This Is How The Roof Drain Pan SSP System Will Look On Your Roof..

How To Install Roof Drain Pan SSP

  1. The first step is to cut the roof open between the joists so that the sump will sit down inside it.  This dimension is approx 14” square.   
  2. The second step is to cut away the roof material to the dimension of the sump pan flange. This is approx 24” x 24” square. Do this by setting the sump pan in the hole as in step 1.  Refer to the spec sheet for all dims. 
  3. Draw around the perimeter of the sump pan leaving yourself a little extra room, maybe add an extra ½”.
  4. Cut away the roof material. 
  5. Attach the roof drain to the sump pan and set the assembly in the hole.
  6. Now, secure the sump pan to the roof by screwing it directly into the roof joists using the perimeter holes.  The holes will be directly over the joists as long as they are 16″ on center.    
  7. That’s it. Now you can move forward with the waterproofing and plumbing work. 

One of it's best features is that it totally eliminates the need to build a labor intensive wood sump box which, by actual test, took 4x as long to construct.  This roof drainage system is truly FAST and EASY to install by the DIYer or the seasoned pro.
