What are some common materials that may require adjusting the stainless steel roofing coil nails depth?

Here are some common materials that may require adjusting the depth of stainless steel roofing coil nails:

Wood sheathing

Nails should penetrate through the sheathing but not protrude through the underside. Depth may need to be adjusted for different wood thicknesses.

Plywood sheathing

Similar to wood sheathing, nails should penetrate through but not out the other side. Plywood comes in different thicknesses.

Asphalt/composition shingles

Nails need to penetrate through the shingle but not completely through the roof sheathing. Depth depends on shingle thickness.

Metal roofing panels

Nails need to securely fasten the panels without penetrating completely through and causing leaks. Panel thickness affects depth.

Felt underlayment

Nails need to penetrate through the felt without penetrating too far into or through the roof sheathing. Felt comes in different weights/thicknesses.

Insulation layers

If nailing through insulation batts or rigid foam, nail depth has to be set to penetrate adequately into roof sheathing without puncturing completely through.

Roofing felts

Used under metal panels, depths should allow nails to penetrate through felts without passing through roof deck.

So in summary, the thickness and number of roofing layers needs to be taken into account when setting stainless steel coil nail depth. A nail depth guide can help get the right setting.
