When it comes to roof replacements in the Inland Northwest, homeowners need materials that can handle heavy rain, snow, and moisture fluctuations. One of the most critical—but often overlooked—components of a durable roofing system is underlayment.

At New Heights Roofing, we recommend using Malarkey Permeable Synthetic Underlayment in shingle roof replacements because it outperforms traditional alternatives in durability, breathability, and weather resistance.

What is Malarkey Permeable Synthetic Underlayment?

Malarkey’s permeable synthetic underlayment is an advanced moisture-management layer installed between the roof deck and shingles. Unlike traditional felt or non-breathable synthetic underlayments, Malarkey’s version is engineered to allow trapped moisture to escape while still providing a waterproof barrier against the elements.

How We Use Malarkey Underlayment in a Roof Replacement

When replacing a roof, our expert crew follows these key steps:

1. Removing Old Materials

We start by tearing off old shingles, outdated underlayment, and any damaged flashings. This ensures we’re working with a clean, solid roof deck before installing new materials.

2. Installing Malarkey Permeable Synthetic Underlayment

  • We roll out Malarkey underlayment across the entire roof deck and secure it in place.

3. Adding High-Performance Shingles & Flashings

  • We then install Malarkey Vista® or Legacy® shingles, which pair perfectly with their underlayment for long-term durability.
  • We finish by sealing seams, installing flashings, and ensuring proper attic ventilation to maximize the roof’s lifespan.
