How New England Weather Affects Your Siding—and What to Do About It

When you call beautiful Merrimack, NH or the surrounding New England communities home, you know the charm—along with the challenges—of our region’s unpredictable weather. Winter storms, spring thaws, summer heatwaves, and autumn rains don’t just test your patience; they put your home’s siding through a rigorous trial, too. If your property’s exterior is starting to show signs of wear or damage, understanding how New England weather affects your siding is key to keeping your investment protected and your curb appeal high.

The Big Three: Siding Enemies in New England Weather

Across Bedford, Nashua, Manchester, Derry, and into the heart of Southern New Hampshire, siding damage is most often caused by:

1. Freeze-Thaw Cycles 

Temperatures in Merrimack and neighboring areas often swing wildly from day to night. Moisture seeps into siding cracks, then freezes and expands, widening gaps and leading to warping or splitting—particularly in wood and vinyl sidings.

2. Intense UV Exposure 

While summers are brief, the sun’s UV rays can be intense enough to fade colors, cause cracking, and make siding brittle, especially if installed prior to the latest advancements in fade-resistant materials.

3. Heavy Precipitation 

Snow, sleet, and rain are regular occurrences well beyond just February in New Hampshire. Poorly sealed siding or old caulking can allow water to get behind panels, promoting rot, mold, and eventual structural concerns.

Can Siding Crack in Cold New England Winters? 

Absolutely! The combination of shrinking materials in deep cold and the expansion of trapped moisture can cause vinyl or wood siding to crack or split, often revealing itself as visible seams or warped panels by late winter.

Winter Woes: Siding Issues to Look For

February is peak season for the effects of winter weather on homes. Here’s what to check for around your property right now:

• Visible cracks or gaps newly appearing in siding boards
• Warping or buckling, particularly near window frames or gutters
• Icicles forming along the siding’s edge—often a sign of trapped moisture
• Mold, mildew, or discoloration at the base of your siding.

Why It Matters: Siding isn’t just about good looks. Compromised siding can lead to higher heating bills, water infiltration, and devalued property—a particular concern given New Hampshire’s highly variable property market.
