The minimum recommended slope for a porch roof is 1/4:12, which means 1/4-inch of rise every 12 inches of run. Slopes of 3:12 and 4:12 are more common and provide faster drainage for runoff. Make sure to choose a pitch that’s appropriate both for the climate in your area and the type of roof material you install. Hire a roofer if you need help determining what the right roof pitch is.

The purchase price of 3-tab shingles is less than that of other material varieties, such as architectural shingles. However, 3-tab shingles generally last far fewer years than even the least expensive architectural ones. Other roofing types, such as metal or clay, also cost more than 3-tab shingles. However, if you plan to stay in your home for many years, the long-term cost of any of these options can compete with 3-tabs because of their longevity.

When choosing a roofer to install a green roof, look for someone with experience who specializes in green roofs. Rather than looking for a standard roofing contractor, you'll want to find a company that specifically offers green roofs. That company will have people on staff, such as a landscape architect, who understand the types of plants that thrive on rooftops.

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.
