1.How To Calculate The Roof Area

There are two terms that roofers use to describe the area of the roof: a base roof area and the actual roof surface area. Our roof price calculator requires you to enter the base roof of your area and its angle. The base roof area is calculated by multiplying the base length of your home by its width. If the shape of your house is more complex, you would need to calculate the areas of the rectangular parts and sum them up. Knowing your roof area is needed to use our roofing cost calculator.

Another term is the actual roof area that takes your roof’s pitch into consideration. Here is the guide on how to calculate the pitch of your roof.

How To Calculate The Pitch

Roof pitch is the slope created by the rafters and is measured by rise and run.

  • 1. Rise (A): the distance from the top of a stud wall to the peak of the roof.
  • 2. Run (B): the distance from the outside edge of a perimeter stud wall to the center of the house; the run always remains constant at 12 inches.

Roof pitch is the slope created by the rafters and is measured by rise and run.

Pitch is the ratio of the rise of your roof to its run (Pitch = Rise/Run). You can also convert the degree of your roof angle to submit it to our roofing cost calculator by using the conversion table below.

Residential vs. Commercial Roofing: What is the difference?

There are three major differences between commercial and residential roofs that are going to be discussed further. Choosing the right material is important to get an accurate estimate using our roof price calculator.

1. Roof Design

The design is different for both residential and commercial buildings. Commercial roofs typically have a very low or entirely flat slope. This type of roofs is typically seen on warehouses, shops, restaurants, and factories and cover a much bigger area than a typical residential roof. A residential roof usually has a higher pitch and is smaller. Our roof price calculator does not actually consider your roof’s design so the estimate is not always accurate and final.

2. Roof Installation and Repair Requirements

Installation and repair requirements for commercial and residential properties vary. For example, a commercial roof usually takes longer to install while a residential roof can take just a few days. The skillset and the process are also different for both roofing types. Our roofing calculator does not include the cost of the workmanship.

Typically, the process for installing residential roofs involves nailing plywood to wooden rafters, creating the roof deck. Then, a protective underlayment is laid down, before installing shingles, shakes, or tile. A commercial roof is built using multiple layers, like insulation, decking, protective coating, and reflecting coating. You can see that the price of commercial roofing types is slightly higher in our roof replacement cost calculator.

Repairs on commercial roofs can become a major project because it might involve patching one section of the roof or making major repairs and reapplying large layers. Our roof price calculator will estimate the cost of your commercial roof repair. A simple leak can cost a lot of money. It is not the same with a residential roof: leaks often occur in isolated spots where it is easy to replace shingles that are loose or flashing that has corroided. The leak can usually be fixed in a few hours. Leaks can, of course, lead to major roofing problems if left unattended. However, it is rare for isolated leaks due to minor problems. You can also use our roof repair cost calculator to get the estimate for your repairs.

A Brief Overview of The Most Popular Roofing Materials

Residential Roofing

Our roof price calculator can give you an estimate for your residential roof replacement. However, for a detailed estimate, a roof calculator cost might not be that accurate because of the measurements mitakes. You should contact a roofing company for an inspection and a more accurate estimate. But picking the right material is important. There are three common types of residential roofing materials listed in our roof calculator.

Architectural Shingle

Asphalt roofing shingle is the most popular residential roofing material for our roofing cost calculator. Nowadays, modern asphalt shingles (also called architectural shingles) are an appealing choice because of their durability and availability: they can last up to 25 years. They provide effective protection against wind uplift and blow-off, and water penetration from hails and storms. In addition to their cost-effective nature and durability, asphalt shingles come in a wide variety of colors and shapes. Use our asphalt shingle roof cost calculator to get the estimate.

HD Architectural Shingle

Architectural laminated shingles are often described as “high-definition” because of their depth and contour. They consists of two or more basic shingles laminated or bonded together. That is the main difference between the HD architectural shingles and architectural shingles. They have a more wholesome and “natural” look.

Tile Roofing System

A tile roof is a roof made from clay, ceramic, concrete or slate tiles, while each tile is secured to the roof deck by nails. Tile is weather-resistant and is known for its durability and ability to withstand high winds, hail, fading, and even fire. Tile roofs are generally durable and can last up to 50 to 70 years. It is another good option for residential roofs but is a bit more expensive. Tile roofing systems fit well in the Southwest homes that borrow elements of Spanish architecture. They might not be suitable for climates with fluctuating weather because of their tendency to erode. Our roof calculator will calculate the cost of your tile roofing system installation.

Metal Roofing System

Metal roofs can last up to 70 years on both residential and commercial roofs as steel is very durable and corrosion- and fire-resistant, which makes them a good investment. They are also an energy-efficient solution because it reflects heat well. The advantages of this roofing material, however, make it a quite pricey solution. While there is lots of benefits, the installation process can be tricky, so it’s essential to hire a professional roofer who has experience in metal roofs installation. Use our metal roof cost calculator if you are looking for metal roof installation.

Commercial Roofing
