Checking for potential roof damage after a heavy winter

Munz Roofing and Siding provides proactive tips to help you prepare for winter’s fury.

Imagine this: El Niño has overwhelmed your roof with snowfall since Christmas, and it eventually starts to thaw just before the MLB spring training pitchers and catchers convene.

Did the snow and ice cause any harm to your roof?

It is a question that home owners in most of New Jersey and Southern Pennsylvania have not had to deal with for almost half a decade. But it might be different this year.

Yes, we know winter has only just started, and it has not even snowed yet. But now is a good time to have a plan in place for the spring if we DO have a heavy winter of snow for the first time in half a decade

As the winter season sets in, preparing your home’s roof for potential heavy snowfall and ice accumulation becomes essential.

Although it might seem premature to plan for spring maintenance amid the winter’s arrival, having a strategy in place ensures your roof remains resilient after a period of heavy snow and ice.

Cracked or Missing Shingles:

Cold winter weather can cause serious damage to your roof, like shingles cracking or falling off. A careful inspection of your roof for any visible signs of damage is a smart and proactive step. Carry out a thorough assessment, looking for shingles that may be loose, buckled, or missing.

Ice Dams:

Ice dams are formations that occur when snow melts, flows down your roof and refreezes near the edge. This cycle of thawing and freezing creates a barrier that prevents further runoff, causing water to pool up behind the dam. Water can go under the shingles and get inside your home, causing leaks or damage to the structure.

Preventing ice dams forming on the edge of your roof can help stop costly roof repairs after the winter months.

Icicles and Ice Accumulation:

Another concern during winter is the formation of icicles and ice build-up on your roof. Icicles can pose a physical hazard, especially if they fall, but they can also signal larger issues such as poor insulation and ventilation in your attic. Furthermore, the weight of accumulated ice can strain the structural integrity of your roof.

Sagging Roof or Gutters due to Excessive Weight from Snow and Ice:

A significant concern during winter is the excessive weight from accumulated snow and ice. This load can lead to a sagging roof or drooping gutters, affecting the structural integrity of your home. In extreme cases, the weight can become so substantial that it causes the roof or gutters to collapse.

Winter storms can cause excessive damage, and the extent of the damage (such as damaged shingles that require repair or replacement, or the presence of mold and mildew due to leaks) may not become apparent until spring.


Another telltale sign of potential damage during winter is the presence of leaks in your home. These leaks often manifest in your attic or interior ceilings. Look out for signs such as water stains, damp spots, or wet insulation. Sometimes, if the leak is substantial, you might also notice dripping water.

Flashing Damage:

Flashing—the thin pieces of metal installed on your roof to direct water away from critical areas—can be compromised by heavy snow and ice. These strips are typically found around vents, chimneys, and valleys between roof slopes. The weight and pressure from accumulated snow can distort the flashing, leading to gaps where water can penetrate and potentially cause leaks or other damage.

Gutter Blockages:

An often overlooked aspect of winter roof maintenance is ensuring that your gutters are clear of debris. Leaves, branches, and other debris can accumulate in your gutters over time, causing blockages. These blockages can prevent the free flow of melting snow and ice, causing water to back up onto your roof and potentially leading to leaks and structural damage.

To prevent this, carry out regular gutter cleaning, especially before the heavy snowfalls of winter.

Siding Damage:

Check your home’s siding regularly for any signs of winter damage. This includes looking for cracks, breaks, or chips in the material, which can occur due to the extreme cold. These damages can compromise the integrity of your home’s exterior, potentially leading to more extensive repairs if left unchecked. It’s also important to be aware of any indications of water infiltration such as damp patches, peeling paint, or mold growth.

This could signal a breach in your siding, allowing moisture to penetrate into your home and potentially lead to structural damage or mold issues. Early detection and repair of siding damage can help maintain your home’s aesthetic quality and structural integrity, while avoiding more costly repairs down the line.

Structural Integrity:

If you notice any interior changes such as cracks in the walls or ceilings, or doors and windows that no longer close properly, these could be signs of potential roof collapse due to heavy snow weight.
