What Does It Cost to Replace a Roof?

Replacing a roof is one of the most important home improvement projects. Like any other major job, homeowners can’t rush headlong into it without determining the price. Otherwise, they may choose inadequate materials and exceed the budget.

Knowing the price of replacing a roof beforehand, therefore, is crucial. Here are the determining factors:

Roof size

The size of the roof is one of the most significant factors impacting the replacement price. The greater the surface area that needs to be covered, the higher the cost will be. The roofing contractor will need more materials, such as shingles, underlayment, and plywood.

Preparation

Before installing a new roof, the contractor will need to prepare the area. The amount of work necessary depends on the appearance of the roof, but it typically includes the following tasks:

  • Removing old materials

  • Examining the underlayment

  • Checking for warping, peeling, and water damage

  • Assessing the plywood, flashing, and seals

Extensive preparations will cost more, as the contractor will need to invest more time and effort.

Roofing materials

The price of roofing materials can vary dramatically. Families on a budget can opt for low-quality solutions that meet the minimum code requirements. However, installing subpar materials is ill-advised since they don’t last and often won’t stand up to extreme weather. The cheapest option is 3-tab asphalt shingles that usually go for $90-$100 per 100 square feet.

On the other hand, selecting high-quality materials helps ensure the roof lasts for decades. One of the best options is slate. Even though it costs upwards of $600 per 100 square feet, it can last for more than a century. Other durable solutions include metal and concrete.

Moreover, materials with special applications may increase expenditures. Roofers need to follow the manufacturer’s instructions closely to ensure accuracy, leading to a higher price.

Level of difficulty

The harder it is to replace a roof, the higher the cost to do so will be. Two variables dictate the difficulty factor: complexity and accessibility.

Complex roofs cost more because they require additional time, attention to detail, and materials to perform the installation correctly. They usually feature many extra components, such as skylights, solar panels, and multifaceted angles. All of these add time to the schedule, which translates into increased costs.

Likewise, inaccessible roofs that are multiple stories high are generally more expensive than single-story constructions. Contractors may not be able to reach them easily due to the slope of the roof or nearby structures. Accordingly, hauling materials onto the roof requires more time and concentration to prevent damage and accidents.

Make an informed decision

Delving deeper into all these factors will help you pick the right replacement roof. To find the ideal solution and receive an accurate figure, consult a seasoned roofing company.
