A Guide to Buying Rain Gutters: What You Need to Know
A good rain gutter system is essential to protecting your home from water damage. A rusted, leaky rain gutter can do as much damage as a leaky roof.
But choosing a rain gutter system can be confusing. Gutters come in a variety of types, styles and materials. They can range from inexpensive vinyl gutters costing approximately $1 per foot, all the way up to ornamental copper gutters costing as much as $12 per foot.
Which type is right for you
Sectional vs. Seamless Gutters
Your first decision is whether to buy sectional or seamless gutters. Unless you are on a very tight budget, this should be an easy decision.
Sectional gutters are sold in pieces through home improvement retailers like Lowe’s The Home Depot. Sections are glued or snapped together to form the length of gutter you need. These gutters are inexpensive, but are notorious for developing leaks at the joints over time.
Seamless gutters consist of a single gutter that is custom-sized to fit your roof. The less seams you have, the less likely leaks will occur. As a result seamless gutters have become the most popular option for new homes.
Choice of Material
You can choose rain gutters made from a variety of materials. Which one is right for you?
Vinyl is the least expensive material, however vinyl has a low durability factor. It can become brittle and break in cold climates, and exposure to h3 sunlight will cause the vinyl to break down over time.
Aluminum is the most popular material for gutters. It is inexpensive, lightweight, rust-proof, and it is available in a variety of colors.
Galvanized steel is h3, durable and should resist rust for 20 years or more. The strength of the material makes it a good choice for homes exposed to extreme weather conditions.
Copper is one of the most durable gutter materials available. It is h3 and rust-proof. Copper will also acquire a greenish patina as it ages, making it a popular choice for period homes. A properly installed copper gutter system should last 75-100 years. If you prefer the shiny look of new copper, you can buy aluminum colored “copper” (Copper Penny Aluminum) that stays as bright as a new penny and will not patina over time.
Be careful when installing copper gutters and be sure to where appropriate gloves (Copper Wonder Gloves) to prevent discoloration of the copper from the oils of your skin as you handle the copper gutters and accessories.
K-Style vs. Half Round Gutters
Gutters come in either a trough shape known as a K-style, or in a U-shape known as a half round gutter.
K-style gutters are more modern and represent the majority of rain gutters found today. Half round gutters have a more traditional look, especially when made of copper. Half round gutters are a popular choice for people wanting a historical look.
Both styles will provide good drainage for your home, so the choice is mostly aesthetic.
In addition to the gutters themselves, you’ll need downspouts to carry the runoff and drain it safely away from your home.
Rectangular downspouts are typically 2x3 inches or 3x4 inches wide, while circular downspouts are typically 3-4 inches in diameter.
You may also need a splash block to catch splatter coming out of the downspout.
Sizing Your Gutters
Your rain gutters handle a lot of water. Consider this: one inch of rain falling on a 1000 square feet of roof amounts to 550 gallons of water flowing off your house. So how big do your gutters need to be?
Calculating the exact drainage of your gutter system is beyond the scope of this article, but a few rules of thumb can steer you to the right choice.
Your gutters should be sized based on the maximum rainfall you can expect, not the average rainfall. That means a house in Dallas, Texas, which can experience h3 micro-burst storms, actually needs a bigger gutter system than one in Seattle, Washington, where the rain is more frequent but less intense.
If your home has a steeply-pitched roof, it will collect more water as the wind blows rain onto your roof. A roof with a 45-degree (12/12) pitch will collect about thirty percent more rain than a flat roof.
Gutters can range anywhere from 4 inches to 8 inches wide, but 5 and 6 inch gutters are the most common.
If your home needs to handle intense storms, you can either install wider gutters or install more or wider downspouts to drain water away more quickly.
In addition to gutters and downspouts, it is a good idea to include gutter leaf guards in your gutter system. Gutter leaf guards help to keep out leaves, seeds and other debris that can clog your gutters.
These items have a variety of names, including gutter screens, gutter guards, leaf guards, and even gutter helmets. Each name describes a different approach to keeping leaves out, while ensuring a good flow of water into the gutter.
