Why Block Island Roofing Is Unlike Anywhere Else in Rhode Island
Block Island sits 13 miles off the Rhode Island coast in open Atlantic water, accessible only by ferry, private boat, or small aircraft. This geographic isolation creates roofing challenges that are fundamentally different from mainland projects. Every shingle, every metal panel, every roll of underlayment, every piece of lumber, and every tool must cross Block Island Sound by ferry from Point Judith in Galilee, Narragansett. Every crew member must either live on the island or commute via a one-hour ferry ride each way. And the island's extreme wind and salt exposure demands materials and installation methods that far exceed mainland requirements.
The result is a roofing market that operates under constraints similar to Nantucket and Martha's Vineyard in Massachusetts. Costs run 20-30% above mainland Rhode Island rates, sometimes higher for complex projects or off-season work. Contractor availability is severely limited. Scheduling must account for ferry reservations, weather-dependent crossings, and the island's compressed construction season. Materials must be ordered further in advance to allow for transportation logistics. And the open Atlantic exposure means roofing systems face conditions that would be considered extreme by any mainland standard.
Despite these challenges, Block Island's approximately 1,000 year-round residents and hundreds of seasonal homeowners maintain a diverse housing stock that ranges from Victorian-era hotels and cottages to modern construction. Every one of these structures needs a roof that can withstand the island's relentless winds, salt spray, and nor'easter storms. This guide provides the practical knowledge you need to plan, budget, and execute a successful Block Island roofing project.

Ferry Logistics and Material Transport
Understanding ferry logistics is essential for planning any Block Island roofing project. The Block Island Ferry, operated by the Interstate Navigation Company, provides the primary link between the island and Point Judith in Galilee, Narragansett. The traditional ferry makes the crossing in approximately 55 minutes and accommodates vehicles, trailers, and cargo. A high-speed ferry operates seasonally but does not carry vehicles or building materials.
Material transport adds $800-$2,500 to a typical roofing project, depending on volume, weight, and season. A standard residential roof replacement requires 3-5 tons of materials, which typically fills a loaded pickup truck and utility trailer. Round-trip vehicle ferry tickets cost approximately $70-$130 depending on vehicle size, plus passenger fares for each crew member at approximately $25-$35 round trip. Commercial freight barges are available for larger deliveries but must be coordinated well in advance and have minimum load requirements.
Critical Ferry Planning Tips
- Book early: Vehicle ferry reservations should be made 2-4 weeks ahead in spring/fall and 4-8 weeks ahead for any summer dates.
- Backup dates: Always reserve multiple crossing dates. Weather cancellations are common, especially in spring and fall.
- Oversized loads: Trailers over 20 feet require special reservations and higher fees. Confirm maximum dimensions before loading.
- Winter schedule: The ferry runs a reduced schedule from November through April (1-2 crossings per day versus 5-8 in summer).
- Fuel and disposal: Plan for hauling old roofing materials off-island or confirm on-island disposal options with the town transfer station.
- Staging: Block Island properties often have limited staging areas. Confirm material storage locations before delivery.
Experienced Block Island contractors develop systems to minimize ferry crossings. Some pre-stage materials at mainland warehouses in Narragansett for efficient loading. Others coordinate with island-based equipment operators to reduce the need to ferry heavy machinery. The most efficient projects combine material delivery, crew transport, and equipment in a single well-planned ferry crossing, with contingency plans for weather delays.
For emergency situations, such as storm damage requiring immediate tarping, the Block Island Airport (BID) can accommodate small cargo flights, though at significantly higher cost. Helicopter transport is occasionally used for emergency materials but is prohibitively expensive for routine roofing projects. The New England Airlines service from Westerly State Airport provides passenger access but cannot accommodate roofing materials.
Block Island Cost Premium: What You'll Actually Pay
Block Island's 20-30% roofing cost premium is not arbitrary. It reflects real, quantifiable expenses that do not exist on the mainland. Understanding where the money goes helps you budget accurately and evaluate contractor quotes fairly.
| Cost Factor | Mainland RI | Block Island | Premium |
|---|---|---|---|
| Architectural shingles (per sqft) | $4.50–$8.50 | $5.75–$10.50 | +25-30% |
| Standing seam metal (per sqft) | $9.50–$16.00 | $12.00–$20.00 | +25% |
| Cedar shakes (per sqft) | $8.50–$14.00 | $10.50–$17.50 | +25% |
| Ferry/transport per project | N/A | $800–$2,500 | Fixed cost |
| Crew lodging (per project) | N/A | $500–$3,000 | Fixed cost |
| Waste disposal | $300–$600 | $500–$1,200 | +60-100% |
For a typical 1,800 square foot roof with architectural shingles, expect to pay $14,000-$21,000 on Block Island versus $10,500-$16,000 on the mainland. Standing seam metal on the same roof would cost approximately $22,000-$36,000 on Block Island versus $17,000-$29,000 on the mainland. These estimates include all island-specific surcharges including ferry transport, crew accommodations, and enhanced disposal costs.
Strategies to minimize the premium include scheduling during shoulder season when lodging costs are lower, combining your project with other Block Island work the contractor has scheduled (reducing per-project ferry and mobilization costs), ordering materials through on-island suppliers who receive bulk freight deliveries, and planning far enough ahead to avoid rush surcharges. Some contractors offer a discount of 5-10% for off-season work (November through March) when their mainland schedule slows down, though winter weather risks can offset savings.
Block Island Wind and Salt Exposure: The Most Extreme in Rhode Island
Block Island's roofing environment is the harshest in Rhode Island and among the most challenging on the entire East Coast north of Cape Hatteras. The island sits fully exposed to the Atlantic Ocean from the south and east, to Block Island Sound from the north, and to Long Island Sound from the west. There is no mainland windbreak from any direction. The Mohegan Bluffs on the southern coast rise 200 feet above sea level, creating wind acceleration effects that can increase local wind speeds by 20-30% above ambient conditions.
ASCE 7-22 wind speed maps classify Block Island in the 130-150 mph ultimate design wind speed zone, the highest category in Rhode Island and significantly above the 110-130 mph range for most of the mainland. During Hurricane Bob in 1991, Block Island recorded some of the highest wind speeds in New England. Nor'easters routinely produce sustained winds of 50-70 mph with gusts exceeding 90 mph. Even on calm days, average wind speeds on Block Island are 15-20% higher than equivalent mainland locations.
Salt exposure on Block Island is continuous and severe. Unlike mainland coastal communities where salt spray diminishes rapidly with distance from shore, Block Island's narrow geography means every structure on the island is within the heavy salt spray zone. Salt accelerates corrosion of metal fasteners, degrades organic materials like wood and asphalt, and creates a harsh chemical environment that demands marine-grade components throughout the roofing system.
Materials to AVOID on Block Island
- 3-tab shingles (60 mph wind rating, 10-15 year lifespan on BI)
- Galvanized steel (corrodes in 3-7 years in extreme salt)
- Standard galvanized fasteners and flashings
- Painted steel standing seam (salt penetrates paint failures)
- Standard wood shakes without marine treatment
- Vinyl or plastic vents and accessories
Recommended Materials for Block Island
- Standing seam aluminum (140+ mph, salt-immune)
- Impact-resistant shingles (130+ mph rated)
- Marine-grade stainless steel fasteners throughout
- Aluminum or stainless flashing components
- Synthetic underlayment (superior wind resistance)
- Copper ridge vents and accessories
The combination of wind and salt creates synergistic degradation. Wind-driven salt spray penetrates every gap, seam, and fastener hole. Materials that perform well individually against wind or salt may fail when both forces act simultaneously. This is why marine-grade specifications are essential for Block Island, not optional upgrades. Contractors experienced with Block Island understand this reality; those new to island work may underestimate the severity and specify materials that will fail prematurely.

Material Recommendations for Block Island
Material selection on Block Island is not just about aesthetics or budget; it is fundamentally a durability decision that determines how many years (and expensive island re-roofing cycles) you can avoid. Every extra year of lifespan is amplified in value by the island's 20-30% cost premium. A material that lasts 50 years on Block Island saves you the full cost of one or two complete re-roofing projects compared to a material that lasts only 20 years.
Standing Seam Aluminum
$12.00–$20.00/sqft on Block Island · 40-70 year lifespan · Best overall choice
Marine-grade aluminum standing seam is the definitive choice for Block Island. Aluminum is naturally immune to salt corrosion, eliminating the single greatest threat to roofing longevity on the island. The concealed fastener system provides 140+ mph wind resistance, exceeding even Block Island's extreme ASCE 7 requirements. The interlocking panel design creates a continuous weather barrier with no exposed penetration points for wind-driven rain or salt spray to exploit.
At 40-70 years of lifespan in Block Island conditions, aluminum standing seam typically outlasts two or three generations of shingle roofs. Given the island premium on every re-roofing project, the lifetime cost of aluminum is often lower than the cheapest alternatives when calculated over a 50-year period. Specify 0.032" or thicker aluminum panels, marine-grade stainless steel clips, and aluminum trim throughout for maximum longevity.
Impact-Resistant Architectural Shingles
$5.75–$10.50/sqft on Block Island · 18-24 year lifespan · Best value option
Class 4 impact-resistant architectural shingles rated for 130+ mph winds represent the best value-oriented choice for Block Island. These shingles feature SBS-modified asphalt for enhanced flexibility in freeze-thaw conditions, reinforced nailing zones to resist wind uplift, and algae-resistant granules. The 130+ mph wind rating meets or exceeds the ASCE 7 requirements for most Block Island locations.
However, shingle lifespans are significantly reduced on Block Island compared to mainland installations. Expect 18-24 years versus the 25-30 year mainland expectation, and as little as 15-18 years on the most exposed southern and eastern elevations facing the open Atlantic. Use 6-nail fastening patterns (not the standard 4-nail) with stainless steel ring-shank nails. Hand-seal all tabs on wind-exposed elevations. Apply a starter strip with enhanced adhesive on all eave and rake edges.
Cedar Shakes (with Marine Treatment)
$10.50–$17.50/sqft on Block Island · 20-30 year lifespan · Traditional island aesthetic
Cedar shakes are part of Block Island's architectural tradition, giving many island structures their distinctive weathered gray appearance. When properly treated with marine-grade preservatives and installed with stainless steel fasteners, cedar shakes can last 20-30 years on Block Island. The natural wood resists wind well when properly fastened and develops a patina that many island homeowners prefer.
The downside is maintenance. Block Island's intense salt and wind exposure requires professional maintenance every 1-2 years, including reapplication of preservative treatments, replacement of split or displaced shakes, and cleaning of moss and lichen that thrive in the island's damp maritime climate. Properties in the Block Island Historic District may require cedar shakes to maintain the traditional character, even when other materials might be more practical. Budget $500-$1,500 annually for ongoing maintenance.
Finding and Managing Block Island Roofing Contractors
The limited contractor market is one of Block Island's biggest roofing challenges. No dedicated roofing companies are based on the island. The handful of general contractors who live on Block Island year-round can handle minor repairs and emergency work, but full roof replacements are almost always performed by mainland Rhode Island contractors who bring crews and materials across by ferry.
When selecting a contractor for Block Island work, the single most important qualification is specific island experience. A contractor who has completed 5-10 or more Block Island projects understands the ferry logistics, on-island material staging, town permitting requirements, and the enhanced installation specifications necessary for the island's extreme exposure. A mainland contractor with no island experience, regardless of their mainland reputation, will face a steep learning curve that often results in project delays, cost overruns, and specifications that underperform in island conditions.
Block Island Contractor Evaluation Checklist
- Active RI Contractors Registration Board license
- Minimum 3-5 completed Block Island roofing projects (ask for addresses and references)
- Understanding of ferry logistics and material transport planning
- Relationships with on-island equipment operators and suppliers
- Familiarity with Town of New Shoreham permitting and building code
- Marine-grade material specifications in the proposal (not standard mainland specs)
- Contingency plan for weather-related ferry cancellations in the contract
- Clear waste removal plan (off-island haul or confirmed transfer station acceptance)
- Adequate insurance coverage including marine transit and island operations
- Written warranty that covers return trips for warranty service
Plan well ahead. The best Block Island contractors book projects 3-6 months in advance, particularly for the preferred spring and fall windows. Getting three competitive quotes can take weeks given the limited pool of experienced contractors. Start the quote process at least 4-6 months before your target installation date.
Payment structures for Block Island projects often differ from mainland norms. Expect a larger upfront deposit (25-35% versus 10-20% on the mainland) to cover material purchases and ferry reservations. Progress payments may be structured around ferry delivery milestones rather than installation phases. Retain 10-15% until final inspection and punchlist completion, just as you would on the mainland.
Seasonal Scheduling for Block Island Roofing
Block Island's roofing season is compressed by island logistics, weather patterns, and the tourism economy. Unlike the mainland, where roofing can proceed year-round with some seasonal adjustments, Block Island's schedule is constrained by ferry availability, crew accommodation, and the island's economic calendar.
Best: Spring (Late April - Mid-June)
Ferry service expanding from winter schedule. Lodging available and affordable. Weather warming with moderate wind. Contractors eager for work after slow winter. Complete before summer tourist season peaks. Rental properties can be offline without revenue loss. Primary downside: spring nor'easters can disrupt scheduling in April and May.
Good: Fall (September - Mid-November)
Tourism winding down. Ferry service still robust. Stable weather in September and October. Lodging becoming available and affordable. Complete before winter storm season. Primary downside: hurricane season extends through November, and nor'easters become more frequent in late October. Shorter days limit work hours as season progresses.
Avoid: Summer (Mid-June - August)
Ferry reservations nearly impossible to secure for vehicles and trailers. Crew lodging unavailable or prohibitively expensive ($300-$600/night). Rental properties at peak revenue so homeowners cannot take them offline. Island infrastructure strained by tourism. Noise and disruption complaints from neighbors and guests. Costs can be 40-50% above baseline.
Challenging: Winter (December - March)
Reduced ferry schedule (1-2 crossings per day). Frequent weather cancellations. Short daylight hours. Cold temperatures affect material installation. Crew lodging extremely limited. However, contractor rates may be 5-10% lower and scheduling flexibility is greatest. Best for year-round residents who can monitor progress and provide local coordination.
For rental properties, the ideal approach is to schedule the project in the gap between summer rental season and winter. Many Block Island property managers recommend the first two weeks of September or the last two weeks of May as optimal windows that avoid both the peak tourist season and the worst weather.
Block Island Historic District and Permitting
Block Island (Town of New Shoreham) has its own building department, building code enforcement, and historic district regulations that differ from mainland Rhode Island municipalities. The Block Island Historic District encompasses a significant portion of Old Harbor and the surrounding area, including many of the island's iconic Victorian-era hotels and residential structures.
Properties within the historic district must receive approval from the Block Island Historic District Commission before any exterior work, including roof replacement. The commission reviews proposed materials for compatibility with the district's architectural character. Traditional materials such as cedar shakes, natural slate, and standing seam metal in appropriate colors are generally approved. Modern materials must demonstrate visual compatibility from the public right-of-way. Applications should be submitted well in advance as the commission meets on a set schedule.
All Block Island roof replacements require a building permit from the Town of New Shoreham Building Department, regardless of historic district status. The permit process includes plan review, fee payment (typically based on project value), and inspection at completion. FEMA flood zone properties, which include much of the island's coastline, face additional requirements for wind resistance and elevation that may affect roofing specifications.
Environmental regulations are also more stringent on Block Island than on the mainland. The island's water supply, fragile coastal ecosystems, and limited waste processing capacity mean that material disposal, staging, and construction runoff are subject to oversight. Contractors must plan for proper containment and removal of old roofing materials, particularly if they contain asbestos (common in pre-1980 construction).
Insurance Considerations for Block Island Roofs
Block Island properties face significant insurance challenges. The island's extreme wind exposure and coastal flood risk place it in the highest risk category for most insurance carriers. Many standard homeowners insurance companies either decline to insure Block Island properties or charge substantial premiums that reflect the elevated risk. The Rhode Island FAIR Plan provides coverage of last resort for properties unable to obtain standard market insurance.
Roof condition is a critical factor in insurance availability and pricing for Block Island properties. A new, wind-rated roof can significantly improve your insurability and reduce premiums. Conversely, an aging roof with visible wear can trigger non-renewal notices. Insurers increasingly require wind mitigation inspections for coastal Rhode Island properties, and Block Island homes face the most scrutiny.
Wind and named-storm deductibles on Block Island policies are typically 2-5% of the insured value, significantly higher than the flat-dollar deductibles common on mainland policies. For a $500,000 Block Island home, a 3% wind deductible means $15,000 out of pocket before insurance pays. This makes proactive roof maintenance and wind-rated materials even more important, as the financial consequence of wind damage falls heavily on the homeowner through high deductibles.
