Valley leaks
Where two roof slopes meet
A proper inspection covers the covering, every penetration, all flashing runs, the roof space from inside, and the ventilation balance — then tells you what is wrong, what will be wrong within a couple of years, and what can wait. It is worth doing annually in storm-prone areas and before buying a property. A survey that only looks from the ground, or only from a drone, misses the attic entirely, which is where the most useful evidence usually is.
Pico Rivera has a roofing climate most of the country would not recognise: months of relentless UV with almost no rain, then the year's water arriving in a handful of concentrated winter storms. That pattern is harder on a roof than steady weather. Sun bakes the oils out of asphalt and hardens every rubber and sealant component until it cracks, and the failures sit there unnoticed through the dry months because nothing is testing them. Then the first real atmospheric river arrives and finds all of them at once, which is why leak calls across Los Angeles County cluster into a few weeks each winter. Low-slope and flat sections are the particular weak point here — they are everywhere in the local housing stock, they pond rather than shed, and their membranes are exactly what the UV has been degrading.
Pico Rivera has a population of about 62,088, and the housing stock here sets the pattern for what fails first on a roof.
It is a sales visit. That is not automatically bad, but the incentive is to find work, and a free inspection rarely includes attic access or a written report. A charged inspection you can hand to someone else is a different product.
Annually in a hail or storm-prone area, otherwise every two to three years, and always after a significant storm. The damage that causes leaks is usually invisible from the ground, which is exactly why it goes unnoticed.
