Roof Replacement Cost Calculator
Not sure of your roof size? Most Rhode Island homes are 15 to 25 squares. We measure every roof during a free estimate. Decking can only be confirmed after tear-off; a full re-deck uses about 3 sheets per square.
Why Decking Is Priced at $100 per Sheet
Many New England homes have roof decking that has been through decades of leaks, ice dams, and poor ventilation. Some have old board sheathing or thin plywood that will not hold nails properly. None of that is visible until the old roof comes off.
Instead of padding every estimate for a worst case, we replace only the decking that actually needs it, at a set price of $100 per sheet, and show you the damage before it is covered. You pay for what your roof needs and nothing more.
What Every GCR Roof Includes
- Complete tear-off and disposal of the old roof
- Inspection of the decking once the roof is open
- Ice and water shield at eaves, valleys, and other vulnerable areas
- Synthetic underlayment over the rest of the roof deck
- New flashing at walls, chimneys, skylights, and penetrations
- Ventilation designed for your attic
- Architectural asphalt shingles installed to manufacturer specifications
- Final inspection and job-site cleanup
Every Roof Is Designed for the Home
A roof is part of a system. How well it performs depends on how it handles water, air, and moisture at every edge and penetration, not just on the shingles. That is why we do not use one roof design for every house.
Before we quote, we look at how your home is built and where it sits: attic ventilation and moisture, how wall and chimney flashing is detailed, ice dam history, and exposure to wind-driven rain, especially near the water. When it helps, we use infrared thermal imaging to find hidden moisture before we start. The result is a roof designed for your home and your location, built to last.

Frequently Asked Questions
What is a roofing square?
A roofing square is 100 square feet of roof surface. Most Rhode Island homes we work on are between 15 and 25 squares, and 18 squares is the size we see most often.
How much does a new roof cost in Rhode Island?
For a standard architectural asphalt shingle roof, our price is typically $600 to $650 per square. A typical 18-square roof runs about $10,800 to $11,700, plus any plywood decking that needs to be replaced.
Why is plywood decking priced separately?
Nobody can see the condition of roof decking until the old shingles are removed. Many older New England homes have decking that is rotted, delaminated, or too thin. Instead of padding every estimate, we replace only what is needed at $100 per sheet and show you what we found.
How much decking will my roof need?
It depends on the age of the home and past leaks. Some roofs need none, some need a few sheets around chimneys, valleys, and eaves, and some older homes need full replacement. A full re-deck uses roughly 3 sheets per square, or about $313 per square.
Do I need a permit to replace my roof in Rhode Island?
A roof replacement typically requires a building permit from your town. We pull the permit and schedule any required inspections as part of the job.
Do these prices apply to metal or flat roofs?
No. The prices on this page are for architectural asphalt shingle roofs. Metal, flat, and low-slope roofs are designed and quoted per project.
