Find Ratings

What's behind our siding Ratings?

Experts at our National Testing and Research Center tested 30 models in siding to see which ones perform best.
We look for:
  • Overall score
    Overall score for siding is based primarily on resistance to fading, impacts, and wind in our tests. Displayed scores are rounded; products are listed in order of precise overall score.
  • Thick
    Thickness is as measured by our testers.
  • Fading
    Fading reflects resistance to color changes after accelerated weathering tests using intense heat, UV light, and water spray to mimic typical weathering cycles siding would encounter on an actual home.
  • Cold impacts
    Cold impacts is resistance to damage from blows at 0 degree Fahrenheit.
  • Warm impacts
    Warm impacts is resistance to damage at roughly 70 degree Fahrenheit. Impacts mimic blows from fallen objects and other mishaps.
  • Wind
    Wind is siding's ability to stay attached in lab tests simulating high winds; the best withstood forces equivalent to more than 150 mph.
  • Rigidity
    Rigidity denotes stiffness; stiffer siding should appear flatter and more woodlike on a wall.

Siding buying guide

New siding is one of the most visible ways to give your home a makeover now and make it easier to sell later. And siding isn't just decorative: Loose or cracked panels or shingles can allow entry to moisture and insects, leading to expensive structural damage. What's more, performance can vary significantly between and even within types. Use this guide to find a replacement.

Past tests found significant differences by type and brand--and even within the same brand. Some siding was far less resistant to cracking from impacts in warm and cold weather, an especially important consideration for active families with children. And some was less likely to stay put in a wind storm, based on our simulated 150-mph winds. We also found that some vinyl siding--still the best-selling kind--was more prone to fading under ultraviolet light, especially important in sunny climates and where trees don't provide much shade.

Vinyl, plastic, and other synthetic materials are also getting much more realistic: Thanks to better graining and deeper profiles that cast wider shadows, some vinyl siding looks much more like wood for a small fraction of what you'd pay for the real thing. Check under Types to determine which material--vinyl, plastic, fiber cement, or wood--best suits your taste and budget.
