Quick answer: New construction roofing differs from a re-roof in three key ways — it requires coordination with the builder’s timeline, inspection at the decking stage before shingles go on, and manufacturer-certified installation to keep warranties valid from day one. In metro Atlanta, where new subdivisions and custom builds are common from Woodstock to Cumming, getting this stage right prevents 90% of the leak calls roofers see in a home’s first five years.
Why New Construction Roofing Isn’t Just “Installing Shingles”
Homeowners often assume a new roof on a new house is the simplest job in roofing. In practice, it’s one of the most sequence-dependent. The roofing crew is working around framers, electricians running through the attic, and HVAC installers — all before the house is weathertight. Get the order wrong and you end up with:
- Decking exposed to rain for too long, causing warping before shingles ever go down
- Improperly placed roof penetrations for vents, flues, and skylights that get patched instead of properly flashed
- Ventilation systems installed without regard to the attic’s actual airflow needs, leading to moisture problems years later
A roofing contractor experienced in new construction coordinates directly with the general contractor’s schedule, inspects the decking before installation, and confirms manufacturer specifications are met — not just close enough. That last point matters more than most builders realize: shingle and underlayment warranties from manufacturers like CertainTeed require installation that meets their standards, and skipping that step can void coverage the homeowner doesn’t find out about until they file a claim.
What to Ask Your Builder or Roofer Before the Roof Goes On
Whether you’re building custom in Alpharetta or buying in a new Kennesaw subdivision, ask these questions before roofing work begins:
- Who is actually installing the roof? Builders often subcontract roofing, and quality varies widely between crews even under the same builder’s name.
- Is the installer manufacturer-certified? Manufacturer certification, for example, means the crew has met specific training and workmanship standards required for full warranty coverage — ask to see current proof, not just a logo on their site.
- What’s the decking inspection process? Decking should be inspected for moisture damage, proper nailing pattern, and structural soundness before any underlayment goes down — not assumed fine because it’s new lumber.
- How is ventilation being handled? A new roof with inadequate ridge or soffit ventilation will trap heat and moisture in the attic regardless of how good the shingles are.
These aren’t gotcha questions — a reputable roofer will have straightforward answers ready, because they already follow these steps as standard procedure.

Frequently Asked Questions
Does a new construction roof need a separate inspection from the home’s final walkthrough?
Yes. The roof decking and initial waterproofing should be inspected before shingles are installed — issues at that stage are far cheaper to fix than after the roof is fully closed in, and they’re often invisible during a standard final walkthrough since the finished roof covers them.
Can I choose my own roofer instead of using the builder’s assigned subcontractor?
In most custom-build contracts, yes, though production builders in larger subdivisions may require using their designated subcontractor. It’s worth asking early in the process, since a change is much easier before the roofing line item is finalized in the build contract.
Does new construction roofing come with the same warranty as a re-roof?
It should, provided the installation meets manufacturer certification requirements. This is exactly why asking whether your installer is manufacturer-certified matters — it’s the difference between full warranty coverage and a voided claim later.
