Does a new roof installation cost less than a replacement since there's no tear-off?

Removing an old roof is only one part of a replacement job's cost, so the difference isn't as large as it might seem. New construction still involves full decking, underlayment, and material installation.

Can the same contractor handle both my addition's roof and matching it to my existing roof?

Yes, and it's generally a good idea. A contractor doing the tie-in work can make sure the new section matches the existing roofline and shingle pattern instead of leaving a visible seam.

Do I need to hire the roofer or does my general contractor handle that?

It depends on the project. Some homeowners hire the roofer directly and coordinate scheduling with their GC; on larger new builds, the roofing is often subcontracted by the general contractor as part of the overall build.

New roof installation for additions and new construction in Hartford Metro

Putting a roof on new construction, whether that's a full new build, an addition, or a detached garage, is a different job than tearing off and replacing an existing roof. There's no old roofing to strip and haul away, but there's more coordination involved: working off the builder's plans, matching pitch and material to the rest of the structure (or to code, on a standalone build), and timing the work around the framing and sheathing schedule so the building gets weathertight on schedule.

For additions in particular, tying the new roof into the existing roofline cleanly, so flashing and shingle lines match up and don't create a future leak point, takes some care. Contractors who do a lot of new construction work are used to coordinating directly with a general contractor or builder rather than working off a standalone homeowner request.

What it costs

Cost on new roof installation tracks with the square footage being roofed, the roof's complexity (number of valleys, dormers, and pitch changes), the material chosen, and the decking work involved. Because there's no tear-off, some of the labor that goes into a replacement job isn't part of new construction, but coordinating with a build schedule can add its own cost if timelines shift.
