What this means for your roof
The starter course needs sufficient width for the specified headlap and fastening arrangement. Malarkey illustrates how starter dimensions relate to the first shingle course and explains additional starter requirements for its Windsor system. A generic starter choice should not replace the detail required for the actual shingle.
A useful question for your contractor
Ask which starter product is included and how it meets the selected roof system’s dimensions and fastening requirements.
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
