Start with the scope
Look for a clear description of the area being repaired or replaced. Check whether removal and disposal of the old roof are included.
Two totals can cover very different work. Compare the same roof areas, materials, and tasks before deciding which estimate fits.
Name the layers and edges
The covering is the part you see. Underlayment sits beneath it, while flashing helps direct water at joints and roof openings.
Ask which products and details are included. The right scope depends on your roof, the chosen system, and local requirements.
- Roof covering and underlayment
- Flashing, pipe boots, and roof edges
- Ventilation work, if needed
- Gutters or exterior work, if included
Agree on changes
Some deck damage may only become clear after the old covering is removed. Ask how that work would be priced and approved.
Keep a written record of agreed changes. Ask who to contact when a question comes up during the job.
- What is included in the total?
- What could change after tear-off?
- How will I review added work?
- Who handles permits and cleanup?
Read the terms before you sign
Check the payment terms and any warranty documents provided with your estimate. Ask who backs each warranty and what it covers.
A calculator can help you plan a budget. It cannot inspect your roof or replace a written estimate for your property.
