Gutters are an important feature for any home, especially if you live in an climate where rain or snow are common occurrences. Your gutters will help protect your home, from the roof on down, including the foundation and toperiary around it by directing any water away from the house.
The ancient Romans build massive aqueduct systems as well as gutters, construction methods that migrated to Great Britain in 47 A.D.. The idea of a water channel attached to the roof quickly caught on. Gargoyles served as decorative downspouts. In the 1700's cast iron became more readily available but it wasn't until the 20th century that rolled metal became available for use in residential buildings. 1960's ushered in the invention of seamless aluminum gutters when a machine was invented that could hold rolls of aluminum (gutter coil) at one end while extrudes formed a gutter at the other end. The pre-formed gutter could be cut to any length and custom fit to any home.
Today, approximately 70% of gutters are made from seamless aluminum and offered in a variety of colors, sizes and shapes with options like being a hidden gutter system. Some homes still use copper gutters.
Environmentally conscious individuals also use gutter systems as a way to collect and use the rainfall, hence the use of rain barrels.
That being said, some people may ask why water means trouble and why it is important to select the right gutter system for their home.
The trouble with water inside begins when water repeatedly collects around the foundation and eventually finds its way inside. Your home can only absorb so much of the moisture before it begins to settle against colder surfaces like your windows, the wood in your attic, and even your walls. Left unattended, this moisture can cause fungal growth and lead to expensive repairs.
The trouble outside? The water run off from the roof not only can seep into and damage the foundation of your home, but it can also cause soil erosion. The build up of water that is not absorbed or directed away will cause your foundation to compress and compact, as it carries the topsoil down through any limestone draining material laid during your homes construction, leading to more back ups.
A good gutter system can save you a lot of expense in the long run.
So what is involved in selecting your gutter system? There are some basics to begin with. The size of your roof area, how many places there are that you can channel the water through a downspout, as well as aesthetics and the maintenance involved in their upkeep.
Gutters can be either seamless - formed to custom lengths and offer joints that won't leak, but must be installed by a contractor. Zip hangers, spike, and ferrule hangers are common but continuous hangers are also available to ensure the gutters are free floating and not attached rigidly to your home. Sectional gutters, cut to specific sizes, are easier to install and are generally less expensive. However they can develop leaks over time, where the sections meet.
Downspouts come in different sizes and shapes, with a smooth or fluted face. Placement of them will depend on your home, roof size and drainage opportunities. If you live in an area with a lot of trees, wildlife, or wind-borne debris, a good gutter protection system will help ensure they do not get clogged, with the added benefit of lessening maintenance requirements.
You will want your downspouts to drain at least five feet away from your home. If you use outlet tubes, you will want to ensure that they are matched in size.
Another factor to consider is your roof pitch, especially if the pitch is steep or so low that it causes your roofing materials to significantly overhang the gutters and can cause overshooting.
Creating proper drainage is done by a good gutter system that involves the gutters and the downspouts. The gutters collect the water, the downspouts carry or direct it away from your home. Avoid diverting run-off into streets and sewer systems, which can further deplete ground water supplies, overtax city sewer systems and dumps lawn fertilizers, pesticides and pollution into rivers, lakes and oceans. Try greener solutions, like directing the water into your garden, or a rain barrel that can allow you to use it later, when drier temperatures require additional lawn watering.
If you live in an area where the climate gets cold, or there are frequent rainstorms, a lot of trees, or other conditions that can affect your gutter system will play a part in choosing your gutters.
Using an Ice Shield, usually a sticky tarpaper that goes under the first few layers of shingles, or flashing, can minimize ice build-up and ensure that there is no leakage when the wind presses the water back against the edge of your roof for any length of time. You can also help avoid Ice Dams by making sure you have proper insulation in your attic. This occurs when the heat inside your home rises, melting the snow and ice on your roof. If the ice build up is heavy enough it can actually cause your gutters to become loose or detach from your home.
A drip edge, a sheet of metal that fits under your shingles and guides the water away from your roof, is also an option.
Iossi is always glad to inspect your current gutter system and make recommendations based on their knowledge of the area and their experience with products that have worked well.
Gutters will periodically need to be cleaned and downspouts checked for blockages. This can be a time consuming, not to mention the percentage of falls from ladders that send a lot of business to local emergency rooms.
One way to limit these is by having a gutter protection system properly installed.
If you are cleaning your gutters yourself, please read any of the cleaning solution manufacturer's instructions carefully to avoid doing harm to yourself, your gutters or the environment. Never use an abrasive cleaner or strong solvents and always test the cleaning solution on a small section before applying it to larger areas.
You can minimize streaking by cleaning from the bottom to the top and then rinsing well with plain water.
If you are using a pressure washer, be sure to read all the instructions and hold the power washer straight at eye level. Do not aim the washer upward which can cause water to collect behind the siding and cause leaks, streaks, or water build up and decay. Set the pressure at a minimum of 1,500 PSI or a maximum of 2,400 using a 40-degree tip. Before using a pressure washer, check the gutter manufacturer's guidelines to see if they recommend that a pressure washer not be used.
If you only have moderate dirt build up, wash with clear water from a garden hose and a soft-bristled brush (a long handled car washing brush is a good choice).
For heavier dirt build up, wash as you would for lighter dirt, using a solution of mild detergent, usually 1/3 cup mixed with 1 gallon of water, or a tri-sodium phosphate solution (use recommended measurements from the manufacturer).
The presence of mildew can be eliminated using a mild detergent, tri-sodium phosphate, or sodium hypochlorite (5%) solution. Follow all solution instructions.
Caulking, tar and other substances: use mineral spirits in reasonable amounts and rinse immediately after with water.
Always employ correct safety measures when using a ladder.
