It’ll cost $14,000 to $40,000 to put a metal roof on a 2,000-square-foot home, depending on the materials and the size of your roof. A flat roof on a 2,000-square-foot home uses far fewer materials than a steeply pitched roof. Roofs with multiple angles, corners, and tight spots also cost more, as they require more material, cuts, fasteners, and flashing, all of which costs more in both materials and labor.
In most cases, you should call a professional to fix a hole in a metal roof. However, if you have the right tools and skills, and are comfortable working at height, here are the general steps you'd take to fix a small hole in a metal roof:
Clean and dry the area, including a 6-inch margin around the hole.
Scuff the metal to allow for good adhesion.
Measure and cut the repair patch at least 3 inches bigger than the hole you're repairing.
Install the patch using an outdoor-rated urethane sealant, ensuring no gaps exist in the sealant.
Use sheet metal screws to secure the patch.
If necessary, paint the patch to match the rest of your roof.
No, if properly installed, metal roofs do not leak more than shingle roofs. In fact, because of metal roofs' nature, they shed snow and ice to prevent the buildup you commonly see on shingles that damage the structure and often cause leaks. Metal, unless corroded, is also waterproof, so water can't get inside and cause damage.
No, a properly structured metal roof is not loud in the rain. With a roof deck, underlayment, and insulation in place, a metal roof is silent when it's raining because its full roof structure reduces reverberation and noise. The more textured a sheet of metal roofing, the less noise it creates.
