Why your shed needs guttering.

Firstly do Sheds need Guttering?

In simple terms, Yes they do! The U.K and rainfall go hand in hand I'm afraid. As I'm writing this in the middle of our summer I'm pleased not to be outside as the rain is cascading off the nearby rooftops!

Yes, but do I really need gutters?

If you have a building on your property like a shed, greenhouse, gazebo, guest house or freestanding garage, look for these obvious signs that might be a warning you need a gutter system in place.

  • Soil Erosion

When water is allowed to flow from a rooftop, it can do damage to the nearby soil and landscaping around the shed. While water is good for plants and earth, too much rainwater cascading down from a garden shed roof can saturate the ground, moving soil away from the foundation and the roots of plants and shrubs. Watch out for bald spots, exposed roots and sediment where it shouldn’t be such as some distance from the accessory building or on the pavement.

  • Interior Water Damage

Another sign that your garden shed or workshop needs gutters is interior water damage. Water dripping or draining inside a building not only looks bad (stains and streaks) or endangers possessions, it can adversely impact structural integrity.

For maximum functionality of an accessory building, consider adding gutters to your shed, workshop or greenhouse. Gutters and mini-gutters designed especially for popular types of backyard structures might be the ideal solution.

  • Rotting Foundation

Unchanneled rainwater falling directly from the roof to the ground can pool and/or splash. Pooled water at the base of an accessory building can seep in, around and underneath the foundation, making it unstable. If the shed is made of wood, timbers at the base of the structure can become rotted. Splashed water landing on the sides of a shed often promotes the growth of mildew and mould.

  • Standing Water

Water pooling in front of a garage door or a shed indicates it isn’t draining away properly. Rainwater should not be allowed to collect anywhere around the perimeter of the structure. A gutter system that includes at least one downspout will ensure that water is drained away from the foundation.

Ok so you need a guttering system in place, you've bought the materials and now your DIY skills are going to be put to the test.

If you plan to fit the gutters yourself have a read of the tips and hints below, they may well save you time and embarrassment!

1) Accurately Measure Your Roof

Before you learn how to install gutters, you’ll need to accurately measure your roof. Gutter systems must run the entire length of your roof. Carefully climb up a ladder and use a measuring tape to get an accurate measurement. This will tell you how much gutter you’ll need to purchase. Likewise, this measurement will also tell you how many downspouts you need. Lengths over 40 feet will require you to install two downspouts, one at each end of the gutter.

2) Mark Points of Downward Slope

Gutters may look like they are attached completely straight, but they are actually following a downward slope. This is to allow water to move straight into the downspout and prevent water from pooling. Use chalk to mark the fascia to indicate where the downward slope will be. For every 10 feet, you’ll need to lower the gutter by ¼ of an inch. For example, a 30-foot gutter will have its drops at ¼ inch, ½ inch, and ¾ inch to ensure proper flow of water.

3) Cut Your Gutters Based on the Slope Markers

In many cases, you’ll end up purchasing gutters that are a little too long to be mounted on your home as-is. You’ll have to cut your gutters to match the length of your roof. Use a hacksaw to carefully cut your gutters into the appropriate lengths based on the measurements you had taken beforehand. Always cut your gutter on a flat surface to ensure you get a clean and straight cut with a hacksaw.

4) Mount the Supports and Your New Gutter

Start by attaching the gutter’s fascia brackets by drilling a ⅛ inch pilot hole. These pilot holes should be located at the downward slope points mentioned earlier. After you’ve made the pilot holes, use ¼ inch stainless steel lag screws that are at least two inches long to secure the fascia brackets into place. If you are having trouble getting the screws in due to the hardness of the fascia, try applying soap to the stainless-steel lag screws. Once everything is in place, lay your new gutters into the fascia brackets.

5) Attach the Downspout

When all the gutters are put into place, you’ll need to attach the downspout. Simply screw the actual downspout onto the gutter outlet you’ve attached earlier. When attaching the downspout, make sure that the endpoints directly towards nearby drainage to avoid flooding in your garden, lawn, or driveway. Once everything has been attached, apply a heavy bead of sealant to the connection seams and allow this to completely dry overnight to ensure stability.
