What Should Be Included in a New Roof Installation Estimate? Shingles, Underlayment, Flashing, Ventilation & Warranties
New Roof Estimates in Macon, GA: What Should Be in There and What to Watch For

Macon homeowners comparing new roof installation estimates often find that proposals for what sounds like the same scope vary more than expected, and that the line items listed in each estimate are not always the same. Some proposals include underlayment. Some assume it. Some include flashing replacement. Some do not address it. Some include ventilation assessment. Most skip it entirely. The price comparison that looks straightforward on the surface is comparing different actual scopes, and understanding what each line item means changes how Macon homeowners read what they are being offered.

Shingles: Product Specification Is the First Comparison Point
A new roof estimate for a Macon home should specify the shingle product by name, including the manufacturer, product line, and wind resistance rating. Georgia wind codes require shingles to meet certain wind resistance ratings for Bibb County, and the specific product determines what warranty tiers are available from the manufacturer. An estimate that says architectural shingles without specifying the product line is an estimate that cannot be compared accurately with one that specifies an Owens Corning Duration or equivalent product by name.
Impact resistance rating matters in Macon's storm corridor. A Class 4 impact-rated shingle costs more than a standard architectural shingle but holds up through hail events that damage standard products and may qualify for homeowner insurance premium discounts. BTD Roofing & Outdoors discusses product options during the free estimate based on the Macon homeowner's priorities and budget.
Underlayment: The Layer Beneath the Shingles
Every new roof installation in Macon should include new underlayment. A proposal that does not address underlayment is assuming the existing underlayment stays in place under the new shingles, which defeats much of the purpose of the new roof. Underlayment is the secondary water barrier that protects the deck if shingles are lost or displaced during a storm event.
Synthetic underlayment outperforms felt in Macon's climate. Felt absorbs moisture, can wrinkle and buckle under shingles, and degrades faster under Georgia UV exposure than synthetic alternatives. A Macon estimate that specifies felt underlayment is specifying a lower-performance product than synthetic, which is worth noting in the comparison. BTD Roofing & Outdoors uses appropriate underlayment for the specific scope on every Macon roof installation.
Flashing: The Detail Work That Determines Leak Resistance
Flashing replacement is the line item most commonly missing or assumed in Macon new roof estimates. Flashings at pipe penetrations, chimney bases, wall transitions, and valleys are the points where most residential leaks originate. Installing new shingles over original flashings that are 15 or 20 years old, corroded, or improperly integrated, is a new roof with the same failure points as the old one.
A Macon roof installation estimate should specify what happens to flashings: are they replaced? Assessed and replaced where warranted? Left in place? The answer changes the scope and the leak resistance of the finished roof. BTD Roofing & Outdoors addresses flashing condition as a specific line item in every Macon installation estimate rather than leaving it unstated.
Ventilation: The Item That Most Macon Estimates Skip
Attic ventilation is almost never addressed in a standard Macon roofing estimate, but it directly affects how long the new shingles last. An under-ventilated attic in Middle Georgia's summer climate bakes shingles from below while UV works from above, shortening the service life of the new roof before it has reached anything close to its expected age. Adding ridge vents or improving soffit intake during the roof replacement is a legitimate scope item that most Macon contractors do not raise.
BTD Roofing & Outdoors assesses attic ventilation as part of the new roof consultation for Macon homeowners. If the ventilation is adequate, that finding is shared. If it warrants improvement, the option is presented with the associated cost so the Macon homeowner can make an informed decision.
Warranties: Two Separate Coverages on Every New Roof
A new roof in Macon carries two separate warranties: the manufacturer material warranty covering the shingle product, and the workmanship warranty covering how it was installed. These are separate documents with separate coverage terms and separate claims processes. An Owens Corning Preferred Contractor like BTD Roofing & Outdoors can offer enhanced manufacturer warranty tiers that standard installers cannot access. The workmanship warranty duration varies by contractor and is worth asking about directly.

Frequently Asked Questions About New Roof Installation Estimates in Macon, GA
What should a new roof installation estimate include for a Macon home?
A complete Macon new roof estimate should specify the shingle product by manufacturer, product line, and wind resistance rating; the underlayment type and coverage; the flashing scope including what is replaced versus left in place; any ventilation assessment or improvements; cleanup and disposal; and the workmanship warranty terms alongside the manufacturer warranty that comes with the specified product.
Why do new roof estimates in Macon vary so much in price?
Price variation in Macon roof estimates reflects different actual scopes rather than just different labor rates. Proposals that exclude underlayment replacement, flashing assessment, or ventilation evaluation are cheaper because those items are not included. A proposal that addresses the full scope costs more but delivers a more complete installation. Comparing estimates without confirming the scope of each item produces a price comparison that is not comparing equivalent work.
What is the difference between synthetic underlayment and felt in Macon?
Synthetic underlayment outperforms felt in Macon's climate. Felt absorbs moisture and can wrinkle and buckle under shingles. Synthetic underlayment is moisture-resistant, tears less during installation, and degrades more slowly under Georgia UV exposure than felt alternatives. A Macon installation estimate specifying felt underlayment is specifying a lower-performance secondary water barrier than synthetic, which is worth noting in any side-by-side estimate comparison.
Should flashing be replaced during a new roof installation in Macon?
Flashing at pipe penetrations, chimney bases, wall transitions, and valleys should be assessed and replaced where warranted during a new Macon roof installation. Installing new shingles over original flashings that are corroded, improperly integrated, or past reliable service life installs a new roof with the same leak vulnerability points as the old one. BTD Roofing & Outdoors addresses flashing condition as a specific line item in every Macon installation estimate.
What warranties does an Owens Corning Preferred Contractor offer in Macon?
As an Owens Corning Preferred Contractor, BTD Roofing & Outdoors can offer enhanced manufacturer warranty tiers on qualifying Macon roof installations that are not available through standard installers. These enhanced tiers extend coverage on the material itself beyond the base warranty. The workmanship warranty from BTD Roofing & Outdoors covers the installation quality separately from the manufacturer material warranty.
