Greenwich Roofing: Article About Roof Inspection After Snow
Many of the weather events that lead to Greenwich roofing issues tend to occur during the winter months. Accumulated snow and ice can have a detrimental effect on the roofing system, especially if the homeowner does not adopt a proactive approach. Following any adverse winter conditions, homeowners should make it a habit to inspect the roof for damage and to address any problems as quickly as possible. Understanding what to look for following these conditions is essential.
Building code requirements are designed to ensure that the roof structure is able to support the weight of accumulated snow during even the harshest of winters. Even so, homeowners should remain attentive to the type of snow and the extent to which it has accumulated in order to properly assess whether removal is necessary. If the snow is wet or there is a greater volume of snowfall than is typically expected, the homeowner should consider hiring a professional to remove it. If total removal is not needed, it is still good practice to remove any snow from the roof's edge if it is possible to do so without having to access the roof, as this may help prevent the formation of an ice dam.
The homeowner should also inspect how the snow interacts with the roof. During a light dusting of snow, for example, a homeowner may observe that the snow is melting unevenly. This could be due to hot spots on the roof that are caused by improper attic ventilation, which can lead to ice dams developing during heavier snowfalls.

If the homeowner notices this problem early in the winter months, it may be possible to address the ventilation issue or to install additional insulation that prevents heated air inside the home from escaping into the attic.
Although the homeowner should do everything possible to prevent an ice dam in the first place, it is still important to be able to recognize when one has developed. Icicles that form along the eave are a common indication, but the homeowner should also inspect the roof valleys, exhaust vents, skylights, and any areas of the roof that have a low pitch.
Once an ice dam has formed, homeowners may be tempted to use a hammer to chip away at the ice, but this is a mistake that can damage the roofing components. The ice should be melted using calcium chloride, and the source of the problem should be addressed in a timely fashion to prevent future issues.
While exterior inspection is certainly important, interior inspections should not be overlooked. Regularly checking the attic may reveal water damage or leaks that are not visible from the outside, enabling the homeowner to address the source of the problem before it causes the kind of major damage that requires significant repair.
