How snow & ice impact the roof

How ice dams are formed

Snow & ice may impact your roof: Heres how

Snow & ice can have significant impact on your roof, especially in regions that experience cold winters. Here are some of the ways in which snow & ice may affect your roof. 

1. WEIGHT: Accumulated snow & ice can add significant weight to your roof. This extra load can stress the structural integrity of your roof, potentially leading to sagging, leaks or even a collapse in extreme cases. It is essential to know your roof's weight bearing capacity & clear off excessive snow when necessary. 

2. ICE DAMS: Ice dams occur when snow on the roof melts & them refreezes at the eaves or in the gutter. This ice buildup can block proper drainage, causing water to back up under the shingles & into your home. This can result in roof leaks, damaged shingles, & even interior water damage. 

3. FREEZE: THAW CYCLE: The repeated freezing & thawing of snow & ice on your roof can cause the roofing materials to expand & contract. Over time, this can lead to the deterioration of roofing materials, especially if they are older or in poor condition. 

4. GUTTER DAMAGE: Ice can also damage your gutters. When ice accumulates in gutters & downspouts, it can create blockages, causing water to overflow & potentially damage the fascia & soffit. The weight of ice in gutters can also cause them to pul away from the roof line. 

5. ROOF LEAKS: As snow & ice melt, water can find its way through any vulnerable areas of the roof, such as damaged or missing shingles, seams, or even flashings. This can results in roof leaks & water damage to the interior of your home. 

6. CONDENSATION: Cold weather can cause condensation to form in your attic or under the roof. If not properly ventilated, this condensation can lead to moisture problems, including mold growth & rot. 

To keep the impact of snow & ice on your roof at bay, consider taking the following suggestions: 

1. INSULATION & VENTILATION: Properly insulate & ventilate your attic to reduce the risk of ice dam formation & condensation. 

2. SNOW REMOVAL: Safely remove excess snow from your roof using a roof rake or by hiring a professional if necessary. Don't attempt to remove ice buildup, as this can damage your roof. 

3. GUTTER MAINTENANCE: Keep your gutters & downspouts clear of any debris to ensure proper drainage. Install gutter guards to prevent ice & debris from accumulating. 

4. ROOF INSPECTION: Regularly inspect your roof for signs of damage or wear & tear. Repair any damaged shingles flashing or seals immediately. 

5. PROFESSIONAL ASSESSMENT: If there is a concern about the condition of your roof or the weight or snow & ice, consider having a professional roofing contractor assess your roof & make recommendations. 

Remember that safety is the number 1 concern when dealing with snow & ice on your roof. If you are unable or unsure about how to address these issues, please dont hesitate to call your trust professional.
