4 Key Components of a Long-Lasting Roofing System

The more you understand about your roof, the more you can take care of it and maximize its service life. Although shingles are all you see from the ground, your roof has many components that work together to protect your home from the elements. Some parts may be optional, but each one adds value to the overall quality of the whole.


As one of the most experienced local roofers, DryTech Roofing shares the key components your roofing system must have:

1. Underlayment

The underlayment keeps the wood deck safe from wind-driven rain that manages to pass through the shingles. Usually made from felt, this durable paper serves as your roof’s last line of defense against water intrusion. Certain types of underlayment are designed to waterproof the most vulnerable areas, like valleys, and significantly reduce the chance of leakage with their self-adhering ability.

In GAF’s Lifetime Roofing System, its Roof Deck Protection also helps breathe out excessive moisture in the attic. Plus, it allows the shingles to lay flatter to prevent buckling, minimizes blow-offs and creates a uniform appearance.

2. Flashings

These thin pieces of metal exist for one reason: to increase the water resistance of your roof’s weakest underbellies. One of the most popular types of flashing is the drip edge. It’s placed on the shingles’ leading edge near the gutter and over the underlayment. When installed to manufacturer’s specifications, expect to spend less on roof repair over the long term.

3. Shingles

Not all shingles are equal. Apart from differences in aesthetics, some are thicker and heavier to deliver exceptional wind resistance. Specialized products reflect solar heat better for excellent energy efficiency and stand up to hail impact for increased durability.

4. Ridge Vents

Local roofers would tell you that adequate attic ventilation contributes to roof longevity. The right combination of intake and exhaust vents optimizes airflow, allowing insulation to work efficiently and helping regulate indoor temperature.
