Mastering Roof Inspections: Asphalt Composition Shingles Part 26
The purpose of the series Mastering Roof Inspections is to teach home inspectors, as well as insurance and roofing professionals, how to recognize proper and improper conditions while inspecting steep-slope, residential roofs. This series covers roof framing, roofing materials, the attic, and the conditions that affect the roofing materials and components, including wind and hail.
Properly Driven Fasteners
Depth of Penetration
Whatever fasteners are used, they have to be of adequate length. Nails should penetrate a minimum of 3/4-inch into the sheathing, or just through the roof sheathing if its 1/2-inch plywood or OSB. Some manufacturers allow nails with less penetration above exposed soffits if extra nails are used.
Longer nails are required under certain circumstances, such as:
- when new shingles are installed over existing shingles
- when thicker shingles, such as high-end, multiple-layer laminated shingles, are used and
- when fastening hip and ridge cap shingles or ridge vent cap shingles. This is especially true when a continuous ridge vent is installed.
If you see many loose or missing shingles, be sure to check the method of fastening.
Nails and staples have to be driven to the proper depth.
Fastener Placement
Fastener placementis specified by manufacturers, and its often similar for similar types of shingles.
