No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.

Venting a gas water heater out of the roof is preferable in most cases. Heated exhaust gases naturally rise, so a vertical vent pipe is efficient. If you’re trying to vent through a pipe exiting a wall, the angle of the pipe may be more horizontal than vertical, making the venting system less effective. If you go through a wall, you may need to add a fan to ensure a successful expulsion of the gases outdoors.

Yes, materials like cool roofs and solar shingles may be considered.

It’s possible to install your chimney cap in some areas, but it’s usually better to hire a professional. Before you attempt a DIY chimney cap installation, check to see if your local building department requires a permit. If it does, you should hire a professional to pull the permit and complete the work for you. Even if you don’t need a permit, getting up on your roof is dangerous, especially if you have an aggressive pitch or slippery roof material, like metal. Hiring a chimney professional guarantees the job is done correctly and keeps you safe from injury.
