For those who live in cold-weather regions must pay special attention to the formation of ice dams on the roof of their homes. The reason being, if these ice dams are not removed, then they can inflict huge damage to the roof. Ice dams occur when roof gutters are clogged with ice and debris. As water from rain or melted snow goes through the roof and into the gutter, it becomes trapped between the ice present in the gutter and roof shingles. With no passage available for the water, it moves back and underneath roof shingles. Once the water travels underneath the shingles, it stays there for a long period, undergoing a series of freeze/thaw cycles. The water starts to create roof deck damage and rot the wood.
Fixing water damage – an expensive venture
It is very easy and affordable to prevent ice dams if you follow these measures:
- Install a good quality ice and water barrier when installing a new roof. Consult Southern Premier roofing contractors in Fayetteville NC to know how to prevent the accumulation of water inside the shingles, which could damage the roof.
- You need to install the gutters and downspouts, which are large enough to handle the water runoff from your roof. The best Southern Premier roofing Contractor in Raleigh NC will be able to calculate the necessary gutter capacity depending on the roof size.
- You must optimize roof ventilation by balancing intake vents and exhaust vents. There must be an equal balance of cold air intake vents and warm air exhaust vents in the attic space, which is right below the roof deck.
Use the following steps to prevent ice dams on existing roofs:
- Maintain and clean your gutters and downspouts regularly.
- Install heated roof cables in areas where ice damming is a common sight.
