El Monte designs to a 95 mph gust, and wind is what drives rain into a deck edge.
El Monte uses a design wind speed of 95 miles per hour as a three second gust, at Exposure B. That number matters more for waterproofing than people expect. Rain falling straight down is easy to shed. Rain being pushed sideways at speed goes uphill into laps, under flashing, behind a railing post and through the gap at a door threshold, all places a deck surface alone was never going to stop.
So the parts of the job we take most seriously here are the ones you cannot see afterwards: how the membrane turns up a wall, how it terminates at a threshold, and how it is sealed around anything that penetrates the deck.
The city sits between the San Gabriel and Rio Hondo rivers, and around 60 percent of occupied housing is rented, so a large share of the work is walkways, stairs and balconies on multi unit buildings.
