The DIY quiz

Question 1 of 10

During the winter, you notice that your roof has patches of snow melt, while most of its surface remains covered in snow. These patches mean:

• The air in your attic is too cold. Only a small portion of the rooftop is melting while the rest is straining under the weight of the snow
• The air in your attic is too warm and the roof needs to be better insulated or ventilated or both. Ice dams could form and cause some damage
• The rest of the roof needs to be cleared
