Connecticut Roof Replacement Cost Guide (2025 Update)

Introduction

In this article, I’ll give you the typical costs for installing a new roof in Connecticut in 2025, for both residential and commercial buildings. I’ve spent decades researching roofing costs, and the roof cost estimates I provide here were produced by analyzing current material prices, Connecticut labor costs, and other relevant factors, including roofing project values from actual Connecticut building permit data (adjusted for the typical under-reporting). The roof systems covered here include asphalt shingles, metal roofing, slate, tile, synthetic composite, cedar shakes, and all of the common types of low-slope commercial roofing.

Roof replacement costs in Connecticut tend to be significantly higher than the national average due to a generally higher cost of living, high labor rates, regional material markups, and higher business operating costs. Construction costs in Connecticut tend to be 25% to 30% higher than the U.S. average.

Actual roof costs vary depending on roof size, roof slope, complexity, and of course the type of roof system installed. Asphalt shingles are by far the most popular residential roof covering in Connecticut, but alternatives like standing seam metal, cedar shingles and shakes, and natural slate are also relatively common. Commercial “flat” (low-slope) roofs use single-ply membranes (EPDM, TPO, PVC), modified bitumen, or spray-applied polyurethane foam roofing systems.

On average, Connecticut residential roof replacement prices in 2025 typically range from $7 per square foot for basic asphalt shingles to $44 per square foot for high-end copper roofing. This means a typical 1,700-square-foot pitched roof may cost between $11,900 and $74,800 depending on what type of material you’re using.

Commercial roofing costs are typically lower per square foot, with commercial roof replacement prices ranging, on average, from around $6 per square foot for a ballasted EPDM overlay system with no insulation included to around $25 per square foot for a 3-Ply modified bitumen system with enough insulation to meet the Connecticut R-30 energy code requirement for roofs with above-deck insulation.

The tables below provide cost information for all roof types and systems.

Climate Considerations in Connecticut

Connecticut has a humid continental climate with four distinct seasons, which affects roofing performance and roof system selection and design. Winters are cold and snowy, with temperatures frequently dropping below freezing. Summers are warm and humid, with occasional heatwaves and heavy rainfall. Precipitation is distributed throughout the year, with an average of about 50 inches per year.

Heating degree days far exceed cooling degree days in Connecticut. This means that the use of reflective “cool” roofing is not particularly important in the state, and darker roofing materials may in fact be better. And given the tendency for asphalt shingle roofs in Connecticut to develop Gloeocapsa magma colonies (roof algae), black or dark gray shingles may be best because they don’t show the black streaks and stains as much as lighter colors do.

Given these conditions, homeowners in Connecticut should consider the following:

• Asphalt shingles remain a popular and cost-effective option. Due to the state’s humid summers, algae-resistant shingles are highly recommended to prevent unsightly black streaks and biological growth, especially in shaded areas.
• Ventilation and underlayment are critical. Roof assemblies should include proper ventilation and a high-quality synthetic or ice-and-water shield underlayment to prevent ice damming and moisture intrusion during freeze-thaw cycles.
• Metal roofing offers strong performance in Connecticut’s variable climate, shedding snow easily in winter and resisting wind and moisture. PVDF-coated steel or aluminum panels are ideal for durability and color retention.
• Slate, tile, and cedar can perform well but must be installed with proper flashing and drainage details to handle snow loads and ice dams. Class A fire-rated assemblies are advisable for cedar products and the use of copper strips can help prevent algae, moss, and mildew growth.
• Insulation and attic sealing should not be overlooked. A well-insulated and sealed attic helps prevent ice dams and reduces heating costs.

Things to Keep in Mind

These roof cost estimates should be fairly accurate; I make an effort to regularly update them using current material prices and local labor data. Keep in mind that the costs listed below are averages, and actual costs can vary significantly depending on the actual configuration, accessability, and condition of your particular roof.

The residential roof cost estimates provided here are for roof replacements for roofs with a 6/12 pitch and include all standard roof components (underlayment, ice & water shield, fasteners, flashing, etc.). Steeper roofs or roofs with complex designs can increase costs by up to 30%.

Removal of an existing commercial or residential roof typically adds between $1 to $3 per square foot, and $1.50 for removal has been included in all cost estimates.

Connecticut falls within Climate Zone 5A (cool – humid), which requires a minimum R-30 continuous insulation for commercial roofs with above-deck insulation under current energy codes. However, when performing a roof recover (installing a new roof over an existing roof) this insulation requirement typically does not apply. Recover projects usually involve adding a cover board over the existing system to provide a sound substrate, followed by the new membrane.
