Short answer: compare scope, not totals. Check tear-off versus layover, the per-sheet decking price, whether flashing is new or reused, ventilation, permits, warranty terms and cleanup. A cheap quote is usually a shorter list, not a better deal.
The line items that should be there
- Tear-off and disposal. How many layers are being removed, and is the dumpster included.
- Decking allowance. A per-sheet price agreed before the roof is opened. Nobody can see the decking until the old roof is off, so this number must be set in advance.
- Underlayment. Named product. Synthetic or felt matters, and so does ice and water shield in valleys and at penetrations.
- Flashing. The word to look for is new. Reused chimney and wall flashing on a new roof is the most common hidden shortcut in this trade.
- Ventilation. Ridge vent, and critically whether soffit intake is being corrected if it is inadequate.
- Shingle product and color by name and line, not just a brand.
- Permits and who pulls them.
- Cleanup including how many magnet passes.
- Warranty terms, both manufacturer and workmanship, in writing with a duration.
What a missing line item costs you
If the estimate does not mention decking, you will be negotiating a price with the roof open and your house exposed. If it does not say new flashing, assume the old flashing is being reused and plan for a leak in three years. If it does not mention ventilation and your attic is under vented, you are installing a new roof into the same conditions that aged the last one early.
Red flags
- A one page quote with a single number and no breakdown
- No named shingle product line
- Any mention of waiving, absorbing or working around your deductible, which is illegal in Texas
- Pressure to sign today for a price that expires tonight
- A large cash deposit requested before materials are delivered
- No certificate of insurance offered
Questions worth asking before you sign
- What is the per sheet decking price, and how is it documented?
- Is all flashing new, including at the chimney and wall terminations?
- Are you manufacturer certified, and will the warranty be registered in my name?
- Is the workmanship warranty transferable if I sell?
- Who is physically on my roof, your crew or a subcontractor?
- Can I see a current certificate of insurance?
If a contractor cannot answer the last one, that is your answer. Texas does not require a state roofing license, which makes insurance certificates and association membership the verifiable credentials that remain.
