Yes, according to hardibacker you can use roofing coil nails to install the hardibacker. If you are using a compressor and nail gun, then there will be no problem with getting the nails to sink. Make sure your compressor and gun are on the appropriate settings. You will want to place nails about every 5 inches. Any nails that did not sink the first time around...you can feel across the surface with your hand for any that are sticking up above FLUSH with the surface. Go ahead and use a hammer to tap down any nails that are sticking up. You want a smooth surface to lay the tile down on. If there are any sticking up, the tile setter will feel it when they lay the tile...and they will have to tap them down anyway.
