Dealing with a snow-laden roof can be tricky. Of course, winter presents its own set of challenges, particularly for northern climate homeowners. Severe snow loads can cause stress to the roof, which, in some cases, will require roof repair.
Can you blow snow off a roof to repair or prevent more damage? This protocol will guide you on when it may be necessary to remove roof snow, evaluate the risks involved, and learn the safest approaches to remove it, preventing damage where possible. With the guidance presented in this article, learn how to handle snow on your roof safely and efficiently. If you need reliable and professional roofing services, our team of expert Berks County roofing contractors is ready to assist you with all your roofing needs.
Understanding the Impact of Snow on Your Roof
A typical roof is built to bear a certain load of snow, usually more than the area’s code of construction. Unfortunately, excessive, wet snowfall can overload the structure of your roof. This is particularly the case for flat roofs, which do not shed snow as easily as sloped roofs.
Weight: The Primary Concern
Wet snow is significantly heavier than dry, fluffy snow. Dry snow might weigh around 5 pounds per cubic foot, while wet snow can weigh up to 20 pounds. Accumulated wet snow of a couple of feet is sure to be more than the typical building code design minimum.
Roofs in areas with heavy snowfall often need to withstand significant snow loads. Just think of the destruction or sudden flood a place can cause. Monitor snow accumulation to prevent ice and damage.
Ice Dams and Roof Repair
Ice dams form when melting water refreezes, preventing proper drainage. When they accumulate, the resulting water can lead to roof leaks and consequent damage. Preventing ice dams usually involves enhancing attic ventilation and insulation.
Professional roofing contractors in Chester County, PA are best to perform these fixes. They usually cannot be dealt with during active snow and freezing stages. Therefore, it is in the best interest of households to handle snow removal properly to prevent these kinds of issues.
Assessing the Situation
Light, dry snow a few inches deep rarely causes enough stress to a roof. However, a foot or more of heavy, wet snow might warrant removal, especially in areas that accumulate snow.
Not even less snow becomes a problem when other factors contribute weight to the roof. Pay special attention to snow buildup to prevent roof collapse, and shoveling snow properly is an important way to avoid health issues for yourself and your family.
Safe Snow Removal Methods for Roof Repair or Prevention
If you remove snow, roof rakes are a better option than climbing on the roof. Applying a roof rake from the ground removes snow from the lower edge. Leave several inches of snow to prevent the roof surface from being damaged. This also protects from damage to roofing shingles or other roofing materials.
A shovel should be used if safe access is available to a less sloped or flat roof. This allows for more controlled snow clearing. Use care when working near any existing roof penetration(s), such as a plumbing, vent, or solar panel installation. Exercise caution when snow brushing, be gentle with raking roofs, and do not forget the risks of winter conditions while working.
Use a de-icer for packed snow or ice. Calcium chloride pellets do not scratch as much as salt and can help break up the snow, so it is easier to sweep. Consider how weather conditions and melting water may influence your next steps to remove heavy snow while minimizing future problems.
When to Hire a Professional
Roof snow removal can be dangerous, with falls being a major hazard. A professional looking at steep and high-to-difficult-to-access roof work is normally the safest option. A reliable roofing contractor and roof snow removal are available in good health to minimize the risks of roof damage. Snow removal stops further damage, but it provides a restoration, not a restoration tool. Repairing leaks, damaged shingles, or structural issues requires experience and the right weather conditions.
Clearing snow reduces stress on a damaged roof. However, it doesn’t address the underlying issues. It should be noted that water damage may be undetectable under snow, and a compromised roof is particularly vulnerable to damage under severe winter conditions. Where a damaged roof has allowed wet snow to come in contact with underlayments or support structures, these components will deteriorate and be more challenging to remove until roof winter conditions return to normal. The risk of snowslides is further amplified by lower water content absorption and snow load-bearing capacity. Remember to also avoid ice when possible during roof snow removal.
Protecting Your Roof in Winter
Routine roof care avoids extensive repairs caused by weather damage and natural aging. This includes routine inspection (even when the ground is covered with snow) and quick repair.
Timely snow removal, especially for flat roofs, is crucial. This, plus routine upkeep, contributes to the increase of the roof’s life, whatever the material.
Give particular consideration to the following factors when checking whether it is time to clean your roof, whether it is pitching or low-slope/flat sheet membrane. This reduces the risk of subjecting your roof to premature damage and further reduces the chance of replacement in the future.
You protect your roof by realizing the impacts of snow accumulation, evaluating your circumstances, and using safe approaches to removal. Safety should always be your priority. When in doubt, consult a professional roofing contractor. For more information, contact us today.
