New roof installation is the right term for first-time roofing: new construction, additions, or rebuilds where there is no existing roof to remove. Replacement applies when an existing roof is removed and a new one installed in its place. The distinction matters for permit scope, structural review, and warranty timing. New installations are typically planned alongside framing inspection, with the roofing crew sequenced after structural sheathing is complete and before mechanical and electrical rough-in. Replacement projects follow a different workflow: tear-off, decking inspection, repair allowance, then install. In both cases, the underlayment, flashing details, ventilation plan, and fastener schedule should be specified in writing before crews mobilize.
The most common pre-install oversight is mismatched material to roof geometry — choosing a heavy tile system on framing not engineered for the weight, or selecting a low-slope membrane for a roof with insufficient drainage. The framing review is a non-negotiable step. Equally common is skipping the ventilation calculation, which determines whether the roof traps heat (shortening shingle life) or stays in spec. We work through these decisions with the homeowner before ordering material, not after.
Yes. New installations in Los Angeles County require a permit and are typically integrated into the broader building permit for the construction project. The roofing scope is part of the inspection sequence.
Yes, and it is often the most cost-effective sequencing because the labor for flashing and conduit penetrations is absorbed into the install rather than performed twice.
Manufacturer material warranties typically run 25–50 years depending on product, with separate labor warranties from the contractor. Both should be in writing and registered with the manufacturer at completion.
