Why Shingles Are Not Enough?
Shingles are designed to protect your roof from rain and snow, but they are not completely effective in preventing the movement of moisture from the roof deck upwards. Wind-driven rain can be blown under the shingles, destroying their integrity and depositing water into your attic. Freeze and thaw cycles can allow the ice dams to force water back under the shingles. The eaves of your roof are most at risk, however, the valleys and around skylights, chimneys, and other flashing areas are also in danger.
Can ALCO SHIELD be applied over felt?
No. Felt will act as a bond-breaker to the substrate. ALCO Shield is intended for application directly to the structural deck.
How long can ALCO underlayments be exposed?
ALCO underlayments are not meant to be left permanently exposed to the sun. In general, the membrane should be covered with the final roof covering as soon as possible.
Does ALCO SHIELD go over or under drip edge?
It is over on the bottom-gutter edge (eave) and under on the side/rake/gable end.

ALCO products are available through a variety of distributors in the U.S. and Canada. Please contact ALCO Products for your nearest distributor:
