The roof perimeter uses details that differ from the main shingle field. Starter components should be part of a defined installation system rather than an unspecified allowance. Their role is easily overlooked when proposals focus only on the visible shingle brand.
What to do next
Ask how eaves and rakes will be detailed and which instructions govern the work. Compare perimeter treatment across bids. Keep the selected accessory information with the project records so the installed assembly can be identified later.
