How to compare Houston shingle roof replacement scopes

Look for a clear description of tear-off, decking, underlayment, flashing and the proposed shingle line. Ask how changes will be documented.

Ask how decking work will be documented and which roof areas are included. Confirm that the Houston estimate identifies the actual materials and the person who will communicate any changes.

Why compare scope and not only price

Two Houston shingle proposals can show different totals because they include different work. Comparing scope line by line shows what each price actually covers.

What a clear scope names

Tear-off of existing roofing and how many layers are included.
Decking: how damaged or rotted sheathing will be found, priced and approved.
Underlayment and any water barrier at the eaves, valleys and penetrations.
Flashing at walls, chimneys, skylights and pipes.
The specific shingle line, color and accessories being proposed.
Ventilation components and ridge details.
Cleanup, magnet sweep and disposal.

Ask how changes are handled

Hidden decking problems are common once old shingles come off. Ask whether the proposal uses an allowance or a unit price, who will approve extra work and how it will be documented in writing.

Put proposals side by side

Match the same items across proposals. A lower number that leaves out flashing or underlayment is not the same offer as a higher one that includes them.
