Additional roof coating products, such as foam or coatings designed for seams, may be required underneath the main coating layers. [citation needed] Supplement coating products are used to reinforce damaged or leak-prone problem areas.
This enables a roof to be built without weak points. Since flashing is expensive to replace if it fails, copper's long life is a major cost advantage. [10] [11] Cold rolled (to 1/8-hard temper) copper is recommended for most flashing applications. This material offers more resistance than soft copper to the stresses of expansion and contraction.
