How do I stop shingles from blowing up?
You can change the direction of the exposed raised edge of the ridge cap shingles by installing them – in your case – from south to north, the opposite of your current state.

What happens when shingles come off roof?

Why does it look like my roof is sagging?
Sagging roofs are typically caused by insufficient internal bracing or undersized rafters/trusses combined with excessive loads of weight. Snow, ice, wind, and even too many layers of shingles can add stress to your roof and cause sagging.
Where do trusses fail first?
When a truss collapses, it is usually because of the failure of either the top chord (in compression, unless a cantilever) or the bottom chord (in tension, unless a cantilever). If a truss buckles or overturns, it is usually because of the failure of an adjacent truss or its bracing.
