If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.

The best material to sheath a roof will depend on your budget and if you require the strength of more robust materials. For most homes, the added strength is unnecessary, and oriented strand board, or OSB, makes sense. It’s inexpensive and robust enough for most roof types. Another popular but slightly more expensive option is plywood.

The proper specifications for furring strips can vary, so you should always consult the roofing manufacturer's guidelines or your roofer. However, general recommendations are as follows:

• Thickness: Furring strips are typically 1 to 1-1/2 inches thick, meaning standard 1-by or 2-by lumber works well. In areas with extreme winds, a thinner strip may be preferred to limit how much air can get under the roof and cause uplift. A thicker strip can add slightly more insulation but will also increase installation costs.

• Spacing: The recommended spacing for furring strips is between 12 and 24 inches apart on center. Proper spacing is crucial for ensuring good airflow, adequate drainage, noise reduction, and better energy efficiency. The ideal spacing can depend on the roof's pitch and the specific type of metal roofing being installed.

You can damage your shingles if you use the wrong type of paint on them. You should always use acrylic latex paint specifically formulated for shingles. Other types of paint may trap moisture, which can cause bigger problems like rot and mildew. Considering that roof replacement costs $9,100 on average, it’s definitely best to avoid making this mistake.

Besides using the right paint, remember that painting your shingles will require increased maintenance.
