Winter Roof Damage: 3 Red Flags Every Homeowner Should Watch For
Of all the seasons, winter presents the greatest threat to Twin Cities roofs. If you’re unaware of what constitutes a threat to your roof, it’s all too easy to let minor damage go undetected. And minor roof damage almost always progresses if left unrepaired.
To help you recognize when your roof might be at risk, the experts at Eastern Roofing & Siding share three common red flags that may indicate the need for a roof inspection.
Excessive Snow Accumulation
The structure of your roof determines how much weight it can handle. But when it comes to snow accumulation, it’s difficult to tell just how much snow buildup weighs. Wet snow is considerably heavier than its powdery counterpart, and it can place considerable stress on the structural components of your roof when it isn’t promptly removed.
If you’ve allowed snow to pile up on your roof, it may be at risk for damage. This is especially true if your roof is nearing the end of its lifespan or if the structure has suffered previous damage. To avoid serious roof problems, have a roofing contractor perform an inspection if you suspect any degree of leakage, sagging, or other forms of damage.
Condensation in the Attic
When warm air from inside your house rises into your attic and meets the cold underside of your roof, condensation can form. When there’s a considerable amount of snow on top of your roof or when an ice dam forms along the edge of it, your attic may be especially prone to condensation development.
When it’s freezing outside, that condensation becomes frost, but as soon as temperatures begin to rise, it liquifies and can present a major danger to your roof. When moisture sits on the underside of the structure, it can spur mold growth and rot, which can contribute to further roof issues down the road.
Plus, excessive moisture inside your attic can render your insulation practically useless. Since water interferes with insulation’s ability to slow heat transfer, expect your heating bills to rise.
To find out if there’s condensation in your attic, you’ll need to climb up there and perform a quick inspection. If you notice rot, mold, or moisture, one of the following issues may be the culprit:
● Inadequate attic ventilation
● Improperly vented exhausts that are routed through the attic
● Minor roof leaks
● Hairline pipe fractures
● Unvented combustion appliances
● Wet basement or crawlspace
To determine whether a roof leak or inadequate insulation is contributing to the condensation in your attic, you’ll need to have a roofing contractor inspect the area.
Ice dams form when warm air from inside your home rises into your attic and melts the snow on the upper portions of your roof. When the melted snow drips down toward the edges of the roof — where the temperature is colder than the apex — it refreezes, forming a layer of ice.
When this process continues occurring, the layer of ice along the edge of your roof can become quite thick. Eventually, it will prevent additional runoff from exiting the roof, and that water will begin pooling behind the ridge of ice. As the water sits, it can seep beneath your shingles and damage the structural components of your roof.
If you’ve noticed an ice dam forming along the edge of your roof, prompt removal is critical to prevent water-related roof damage. If you’ve allowed an ice dam to sit, you should schedule an inspection with a licensed roofing contractor to make sure your roof is damage free.
We’d be remiss not to mention that ice dams are almost always preventable. Check out our helpful ice dam prevention tips for more information.
