The functionality of home gutters
The main purpose of the gutters is to prevent water from reaching the building’s foundation and ruin it, the same with the roof.
The gutters are mounted on the roof line and house eaves. The gutters must be installed on a little slop so that the water will get away from the house through the downspouts.
If you don’t have a gutter system installed then water will just drop off the roof and onto the walls or foundation. This will greatly damage the walls and foundation and also cause leaks into the roof. If there is also heavy rain weather and the soil surrounding the house is saturated the situation is even worse. The soil surrounding the house may be eroded away from the foundation causing damage to the masonry.
