A roofer’s perspective: the Ten Rules of Roof Design from GBA.com.
- Avoid valleys
- Just say no to dormers and skylights
- An unconditioned vented attic is better than an insulated roof
- The best roof shape is a simple gable or hipped roof
- Don’t reduce the slope of your roof halfway between the ridge and the eave
- Asphalt felt makes more sense than synthetic roofing underlayment
- Plumbing vent pipes should penetrate the roof near the ridge
- Choose metal roofing or asphalt shingles
- Get flashing details right
- Anticipate ice dams
The most amusing part of the post at GBA.com is the author’s “preemptive comment directed at indignant designers.”
