Ice and water shield in Lincoln

Ice and water shield is a self-adhering rubberised membrane applied at the roof's most vulnerable points — eaves, valleys, and around penetrations — where ordinary underlayment is not enough. It seals around fixings rather than just lying under them, so water that gets past the covering still cannot reach the decking. It matters most where meltwater backs up behind ice at a cold eave, and in valleys where water volume is highest.

Why roofs fail in Lincoln and Logan County

Lincoln gets the full range — freeze-thaw cycling through winter, severe convective storms with hail and straight-line wind in spring and summer, and enough temperature swing between them to work every joint on the roof loose. Freeze-thaw is the quiet one: water finds a hairline gap in flashing, freezes overnight, expands, and opens it slightly wider, repeating through a Logan County winter until a joint that was watertight in October is leaking by March. Spring brings the loud damage, and derechos have put straight-line wind through this region at speeds that take ridge caps and whole shingle courses. Housing stock here is older than average, which means a lot of roofs where the flashing has already been through several decades of that cycle.

Lincoln has a population of about 13,288, and the housing stock here sets the pattern for what fails first on a roof.

Questions about ice and water shield in Lincoln

Do I need this where I am?

At the eaves it matters most anywhere that gets freeze-thaw and ice damming — the colder the winter, the more it earns its cost. In valleys and around penetrations it is worth having in any climate, because that is about water volume rather than ice.

Can it be added to an existing roof?

Only where the covering comes off, since it bonds directly to the decking. It is a re-cover or major-repair item rather than a retrofit.
