Which statement about low slope roofs is correct?

1. They are typically more suited to northern cottages.

2. They can contribute to additional snowload during winter months.

3. They have an angle greater than high slope roofs.

4. They are less likely to experience ice damming issues.

5. They are often implemented to reduce cooling needs.

6. They always require more frequent maintenance.

The correct answer is: They can contribute to additional snowload during winter months.

Low slope roofs are designed to have a pitch of less than 3:12, which means they do not have a steep incline. One key aspect of low slope roofs is their behavior in winter conditions. Because of their slope, these roofs can accumulate snow more easily compared to steeper roofs. The weight of the snow can lead to significant snow load issues, as the flat or low slope fails to facilitate quick drainage, thus causing the snow to remain on the surface longer. This additional snow load can lead to structural stress and potential roof collapse if the accumulation is excessive. When considering the other statements, they do not accurately describe the characteristics or implications of low slope roofs. For instance, low slope roofs generally do not have an angle greater than high slope roofs, and suggesting that ice damming issues are less likely ignores the fact that the lack of pitch can actually exacerbate ice damming due to more prolonged snow and ice presence. Similarly, while low slope roofs can help with cooling needs and can be easier to maintain in some respects, they do not inherently require more frequent maintenance. Therefore, the statement regarding their contribution to snow load accurately reflects a critical aspect of low slope roofs and their performance in cold weather.
