A home needs gutters to migrate the water away from the house. If water flows from the roof, it may cause damage to your windows and certainly to the foundation. It may also trickle down along the fascia boards (the board that runs along the roofline) and get into the ceilings. An inch of rain on a 100 sq ft roof area is about 60 gallons.
If you have gutter, make sure they do not leak along the seam and are not clogged with leaves and debris. Also, make sure the water coming from the downspouts is directed away from your home. One downspout for about every 30 to 40 linear feet of the roofline. There is a trend of using a rain train as a downspout but there must be a way to drain water from the ground.
New gutters come in a wide-ranging color scheme and are more durable than older gutters.
1. Aluminum gutters are lightweight, easy to install, and come in many colors. There are seamless types of aluminum gutters
2. Copper gutters are used on historic homes or industrial types of buildings. The seams need to be welded and tend to be pricey.
3. Vinyl is lightweight and cheaper in many colors. They are susceptible to UV sunlight and may crack in very cold weather.
4. Zinc gutters like copper do not need painting and will develop a patina over time. They are long-lasting but pricey.
