Ice and water shield in Monrovia

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 Monrovia and Los Angeles County

Monrovia has a roofing climate most of the country would not recognise: months of relentless UV with almost no rain, then the year's water arriving in a handful of concentrated winter storms. That pattern is harder on a roof than steady weather. Sun bakes the oils out of asphalt and hardens every rubber and sealant component until it cracks, and the failures sit there unnoticed through the dry months because nothing is testing them. Then the first real atmospheric river arrives and finds all of them at once, which is why leak calls across Los Angeles County cluster into a few weeks each winter. Low-slope and flat sections are the particular weak point here — they are everywhere in the local housing stock, they pond rather than shed, and their membranes are exactly what the UV has been degrading.

Monrovia has a population of about 37,931, and the housing stock here sets the pattern for what fails first on a roof.

Questions about ice and water shield in Monrovia

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.
