You must be diagnosed with parathyroid disease (hyperparathyroidism) if your parathyroid hormone level is high and your calcium level is also high. The excess parathyroid hormone is the CAUSE of the high calcium. The high calcium is caused by a parathyroid tumor--nothing else will cause this.
The ridge of a sloped roof system is the horizontal top area where two sloped roof areas meet. The National Roofing Contractors Association defines ridge as Highest point on a roof, represented by a horizontal line where two roof areas intersect, running the length of the area.. The ridge area on sloped roof systems should be capped to ensure a watertight roof system as well as aesthetic appeal.
In basic gable roof framing, rafters slope upward from the tops of the building's exterior walls and meet at the roof's peak, or ridge. The ridge board is a horizontal timber that serves as a nailing surface for the upper ends of the rafters but in most gable roofs does not bear any of the roof's weight.
