How To Build a Shed Ramp

Your Shed Ramp Will Probably Be Custom!

Adding a shed ramp to your shed is not hard but there are certain factors that may make the construction a little difficult.  For example if the ground in front of your shed is not totally flat your framing will be totally custom.  Perhaps you can do some leveling out of the ground in front of your shed so that you don't have to do a lot of custom wood framing. 

Some Shed Ramp Key Elements

• Your ramp should be framed and built with pressure treated lumber.  If you build it out of untreated lumber you'll probably be replacing it every 4 to 5 years just due to the weather rotting your wood out faster.
• If at all possible, you'll want the bottom ends to be resting on a concrete base or possibly concrete blocks, or even crushed rock gravel about 4" deep. 
• The support framing should be at least pressure treated 2x6's spaced 12" on center.
• The planking should be pressure treated 2x6's if at all possible.
• You'll want to use joist hangers if possible on the ends coming off your shed.
• Have a 'ledger' board to attach your ramp framing to.

Additional shed ramp support

Another very important factor to consider is placing support under the back end of your ramp.  Your shed may already have this as shown in the picture below.  Here you can see this shed was built with skids under the floor framing.  This will prevent any sagging of your shed floor from continous going in and out with heavy items like a riding lawn mower, etc.

The Back End Of Your Shed Ramp Should Be Supported Too!

Fasteners to use

Here's the fasteners I use to build my shed ramps.

• Simpson 2x6 joists hangers nailed on with joist hanger nails. (It's important to use galvanized joist hanger nails so they don't erode)
• I screw down the ramp decking to the support boards with exterior grade 3" screws.
• I use either galvanized lag screws or bolts to attach the ledger board to the outside floor framing of the shed.  Make sure to place them out of the way of where the support boards will be hanging off the ledger board.  You'll want to have 2 lag screws placed vertically next to the outside support boards and 2 in between each support board.
