Have you ever been to Disneyland? It never ceases to amaze me how they engineer the parking to meet the every-changing demand and flow of traffic. And even if you leave at the end of the fireworks display during the Christmas season, you never have trouble leaving the garage and getting back to the freeway.
I’ve also been to two other stadiums in Orange County, not to mention names, but their exiting is a more frustrating experience.
Unlike high-pitched residential roofs, commercial flat roofs have an exiting challenge. Water will land on your roof. Whether it’s rain, condensation from fog, or condensation from your roof-top mechanical units, that water should never sit on your roof and collect (ponding). It needs to exit, slowly, in a single-file line.
Proper Roof Drainage
One of the obstacles preventing efficient water drainage is clogged roof drain wells. In Southern California we’re known for unseasonably warm temperatures. This is due to the Santa Ana winds.
We like the warm weather, but do we think of the debris that has now been blown onto our roof? It’s likely that debris has collected in the corners where roof drains are located. This is one of the reasons why preventive maintenance (annual, semi-annual, or quarterly) is so important. Those drain wells should always be clear, ready to receive rain.
If your roof isn’t properly sloped to engineer the Disneyland experience of exiting, then that can be solved by installing crickets to redirect the water. Equipment is often added to the roof long after it was designed. Unfortunately, it’s not always placed in the most optimal spot. It can actually impede drainage. The good news is that can be corrected.
