Unfortunately, roofs have a limited useful life. Typically, asphalt shingles need to be replaced every 20 years. Alternatively, metal and tile roofs generally are more durable and can last between 30 and 50 years. Undertaking a roof replacement is a significant project for any homeowner, and understanding the timeline involved can help set realistic expectations and help you plan for the project. This guide will delve into the factors that affect the timeframe for completing a roof replacement, helping you plan and minimize disruptions to your daily life.

Size and Configuration of the Roof

As you may imagine, it typically takes more time to replace a 2,000-square-foot roof than a 1,000-square-foot roof. Fixtures such as chimneys or skylights can also extend the timeline for replacing your roof, as they require careful attention to ensure proper sealing and integration with the new roofing materials.

Additionally, working on a steeper-pitch roof can take longer. Roofers may need additional safety measures such as harnesses, anchors, or scaffolding to navigate the steeper slope safely. The steep angle of the roof can also make it more challenging to move materials and equipment, further contributing to the project’s time requirement. A roofing professional can give you a good idea of how the size and configuration of your roof will impact the project’s duration.

A Full Tear-Off Typically Takes Longer

When considering a roof replacement, homeowners often have the choice between a full tear-off or adding a new layer of shingles over the existing roof. Opting for a tear-off involves removing all layers of the existing roofing material down to the roof deck. This process can take several days to complete, as it requires removing old materials and thoroughly inspecting the underlying structure for any damage or issues that need addressing before installing the new roof.

On the other hand, adding a new layer of shingles, also known as a re-roof or overlay, can be a quicker process. It typically takes only a day or two to lay down the new shingles over the existing ones. This option may seem more convenient and cost-effective initially, but it’s essential to consider the long-term implications. Most building codes allow for only two layers of shingles on a roof due to the added weight. If there is already one layer in place, adding another layer may not be an option, necessitating a tear-off.

The decision between a tear-off and adding a new layer depends on various factors, including the existing roof’s condition, local building codes, and budget considerations. While a tear-off may require more time and investment upfront, it offers the advantage of a fresh start, allowing for thorough inspection and potential repairs to the roof deck and underlying structure. This can result in a longer-lasting and more durable final product, providing greater peace of mind for homeowners in the long run.

The Scope of the Job Might Change

Typically, an inspection is done prior to starting a roof replacement project. However, this doesn’t mean that problems won’t arise after work begins. For instance, decking that wasn’t exposed before shingles were removed may show signs of water damage, such as rotting wood, that a roofer wouldn’t have been aware of before work began.

A reputable roofing company will not simply put new shingles on top of bad decking. Instead, it will need to be removed and replaced before anything else can happen. You may need to wait several days before materials can be ordered and shipped to your home. It may then take another day or two to repair the damage and get back to the originally scheduled project.

Weather Can Hinder a Contractor’s Plans

While most roofing projects stay on schedule, they can encounter delays due to adverse weather conditions. In colder months, ice or snow storms pose significant challenges, making it unsafe or even impossible to work on the roof. Additionally, shorter daylight hours during winter can prolong the project timeline. A roofing company may need to install a roof replacement over several days to ensure safety and efficiency.

Alternately, extreme heat and humidity during spring and summer can also impact the project’s timeline. High temperatures can make working conditions uncomfortable and may affect the performance of roofing materials. Asphalt shingles, for example, can become more pliable in heat, making them prone to damage during installation. This means the roofers will have to exercise more care in handling and installing them. Additionally, humidity can prolong the drying time of adhesives and sealants, potentially delaying progress.

Finally, severe weather events such as thunderstorms can disrupt roofing projects at any time of the year. Roofing contractors prioritize safety above all else, and work may need to halt if lightning is nearby. These interruptions, while necessary for worker safety, can extend the project’s completion time. It’s essential for homeowners to understand that weather-related delays are a common factor in roofing projects and to plan accordingly.

Changing the Type of Roof

Typically, a homeowner will use the same materials when replacing a roof. For instance, if you have asphalt shingles, you’ll replace them with a new asphalt roof. However, you may want to upgrade to a metal or tile roof. It’s possible to convert a shingle roof to a metal or tile roof, assuming that your home can handle the weight.

If your home can’t handle the weight as currently constructed, it may be possible to retrofit the property so that it can. Of course, it may take several weeks to get your home ready, plus another few days to actually put on the metal or tile roof.

Lead Time

Although it generally won’t impact how long it actually takes to replace your roof, the lead time will affect how long it takes before a new roof is on your home. Typically, contractors are busier during the late spring and early fall months.

Depending on when you want your roof replacement, you may face a lead time of several weeks to several months. Of course, even during a busier season, it may be possible to get your roof fixed in a timely manner. For instance, if you have a straightforward or easy roof to work on, it may be possible to squeeze you into the schedule at any time. It’s also possible that another customer will cancel or that another project will wrap up sooner than expected. However, if you have your recommended yearly roof inspection, a professional will inform you when you should schedule a replacement. This makes it possible to plan the project for when it is most convenient for you.

Don’t Forget About Cleanup

A roofing project will typically create a lot of debris that needs to be picked up before the crew leaves. Debris can include shingles thrown off of the house, nails and other objects that could cause safety concerns if left behind. In most cases, debris will be put into a waste bin or dumpster as work is being done. However, don’t be surprised if a final cleanup and inspection adds a few hours to the project’s timeline.
