On Top of Roofing: Understanding What’s Over Your Head

PDH | 1

A typical roof can be riddled with tricky transitions, especially when marrying steep and low slope roofs. Transitions not only need to consider the integration of different materials, but also the continuity of the control layers—water, air, thermal, and vapor. There are a few tricky transition areas that can be overlooked or improperly detailed in the design process, and are sometimes left for the contractor to “figure out.” Some of these overlooked and underappreciated details include steep-slope to low-slope integration, rising walls, clerestories, parapets, drainage, and ventilation. We’ll consider the risks associated with getting it wrong and review ways to get it right.

Learning Objectives

  • Newton’s law of gravity: Water flows downhill but what about air?
  • Understanding attics via the 2nd Law of Thermodynamics – heat build-up, ventilation, & condensation.
  • Dealing with water in the air… and knowing when to worry about it.
  • Discuss requirements to manage moisture, air, vapor, and thermal continuity
  • Leveraging the chimney effect for effective attic ventilation.
