A rundown on roofing projects

No two home renovation projects are the same. Some projects are highly detailed undertakings that take months if not years from start to finish, while others can be tackled by skilled doit- yourselfers over the course of a single weekend. Though each project is different, categorizing renovations as needs or wants can help homeowners determine when the time is right to go forward.

Roof replacement projects typically fall into the “need” category. A decaying roof can jeopardize the safety and security of a home and lead to additional issues, like water damage. It’s unwise to delay roof replacement projects when signs of a decaying roof start to appear. Homeowners who are starting to see such indicators can look to this rundown of roof replacement projects as they begin the process of replacing their roof.

Cost

Roof replacement costs vary considerably depending on a host of variables. Materials, location and the cost of labor, dimensions of the roof, and even choice of contractor all affect the cost of the project. The home renovation experts at Angi indicate the average roof replacement project costs $9,500. Asphalt is among the more affordable roofing materials, costing an average of $1 to $1.20 per square foot, according to Nerdwallet. Slate roofs will be more expensive, costing anywhere from $10 to $30 per square foot.

Life expectancy

Homeowners may blanch at the cost of a roof replacement project, particularly if they choose a more expensive material. However, it’s important to keep life expectancy in mind when receiving roof estimates. Many homeowners never replace a roof twice, making this a potentially costly but ultimately onetime expense. Though slate roofs are expensive, homeowners may find it reassuring that estimates from various roofing resources indicate slate roofs come with a life expectancy ranging from 50 to 200 years. By contrast, Nerdwallet estimates an asphalt roof lasts around 10 to 20 years, while others suggest such roofs can last as long as 30 years.

Materials

Choice of materials is arguably the most significant decision homeowners will make when replacing a roof. The experts at This Old House report that materials typically account for 55 to 65 percent of the overall cost of a roof replacement project. Decisions regarding roof materials will be affected by budget, local climate (certain materials are better suited to particular climates than others), aesthetic appeal, and required maintenance. It’s also important that homeowners consider the material warranty of each roofing product. Some materials offer longer warranties than others, which can provide a measure of security to homeowners investing so much in the project.

A roof replacement project is not a renovation that can be delayed when signs the roof is fading start to appear. Homeowners are urged to consider a wide range of variables before committing to a project.
