Pipe boot and vent leaks
Cracked rubber collars around pipes
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.
Harris County sits in Georgia's hail belt, where the spring storm line coming across the state tends to organise. Hail is the dominant roof killer here and it works slowly: the stone bruises the asphalt mat under the granule surface without breaking through, so the roof keeps water out for another season or two and then starts leaking from spots that were damaged years earlier. Add the summer heat load — Harris County roofs run extremely hot, which ages the shingle and dries out the sealant around every penetration — and the failures cluster around pipe boots, flashing and anything with a rubber component.
At the eaves it matters most in the north of the state, where freeze-thaw and ice damming are real. In valleys and around penetrations it is worth having anywhere, because that is about water volume rather than ice.
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.
