Fixing a leaky roof drain

Fixing a leaking drain is more than important as you will avoid any damage to your house. As sooner you fix the leak, the more money you will save.

Some of the tools and materials needed for the job are:

  • Wire brush
  • Screwdriver
  • Binoculars
  • A-frame ladder
  • Sheet metal
  • Roofing cement
  • Coarse sandpaper
  • Caulk
  • Replacement parts and fastenings
  • Tape measure

Damaged area

Examine the entire surface of the roof drain and locate the damaged area.

Be careful when you get on the roof to prevent any accidents. You can locate the leak easier if it has affected any parts of your home.

After you have the affected area, you should see from what material the guttering is made. You should use the same materials for the repairs.


Determine whether you can make any repairs or that you should replace the whole area. Consider the extend of the damage. It’s better if you replace a damage section because you will prevent any future repairs.


Clean away the debris if you plan on patching the surface. Use a wire brush and water to clean it thoroughly. Dry the area and use some sandpaper to rub it. Use some roofing cement as an adhesive. Cover the hole with cement. Also use an additional piece of metal.

Replacing parts

If the damaged area is large and it has caused a significant amount of damage, replace the entire section of the roof drain. Clean the drain with a wire brush at first. Pull away the damage piece or pipe. Scrub any old adhesive from the mouth of the remaining sections.

Before fitting the new piece, apply several beads of caulk to one end of the replacement section. Tighten the fixture only after you have ensured that they are properly fitted.
