Blacktop is a porous surface that can absorb water. When water that has been absorbed by your blacktop freezes and thaws, it can harm your blacktop. Sealcoating the surface delays the process so your blacktop will last longer, saving you money.

Cracks don't always form a clean, solid break. Routing opens the crack, creating a larger void for the hot, rubberized filler to adhere to the edges and seal the crack fully. If cracks are not routed, water can leak in and cause the deterioration of the base material.
