6 Things to Know Before Replacing or Installing a New Roof

Installing a roof can be a daunting task for homeowners. You want to know all the facts and processes before you take the first step. A total roof replacement can cost as much as $8,000 in 2023; It is essential you get your money’s worth. Let us guide you through the process; here are some common queries people have regarding roof installation.

1. What Is the Difference Between Re-Roofing vs. Roof Replacement?

In re-roofing, one layer of shingle overlay is placed on top of worn-out shingles to improve their appearance and prevent leaks. It is the quickest and least costly way of replacement. However, building codes prohibit you from installing a third layer if you have two layers of shingles. In that case, you will need a roof replacement. 

In roof replacement, you remove old shingles and expose the deck. Then, you install a new underlayment or felt to protect the deck from water and other elements. Finally, you install new shingles on top. This lasts up to 20 years. 

Roof replacement addresses all problems with your roof, such as rot and holes, and repairs them, while re-roofing will cover them up. You save money in the long run because leaky roofs lead to water damage to flooring and drywalls, and fixing them on time can let you avoid costly repairs. 

2. Hire Local Roofing Contractors

Your roofing contractor should have a physical office in your area and a local phone number to contact them quickly when you have a roof problem. They know the specifics of your area; the installation codes, paperwork required, cost of materials, and more. 

Your local roofing contractor should be licensed; it may vary from state to state, but they should typically have a general contractor’s license. They should be insured with general liability, worker’s compensation, and vehicle insurance policy; otherwise, you will be responsible for paying the cost of damage. Your roofing company should follow safety training and protocols so no injuries may occur. 

3. What to Include in Your Roofing Contract?

Your roofing contract should cover all business details, including their physical address, insurance information, and details regarding the scope of work. This includes the process, labor, and materials needed to complete the job and the completion time. 

The contract should include a warranty so you won’t have to pay for roof repair costs if the roof is defective. You need to add payment schedules as well to avoid any financial issues. You should also have the option to terminate the contract and terms, such as compensation. Review the contract and negotiate when needed before signing, as it is binding. 

4. The Roofing Materials 

Roofing materials may vary according to the type of home, climate, personal preferences, and more. Among  the main components of your roof that may need replacing are the following: 

  • Shingles
  • Underlayments
  • Decking 
  • Drip edge 
  • Roof vents

You want to consider the material’s appearance, longevity, and cost. For example, asphalt roofing shingles are cheaper but have shorter life spans than metals or concrete. Traditional roofing materials such as slate or shake have both durability and longevity. These are more expensive, but they last longer and boost property value. 

5. Preparation Before Roof Replacement 

A few tasks you need to take care of include the following: 

  • Cut the grass so that roofers can mind pieces such as nails or screws dropped on the ground
  • Cut back tree branches encroaching on the roof
  • Move outdoor objects
  • Move vehicles to protect them from debris
  • Clear out the attic to prevent damage
  • Cover your pool
  • Remove wall hangings
  • Notify your neighbors about the potential disturbance

6. The Roof Replacement Process 

Your roofing contractor will deliver the materials the day before or the day of the replacement; you should store them in a dry area. The contractors will prepare your property for the tear-off by tarping the ground. After this, they will tear off your roof and install the new components in sections to save time. They will also remove leaves or blockages in the gutters during the tearing process. 

The next step for them is placing the underlayment and installing the drip edges and shingles in the installation process; ridge capping is placed next. The final step for the contractors is to install the vents for your roof’s ventilation system. Then begins the clean-up, which involves blowing your roof and gutters. The tarps that catch the debris are rolled up and disposed of in local landfills. Finally, the contractors may go over your property with a strong magnet to remove all the nails. 


You may ask yourself whether you really need to hire a contractor or if you can DIY it. However, the best course of action is to hire a professional because of the safety risks and complexities. Your roof’s quality depends on both the roofer’s workmanship and the quality of materials; consider both cost and quality to get the best results.
