Why Should You Raise a Roof on a Garage?

There are many reasons why you should raise a roof on a garage. One of the most important reasons is to protect your vehicles and other belongings from the weather. If you live in an area that experiences a lot of rain, snow, or wind, raising your garage roof can help keep your belongings protected.

Another reason to raise your garage roof is to create more storage space. By raising the roof, you can create a loft area that can be used for storage.

Things to Consider Before Raising a Roof on a Garage

1. Make Sure the Roof is in Good Condition

The most important thing to consider before raising a roof on a garage is the roof’s current condition. If the roof is in bad shape, it’s best to repair or replace it before raising the roof. This will ensure that your garage is protected from the elements and will last for years.

2. Check the Size of the Garage

It’s important to check the size of your garage before raising the roof. Ensure there is enough room to comfortably park a car in the garage and walk around inside. If there isn’t enough space, you may need to reconsider raising the roof.

6. Always Work with a Professional

When it comes to raising the roof on your garage, it’s always best to work with a professional. They will have the experience and knowledge to get the job done right, but they’ll also have the proper tools and equipment. Trying to do it yourself could lead to costly mistakes and could even be dangerous.

Step by Step Guide: How to Raise a Roof on a Garage

Step 1: Assess the Current Roof Structure

Begin by assessing the current roof structure of your garage. Determine the type of roof (gable, hip, flat, etc.), the materials used, and the overall condition of the existing structure. Take note of any damage or wear that may need to be addressed during the roof-raising process.

Step 2: Determine the Desired Roof Height

Decide how much you want to raise the roof of your garage. This decision will depend on your specific needs and goals for the space, such as adding a loft, increasing storage, or improving the overall aesthetic. Keep in mind that raising the roof too much may require additional permits or may not be allowed by local building codes.

Step 3: Consult with Professionals

Raising a garage roof can be a complex and potentially dangerous project, so it’s essential to consult with professionals before proceeding. Reach out to architects, structural engineers, and experienced contractors to discuss your plans, obtain their input and advice, and get cost estimates for the project.

Step 4: Obtain Necessary Permits and Approvals

Before starting any construction, make sure to obtain the necessary permits and approvals from your local building department. This may include submitting plans, completing forms, and paying fees. You may also need to adhere to specific building codes and regulations, so familiarize yourself with these requirements before proceeding.

Step 5: Develop a Detailed Plan

With the help of professionals, develop a detailed plan for raising the roof on your garage. This plan should include:

  1. A structural analysis of the existing roof and walls to determine their ability to support the new roof height
  2. A list of materials and tools needed for the project
  3. A timeline for completing the project
  4. A budget for the project, including labor and material costs

Step 6: Gather Materials and Tools

Once you have a plan in place, gather the necessary materials and tools for the project. This may include lumber, roofing materials, fasteners, and other construction supplies, as well as specialized tools like a crane or hydraulic jacks to lift the roof.

Step 7: Prepare the Garage for Construction

Before starting construction, prepare the garage by removing any items that may be in the way or could be damaged during the process. This may include vehicles, tools, equipment, or stored items. Also, ensure that the area around the garage is clear and accessible for workers and equipment.

Step 8: Remove the Existing Roof

With the help of experienced professionals, carefully remove the existing roof from your garage. This may involve cutting through fasteners, removing roofing materials, and disassembling the roof structure. Dispose of any debris or waste materials responsibly.

Step 9: Construct the New Roof Support System

Following the detailed plan and under the guidance of professionals, construct the new roof support system for your garage. This may involve building new walls, adding support beams or columns, or reinforcing the existing structure to accommodate the increased height.

Step 10: Lift the Roof to the Desired Height

Using specialized equipment, such as a crane or hydraulic jacks, carefully lift the roof to the desired height. Ensure that the roof is level and secure before proceeding.

Step 11: Secure the Roof to the New Support System

Once the roof is at the desired height, secure it to the new support system using appropriate fasteners and hardware. Double-check that the roof is level, secure, and properly supported before proceeding.

Step 12: Install the New Roofing Materials

With the roof in place and secured, install the new roofing materials, such as shingles, metal panels, or membrane, following the manufacturer’s recommendations and best practices. Ensure that the roofing materials are properly installed to prevent leaks and provide long-lasting protection.

Step 13: Inspect and Seal the Roof

After installing the new roofing materials, conduct a thorough inspection of the roof to ensure that everything is properly installed and secured. Check for any gaps, loose materials, or other issues that could compromise the integrity of the roof. Seal any seams, joints, or other areas where water may penetrate, using appropriate sealants or flashing materials.

Step 14: Install New Siding or Finish Materials (if necessary)

If you’ve raised the roof significantly, you may need to extend or replace the siding or finish materials on the garage walls to match the new roof height. Choose materials that complement the overall aesthetic of the garage and your home, and follow proper installation procedures to ensure a professional appearance and long-lasting results.

Step 15: Install New Gutters and Downspouts

With the new roof in place, install new gutters and downspouts to manage rainwater runoff effectively. Make sure they are properly sized, securely attached, and correctly sloped to direct water away from the garage foundation.

Step 16: Update the Garage Interior

With the exterior work complete, turn your attention to the garage interior. Update the space as needed to accommodate the increased height, such as adding a loft or installing additional storage solutions. You may also need to update lighting, insulation, or other aspects of the interior to ensure the garage remains functional and comfortable.

Step 17: Clean Up the Worksite

After completing the roof-raising project, thoroughly clean the worksite, removing all construction debris, tools, and equipment. Dispose of waste materials responsibly, and return any rented equipment promptly.

Step 18: Conduct a Final Inspection

Once everything is complete, conduct a final inspection of the garage to ensure that the roof-raising project has been executed properly and that all components are functioning as they should. Check for any remaining issues or concerns that may need to be addressed.

Step 19: Maintain the New Roof

To ensure the longevity of your new garage roof, develop a regular maintenance routine. This may include cleaning the gutters and downspouts, checking for damage or wear, and making necessary repairs as needed. By maintaining the new roof, you can protect your investment and enjoy the benefits of a taller garage for years to come.

Raising the roof on your garage is a complex and challenging project that requires careful planning, professional assistance, and attention to detail. By following these steps and working closely with experienced professionals, you can successfully increase the height of your garage roof, adding value and functionality to your home.
