Where do water and debris typically collect on a roof?

Water and debris typically collect at the eaves of a roof due to the natural flow of water down the slope. The eaves are the lower edges of the roof that overhang the walls of the house, and as rainwater or melting snow flows down the roof, it reaches this area first. Since the eaves extend beyond the walls, they act as catchment areas for runoff, which can lead to a buildup of both water and any debris that the water carries with it, such as leaves, twigs, and dirt.

This accumulation at the eaves is crucial to monitor, as it can lead to issues like water damage, rot, or ice dam formation in colder climates. Properly functioning gutters are often installed along the eaves to direct the water away from the building's foundation and prevent these potential problems.
