A scupper is a type of roof drain that is used on flat roofs to allow water to flow off and drain properly. This type of drain is especially useful in areas where there is heavy rainfall or snowfall. It helps to prevent water from pooling on the roof and potentially causing damage. Installing a scupper drain on a flat roof can be a relatively straightforward process. With the right tools and materials, you can complete the job in just a few hours.

Getting the roof ready
You should clean the roof surface and make any necessary repairs before installing the drainage opening. It will ensure that the scupper drain adheres well to the surface. If there are any cracks, chips, or gaps in the roof, fill them with roofing cement. Next, apply tar paper to the roof to act as a barrier between the roof and the drianage opening.
Prepare the Drain
The drain must be properly prepared before the scupper drain can be connected. If you already have a drain in place, make certain it is clean and free of debris. If you need to install a new drain, make sure you have all the necessary materials and tools, including pipes, fittings, and a drain grate.
Install the Flashing
The flashing surrounds and protects the drainage opening against water damage. Measure the drainage opening´s size and cut the flashing accordingly. Then, attach the flashing to the roof using nails or screws. Make sure to attach the flashing securely to the roof, as this will help to keep the scupper drain in place.
Attach the Rubber Gasket
The rubber gasket will provide a tight seal around the scupper drainage and prevent water from seeping through the gap between the drainage opening and the roof. lPace the gasket around the scupper drain and attach it to the roof using silicone caulk.
Install the Scupper
Place the scupper drainage into the opening in the flashing and secure it in place using screws. Make sure the scupper is level and that it sits flush against the roof.
Connect the Scupper to the Drain
Once both are prepared, it´s time to connect the scupper drainage to the drain. Begin by cutting the necessary pipes and fittings to size. Then, connect the pipes and fittings together to form a pipeline from the drainage opening to the drain. Conect the bottom of the scupper drainage to the pipeline that leads to the drain. You can do this by using a flexible coupling or a flexible piece of pipe. This will allow the scupper drainage to move with the roof and prevent leaks.
Caulk Around the Scupper
After the scupper drain has been installed, it´s imperative to caulk around it to ensure a watertight seal. Use silicone caulk to fill any gaps around the drainage opening and the flashing.
Install the Drain Grate
Install the drain grate over the drain to prevent debris from entering and clogging the drain. Make sure the grate fits securel yand is level.
Test the Connection
Finally, test the connection between the scupper and the drain to assure it is working corectly. You can do this by pouring water into the scupper and checking to see that it flows into the drain.
By following these steps, you can connect the scupper to the drain and ensure that the water is flowing properly.
If you are unsure about any aspect of the connection process, it may be a good idea to consult with a professional plumber or roofing contractor. They can provide you with advice and assistanceand ensure that your drainage opening and drain are installed correctly and safely. This is especially indispensable because improper connection of the drainage opening to the drain could lead to water seepage or pooling, which can cause structural damage to your home or property. Additionally, the drain needs to be properly vented to ensure that the water can flow freely an d without any blockage.

Make sure to choose a scupper that is suitable for your roof and the weather conditions in your area. Different types of scupper drains are designed for individual types of roofs and climates, so it´s wise to choose one that will work well in your specific situation.
It´s also critical to follow all local building codes and regulations when installing a scupper. Some areas have specific requirements for roof drains and other roofing components. Therefore, make certain to check with your local building department to ensure you aref ollowing all necessary guidelines.
Regular maintenance is imperative to keep your drainage opening functioning correctly. You should inspect your scupper drainage regularly and clean it of any debris that might clog the drain. You should also check the flashing and caulking around the scuper drainage to be certain they are in proper condition and that there are no leaks.
Maintaining your scupper drainage is like changing the oil in your car – necessary for continued performance, but often overlooked until it´s too late. Taking the time to do regular maintenance will help you keep your scupper drainage in good condition for years to come.
What is the Difference Between A Roof Scupper and A Drain?
A roof scupper drain and a drain are two various elements of a roof system. A roof scupper drain is an opening in the exterior wall or parapet wall of a building that allows water to drain off the roof. They are usually located at the edge of the roof, and sometimes at the corners of the building where two wals meet.
A drain, on the other hand, is an enclosed system of pipes and a catch basin installed within the building which drains the water away from the roof. The water is then usually directed to a stormwater system or a sewer line. Both elements are essential components in ensuring proper drainage of a roof system, and both should be correctly sized and installed by a professional to ensure that they are functioning correctly.
How Effective Is a Roof Scupper?
The scupper drain is designed to quickly move large volumes of water away from the roof surface, while also allowing water to be directed out from the building envelope. The effectiveness of a roofdrainage opening depends on its location, size, and material select ion. For flat roofs, scuppers should be located near the perimeter of throof. They should be large enough to handle the volume of water that will be draining off the roof. For steep-slope roofs, drainage openings should be strategically placed to direct water away from the walls and windows.
What are the roof scuppers made of?
For material selection, scupper drainages should be made of corros ion-resistant materials such as copper, aluminum, or stainless steel. Standard roof scupper drains are available inboth rectangular and round shapes.
A multi-level roof drainage opening is a popular option that allows for water to be diverted at different elevations and is commonly used when the roof slope is too low for gravity drainage. Bonded roof scupper drains are a great choice for areas that may ex perience high winds, as the bondde seal helps to block wind from entering the building.
What is the Cost Of a Roof Scupper?
The cost of installing a roof scupper drain varies depending on the size, complexity, and material used. On average, the cost of a roof scupper will range from $100-$200 dollars. It is salient to take the time to research individual materials and sizes to ensure the best fit and the highest quality product.
Profesional installation is highly recommended to ensure the scupper drain is properly installed and functioning properly. Ultimately, a roof scupper drain is well worth the investment to protect the integrity of the roof and building structure.
You can install a scupper on a flat roof pretty easily, but it is critical to take the necessary precautions and folow the steps carefully to ensure proper installation and avoid roof damage. The process is similar to putting together a piece of furniture from IKEA – if you don´t follow the directions correctly and take the time to understand the instructions, you can end up with a final product that´s full of mistakes. But unlike IKEA furniture, a roof can´t be returned for a refund!
