Planning and Design: Creating a Blueprint for Your Roof

You’ve got your blueprints laid out and your framing is done, now it’s time for the roof – one of the most important parts of your build. A roof done right will protect your home for decades, while a roof done wrong will lead to leaks, drafts, and repairs down the line. In this guide, we’ll walk you through the roof construction process from start to finish. We’ll go over material selection, rafters and trusses, roof decking, underlayment and waterproofing, shingles and metal roofing, skylights and ventilation. With the right materials and proper technique, you’ll end up with a sturdy, weather-tight roof that ties your whole house together. So grab your toolbelt and let’s get ready to raise that roofline!

Roof Framing: Constructing the Roof Structure

The first step to constructing your roof is planning and design. You’ll want to hire an architect or roofing contractor to assess your needs and create a blueprint that outlines the specifics of your new roof. Things like:

– Roof type (gable, hip, flat, etc.)

– Roofing material (asphalt shingles, metal panels, tile, slate, etc.)

– Number of stories and overall square footage

– Local building codes and requirements

– Your budget

Once you have a design and blueprint in place, it’s time to obtain the necessary permits from your city or county. This helps ensure your new roof will be structurally sound and up to code.

With permits approved, you can start purchasing all the materials and supplies. This includes the roofing material itself, along with roofing felt or paper, flashing, vents, trusses or rafters, and roofing nails or screws. Be sure to order everything at once to avoid delays.

The final step before installation is preparing the site. This means inspecting and repairing any damage to the existing roof structure or sheathing. You’ll also want to clear the area around your home of any debris that could get in the way.

When the blueprint is set, permits approved, materials purchased, and the site prepped, you’re ready for the roofing crew to start tearing off the old roof and installing your new one. In no time, you’ll have an attractive new roof overhead—and peace of mind that it’s been done properly from start to finish.

Roofing Materials: Choosing and Installing Shingles, Tiles, or Metal Roofing

Once the walls are up, it’s time to frame in the roof. This involves installing a ridge board at the peak and rafters that extend down to the top plates of the walls. The rafters should be spaced about 16 to 24 inches apart, depending on the type of roofing material you’ll be using.

–   Measure the distance between the walls to determine the length of the ridge board and rafters. Cut the ridge board, rafters, and any supports to size.

–   Install the ridge board at the peak, securing it to the top wall plates. The ridge board should run along the length of the roof.

–   Attach one end of a rafter to the ridge board at the peak. Then attach the other end to the top plate of a wall, keeping the rafter level. Repeat with the remaining rafters, spacing them evenly.

–   Add collar ties between the rafters for extra support. Collar ties are horizontal boards that connect the rafters together about halfway down from the ridge board.

–   You may also want to install gable studs, which are vertical studs that frame in a triangular section at each end of the roof. The gable ends will be covered by the siding and trim.

With the basic frame in place, you’ll be ready to install roof sheathing and eventually roofing materials like shingles or metal panels. The framing is the foundation, so make sure everything is level, securely fastened, and built to code in your area. If you take your time, you’ll end up with a roof that’s structurally sound for years to come.
