James Hardie vs. Mastic Vinyl — What’s Best for Homes in Western Kentucky?

Choosing new siding is a major decision — it affects your home’s look, durability, energy performance, and resale value. In our region (Western KY / NW TN), siding must handle heat, humidity, storms, and seasonal temperature swings.


You have excellent options. Two of the most trusted siding systems available are:

  • James Hardie® fiber cement siding

  • Mastic® vinyl siding by Ply Gem


Both are quality products — and we install both at True Line Roofing — but they serve slightly different homeowner priorities.


Below is a close look at how they compare.


James Hardie Fiber Cement Siding


James Hardie is widely regarded as one of the most premium siding products on the market. Their engineered fiber cement formulas are built to handle extreme weather and stand the test of time.


Key Strengths


1️⃣ Engineered for ClimateJames Hardie products are designed with ClimateZone® Technology™ — meaning they are formulated specifically to withstand conditions like ours: heat, humidity, moisture, and temperature cycling.Source: James Hardie product catalog

  • warping

  • swelling
