A canopy for the outside staircase - goodbye moisture

Annoying moisture often gets into the house and the basement area through the outer basement stairs. So that the walls do not even get wet and the building fabric becomes dilapidated, a roof should be placed over the staircase. In these instructions we will show you how you can solve this problem quite easily.

Cover the outside staircase step by step

  • Galvanized beam or post base
  • Galvanized joist hangers
  • Angle connector or angle galvanized
  • bar
  • Roof battens
  • Dowels
  • Screws
  • Clear corrugated cardboard / double wall sheets
  • Cordless screwdriver
  • Drill (€ 48.00 at Amazon *)
  • Ratchet box
  • Foxtail
  • drill
  • hammer
  • Folding rule
  • Spirit level
  • pencil

1. Mount the joist hangers and joist supports

The beam supports can be attached to the wall above the staircase with dowels and screws. Make sure that the height is sufficient so that a slope can be planned, otherwise the moisture problem will persist even after the roof is built.

The joist hangers are either screwed onto the slabs around the staircase or drive-in sleeves are used that have to be hammered into the ground. In no case should the wooden beams be placed directly on the ground, otherwise the wood will rot quickly.

2. Align the post

Line up the upright posts in the joist hangers or post bases and align them with one another. Take a long straight board and lay it out, then you can see on the one hand whether all posts are the same height and on the other hand whether one of the beams is slightly twisted. Then it would be difficult to attach it to its rafter, i.e. the roof rack.

3. Place rafters

In order to create a slope on the wall, the rafters must be beveled a little. You can make a small wedge out of the sloping piece that you saw off. Due to the inclined mounting, you need this wedge under the beam so that the beam lies neatly in its wall bracket, which is attached at right angles. Then connect the trailer to the post using an angle or an angle connector.

4th. Build the roof

You will need some roof battens that will be bolted across the whole structure. These not only hold the roof panels in place, they also stabilize the roof itself. You can then screw the roofing onto the roof battens. Treat the battens before processing, however, you will not be able to get there later.

Tips & Tricks You can of course also build corrugated sheets or a roof made of trapezoidal sheet metal for the basement staircase. But especially here you always have to struggle with the lack of light, so a transparent cover is more suitable.
