Architectural Shingles
Architectural shingles, also known as dimensional or laminate shingles, are now the most common asphalt shingle used in roof replacements across New England. They are engineered with multiple layers of asphalt and granules to create a thicker, more dimensional product that casts a visible shadow line, mimicking the look of traditional wood shakes or natural slate.
What Are Architectural Shingles?
Modern architectural shingles are a significant advancement over the older three tab asphalt shingles. Unlike the flat, single-layered design of a three tab shingle, architectural products are made with two or more layers of asphalt material laminated together. This construction gives them a distinct, textured appearance that enhances the aesthetic of many homes, from a classic center chimney colonial to a Victorian.
The layered design provides more than just visual appeal. It contributes to a heavier, more robust shingle that offers better protection against the elements. Their weight and construction allow for significantly higher wind ratings, often resisting winds up to 130 miles per hour, which is crucial for exposed homes in coastal areas of Rhode Island and Massachusetts. These shingles typically carry a lifespan of 25 to 30 years, a notable improvement over the 15 to 20 year life of a three tab shingle.
The Installation Process for Dimensional Shingles
Replacing a roof with architectural shingles begins with a full tear off of the existing roofing materials down to the roof deck. This step is critical because it allows for a thorough inspection of the wood sheathing for any signs of damage or rot. Any compromised sections of plywood or old plank sheathing must be replaced or repaired to ensure a solid foundation for the new roof system.
Once the deck is sound, a critical layer of ice and water barrier is applied along the eaves, valleys, and around any penetrations like chimneys or skylights. This provides enhanced protection against water intrusion from ice dams and heavy rain. Next, a synthetic underlayment covers the remainder of the roof deck, offering a secondary layer of defense against moisture. Drip edge flashing is then installed along the eaves and rake edges, followed by a starter shingle course that ensures the first row of architectural shingles is properly secured and sealed.
The main field of architectural shingles is then installed, typically with four or six nails per shingle, placed precisely according to manufacturer specifications. Flashing around chimneys, skylights, and vents is replaced or properly integrated. The process concludes with the installation of ridge cap shingles, which are specifically designed to cover the peaks and hips of the roof, providing both protection and a finished appearance. For a typical 1,800 square foot residential roof, this entire process can take between 3 to 5 working days, depending on weather and roof complexity.
Comparing Architectural Shingle Costs and Lifespans
When considering a roof replacement, material choice plays a significant role in both initial cost and long term value. Three tab asphalt shingles, while less expensive at $4 to $5.5 per square foot installed, offer a shorter lifespan of 15 to 20 years. For most homeowners in Connecticut, Rhode Island, and Massachusetts, standard architectural asphalt shingles are now the default, offering a better balance of cost and performance.
Standard architectural shingles typically cost $5.25 to $7.5 per square foot installed and come with a 25 to 30 year life expectancy. This difference in price often translates to better durability, improved wind resistance, and a more visually appealing roof. The investment often pays off over time due to reduced maintenance and a longer service life. For a full tear off and replacement on an 1,800 square foot home, expect a project range of $11,000 to $24,000, with material choice being a key factor in that variance.
Premium Architectural Shingles and Alternative Roofing Materials
For those seeking even greater longevity and a more distinct aesthetic, premium architectural shingles are available. These heavier, often thicker shingles are designed to replicate natural wood or slate more closely and offer a life expectancy of 30 to 40 years. Installed costs for premium architectural shingles typically range from $7 to $9.5 per square foot.
Beyond asphalt, other roofing materials offer extended lifespans but at a higher investment. Standing seam metal roofing, for example, is priced at $14 to $20 per square foot installed and can last 50 to 70 years. Synthetic slate, at $18 to $26 per square foot installed, also offers a 50 to 70 year life. While these alternatives represent a much higher initial outlay, they are a suitable choice for homeowners planning to stay in their property for several decades or those with specific architectural demands. For flat and low slope sections of roofs, EPDM low slope roofing is a common solution, costing $7.5 to $11 per square foot installed with a 20 to 30 year life.
Understanding Shingle Wind Rating and Durability
A key performance advantage of architectural shingles is their wind resistance. Most architectural shingles are rated to withstand winds up to 110 or 130 miles per hour, significantly higher than the 60 to 70 mph ratings common for three tab shingles. This enhanced rating is a direct result of their heavier weight, layered construction, and stronger adhesive strips, which help bond them securely to the roof deck and to each other.
This improved wind rating is particularly important for homes throughout New England, which regularly experience severe weather, including nor'easters and hurricanes. A higher wind rating reduces the risk of shingle blow-off during storms, minimizing the need for emergency repairs and extending the overall life of the roof. The density and granule coverage of architectural shingles also offer greater resistance to hail damage and UV degradation, further contributing to their long term durability.
Architectural Shingles Across New England Housing Styles
Architectural shingles are a versatile choice that complements various housing styles found throughout Rhode Island, Massachusetts, and Connecticut. For classic center chimney colonials and Victorians, the dimensional shadow lines of these shingles correctly reflect the historical character of the home, unlike the flat appearance of three tab shingles which can look out of place.
On simpler postwar capes and ranches, architectural shingles provide an upgrade in appearance and durability. Their robust nature also makes them well suited for triple deckers, which often feature steep pitches and are exposed to varied urban conditions. Even shingled coastal cottages benefit from architectural shingles, as their higher wind ratings offer enhanced protection against the strong winds and salt air prevalent in maritime environments. Many older homes, particularly those built before the 1970s, often have plank or board sheathing, which requires careful fastening of new shingles to ensure long term adherence and structural integrity.
Recognizing Poor Architectural Shingle Installation
Even the highest quality architectural shingles will fail prematurely if not installed correctly. One common issue is improper nailing, either too high, too low, or at an angle. This can lead to shingles not sealing properly, making them susceptible to wind uplift and blow-off, even in moderate winds well below their rated capacity. Insufficient fastening can also cause shingles to buckle or curl over time.
Another critical failure point is incorrect flashing around chimneys, skylights, and valleys. If flashing is not installed with proper overlaps and sealed correctly, water will find its way into the home, leading to leaks, rot in the roof deck, and interior damage. Poor attic ventilation, which is often overlooked during roof replacement, can also cause problems. Inadequate airflow can lead to excessive heat buildup, prematurely aging the shingles from the underside and potentially voiding material warranties.
Key Elements to Look for in a Roofing Quote
A comprehensive roofing quote for architectural shingles should clearly itemize all aspects of the project. It should specify the number of existing roofing layers to be torn off, as this impacts labor and disposal costs. A line item for roof deck repair, often an allowance, is important for addressing unforeseen damage once old materials are removed. The type and coverage of ice and water barrier, as well as the synthetic underlayment, should be detailed.
The quote should also specify the brand and color of the architectural shingles, as well as the type of ridge vent or other ventilation strategy to be installed. Details regarding flashing materials, such as custom bent metal for valleys and chimneys versus relying solely on mastic, are important. Finally, look for clear terms on waste disposal, site cleanup, and any manufacturer or workmanship warranties. A thin quote that lacks these specifics can lead to unexpected costs and confusion during the project.
Common questions
Architectural shingles are constructed with multiple layers of asphalt and granules, creating a thicker, more dimensional product. This contrasts with three tab shingles, which have a single, flat layer. The layered design of architectural shingles provides better durability, significantly higher wind resistance, and a more aesthetically pleasing, textured look that resembles natural wood shakes.
Yes, architectural shingles have a higher installed cost per square foot compared to three tab shingles. Standard architectural shingles typically cost $5.25 to $7.5 per square foot installed, while three tab shingles range from $4 to $5.5 per square foot installed. However, architectural shingles offer a longer lifespan, often 25 to 30 years compared to 15 to 20 years for three tab, which can represent a better long term value.
Architectural shingles are designed to perform well in New England's varied climate. They typically have a lifespan of 25 to 30 years, with premium architectural options extending to 30 to 40 years. Their heavier construction and high wind ratings, often up to 130 miles per hour, help them withstand severe weather conditions common to Rhode Island, Massachusetts, and Connecticut, including heavy snow, ice, and strong winds.
While architectural shingles are an excellent choice for most homes, you might consider alternatives for specific situations. If you desire a roof with a lifespan exceeding 40 years, materials like standing seam metal or synthetic slate, which can last 50 to 70 years, are worth exploring. These options come at a higher cost but offer long term durability and unique aesthetic qualities suitable for certain architectural styles or long term investment strategies.
Several factors influence the total cost of an architectural shingle roof replacement. These include the size and complexity of your roof, such as its pitch, the number of valleys, dormers, or chimneys. The number of existing shingle layers to be torn off, the extent of any necessary roof deck repairs, and your choice between standard or premium architectural shingles also play a significant role. Accessibility for material delivery and debris removal can also affect labor costs.
