Block Island & Aquidneck
Island Roofing Guide

Why Island Roofing Is Different in Rhode Island

Rhode Island's two major island areas -- Block Island (New Shoreham) and Aquidneck Island (Newport, Middletown, and Portsmouth) -- present roofing challenges that are fundamentally different from mainland communities. While every Rhode Island home contends with coastal weather to some degree, island properties face amplified versions of every coastal threat: stronger winds with no inland buffer, salt air exposure from 360 degrees instead of one direction, limited contractor availability, logistical constraints on material delivery, and regulatory layers including Historic District Commission oversight and CRMC coastal management rules.

Block Island, officially the Town of New Shoreham, sits approximately 12 miles south of the Rhode Island mainland in the open Atlantic Ocean. With a year-round population of roughly 1,000 that swells to 15,000-20,000 during summer months, the island has extremely limited construction infrastructure. There are no big-box home improvement stores, no roofing supply distributors, and only a handful of resident contractors. Every bundle of shingles, every sheet of plywood, and every piece of flashing must cross Narragansett Bay on the ferry from Point Judith (Galilee) in Narragansett. When a nor'easter shuts down ferry service -- which happens multiple times each winter, sometimes for days at a stretch -- construction stops entirely.

Aquidneck Island, connected to the mainland by the Claiborne Pell Newport Bridge (Route 138) and the Sakonnet River Bridge (Route 24), is far more accessible. Newport, Middletown, and Portsmouth collectively house over 40,000 residents and have a robust local contractor market. However, Aquidneck Island still faces extreme coastal exposure. The island is surrounded by Narragansett Bay to the west, the Sakonnet River to the east, and the open Atlantic to the south. Newport's Ocean Drive and Cliff Walk properties are among the most wind-exposed residential sites in all of New England. The city also contains one of the most stringent Historic District Commissions in Rhode Island, with oversight covering hundreds of colonial-era, Federal, and Gilded Age structures.

Understanding the specific challenges of each island is essential for planning a successful roofing project. The cost premiums, scheduling requirements, material specifications, and regulatory hurdles vary significantly between Block Island and Aquidneck Island, and both differ markedly from mainland Rhode Island. This guide breaks down everything you need to know before replacing or repairing a roof on either island.

Block Island: Ferry Logistics and Material Delivery

The single biggest cost driver for Block Island roofing is logistics. The Interstate Navigation Company operates the traditional ferry between Point Judith (Galilee) and Old Harbor on Block Island. The freight ferry accommodates trucks and oversized vehicles, but space is limited and reservations fill quickly, particularly from May through October. A contractor bringing a loaded roofing truck onto the ferry must plan weeks in advance, and a single weather cancellation can derail an entire project timeline.

Material staging challenges: Block Island has no roofing supply yard. Materials must be purchased on the mainland, loaded onto trucks, ferried across, unloaded, and stored on-island until the job begins. Storage space is at a premium, especially in summer when seasonal businesses occupy most available commercial space. Some contractors rent temporary storage containers positioned near job sites, adding $500-$1,500 per month to project costs. Materials left exposed to the island's salt air and weather deteriorate faster than on the mainland, making pre-staging a careful timing exercise.

Ferry costs for roofing projects: A round-trip truck ferry reservation costs approximately $150-$250 depending on vehicle size, plus additional per-person fares for crew members ($20-$30 round trip each). A typical roofing project requires 2-4 ferry crossings: one or two for material delivery, one for crew and equipment, and one for waste removal (Block Island has limited construction waste disposal capacity). Total ferry-related costs add $800-$2,500 to a standard roofing job. For larger projects requiring multiple material loads, ferry costs can exceed $4,000.

Crew accommodations: Mainland contractors working on Block Island must house their crews on the island. During the shoulder season (April-May and September-November), rental accommodations are more available and affordable, typically $150-$300 per night for a multi-bedroom rental. During peak season (June-August), accommodations can cost $400-$800 per night or simply be unavailable. A 5-day roofing project requiring a 3-4 person crew during summer can add $2,000-$4,000 in accommodation costs alone. This is a primary reason why contractors strongly recommend scheduling Block Island roofing work during shoulder seasons.

Waste removal: Block Island's small transfer station has limited capacity for construction debris. Old roofing material (asphalt shingles, underlayment, nails) must be properly disposed of, and the island's disposal fees are higher than mainland rates. Some contractors ferry waste back to the mainland for disposal, adding another ferry crossing and mainland dump fees. Budget $500-$1,500 for waste removal on a Block Island roofing project, compared to $200-$600 on the mainland.

Block Island: Extreme Wind and Weather Exposure

Block Island experiences the most extreme wind conditions of any inhabited location in Rhode Island. Sitting 12 miles offshore with no windbreak from any direction, the island is exposed to the full force of Atlantic storms, nor'easters, and hurricanes. The ASCE 7-16 wind speed map places Block Island in the 130 mph ultimate design wind speed zone, the highest in the state. But the actual sustained winds during major storms frequently exceed this design threshold, as evidenced by gusts over 100 mph recorded during Hurricane Bob in 1991 and sustained tropical-storm-force winds during Superstorm Sandy in 2012.

360-degree exposure: Unlike mainland coastal properties that typically face prevailing winds from one or two directions, Block Island homes receive punishing winds from every compass point depending on storm track and season. Northeast winds drive the powerful nor'easters that pound the island from October through April. Southeast and south winds accompany hurricanes and tropical systems. Southwest winds are the dominant summer wind. Northwest winds follow cold fronts. This omnidirectional exposure means every face of a Block Island roof is a windward face at some point during the year, and the typical mainland practice of prioritizing wind protection on the weather side is irrelevant. Every edge, every seam, and every fastener must be rated for maximum wind exposure.

Salt air from every direction: Block Island is completely surrounded by saltwater, and the prevailing onshore winds ensure that salt-laden air reaches every surface constantly. The salt corrosion rate on Block Island is among the highest in the northeastern United States -- metal components corrode 2-3 times faster than even mainland coastal Rhode Island communities like Narragansett or Westerly. Only marine-grade aluminum, 316 stainless steel, and copper are appropriate for any metal roofing component on Block Island. Standard galvanized steel, even hot-dipped, can show visible corrosion within 3-5 years.

Material recommendations for Block Island:

• Asphalt shingles: Class H (130 mph) minimum with 6-nail installation pattern. GAF Timberline HDZ, CertainTeed Landmark Pro, or Owens Corning Duration Storm. Full-deck self-adhering underlayment required for manufacturer high-wind warranty. All flashings must be aluminum or stainless steel.
• Standing seam metal: Aluminum panels with concealed clips rated for 150+ mph. This is the preferred choice for Block Island due to superior wind resistance and complete salt immunity. Colors should be factory-finished with PVDF (Kynar) coating for maximum UV and salt resistance.
• Natural slate: Appropriate for Block Island's historic structures, but the extreme wind requires copper or stainless steel fasteners and enhanced headlap. Weight is a concern for older structures. Cost: $25,000-$50,000+ for a typical island home.
• Cedar shingles: Historically common on Block Island, cedar shingles require stainless steel fasteners in the island environment. The HDC may require cedar for homes in the historic district. Cedar weathers to silver-gray within 1-2 years on the island due to intense UV and salt exposure.

Block Island: HDC Restrictions and CRMC Regulations

Block Island (New Shoreham) has two overlapping regulatory bodies that affect roofing projects: the Town of New Shoreham Historic District Commission (HDC) and the Rhode Island Coastal Resources Management Council (CRMC). Understanding both is essential before beginning any roofing project on the island.

New Shoreham Historic District Commission: The HDC's jurisdiction covers the designated historic district, which includes much of the Old Harbor commercial area and surrounding residential streets, as well as portions of New Harbor. Properties within the district that were built before 1950 are subject to HDC review for any exterior alteration, including roof replacement. The HDC requires a Certificate of Appropriateness before a building permit will be issued for roof work on regulated properties.

HDC-approved materials for Block Island:

• Generally approved: Natural slate (in colors matching the historic palette), cedar shingles (natural weathering, no stain), standing seam metal in traditional colors (dark gray, black, copper, weathered bronze), and high-quality architectural shingles in neutral earth tones (case-by-case basis).
• Requires individual review: Synthetic slate, composite shingles, and metal shingle systems. The HDC evaluates these on appearance from the street level and may require physical samples.
• Generally not approved: Corrugated metal panels, brightly colored metal roofing, exposed-fastener metal panels, three-tab shingles, rubber membrane visible from public way, and any reflective or high-gloss finish.

CRMC regulations on Block Island: The CRMC has authority over all of Block Island through both the standard Rhode Island CRMC program and the specific New Shoreham Coastal Resources Management Plan. Given that virtually every property on Block Island is within 200 feet of a coastal feature (shoreline, bluffs, salt ponds, or coastal wetlands), CRMC jurisdiction is essentially island-wide. Routine re-roofing with like-kind materials typically does not require a CRMC assent. However, the following roofing-related activities may trigger CRMC review:

• Structural changes to the roof framing (adding dormers, changing pitch, or increasing height)
• Converting from a lightweight material to a significantly heavier one (e.g., shingles to slate) that requires structural reinforcement
• Any work on properties in FEMA V-zones or coastal A-zones that could trigger the Substantial Improvement rule
• Roofing work that involves alteration of coastal features (bluff grading for equipment access, vegetation removal in buffer zones)

Application timeline: Factor in 2-4 weeks for HDC review and an additional 30-60 days if CRMC assent is required. Block Island homeowners should begin the permitting process 3-4 months before their desired construction start date. Working with a contractor experienced in New Shoreham regulations can streamline the process considerably.

Aquidneck Island: Newport, Middletown, and Portsmouth

Aquidneck Island is the largest island in Narragansett Bay and home to three municipalities: Newport (the southern tip, population ~25,000), Middletown (the central section, ~16,000), and Portsmouth (the northern portion, ~17,000). Unlike Block Island, Aquidneck Island is connected to the mainland by two bridges, making material delivery and contractor access far more straightforward. However, the island still faces extreme coastal exposure that sets it apart from mainland Rhode Island communities.

Coastal exposure by area: Aquidneck Island's roofing requirements vary significantly by location:

Newport's mansions and estates: The Gilded Age mansions along Bellevue Avenue and Ocean Drive represent some of the most complex and expensive roofing projects in New England. These structures feature massive slate roofs, ornate copper work, clay tile accents, and complex multi-faceted roof geometries that can span 5,000-15,000+ square feet. Roofing a Newport mansion can cost $100,000-$500,000+ and requires contractors who specialize in historic restoration and are experienced with traditional materials at this scale. Even homes that are not mansions in the Newport historic districts often have 150-200 year old slate roofs that need expert assessment.

Island Roofing Cost Comparison (2026)

The cost premium for island roofing varies dramatically between Block Island and Aquidneck Island, and both are above mainland Rhode Island rates. Here is a detailed comparison for a typical 1,500-square-foot roof replacement:

Where the Block Island premium goes:

• Ferry transport: $800–$4,000 (multiple crossings for materials, crew, and waste)
• Crew accommodations: $1,000–$4,000 (depending on season and project duration)
• Material storage: $500–$1,500 (temporary container rental)
• Waste removal: $500–$1,500 (higher island disposal fees or ferry back to mainland)
• Weather delays: $500–$2,000 (budget for 1-3 extra days due to weather)
• Scheduling premium: $500–$1,000 (limited contractor availability drives up labor rates)

Where the Aquidneck Island premium goes: The Aquidneck premium is more modest because bridge access eliminates ferry costs and allows contractors to commute daily from the mainland. The premium primarily comes from higher material specifications (marine-grade components required for coastal exposure), higher labor rates in the Newport market, additional permitting costs in historic districts, and the general cost-of-living premium in the Newport area. Pell Bridge tolls ($4 per crossing) add a nominal cost for mainland contractors commuting in.

Scheduling Island Roofing: When to Book and How Far Ahead

Timing is critical for island roofing projects, especially on Block Island where every aspect of the project is weather-dependent and logistically constrained. The scheduling requirements differ significantly between the two islands.

Block Island scheduling timeline:

• 3-6 months before: Contact contractors, get quotes, begin HDC/CRMC applications if required
• 2-3 months before: Sign contract, order materials, reserve ferry slots for delivery
• 1 month before: Confirm material delivery dates, arrange on-island storage, book crew accommodations
• 1-2 weeks before: Pre-stage materials on island, confirm weather forecast, finalize crew travel

Best months for Block Island roofing: Late April through early June (before peak tourist season) and September through mid-November (after summer crowds depart but before winter nor'easters begin in earnest). May and September are generally considered the optimal months, offering reasonable weather, available accommodations, and less ferry congestion.

Aquidneck Island scheduling timeline: With bridge access, Aquidneck Island projects can be scheduled on a more typical timeline of 4-8 weeks from contract signing to project start. However, projects in Newport's historic districts require 2-4 additional weeks for HDC Certificate of Appropriateness review. During the summer tourist season, Newport restricts some construction activities in the downtown and waterfront areas, which can affect scheduling. The best months for Aquidneck Island roofing are April through June and September through November.

Emergency repairs: Emergency roof repairs on Block Island after a storm present unique challenges. If ferry service is disrupted (common during the same storms that cause roof damage), mainland contractors cannot reach the island until service resumes. The few on-island contractors are typically overwhelmed with emergency calls from multiple properties. Homeowners should establish a relationship with an on-island contractor or handyman who can provide temporary tarping and stabilization while waiting for a full repair crew to arrive from the mainland.

Insurance Considerations for Island Properties

Insuring island properties in Rhode Island is more expensive and complex than mainland coverage. Both Block Island and the coastal portions of Aquidneck Island are in high-risk wind zones, and many properties fall within FEMA Special Flood Hazard Areas. These factors directly affect roofing decisions and project planning.

Wind/hurricane deductibles: Island properties typically carry the highest wind deductibles in Rhode Island, often 5% of dwelling coverage. For a Block Island home insured at $500,000 dwelling coverage, that is a $25,000 out-of-pocket deductible before insurance pays for wind damage. This makes investing in wind-resistant roofing materials and proper installation critical -- you are essentially self-insuring the first $25,000 of wind damage.

Material-based insurance discounts: Upgrading to wind-resistant roofing can earn significant premium reductions that help offset the higher material costs. Impact-resistant shingles (UL 2218 Class 4) may earn 5-15% discounts. Standing seam metal roofing may qualify for 5-20% discounts. Documented hurricane clips earn 5-15% reductions. Over a 25-year roof lifespan, these discounts can save $5,000-$15,000 in cumulative premiums, partially offsetting the island cost premium for higher-quality materials.

Flood insurance: Many Block Island and coastal Aquidneck Island properties are in FEMA V-zones or coastal A-zones requiring flood insurance. Flood premiums under FEMA's Risk Rating 2.0 can exceed $5,000-$10,000 annually for oceanfront island properties. Homeowners should be aware of the Substantial Improvement rule (50% threshold) before beginning roofing work, as triggering this rule in a V-zone can require elevating the structure at enormous cost. See our Coastal Roofing Rhode Island Guide for detailed FEMA flood zone information.

Choosing a Contractor for Island Roofing

Selecting the right contractor for an island roofing project requires evaluating capabilities beyond standard roofing competence. The logistical challenges of island work mean that experience and planning ability matter as much as roofing skill.

For Block Island projects, look for:

• Documented experience with Block Island projects (ask for specific references on the island)
• Established logistics for ferry scheduling, material staging, and crew accommodations
• Understanding of New Shoreham HDC and CRMC requirements
• Willingness to provide a fixed-price contract that accounts for weather delays and logistics
• Rhode Island Contractors Registration Board registration and adequate insurance
• Manufacturer certification for high-wind installation (GAF Master Elite, CertainTeed SELECT, etc.)

For Aquidneck Island projects, look for:

• Experience with Newport HDC requirements if your property is in a historic district
• Expertise with traditional materials (slate, copper, cedar) for historic properties
• Knowledge of coastal building codes and ASCE 7-16 wind requirements
• Portfolio of completed coastal projects on Aquidneck Island or similar exposures
• Marine-grade material specification as standard practice for island jobs

Red flags for island contractors: Be cautious of any contractor who quotes island work at mainland prices without accounting for logistics costs -- they will either cut corners on materials or hit you with change orders mid-project. Similarly, avoid contractors who have never worked on Block Island but claim the logistics are "no big deal." The ferry scheduling, storage, and weather challenges on Block Island have derailed many first-time contractors' projects, leading to costly delays and frustrated homeowners.

Wind Zone Requirements for RI Island Properties

Both Block Island and Aquidneck Island fall within Rhode Island's highest wind speed zones. The specific requirements are governed by ASCE 7-16 as adopted by the Rhode Island State Building Code. Understanding these requirements is essential for selecting the right materials and ensuring your roofing project passes inspection.

Block Island wind requirements: All of Block Island is in the 130 mph ultimate design wind speed zone. The island is also classified as Exposure Category D (open water/shoreline) on all sides, which further increases the calculated wind pressures on roofing assemblies. For practical purposes, this means every Block Island roof should be designed and installed as if it were on the most exposed oceanfront lot on the mainland. There is no "sheltered" location on Block Island.

Specific code requirements for 130 mph zones:

• Asphalt shingles must be ASTM D7158 Class H (130 mph) or higher
• Shingles must be installed with enhanced nailing: 6 nails per shingle minimum
• Starter strips must be self-sealing and rated for the applicable wind speed
• Underlayment must be self-adhering (peel-and-stick) on the full roof deck for high-wind warranty
• Drip edge must be installed at eaves and rakes per manufacturer specifications
• Roof-to-wall connections must resist calculated uplift forces (hurricane clips/straps required)
• Ridge caps must be installed with the manufacturer's high-wind method
