Architectural shingles typically last between 20 and 30 years. While some manufacturers provide warranties for 30 to 50 years, particularly for extreme weather, achieving such a long lifespan is uncommon. The actual life of your shingles can be shorter if you live in an area prone to strong winds, hailstorms, or other severe weather. To avoid the risk of roof failure and costly water damage from leaks, it is recommended to replace your roof before it reaches the end of its expected life. Scheduling regular roof inspections every few years is a good way to assess your roof's condition and determine the best timeline for replacement.

In most cases and locations, roofs with a single layer of asphalt roofing shingles won't require roof removal before installing a metal roof. However, underlayment may be necessary on roofs with moderate shingle damage. Heavily damaged roofs or ones with multiple shingle layers will most likely require removal before a metal roof can go on.

A roof replacement can take anywhere from one to 14 days. For most homes, a full replacement that includes tearing off old materials takes about one to two days, though the average project can last up to 12 days. The exact timeline depends on several factors, including the roof's size and complexity, the type of roofing material, the crew size, and weather conditions. Certain materials take longer to install; for example, metal roofs can take seven to 14 days because the material is more difficult to work with than asphalt shingles, wood, or tile. A re-roofing project, where new shingles are installed over old ones, can take half the time or less. It's also important to factor in the time needed to obtain necessary permits. A professional roofing contractor will typically complete the job faster than a DIY approach.

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.
