How to Install Seamless Steel Siding

What You'll Need
Tape measure
Foil underlayment
Staple gun and staples
Chalk line
Nails (two inch galvanized)
Corner caps

Seamless steel siding is an alternative to the more commonly used vinyl or aluminum sidings. If you are doing installation on your own, one of those may be easier to tackle. However, no project is impossible if you have the right guide by you side. Consider the instructions below. 

Step 1 - Take Measurements

Measure all of the walls of your home that will be covered with siding. You need to measure everything, including gambrel walls, gable ends and dormer sides. After doing this, subtract the size (the square footage) of the windows and doors, including the garage door and any sliding glass doors. Now take that total and add 100 to it. This should give you the correct total amount of square feet of steel you will need. 

Step 2 - Prepare the Wall for Siding

Prepare the area where you will install the siding. Pound in any protruding nails and clean off old paint. Replace rotting wood, old putty, caulking, etc. Make sure to tie back your plants, and if there are uneven spots on the house walls, make sure to even them out with shims. 

Step 3 - Adhere the Insulation

Now, attach the foil underlayment to the area that you will be installing the siding. This will serve as insulation for the siding. Staple this to the walls. Place the underlayment at all corners and edges of the walls. Make sure to have the foil overlapping the sides and end joints by about two inches. 

Step 4 - Chalk the Walls

Make a chalk line from one end of the house to the other end. This will give you an idea of where you will be placing your starter strip. This will help be your guide on keeping the siding straight as you hang it. You should also mark from the eaves down to the bottom and measure from under a window to the bottom of the house as well. 

Step 5 - Hang the Siding

Now take a nail and pound it into and through the already pre-made hole. Make sure that it is not nailed in tight, just snug enough to hang the siding. You do not completely nail all of the siding into the walls. The siding actually has to have a chance to move with the changes in weather. If it were to be nailed in too tight, it will not be able to move the way it is suppose to when necessary. 

Use your 2-inch nails to hang the siding. Make sure that you nail the siding into every stud in the wall, no more than 16 inches apart and make sure that they are never closer than six inches. 

Step 6 - Install the Starter Strip

Take the starter strip and place it all around the house where the chalk line is. Take a level and make sure that the starter strip is even especially at the corners. This strip will be what helps you hang the siding evenly.  

Step 7 - Hang Siding on Other Walls

Complete the installation on one wall first. Make sure that you overlap the different pieces of siding by at least 2 inches. Once you have finished this wall, go to the adjacent wall and begin attaching the siding here. Make sure to leave a gap that is ¾-inch of that end because you need space to install the corner caps. 

Step 8 - Attach the Corner Caps

After you have all the siding attached, you will need to take the corner caps and attach them by slipping the bottom flanges under the ends of the siding. Then just push your corner cap up and make sure to press into place, making sure it has a tight fit. Now secure the ends of the corner caps with your 2-inch nails.
