## 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.

**Conventional Pattern**

The green areas on this 3-tab shingle show the typical nail placement on homes in areas with normal wind conditions.

## How To Estimate How Many Roofing Nails Are Needed

When you go to the store to buy roofing nails, you will be buying them by weight, not number. Containers of roofing nails will indicate how many pounds of nails it contains, not necessarily a number. Therefore, you need to know how much a nail weighs so you can estimate the number of nails youll be buying.

Knowing the total amount of shingles, youll need for your roof will allow you to calculate the nails needed. Youll use starter strips on the eave and rake ends, and any gable ends you might have. Youll add up the linear feet of starter strip shingles required.

If that is 300 feet, and we know that 16 shingles cover 50 feet, that means youll need 96 shingles. 96 x 5 nails mean youll need 480 nails just for your starter strip shingles.

For a 2000 square foot roof, youll need 20 squares of shingles. If you use standard 3-tab shingles, youll need 312 x 20, which equals just over 6,200 nails.
