Winters in New Jersey and Pennsylvania often bring harsh conditions that can affect roofs. Heavy snow, ice, and fluctuating temperatures can all weaken and damage roofing materials. Our roofers at Warren Thompson & Son Roofing & Siding in Alpha, NJ want you to know about winter roof dangers so you can prepare. Advanced preparation can help you mitigate seasonal challenges that can decrease your roof’s lifespan and lead to costly roof repairs.
Heavy Snow Accumulation
Snow accumulations in NJ and PA vary greatly but average between 40 and 60 inches per winter. On average, roofs can handle up to 20 pounds of snow per square foot. One inch of snow equals about one to four pounds per square foot of roof space. Wet snow is heavier than dry and fluffy flakes and can pile up quickly.
Heavy snowfall puts your roof under tremendous strain. The added weight increases the risks of sagging, cracking, and potential collapses. Signs you should look for include the following.
- Interior cracks on walls and ceilings
- Popping or creaking sounds
- Doors or windows sticking
- Visible roof sagging
Snow rakes can remove snow from your roof without you climbing a ladder. Heavy snow may require professional snow removal services. You should avoid climbing on the roof because of icy conditions that could lead to accidents.
Ice Dam Formation
Ice dam formation is another serious risk for New Jersey and Pennsylvania roofs because it can cause severe damage. Ice dams form when warm air from your attic melts snow and ice at the peak of your roof. The water runs down to the roof edges, meeting colder temperatures and refreezing. Over time, a thick ridge of ice forms, blocking drainage and causing water buildup under your shingles.
Ice dams can cause water leaks, damaged roof components, and mold growth inside your attic. These ridges of ice can also cause water to leak onto your roof decking, causing the wood to warp or rot. Proper insulation and ventilation are critical for ice dam prevention. We can also install heat cables along your roof edges to help prevent ice dam formation.
Freezing and Thawing Cycles
New Jersey and Pennsylvania winter temperatures frequently fluctuate, leading to a cycle of freezing and thawing. This cycle involves ice melting and dripping into the small cracks in the roof. When temperatures drop again, the water refreezes, leading to expansion. This thermal expansion process can increase wear and tear on roofing materials, including shingles, flashing, and seals.
You may notice the following signs if damage occurs because of freezing and thawing:
- Cracked or missing shingles
- Damaged flashing around skylights and vent pipes
- Water stains on ceilings and walls
Roof inspections are essential after severe winter weather. These inspections allow us to catch damage early before it becomes significant. Sealing cracks and replacing damaged or missing shingles will protect your roof deck and home.
High Winds and Blizzard Conditions
Nor’easters can become powerful in both states, with driving winds dumping feet of snow. The strong, gusty winds accompanying these winter storms can damage roofs by lifting shingles. Shingles may blow away, become cracked, or curl.
Wind-driven snow and sleet can impact vulnerable roof areas like flashings, vents, and chimneys. Moisture entering your home through these areas can lead to mold, mildew growth, and structural damage.
In severe winter storms, the wind can expose your underlayment, causing interior leaks. Your home may also have loose or detached gutters and downspouts.
You should schedule a roof inspection before winter weather to check for any damage or loose components. After a severe storm, schedule another inspection to check for potential storm damage. Your insurance company may cover roof damage caused by winter weather under your homeowner’s insurance policy. Report any damage to your insurance carrier right away.
Gutter Blockages and Ice Buildup
Your gutters are a critical component of your roof. They help usher water from your roof and away from your home’s foundation. Clogged gutters can trap water that can freeze during cold temperatures. The weight of the ice accumulation may cause your gutters to become torn away from the roofline.
In the fall, you should clean your gutters to remove leaves, limbs, and debris. You should also consider installing gutter guards to prevent debris buildup. We offer gutter repair services; you should seek them at the first sign of damage. Prompt repairs can help protect your gutters so you can avoid replacing them prematurely.
Learning From Historic Winter Storms
New Jersey and Pennsylvania have a lengthy history of impactful snow storms. The 1996 blizzard left parts of Pennsylvania with over 30 inches of snow, leading to widespread roof damage and collapses.
In 2010, a Nor’easter dumped over two feet of snow in many parts of New Jersey and Pennsylvania, causing ice dam development on many roofs. Many homeowners contacted insurance companies and filed claims after this tremendous storm.
No one can forget Winter Storm Jonas in 2016. The storm blanketed both states with heavy, wet snow that caused extensive roof damage. Roofs that had not been appropriately inspected before the storm could not handle the immense weight of snow. These storms highlight the need for preparedness.
Why Professional Roof Inspections Matter
Winter weather can amplify minor roof issues that may go unnoticed during the warmer parts of the year. You may miss minor issues like missing shingles or damaged flashing. Winter weather can expose these areas if left alone, leading to severe structural damage.
Scheduling a professional roof inspection offers the following benefits.
Safe Ice and Snow Removal
A good rule of thumb is that if there is more than a foot of snow on the roof, it needs professional removal services. Professionals can remove snow and ice buildup without damaging roofing materials.
Roof Repairs
A professional roof inspection allows us to find damage before it progresses. Areas where shingles crack, curl or blow away expose your roof deck and home to moisture. Replacing damaged or missing shingles ensures a watertight roof, preventing moisture from seeping into your home and causing ongoing damage that becomes more expensive to repair.
Reinforce Flashing and Gutters
A roof inspection also ensures the soundness of your flashing and gutters. These areas often bear the brunt of brutal winter weather. By reinforcing critical components, we can help protect your roof and home from damage during snow and ice events in the winter.
Improved Energy Efficiency
We will check for proper ventilation and attic insulation during a roof inspection. Both are critical for protecting against ice dams in the winter. Addressing these issues before winter will help you maintain a more efficient home and avoid rising electricity costs.
Extend Your Roof’s Lifespan
Routine inspections and maintenance can help prolong your roof’s lifespan. Neglected roofs do not last as long and often need more repairs. We recommend scheduling an annual roof inspection.
Peace of Mind
Knowing your roof is in sound condition offers peace of mind through winter’s challenging weather. You will have to worry less about roof issues like ice dams and leaks, allowing you to focus on other essential tasks.
