Avoid any water dripping from the roof by using Rain Diverters


When rain falls on a pitched roof, it will run down the shingles or tiles and fall to the ground below. Most roofs have an overhang over the wall so that any rainwater does not run down walls and instead falls directly on the ground below. Rainwater falling of roofs can be a nuisance especially at doors, and this can easily be prevented through the installation of rain diverters.

Rain gutters

It is always best if you can install gutters at eaves level, and divert the rain through down take pipes that can then lead to a drain. However, this can mean extra costs for the gutters, pipes and their installation. Gutters can also add to maintenance problems, as they do tend to collect debris and leaves, that can then block the gutters and prevent them from functioning.


You need to always ensure that gutters are clear and efficient in their function of clearing rainwater. They can also lead to the formation of ice dams that can then create conditions that lead to roof leakages. Instead, a roof with sufficient overhang can work just as well to deal with the rainwater falling on the roof, and prevent all other problems like blocked gutters or ice dams.

DIY : How to make a Rain diverter

Rain diverters are specially made metal flashings made from aluminum sheets and are readily available in standard lengths in most home improvement stores. If you are adept at DIY skills, you can even make the rain diverter yourself from sheet metal. All that you need is sheet aluminum and two straight 2 X 4 timber pieces that will help you to bend the aluminum sheet to the required shape to form the rain diverter. You would require other tools like clamps, a mallet, preferably rubber, a knife or cutting tools, and a straight edge.

Go down to your local building supply store and ask them for sheet aluminum. This is available in rolls. The sheet you buy must be 8 inches wide and at least two feet longer than the door width that you need to cover. Sheet aluminum can be cut with scissors, but this can cause it to warp, and make for uneven cuts. It is far better to use a utility knife and a straight edge to get a smooth and accurate cut.


​Measure the width of the door you need to cover so that you can decide the length of the rain diverter that you need to make. Your diverter must extend at least a foot on either side of the door, if not more. The aluminum sheet must be laid on a firm and flat surface before you cut it to the required dimensions. Use the knife to score along the straight edge a number of times, so that the sheet can then be bent easily. Worrying the sheet many times, by bending it will then cause it to break and give you the desired length. Use the same method to cut in the other dimension, if needed, till you have a strip of the required length (at least two feet more than the door). Your aluminum sheet is now ready to be formed into the required shape of a rain diverter.

Now the sheet of aluminum must be placed between the two timber pieces in such a way that 2" of it is protruding. Make sure that the timber 2X4s are straight and lined up with each other. Use the clamps to make the assembly of sheet and timber a firm one. Now, push down the protruded part of the sheet with your hands, until the sheet forms a right angle. The mallet may then be used to see that the bend is properly finished. A block of wood can help you to do this easily. You can then unclamp the assembly as your diverter is then ready for installation.

Now that you have to work on the roof, make sure that you have a proper ladder or scaffolding that will enable you to work with the required degree of safety. It is always a good idea to have someone on the ground to help maintain the stability of your ladder or to hand you any needed tools. Your rain diverter will collect the rain and allow it to run off to the sides. and you can bend the rain diverter in the center slightly if you want this to drain out on both sides.

It is now time to break the seal of the shingles that are positioned over the doorway that you are wanting to protect. Do this carefully, as you are not wanting to completely dislodge the shingle, but just need to create enough of a gap that will allow you to slide the rain diverter below the shingles. Now that you have loosened the shingles, slide the 6 inch part of your diverter under the row of loosened shingles. The bent 2 inch part will stand up above the shingles and act as a barrier to the rainwater coming down the slope of the roof above. See that diverter is sloped towards the one side or both sides as you have decided. Now you can start the process of fixing the rain diverter firmly, by using roofing nails that will hold the diverter and the uplifted shingles firmly. Now finish the work by adding roof cement over each nailhead that can help to seal it to keep out water and also help in holding down the shingles. Run some water down the roof with a garden hose or other means to make sure that your rain diverter is working as it is required to. Your helper below can confirm that this is so.

Repeat the process for any other doors that you have that allow you entry and exit from your home. You can also install similar diverters at all other spots along the perimeter of your roof that you feel need such attention. Rain diverters will normally not require any maintenance, but during your annual maintenance of roofs, just see that the diverter is firmly held down and has not accumulated any dirt in it.


Factors to consider when choosing a snow removal rake

1. Length

When choosing the right rake, it is vital to consider the height of your roof in relation to the length of its handle. Snow removal rakes are extendable, so you should look at the maximum extension length of the handle.

However, most rakes are not very useful when extended to their full length; hence you should choose one that you don't have to stretch to its full extent to reach your roof.

2. Design

​The design of the rake significantly affects its comfort ability and effectiveness. It is better to choose a rake with a design that offers a good grip and doesn't get stuck on your roof edge. Also, rakes can cause damage to your roof shingles; hence you should choose one that won't damage your roof.

Curve-bladed and wheeled rakes are the best at protecting your roof.

3. Weight

​The weight of the rake has great significance on the level of comfort it provides and proper handling. Heavy rakes are very uncomfortable to use and also make you fatigued. You should go for a lightweight rake, but be sure to check the materials it is made of as a material like wood breaks when subjected to a lot of weight.

4. Durability

​Nobody wants to see their money go down the drain; hence you should consider buying a rake that doesn't break or rust. Rakes with aluminum handles and polyethylene are the most durable as they are not susceptible to rust and breakage.
