When considering a new roof or replacing an existing one, one of the first questions homeowners ask is how large the roof will be, especially when it comes to a 1700 square foot house. Understanding the size of your roof is crucial for planning a roofing project, budgeting for materials, and ensuring that you are hiring the right contractor for the job. With CJ Commercial Roofing NJ, we’ll explore how to estimate the roof size of a 1700 square foot house in New Jersey, taking into account different factors such as roof pitch, design, and the impact of local weather conditions.
Understanding Roof Measurements
Before diving into how to determine the size of a roof, it’s important to understand the different terms and measurements that come into play:
- Roof Square: A “roof square” refers to a unit of measurement used by roofing professionals. One roof square is equal to 100 square feet of roofing material. This is the standard unit of measurement for roofing projects.
- Roof Area: The roof area is the total surface area of your roof, which is typically measured in square feet. This is what determines how much roofing material you’ll need, from shingles to underlayment.
- Roof Pitch: The pitch of your roof, also known as the roof slope, affects the overall roof area. A roof with a steeper pitch will have a larger surface area than a roof with a low pitch, even if the footprint of the house remains the same.
Estimating the Size of a Roof on a 1700 Square Foot House
To calculate the approximate roof size for a 1700 square foot house in New Jersey, we need to factor in the design of the house, roof pitch, and any additional features like dormers or valleys. Here’s a general approach:
- Basic Calculation (Flat Roof):
For a simple, flat roof with no pitch, the roof size would be approximately the same as the footprint of the house. In this case, if the house is 1700 square feet, the roof would also be around 1700 square feet. - Standard Pitched Roof:
Most homes in New Jersey have pitched roofs to allow for water drainage and to withstand the heavy snowfall in the winter. For homes with a gable or hip roof, you typically need to account for the slope. The most common pitch for homes in New Jersey is a 4/12 pitch, which means the roof rises 4 inches for every 12 inches of horizontal distance. To estimate the roof size for a pitched roof, you need to factor in the roof pitch using a multiplier. For example, a 4/12 pitch will typically increase the surface area of the roof by about 1.1 times. So, for a 1700 square foot house with a 4/12 pitch, you would multiply the footprint by 1.1: 1700 square feet x 1.1 = 1870 square feet Therefore, a 1700 square foot house with a 4/12 pitch roof would have a roof area of approximately 1870 square feet. - Steeper Pitched Roof:
If your roof has a steeper pitch, such as a 6/12 or 8/12 pitch, the surface area increases even more. For a 6/12 pitch, the roof area will be about 1.2 times the house’s footprint: 1700 square feet x 1.2 = 2040 square feet For an 8/12 pitch: 1700 square feet x 1.3 = 2210 square feet The steeper the pitch, the larger the surface area of the roof, which also means more roofing material and a higher cost.
Local Considerations for Roof Size in New Jersey
New Jersey’s weather conditions play a significant role in the type of roof you might need. The state experiences hot, humid summers and cold, snowy winters, both of which can impact the design and materials used for your roof. Here are a few important factors to keep in mind:
- Snow Load:
In the winter months, New Jersey can experience significant snowfall, particularly in the northern and central regions. This means that your roof must be designed to handle the weight of snow accumulation. Homes in areas like Morris County, Passaic County, or Sussex County may require a steeper pitch to prevent snow buildup and reduce the risk of leaks or roof damage. Additionally, roofs in snow-prone areas may need to be reinforced, which could impact the overall roof size and material requirements. - Hurricane-Resistant Roofing:
Coastal areas of New Jersey, such as Monmouth County and Ocean County, are more susceptible to hurricanes and strong storms. If you live near the shore, you might want to consider a roof designed to withstand high winds. This could involve using durable materials like metal roofing or installing additional reinforcements, which may also increase the overall size of your roof. - Local Building Codes:
New Jersey has strict building codes that regulate roof design and materials. When planning your roof replacement or installation, it’s important to consult with local professionals to ensure that your roof complies with all local regulations, especially regarding snow load, wind resistance, and material choice. The roof pitch and design may need to be adjusted based on these codes.
Materials for Roofing in New Jersey
The choice of roofing material can significantly affect the roof size and overall cost of the project. The most common roofing materials used in New Jersey include:
- Asphalt Shingles:
Asphalt shingles are the most popular roofing material in New Jersey due to their affordability, ease of installation, and weather resistance. For a 1700 square foot house, you can expect to pay between $5,000 and $10,000 for an asphalt shingle roof, depending on the pitch and complexity of the roof. - Metal Roofing:
Metal roofs are becoming increasingly popular due to their longevity and resistance to extreme weather conditions. If you live in a coastal area or somewhere that experiences heavy snow or wind, a metal roof might be the best option. Metal roofing costs can range from $8,000 to $15,000 for a 1700 square foot house, depending on the type of metal used. - Wood Shingles or Shakes:
Wood shingles or shakes provide a unique aesthetic but require more maintenance than asphalt or metal roofs. These materials are less common in New Jersey due to the potential for mold and rot, especially in coastal areas. The cost of wood roofing can vary widely, from $7,000 to $12,000 for a 1700 square foot house.
