Some homeowners want their residence to follow the latest style, and, therefore, their home-of-choice has a flat roof. Unfortunately, such a structure lets the rainwater accumulate in spots. Thus, it creates the need for taking precautionary measures, such as the following.

Interior drains

These operate in the same manner as the drain in a shower. So, how does a homeowner know where to place such an interior drain, when there is no overhanging showerhead? It belongs in a location where water has been known to pool. Like any form of plumbing, interior drains should not be allowed to clog. Thus, it helps to keep track of what items get washed into any drain that sends rainwater into an interior pipe.


These work well, if a roof is not entirely flat. Like the gutter that has been placed on a home with a slanting rooftop, these gutters rely on gravity’s ability to pull any item in a downward direction. Roof repair service in San Mateo knows that each of them collects the raindrops and sends the pooled drops into a downspout. In terms of installation, gutters cost less than interior drains, but each of them demands more work. At least that is the case in the event that a homeowner’s concerns include the functioning of the home’s existing drainage system.


This square opening at the roof’s edge manages to scoop up whatever water falls from the sky, and lands on the rooftop. After it has become full, it lets the collected liquid (water) out. If a home with a flat roof has been built in a region with 4 distinct seasons, a scupper might be the best type of drainage system. It would appear capable of handling a fair amount of snow. Of course, it would need to have a substantial bottom, if a snowfall had been especially heavy.

Unfortunately, scuppers could also get viewed as a source of entertainment, if small children lived in the home that relied on a scupper’s ability to collect and release water. The pool in the scupper, the one that had formed from the rainwater would look like a place to go fishing. A young child might want to explore for fish, using an improvised fishing pool. In addition, there is no information on the depth of the water that forms a pool in a scupper. Would it ever get deep enough to pose a threat to a small child? The parents of small children might feel obligated to ask that specific question.

Outside of that one possible disadvantage, there are no reported drawbacks to reliance on one or more scuppers. Every single one of them rarely becomes clogged. In other words, none of them require a great deal of maintenance.
