Shingles frequently are not bonded to the roof where they overlap an adjacent shingle. Poor adhesion of the sealant strip in combination with cyclic thermal expansion and contraction along the long dimension of the shingle causes the lack of bond condition. Eventually, dirt and debris render the seal ineffective.

What are seals on shingles?

Sealing is mandatory in lengthening and preserving the condition of your roof. By sealing your roof, it becomes more durable to wearing out and tearing.
