The fire service responded to a report of a water leak in a building on Håkonsgaten in the city center.

Approximately 15 to 20 liters of water flowed down from the upper floor into a shop, according to duty manager Børre Brekkvassmo at the 110 switchboard west.

The fire service has now closed the main water valve. Whether the dripping stops depends on how much water remains on the floor above.

Understanding and Preventing Ice Dams

Winter brings beauty, but also potential headaches for homeowners – namely, ice dams. These ridges of ice form along the edge of roofs and can cause critically important damage to your home.Let’s break down what they are, why they happen, and, most importantly, how to prevent them.

what Exactly *Is* an Ice Dam?

An ice dam isn’t just a chunk of ice.It’s a result of inconsistent temperatures on your roof. Heat escaping from your home warms the roof above, melting snow.This melted snow flows down,then refreezes when it reaches the colder eaves – the overhanging edges of your roof. This cycle repeats, building up a dam of ice.

Why is this a problem? Water backs up behind the ice dam, potentially leaking into your home through shingles, flashing, and even the fascia boards. This can lead to damaged ceilings, walls, insulation, and even mold growth.

Why Do Ice Dams Form?

Several factors contribute to ice dam formation. Here are the main culprits:

• Poor insulation: This is the biggest offender. Inadequate insulation in your attic allows heat to escape and warm the roof.
• Air Leaks: Gaps around chimneys,vents,and recessed lights let warm air rise into the attic.
• Inadequate Ventilation: Proper attic ventilation keeps the roof temperature consistent. Without it, heat builds up.
• Snowfall: Obviously, you need snow for an ice dam to form! Areas with heavy snowfall are more prone to them.
• Shady Roofs: Roofs that don’t receive direct sunlight stay colder, increasing the likelihood of ice buildup.

How to Prevent Ice Dams

Prevention is far easier (and cheaper!) than dealing with the damage caused by ice dams. Here’s what you can do:

1. Improve Attic Insulation

This is the most effective step. Aim for at least 12-15 inches of insulation, and ensure it covers the entire attic floor evenly.Consider using blown-in insulation to fill gaps and cracks. Energy Star provides excellent resources on insulation levels.

2. Seal Air Leaks

Caulk and weatherstrip around windows, doors, and any penetrations into the attic space. Pay special attention to areas around chimneys and vents. Don’t forget to seal around recessed lights – use IC-rated fixtures designed to be in contact with insulation.

3. Ensure Proper Attic Ventilation

A balanced ventilation system is crucial. This typically involves a combination of soffit vents (intake) and ridge vents or gable vents (exhaust). The goal is to allow cold, dry air to circulate and keep the roof temperature consistent. CertainTeed offers a helpful guide to attic ventilation.

4. Remove Snow from Your Roof (Carefully!)

If you experience heavy snowfall, consider removing snow from your roof with a roof rake. Be extremely careful – avoid damaging shingles and prioritize your safety. Never attempt to remove snow from a roof if it’s icy or you’re uncomfortable with heights.

5. Install Heat Cables (As a Last Resort)

Heat cables create channels for water to flow off the roof. Though, they’re an energy-intensive solution and don’t address the underlying problem. Use them only as a temporary fix or in areas where preventing ice dams is especially challenging.

What to Do If You Already Have an Ice Dam

If you spot an ice dam, don’t try to chip it away yourself – you’ll likely damage your roof. Instead:

• Remove Snow: Carefully remove snow from the roof above the dam to reduce the water source.
• ventilate: Increase ventilation in the attic if possible.
• Call a Professional: A qualified roofing contractor can safely remove the ice dam and assess any damage.

Addressing ice dams proactively will save you money and headaches in the long run. By focusing on insulation, air sealing, and ventilation, you can protect your home from the damaging effects of winter weather.
