Even though most building codes require that residential roofs support the biggest snowfalls in your area, there is still a risk of roof damage. The main reasons to clear the snow from roofs is to prevent ice dams (which can lead to property damage caused by leaks) and cave-ins. Here is what you can do if you decide to remove the snow on your roof:
- In general, to prevent big piles, snow on roofs should be removed when it’s about 6 inches deep.
- Make sure you leave at least 2 inches of snow on the roof to avoid serious damage to the roof covering and additional damage.
- If you live in a one-story home, stay on the ground and use a rake with a telescopic handle. For taller homes, use the rake to clear the overhangs.
- Be careful not to hit any overhead power lines when raking the roof.
- If using a rake is inefficient, the snow needs to be shoveled by someone on the roof. However, don’t try to tackle this dangerous job by yourself. Hiring a licensed contractor is the safest way to go.
- If you’re determined to shovel the snow yourself, make sure your ladder is stable and use a safety harness on the roof. For sloped roofs, start shoveling at the ridge and move toward the eaves.
- Never use mechanical equipment specialized in snow removal. Using these tools increases the risk of damaging your roof.
- Don’t put salt or salt products on the roof. Although salt is a natural enemy to ice and snow, it can also discolor shingles and kill the vegetation the melted snow falls upon.
- Dispose of the snow in designated areas on the ground, away from walkways. Don’t dump the snow near building exits, ventilation exists or drain downspouts.
