Gutters and downspouts are the silent heroes of your house. You never think about them and all the hard work they do. Until they stop working. Then the rain starts pouring over the sides, the downspouts are clogged up, and it's a big mess. Maybe it's time to have new rain gutters and downspouts installed. Let's take a look at what you may need to know.
Rain Gutter Materials
When buying new rain gutters, one of your first choices will be the material they are made from. Typical choices include aluminum, steel and copper. Plastic is available, but often not a good choice due to shorter lifespan. Wood, once the staple of gutters, is now becoming popular again, as properly installed and maintained wooden gutters can last for decades, sometimes longer than their metal counterparts. Regardless, you will need to make your choice based on your area (wetter areas with higher humidity can rule out steel, even though it's galvanized), your house's style and the look you are going after (copper is increasingly popular, though with a distinctive look), and price. Aluminum can offer the best balance of affordability and longevity. Copper is more expensive, but can last longer. Steel is cheaper initially, but can tend to rust if not taken care of well.
Take a good look at your situation before deciding - the decision will stay with you, good or bad, for quite some time.
Gutter shapes
Once you decide which material you are going to use, or perhaps in concert with the first decision, you will need to decide what shape of gutter you will buy. There are 2 major styles - half-rounds and the "K" style gutter (which can vaguely look like the letter K, but really is a kind of rectangular gutter). Also at this time, you will need to determine the size of the gutters. 4, 5, and 6-inch diameter styles are available, with 5-inch gutters being a good middle ground. If you have lots of trees in your area, larger sizes, like the 5 and 6-inch gutters, are a good choice to reduce clogging.
Attachment systems
So you know the material of your gutters and downspouts, you've got the shape dialed in. Now, how will you attach them to your roof? Duct tape? Hardly. In truth, the best option will be hangers. Spike-and-ferrule systems are available (basically a big nail with a spacer in the gutter itself) but they often pull out and generally don't last as long as hanger systems. There are a number of hanger styles available (hidden hanger, hanger and strap, crossbar hangers) but the truth is, any one of those will be a good choice. Which one will depend on your individual roof.
Downspouts
Even though gutter chains are becoming popular in some areas, the typical downspout will be 3x4 inch rectangular, or often a 3 or 4 inch round downspout. Larger is better here, especially if you live in areas with lots of trees.
Gutters and Downspouts
Remember that what you choose is going to be based not only on what you like, but what you can afford. Buy the best gutters and downspouts you can afford and generally you will be happy for some time to come. Just remember to clean them out periodically and they will keep taking care of you and your house.
