What it concludes

• Cutting common rafters before installing the ridge beam makes it easier to raise or lower the ridge beam slightly for a snug fit.
• A 16-penny nail is the right size to use in framing a roof in almost every situation.
• Toenails should go in at about a 45-degree angle with half the length of the nail through the rafter and half into the beam or wall.
• OSB drag struts tie the roof diaphragm back into the house framing in a bulletproof way.
• Building safety platforms and scaffolding is safer and worth the time and effort over using ladders.
