Compare the work before comparing the total. Two roof estimates can name the same Owens Corning shingle and still include different tear-off work, flashing, ventilation, wood repairs, and warranties. A useful estimate makes those differences visible before you sign.
For a Gainesville home with a main roof, an attached porch, and an older addition, even the phrase “full roof replacement” needs a boundary. Ask each contractor to mark the included roof sections on the same photograph or drawing. Then work through the written scope together. You should be able to explain what you are buying without translating roofing shorthand yourself.
1. The roof areas included in the price
Start with the house, garage, porches, and additions. Confirm which surfaces the contractor measured and which surfaces the estimate excludes. A low-slope porch might need a different roofing system and a separate scope.
Ask the contractor to distinguish measured roof area from material ordered for cuts and waste. Those quantities serve different purposes. If one estimate is much larger, ask where the difference comes from. A marked roof drawing can settle that conversation faster than debating a single square-foot figure. Keep the drawing with the estimate so a later revision has a clear starting point.
2. The exact shingle and accessory products
“Owens Corning architectural shingles” identifies a manufacturer and a broad type of product. Ask for the full product name and selected color. Then identify the starter shingles, hip and ridge shingles, and underlayment separately.
Brehm uses Owens Corning for asphalt shingle roofing in Gainesville. Your proposal should still identify the products for your particular house. If a substitution becomes necessary, ask for the new product details before approval. A color that looks similar in a brochure may belong to a different shingle line with different documentation.
3. Tear-off and disposal
Ask what the contractor expects to remove and how that expectation was established. Existing layers, an older repair, or roofing over an addition may affect the removal work. The estimate should explain how an unexpected condition will be handled.
Confirm whether disposal, hauling, and equipment removal are included. Ask where the container will sit and when it should leave. On a driveway used for daily school or work trips, that arrangement can matter as much as the first delivery time. Discuss access before equipment is parked where a vehicle needs to exit.
4. Decking repairs and additional charges
Roof decking is the surface beneath the roofing materials. Some of its condition may remain concealed until removal begins. Ask what wood replacement, if any, is included in the base price and how additional repairs will be documented.
Request the unit used for pricing, the labor included, and the approval process. “Wood extra” leaves too much unresolved. A clearer explanation identifies the material, the rate or pricing method, and who will contact you with photographs. Confirm whether trim, fascia, and structural repairs fall under separate items so one allowance does not appear to cover everything.
5. Flashing and roof penetrations
List the places where something passes through the roof or where the roof meets another surface. These may include plumbing pipes, a chimney, sidewalls, skylights, and a porch transition. Ask what happens at each location.
The useful distinction is whether a component will be replaced, retained after inspection, or excluded. A general sentence about “flashing as needed” makes comparison difficult. Ask for the scope to identify any wall or siding work necessary to complete a repair, including who performs it and whether finishing work is included. That avoids discovering a second trade requirement halfway through the project.
6. The ventilation assessment
A proposal that lists ridge vent should explain why that approach fits the house. Ask what attic areas were assessed, what intake is available, and whether an addition has a separate attic space.
You do not need to design the ventilation yourself. You need to know whether the contractor evaluated the existing arrangement and what the quoted work changes. Ask for the proposed vent locations on the roof drawing. If the home has spray foam at the roof deck, disclose it before the ventilation scope is finalized; that condition needs a specific review rather than a routine vent replacement decision.
7. Permit responsibilities and completion steps
Identify who handles the applicable permit and inspections, what fees the quote includes, and which office has jurisdiction over the address. Use the or as starting points for the appropriate authority.
Also define completion. Installation, cleanup, an inspection, and final paperwork may happen at different times. Ask which milestones control invoicing and how remaining items will be recorded. Put any deadline that matters to your household into the discussion before signing.
8. The named warranties and exclusions
Request the manufacturer warranty by name and the contractor's workmanship coverage in writing. Ask what is included in this price and what, if anything, is optional. Keep the actual documents alongside the proposal.
Avoid comparing warranties by the biggest number in the sales presentation. Ask who handles a reported problem, what records you should retain, and which conditions or exclusions you should read. If a contractor describes an enhanced Owens Corning warranty, ask for the applicable eligibility requirements and confirmation for your installation. The manufacturer name alone does not establish the warranty included in your quote.
A comparison sheet you can use
Create a page with three columns: scope item, contractor A, and contractor B. Enter the eight items above. Write “not stated” wherever an estimate is silent; do not assume silence means included. Send each contractor the unanswered items and request a revised written scope.
Only compare final totals after the scope is clear. You may still choose different materials or coverage, but you will understand what explains the price difference. Bring that marked-up sheet to Brehm Roofing's contact team when you request an estimate for your Gainesville home.
