Morning. The roof’s gotta have a strong frame—solid joists or trusses spaced properly. Use good quality, rated lumber or engineered members. Keep the framing tight, fastened with the right nails or screws, and make sure the load path goes straight to the walls and foundations. Add a roof deck sheathing that’s continuous and fastened with enough spikes to hold the boards flat. Cover everything with a waterproof membrane and good flashing so water doesn’t get under the shingles. Don’t forget ventilation; excess heat and moisture can weaken the deck. Inspect the roof every few years, look for cracked or missing shingles, sagging spots, or rusted metal. Clean gutters and downspouts so water doesn’t back up and cause damage. And when you do any repair, replace the damaged part with the same or better material and make sure it’s fastened correctly. That’s the basics to keep a roof solid for the long haul.

Yeah, slow and steady does the trick. One solid piece of work at a time keeps the whole thing from wobbling later on. Keep that rhythm and you’ll get a roof that lasts.
