Introduction
When it comes to safeguarding your home from the elements, the roof plays a pivotal role. But what lies beneath those shingles? What are the unsung heroes that keep your home dry and secure? Today, we at Equity Roofing will delve into the critical components of a roof—specifically, underlayment and drip edging. As one of the leading Central PA roofers, we believe in educating our clients about the intricacies of roofing systems.
What is Underlayment?
Underlayment is the unsung hero of any roofing system. It's a moisture-resistant or moisture-proof layer that sits directly under your shingles. This barrier is essential for protecting your roof decking from condensation and severe weather conditions that shingles alone cannot fend off. Building codes mandate the use of underlayment, and many shingle manufacturers will void their warranties if it's not installed.

The Evolution of Underlayment
Initially, underlayment was a temporary measure to protect the interior of homes or businesses during the installation of new shingles. Over time, shingle manufacturers began to produce their own underlayment, recognizing its importance for the overall integrity of the roofing system.
Types of Underlayment
Tar Paper
Once the standard, tar paper is an asphalt-saturated felt paper. It's a heavy, sticky product made from polyester or fiberglass fleece soaked in a water-resistant agent. However, modern roofing materials have largely replaced tar paper.
Synthetic Underlayment
This type of underlayment is made from either polyethylene or polypropylene, making it lighter and more durable than tar paper. It offers better traction for roof installers and is more tear and water-resistant. Although slightly more expensive, the benefits of synthetic underlayment far outweigh the costs.
Ice and Water Shield
This is a specialized waterproofing underlayment used to protect vulnerable areas of your roof. It adheres to the roof deck, providing a robust seal against the elements. It's typically used in conjunction with tar paper or synthetic underlayment.
What is Drip Edging?
Drip edging is a metal strip that directs water from the roof into the gutter or down the fascia. It's particularly crucial for roofs with plywood decking, as plywood is more susceptible to water damage than solid wood. Without the correct drip edge, water can rot the edges of your decking and run behind your gutters.
