Breathable Roof Deck Barrier – Milwaukee RooferDeckArmor is an important roofing component used as an underlay below roofing shingles to protect the roof deck from water infiltration. Most modern homes are built weather-tight with minimal ventilation in the attic. So moisture from cleaning, bathing and cooking can easily become trapped in the roof deck.
That is why an effective under-layment should not only be a moisture barrier, but it should also be breathable so that excess moisture can escape to prevent roof rot, decay, or the growth of mold and mildew. Deck-Armor Premium by GAF provides better roof deck protection than traditional asphalt-based felt.
Features that make Deck-Armor stand out among other brands of synthetic under-layment:
Strong and Light WeightRoof under-layment should be strong enough to resist tears and prevent the formation of holes during and after installation. Deck-Armor provides tear resistance that is at least 6 times greater than the 30 lbs. asphalt-felt variety, and it is also three times lighter than #30 felt paper. In fact, a roll weighs just 37 lbs. (17 kg). It is also important to note that the synthetic under-layments installed on roofs before the 2004 hurricanes in Florida provided roof deck protection long after the storms ceased. Thus, even when Mother Nature deals out the worst weather conditions, a synthetic under-layment like DeckArmor will provide superior tear resistance.
DurabilityDurability is one of the most desirable qualities in roof construction. Synthetic under-layments made of polypropylene polymers meets the need for exceptionally durable roofing components because they do not rot, decay or break down like asphalt saturated felts. Using the DeckArmor brand provides an additional advantage because it qualifies you for the Lifetime limited warranty offered by GAF, especially when you use other roof accessories manufactured by GAF such as their Lifetime roof shingles. In addition, this unique breathable under-layment does not wrinkle or buckle like asphalt felt but remains flat and stable, thus creating a more visually appealing roof that will last for many years.
Deck-Armor breathable roof deck protection by GAF is currently the only synthetic under-layment that permits vapor to escape from your roof constantly and keep your roof deck dry and free of fungus. It also meets the physical requirements for roof coverings provided by regulations. Although it is a bit more costly than asphalt felt, the durability, longevity, stability and fast installation make it a wise choice for most roofing projects.
