What Is the Concern with Snow on Asphalt Shingle Roofs?
Under normal winter conditions, snow and ice generally do not need to be removed from GAF Asphalt Fiberglass Shingles. However, removal may be necessary if:
- The weight of the snow and ice puts the building under severe load.
- The melt/runoff creates severe leakage.
- Ice at the eaves poses a danger to foot or vehicular traffic below.
Evaluating the Situation
Before taking action, carefully evaluate the situation by considering the following questions:
- Is the water coming in creating extensive damage?
- Is the weight significant enough to harm the structure or significantly damage the interior?
- Will falling ice or snow hurt someone or damage something?
- Do you possess the necessary skills to remove the ice and snow without hurting yourself or damaging the roof and making the situation worse?
What Should You Do If Any of the Above Apply?
To prevent personal injury or damage, do as little as possible. Here are some key points to consider:
- Minimal Intervention: The greatest chance of injury or extensive damage comes from trying to clear too much. Often, clearing the overhangs, sidewall areas, valleys, or other drainage ways will eliminate the situation.
- Call a Professional: It is best to call a roofing professional trained in the proper removal of snow and ice.
What Should You Not Do?
GAF does not recommend the following:
- Avoid Steep Slopes: Do not climb on a steep slope, especially if you are unsure of your abilities and lack proper fall/safety equipment.
- No Heavy Tools: Avoid using hammers, chainsaws, axes, picks, or other similar tools which can damage the roof.
- No Chemical Deicers: Do not use chemical deicers as they can damage the roofing materials, siding, vegetation, or yourself if not handled properly.
Preventing Leakage or Heavy Burden on the Roof
To prevent potential issues, consider the following options:
- Install Electric Heat Tape: Use electric heat tape or engineered electric roof ice melt systems in problem areas, such as eaves, sidewalls, or dormers. Follow the manufacturer’s instructions and recommendations.
- Install Snow Guards: Snow and ice guards can prevent the slippage of large blocks of snow or ice off the roof.
- Clear Debris: Clear valleys or drainage ways of debris, such as leaves, prior to snowfall or ice storms.
- Use Leak Barriers: Install GAF WeatherWatch® or StormGuard® in critical areas to prevent leakage.
- Ensure Proper Design: Ensure the structure is properly designed for the snow and ice load in your area.
Is My Warranty Affected If I Remove Ice and Snow?
No, the GAF Limited Warranty for the shingles will remain in effect. However, any damage such as cracking, punctures, foot damage, or tearing is the responsibility of the owner and is excluded from GAF’s responsibility under the terms of the Limited Warranty.
Conclusion
Proper snow removal and prevention measures can help maintain the integrity of your asphalt shingle roof during winter. By following these guidelines, you can protect your home and ensure the longevity of your roofing system.
