Step-by-Step Tutorial on How to Install Corrugated Metal Roofing on a Shed

How to Install Corrugated Metal Roofing On A Shed

1. Thoroughly clean the roof

If your shingles are relatively old, consider removing them. Also, remove any debris, sticking out nails and screws, or old adhesive from the roof. You may also insulate the roofing with plywood, building paper, and fiberglass batt if it’s possible.

Before insulating the roof, make sure to check if there are recommendations for adding insulation to the roofing metal you purchased.  

2. Install the bordering

Bordering is one of the essential steps you must not forget when installing metal roofing on a shed. It’s because edging helps your roof to drain water. Install the bordering at the end of the roofing with a hammer and 1-inch nails.

It’s important to note that bordering is not supposed to be an alternative to rain gutters. Both materials complement each other, and the edging should be attached above the rain gutters.

3. Install the corrugated metal roofing

Start placing the roofing from the edge of the roof with a hammer and screws. In terms of corrugated metal roof screw placement, it’s recommended to place the screws every 18 to 24 inches. The first screw should be placed at around 6 to 8 inches mark from the bordering.

Before screwing the screws, don’t also forget to add one washer for every screw. Afterward, use a silicone sealant to seal the panels tightly. When applying the sealant on each panel’s underside, place each panel on top of the shingle in a gentle manner. The silicone sealant will automatically spread when you slowly press the board.   

4. Install ventilation pipe

Look for the right spot on your roof to install a ventilation pipe. An ideal place would be the center part of the roof. You need to make a hole in your roof and use a circular saw and silicone sealant to attach the vent.

5. Add flashing

The last thing to install on your shed is the flashing. This material protects your metal roofing along with its shed against the water. You can place the flashing wherever there are two pieces of metal roofing. It would help if you used your hands to bend the flashing into a V shape.

Then, secure the flashings with washers and screws. Now, your shed has double protection against water.

That was how to install corrugated metal roofing on a shed. If you are confident to do this metal roofing installation on your own, you will obviously save a lot of cash.

Roofing a shed roof with metal roofing might cost you at least around $240 or could be more. Rather than spending money to hire someone to do the job for you, consider installing the roof yourself by following the tutorial above.
