com after reviewing all of the other systems that are available on the market. None were specifically designed to “sump” a cast iron roof drain.
The system went together fast and easy leaving the new roof drain as the lowest point on the flat roof. The heavy duty, quality materials along with an excellent high quality roofing job means that this roof has no major ponding rainwater issues and will provide many, many years of trouble free service.
This is the FASTEST and EASIEST patented system on the market for lowering roof drains on a flat roof.
This system will dramatically improve the performance of your roof drain!
Watch this video to see exactly how this roof drainage system goes together. https://youtu.be/VAhu0jqAOjs
“Sumping” commercial flat roof drains is vital whether you are lowering existing roof drains or a doing a new roof drain installation using new commercial flat roof drains.
How do you install a roof drain? Here are the roof drain installation instructions…
STEP 1. Find the low spot on your commercial flat roof:
a. This will generally be very obvious as debris settles in the lowest spots and the area will be discolored.
b. If the flat roof is dry and you really can’t tell, put some water on it and will it will gravitate to the low spot(s). You can also use a straight edge or a string. We’ve even used a tennis ball which rolls to the low spot.
STEP 2: Due diligence. You need some basic info before so you can buy the correct roof drain.
a. You need to know which direction and how far apart your roof joists/rafters are first. On wood roofs, they are either 16″ or 24″. On concrete and steel roofs, they are further. Look in the attic space unless it’s open beam and measure. If you have no access, you will need to find blueprints or do a test hole. This is VITAL.
STEP 3: Buy your roof drain and sump pan:
a. If your joists are 16″ apart, you can use an 8-1/2″ diameter roof drain. If your joists are 24″ apart or more you can use a 12″ diameter or 15″ diameter flat roof drain. I would not use a 12″ diameter roof drain between joists that are 16″ as the sump receiver or drain pan may not fit. You do not want to modify any structural members such as cutting the joists to get the roof drain to fit.
b. Next buy a roof drain pan, either a sump receiver or a custom fabricated roof drain sump pan from (www.roofdrainpans.com). The sump receiver does not have a true “sump” or lowered section and can cause further ponding, whereas the roof drain sump pan does. Getting the roof drain as low in the flat roof as you can is VITAL for excellent flat roof drainage and to prevent further ponding
Step 4: Installation…
a. Cut a hole in the flat roof between the rafters big enough to receive the roof drain pan or sump receiver.
b. Attach the roof drain to the roof drain pan. see the video or manf drawings.
c. Set the assembly on the flat roof with the “sump” section directly in the hole. Structural modifications should not be needed.
d. Secure the flanges on the roof drain sump pan to the joists with nails or screws on the two sides that straddle the roof rafters. (not supplied. Stainless steel screws work great)
Step 5: Plumbing and roofing.
a. It is always recommended to have professionals handle these tasks.
