FAQ

The average cost of a new roof in Pennsylvania ranges according to the size of the roof, the materials, the roof design, location and choice of roofing contractor amongst other relevant factors. It’s beneficial to have an accurate idea of the average cost of roof replacement in your area, but it’s important to understand that every project is different. 

According to data compiled by the US Census Bureau:

• The national average roof size is 1,700 square-foot or 17 SQ
• The most common type of residential roofing material is asphalt shingles
• Pennsylvania homeowners can expect to pay between $6.00 - $8.50 per square-foot of shingle roofing

Based on these numbers, a Pennsylvania homeowner with an average sized roof of 1,700 square-foot is likely to pay between $10,000 and $14,000 to replace their shingle roof. This coincides with estimates from the US Department of Energy indicating that the average cost to replace a shingle roof is $10,000 but can range anywhere between $8,500 to $14,300.

Note that these numbers are average estimates for a standard PA roof replacement project. If your requirements are more complex, you have a large property, or you choose premium roofing materials, the cost may be significantly higher.

The table below summarizes current US Census Data for the cost of replacing shingle roofing in Pennsylvania.

Data from This Old House for 2025 suggests that the average cost in Pennsylvania is similar to average prices in California, Florida, Georgia, Illinois, Michigan, New York, North Carolina, Ohio, and Texas. It is important to note that average roof costs vary according to your location. Prices may be higher or lower than those in the table depending on where you live, whether in-state or out-of-state. 

Nationally speaking, according to The Journal of Light Construction’s 2024 Cost Vs Value Report the average cost to replace a 3,000 square-foot asphalt shingle roof in the US is $30,680. This suggests a national average cost for replacing shingle roofing to be roughly $1,000 per SQ (or 100 square-foot), which is higher than Pennsylvania’s average shingle roofing costs of $700-$800 per SQ. For standing seam metal roofing, the figure increases to $49,928 for a 3,000 square-foot roof, which equates to an average cost of just under $1,700 per SQ.

Roof replacement and repairs represent a significant investment for home and business owners across the US. Before you spend money on your home or business premises, it’s essential to understand the costs involved. There are several key factors that influence roof replacement costs, which means the fee can range from less than $10,000 to more than $35,000. Understanding how pricing works and the elements involved in calculating costs will help you identify the best value quotes, budget for roof repairs or a new roof and choose suitable materials for your home.

If the numbers cited here are higher than expected it’s because the cost of roofing materials have increased significantly since 2020. Sources suggest that prices rose by up to 45% between the start of the Covid pandemic and August 2023. In the last 18 months, there have been further increases, with the latest hike expected to impact costs by around 6% - 8% following January 2025. As vendors are still updating catalogs, the true increase in cost is not yet known. We’re expecting to see the full impact of this latest cost increase on roofing materials by March 2025.

The cost of a new roof in Pennsylvania ranges significantly. The range is substantial because it reflects a multitude of factors that impact costs. Key factors to consider include:

Roof size is measured based on its surface area, which includes all sections of the roof, accounting for its shape and pitch (slope). Roofers typically measure the roof in square-feet but discuss it in terms of roofing squares (SQ), a standard unit in the industry.

Roofing Square:

• One roofing square (SQ) equals 100 square feet (sqft) of roof area.

• For example, a 2,000-square-foot roof is referred to as 20 roofing squares.

Measurements:

• Roofers often measure the length and width of each roof section and multiply these dimensions to calculate the total square footage.

• They also account for overhangs, dormers, and other architectural features.

Pitch Factor:

• The roof’s slope affects the actual surface area. Steeper roofs have more surface area than flat ones of the same footprint.

• Roofers use a pitch factor (based on the roof’s angle) to adjust measurements and ensure accurate material estimates. 

The size of the roof is a major factor in determining the cost of a new roof in Pennsylvania. Generally, as size increases the total cost to replace the roof increases proportionately. It’s important to note, however, size isn’t the only consideration. Comparing the cost of replacing a larger roof to a smaller one doesn’t always mean the larger roof will be more expensive. Other key factors, such as the quality and durability of materials and the complexity of the project, also play a significant role in determining the overall cost.

On the other hand, as the size of a roofing project increases, the cost per roofing square (SQ) for materials and labor often decreases, similar to the concept of buying in bulk. This is because bigger roofs enable the crew to work more continuously, reducing the time spent on setup, cleanup, and transitions between jobsites. Essentially, overhead costs, like transportation and equipment setup, are distributed across more squares, lowering the per-square labor expense. Moreover, some costs, like the rental of a dumpster container, remain the same regardless of roof size (to an extent). For example, the cost to dispose of old roofing materials is often similar for a 10-square roof and a 20-square roof, which makes the per-square disposal cost lower on larger projects.

In summary, roof size and total replacement cost are positively correlated—larger roofs typically result in higher overall replacement costs. However, there is often an inverse correlation between roof size and the average cost per square (SQ). In practical terms, this means that if your shingle roof is larger than your neighbor’s, you’ll likely pay more in total for your replacement, but your cost per square may be lower than what your neighbor would pay per square for their smaller roof.

Measuring your roof’s square footage and researching the roof replacement costs of nearby neighbors can provide valuable insights into the overall expense. 

Complexity is a key factor influencing the cost of a new roof in Pennsylvania, encompassing both the roof design and job site conditions. 

The more intricate and detailed the roof design, the higher the cost. Complex installations often require specialized skills, increasing labor costs, and may take longer to complete, further adding to the total expense. Additionally, certain structural complexities can raise material requirements, increasing material costs. In some cases, premium materials may be recommended to address specific challenges, further impacting the quote. For example, skylights and chimneys can significantly impact the cost of a roof replacement. These features require extra labor to integrate seamlessly into the new roofing system and demand additional materials to ensure proper sealing and functionality.

One major roof complexity that directly affects replacement costs is roof pitch, or the steepness of the roof’s slope. Roof pitch is typically expressed as a ratio, such as 6:12, meaning the roof rises 6 inches for every 12 inches of horizontal run. Steeper roofs are generally more expensive to replace due to the added challenges they present.

As the pitch increases:

• The surface area of the roof becomes larger, requiring more materials.

• Labor becomes more demanding and hazardous, as steeper slopes are more difficult to work on safely.

For very steep roofs, crews often need to install special jacks and planks, which act as safety platforms, enabling workers to move about the roof without slipping. These additional safety measures not only extend the time required to complete the job but also increase labor costs.

A roof hip is the external angle or ridge formed where two sloping roof planes meet. Unlike valleys, which are internal intersections, hips are found on the outer edges of a roof. They typically run diagonally from the corners of the roof to the ridge at the top, forming a “sloped edge”.

Roofs with more hips tend to have higher replacement costs due to the increased complexity they bring to a project. The design of a hip roof requires additional materials, such as ridge caps, and the way hips divide the roof into multiple sections creates more waste material. This happens because the cuts needed for fitting materials along the hips often result in leftover pieces that cannot be reused elsewhere.

The added labor involved in properly cutting and fitting materials along the hips also contributes to the cost. These areas demand precision and extra time to ensure a watertight seal, particularly as hips are critical points for potential leaks. Moreover, the intersecting roof planes in a hip design often require structural reinforcements, which further adds to the material and labor costs.



The slopes and angles of a hip roof can also make the installation process more challenging and time-consuming, especially on steeper roofs, increasing both the labor demand and safety considerations. Taken together, these factors—higher material usage, increased waste, added labor demands, and structural complexities—all contribute to the higher overall cost of replacing a roof with more hips.

Job site conditions further impact costs. For example, if your building is surrounded by adjacent structures that limit rooftop access, or if the nearest location for a dumpster is 100 yards away through a narrow alley, these challenges add to the labor demands. Extra time and effort required to navigate such obstacles drive up labor costs, making job site complexities an essential consideration in pricing.

By understanding how roof and site complexities influence costs, homeowners can better anticipate pricing variations and appreciate the skill and effort required for complex roof replacements.

The type of roofing material you choose for your new roof will have a big impact on the price you pay. Some materials are more expensive than others and some are more difficult to install, which also increases costs. It’s wise to weigh up the pros and cons of different roofing materials before you decide which option to choose.

Materials with a higher initial outlay may be less appealing if you’re on a tighter budget, but there are often opportunities to save money or add value in the long term. It’s helpful to calculate short and long-term costs and potential savings to help you decide which material will work best for your home. If you plan to stay at the property for many years, for example, you may want to invest in the most durable and aesthetically pleasing materials, which cost more. If low costs are a priority, it makes sense to opt for the least expensive materials. 

The table below highlights different roofing materials and their expected cost per SQ in Pennsylvania for 2025. Note that steep-slope roofing materials are grouped toward the top while low-slope (or "flat") roofing materials are grouped on the lower half.

Roof decking, the structural layer beneath your roofing materials, plays a crucial role in the overall cost of a roof replacement. It provides the foundation for shingles, metal panels, or other materials, and its condition directly impacts the durability and longevity of your roof.

If your existing roof decking is in good condition, the replacement cost may remain straightforward, as the new roofing can be installed without significant preparation. However, damaged, deteriorated, or spaced decking must be repaired or replaced to ensure the structural integrity of the roof. This additional work can significantly increase labor and material costs.

The type of decking material also influences costs. CDX Plywood and OSB (oriented strand board) are the most common and cost-effective options, but specialty materials, like tongue-and-groove planks, or thicker decking required for certain roofing systems can raise expenses. Additionally, code upgrades or reinforcement may be needed for homes in areas with specific wind, snow, or fire-resistance requirements.

Addressing roof decking issues is non-negotiable during a replacement project. A solid, properly installed deck ensures your roof performs as intended and avoids costly problems down the road. Investing in quality decking during a roof replacement is essential for long-term value and peace of mind.

Pennsylvania is a state that boasts a diverse range of properties located within a broad spectrum of sites, ranging from cosmopolitan cities and green suburbs to remote rural communities. The price of replacing or repairing your roof will vary, according to where you live in Pennsylvania. If you live in the heart of a bustling, modern city like Philadelphia, for example, you may find that labor costs are significantly higher than in rural areas due to the demand for skilled roofers.

In some Pennsylvania cities, performing work as a contractor requires obtaining a city-specific contractor license, which can add to roofing costs. For instance, in Scranton, contractors must secure a Scranton City Contractor License by paying fees, submitting documentation, providing references, and passing an exam annually.

Your location can also significantly influence the cost of a new roof, particularly if your home is in a  historical district.  Homes with “historical building” designation must comply with strict guidelines established by either a Homeowner’s Association (HOA) or the municipality’s historical district office. These rules often limit changes to a building’s exterior components which includes the type of roofing materials. As an example, if your historical home has a cedar shake roof that needs replacement, regulations will likely require you to use the same cedar shake material, one of the most expensive roofing options. In such cases, less costly alternatives like asphalt shingles would not be permitted, potentially leading to higher expenses for your roof replacement. Compliance with these preservation standards ensures the historical character of the property is maintained but can significantly impact the overall project cost.

Other location-based factors such as property accessibility, local building codes and the availability of specific roofing materials can also affect the cost to replace your roof. Learning more about the importance of your location within Pennsylvania can help you estimate roof replacement costs more accurately based on where you live. 

The cost of a new roof in Pennsylvania depends heavily on labor costs and the contractor you choose to carry out the work on your home. Experienced roofers may charge more than novices and in most cases, you pay a premium for first-class craftsmanship. To find the best value quote, it’s beneficial to contact multiple contractors to get quotes for your new roof. This will enable you to compare prices and services and get a better idea of what different contractors offer. 

It’s wise to prioritize value for money over costs when comparing quotes from roofing companies. If you can afford to pay for the finest materials and the most experienced contractors, for example, there’s a higher chance of achieving the best quality finish, which will save you money in the long term. This is particularly beneficial if you’re keen to add value to your Pennsylvania home or you plan to stay at the same property for several years. 

Deciding whether to include a roof warranty in your replacement project can significantly impact the overall cost. Roof warranties come in two main types: manufacturer warranties, which cover defects in the roofing materials, and workmanship guarantees, which cover installation errors.

Opting for a warranty often increases the upfront cost of a new roof but provides long-term value and peace of mind. For example, premium manufacturer warranties, such as those offering lifetime coverage, may require using certified contractors and specific materials, which can elevate costs. However, these warranties often include additional benefits like enhanced material performance and coverage for labor in case of defects.

At Rob’s General Contracting, we take pride in being GAF Certified Residential Roofing Contractors and prodigious advocates of the GAF Lifetime Roofing System. When homeowners need a shingle roof replacement, we typically provide 2–3 estimates to ensure they have options. One of these estimates always features the GAF Lifetime Roofing System, which includes an enhanced lifetime warranty for comprehensive peace of mind. Another estimate presents a more basic option without a uniform roofing system or warranty.

While the GAF Lifetime Roofing System estimate is usually higher in cost, we strongly recommend it for its superior quality, durability, and long-term value. Most of our customers recognize the exceptional benefits of investing in this system and choose it to protect their homes.

Workmanship guarantees can also influence costs, as contractors who offer extended or guaranteed workmanship often have higher pricing to reflect their expertise and commitment to quality. These warranties protect against issues like improper installation, which can save you from costly repairs down the road.

With over 30+ years of experience as a family-owned roofing company, we confidently stand behind our work - which is why we offer a "Rob's GC 10-Year Workmanship Guarantee" on ALL roof replacement projects at no extra cost. 

If you're on a tight budget, choosing not to include a warranty may reduce your initial costs when getting a new roof for your home. That being said, doing so places you at a greater risk of paying more costs later. Without a warranty, you’ll bear the full cost of any future repairs or replacements caused by material failure or installation errors.

Ultimately, investing in a roof warranty can raise your upfront costs but offers  valuable protection, ensuring your roof’s durability and minimizing unexpected expenses in the long term. It’s essential to weigh the added cost against the potential risks and benefits when planning your roofing project.

There is no universal answer to the question, ‘Which is the best roofing material?’ as every property is different and homeowners have varied requirements and preferences. To help you decide which material is best for your home, it’s beneficial to explore all the options, compare the pros and cons, get quotes and seek expert advice. Experienced, reputable roofing contractors will be able to offer tailored advice and recommendations based on your roof, the type of repairs or installation required, your budget, and your priorities. 

When you compare roofing materials, consider all the factors, including short and long-term costs, durability, aesthetics and ease of installation. You can then consider the advantages and disadvantages and relate them back to your property and your preferences. Some homeowners, for example, may want to choose the least expensive materials because they plan to move or they’re on a tight budget. Others may want to prioritize longevity or aesthetics, which may mean spending more on materials. In other cases, experts may recommend specific materials due to the nature, size or complexity of the replacement. 

If you have any questions about roofing materials, it’s an excellent idea to seek professional advice. This will give you clarity and help you narrow down the options. 

Every homeowner wants to get the best possible deal on home repairs. To help you save money on your new roof, here are some top tips:

1) Take action early: It’s often much more cost-effective to tackle minor repairs than to leave your roof to deteriorate.

2) Consider scheduling work late-season: Labor costs peak during the warmer months when the demand for roofing contractors increases. If you can, schedule work at the end of fall/start of winter to reduce costs. 

3) Investigate financing options: In some cases, customers can benefit from financing options, which help to spread the cost of a new roof, making it more affordable. Ask your contractor about finance plans before you commit. It’s important to make sure you can afford the repayment costs before you sign any agreements. 

4) Check your insurance: Before you invest money in roof replacement, check your insurance. You may be covered if your home was damaged as a result of a storm, for example. 

5) Compare several quotes: It’s always a good idea to get several quotes from reputable, highly rated contractors.

How much does a new roof cost in Pennsylvania?

The total cost of roof replacement will depend on several factors, including the size and shape of your roof, the complexity of the roof design, the materials you choose, labor costs, and your location within the state. Asphalt Shingles are the most common type of residential roofing material and the average cost to replace a shingle roof in Pennsylvania is estimated to be around $10,000.

Which factors affect the cost of roof replacement in PA?

The main factors that affect the cost of roof replacement in Pennsylvania include the size of the roof, the cost and availability of the materials you use, the expertise and experience of your contractor, your location (prices tend to be higher in big cities) and the scope of the quote. 

Which roofing materials are best?

There are pros and cons to using every type of roofing material. Slate, metal and tiles are popular due to their durability and aesthetic appeal while asphalt shingles are an affordable choice. It’s beneficial to weigh up the pros and cons, compare prices and consider the requirements of your project before you decide. It’s also wise to seek professional advice from reputable roofing contractors to get tailored recommendations and quotes. 

How can I ensure the best results when replacing my roof?

The best way to guarantee impressive results when replacing your roof is to choose an experienced, professional, reputable roofing contractor. Research roofing companies on social media, read verified reviews and ask people you know for recommendations. Always select companies or contractors that are licensed and insured and be sure to ask if they offer any roof warranties.

What is the most expensive roofing material? 

Slate is widely regarded as the most expensive roofing material. Natural slate tiles are crafted from stone, offering unmatched durability and a lifespan of over 100 years. Their luxurious appearance and exceptional longevity come at a high cost, with prices often exceeding $20 per square foot for materials alone, plus additional costs for specialized installation. That being said, it's more practical now to install imitation slate roofing - which is less expensive compared to real slate.

Other premium options like Terra Cotta Tiles, Cedar Shakes, and high-end metal roofing systems such as standing seam or stone coated steel can be just as costly.

What are the different types of asphalt shingles?
There are three main types of asphalt shingles, each offering distinct advantages:

1. 3-Tab Shingles: These are the most basic and affordable option, featuring a flat, uniform appearance with evenly spaced tabs. They’re lightweight and suitable for budget-conscious projects but have a shorter lifespan (typically 20–30 years) compared to other types.
2. Architectural (Dimensional) Shingles: These are thicker and more durable than 3-tab shingles, with a layered, dimensional appearance that mimics the look of wood or slate. They offer improved wind and weather resistance, lasting 30–50 years, and are the most popular choice for residential roofing.
3. Designer/Luxury Shingles: These are the highest-quality asphalt shingles, designed to replicate the appearance of premium materials like slate or cedar shakes. They’re heavier, more durable, and provide exceptional curb appeal and weather protection, though they come at a higher cost.

Each type of asphalt shingle offers different benefits, allowing homeowners to choose based on their budget, aesthetic preferences, and durability needs.

What are some examples of designer or luxury shingles?

When is the best time of year to get a new roof installed?

The best time to install a new roof is often in late fall. During this time, temperatures are cool but not freezing, which is ideal for roofing materials and adhesives to set properly. Additionally, late fall weather typically features fewer storms compared to earlier in the season, making conditions more predictable for roofing projects.

Roofing contractors may also have greater availability in late fall as the peak busy season of summer and early fall winds down. This can make it easier to schedule your project and may even result in more competitive pricing. While roofing can be done year-round, late fall often offers the perfect balance of favorable weather and contractor availability for a high-quality, efficient installation.

Should I consider lifespan when choosing a new roofing material for my home?
The lifespan of a roofing material is a key factor in determining the long-term value and durability of your investment. Choosing a roofing material with a longer lifespan means fewer replacements over the years, saving you money on future labor and materials.

A longer-lasting roof can also increase your home’s value and provide peace of mind, especially if you plan to stay in your home for many years or want to leave a reliable roof for the next owner. Additionally, durable materials like slate, metal, or tile often require less maintenance, further reducing costs over time.

While materials with shorter lifespans, like asphalt shingles, may have a lower upfront cost, they’ll likely need replacement sooner, potentially costing more in the long run. Considering the lifespan of a roofing material ensures you make a choice that balances your budget, future needs, and the overall durability of your home’s roof.

How long will it take to replace my roof?
In most cases, a day.

Can we put a new roof in during winter?
Yes, you can get a new roof installed during winter! While winter roofing presents some challenges, experienced contractors are equipped to handle cold-weather installations effectively. Asphalt shingles, for example, can still be installed, but care must be taken to ensure proper sealing, as adhesives may take longer to set in colder temperatures.

Winter roofing projects often come with benefits, such as greater contractor availability and potentially quicker scheduling, as it’s typically a less busy time of year for roofing companies. However, extreme conditions like heavy snow or ice may cause temporary delays.

If you need a roof replacement in winter, working with a skilled roofing contractor ensures a safe and successful installation despite the colder weather.
