Crucial Roles Underlayments Play in Roofing Systems

The underlayment is one of the most important components of an asphalt shingle roofing system. You don’t see it, but it contributes to your roof’s weather resistance, beauty and energy efficiency.

If you ask Quality Assurance Roofing, these are the most crucial roles roofing underlayments play:

Protecting Against Wind-Driven Rain

The underlayment serves as your roof’s last line of defense against wind-driven rain. It covers the underlying sheathing completely, acting as a temporary barrier against every drop of water that manages to pass through the shingles. In case of shingle damage, it helps the wood deck stay dry and structurally sound, inhibiting rot and preventing leakage.

Exhaling Excessive Moisture

Breathable roofing underlayment materials help remove damaging moisture from your attic. An excellent case in point is the GAF’ Tiger Paw™ Roof Deck Protection, which expels nearly twice as much moisture as leading non-breathable underlayments. Without trapped heat and moisture, your roof will last longer, and its shingles are less likely to curl over time.

Allowing Shingles to Lay Flatter

Apart from serving as a waterproofing and moisture-controlling layer, the underlayment helps keep shingle blow-off to a minimum, too. When installed properly, it allows roofing materials to lay flatter, preventing them from buckling. When strong winds blow, they’re more likely to remain in place. Plus, properly laid shingles create a more uniform look, which contributes to curb appeal.
