The First Step in Roofing Shingling: Starter Strip Installation


Work across the bottom and one rake, then cover the other rake edge



At this point in the project, we have our new deck on, we have installed drip edge, eaves protection and underlayment, and we have prepared our valleys. Now, it is time to shingle the roof. In this episode, we'll show you how to properly install starter shingles.

Whether you are applying Architectural or Traditional 3-Tab Shingles, it is recommended that you read and familiarize yourself with the application instructions provided on the back of each shingle wrapper. One cannot go wrong if those instructions are adhered to during the installation of IKO shingles.

Although all types, styles, and sizes have a commonality to their application, each will have an individual installation feature that you must familiarize yourself with. Remember to always drive nails straight so that nail head is flush with—but not cutting into—the shingle surface.

Also, if nail heads are left protruding, they can tear into the shingle that is applied on top of them.


Starter Strip Application:

For the starter strip, we recommend using IKO’s Leading Edge Plus, a starter course that has already been cut to size. Each IKO Leading Edge Plus strip is perforated lengthwise for separation into two (2) shingles.

Note that IKO’s PRO4 Roofing System recommends that along with IKO’s singles, 3 accessory items be utilized to ensure roof performs to its maximum capacity. Starter Strips are a recommended component to the multi-layered system.

  • Take one IKO Leading Edge Plus strip and fold flat at perforation to separate.
  • Take one of the separated shingles and remove approximately 20 inches.
  • Install this shingle on the lower left corner of the roof deck, granule side up, with the factory installed sealant adjacent to the eaves. The shingle should overhang the rake edge and eaves by 1/4 inch – 3/8 inch. Fasten the shingle to the roof deck with nails located 3 inches to 4 inches from the eave edge and 1 inch in from each end.
  • Take the leftover 20 inch piece shingle. Rotate the piece and align it vertically up the rake edge with the factory installed sealant adjacent to the outer edge of the roof. The shingle should overhang the rake edge by a nominal 1/4 inch minimum. Fasten the shingle to the roof deck with fasteners located 3 inch to 4 inch from the rake edge and 1 inch in from each end.
  • Repeat these steps to the right lower corner of the roof deck.
  • Apply full-length IKO Leading Edge Plus shingles to the remaining eave edge of the roof deck. Install the shingles granule side up with the factory applied sealant adjacent to the eaves. The shingles should overhang the rake edge and eaves by a nominal 1/4 inch minimum.
  • Fasten the shingles to the roof deck with nails located 3 inch to 4 inch from the eave edge, 4 nails per shingle.

Make certain the first course of field shingle lies flush with the edges of the fastened IKO Leading Edge Plus. In this way, the sealant on the IKO Leading Edge Plus shingles will adhere to the first-course of field shingles and help keep them from lifting in high winds.

As a general rule, all shingles must be applied properly. We assume no responsibility for leaks or defects resulting from poor application or failure to properly prepare the surface to be roofed over, or failure to provide proper ventilation in accordance with Minimum Property Standards requirements. 

Review all applicable building codes, minimum property standards and requirements prior to applying these shingles using the application instructions found on the bundle wrapper.

Please use caution when stacking bundles on sloped roofs.
