While there are many benefits to installing a metal roof on your home, there are some downsides, too. Zinc roofs, in particular, are susceptible to corrosion from overly salty air directly near coastal areas. Another potential downside of zinc roofing is that it must be allowed to expand and contract with the weather. This means special attention is necessary to how it's fastened to the home to avoid issues. 

Though roof coatings can last up to two decades, it’s a good idea to recoat your roof every four to six years. This is especially important if you have a built-up roof, which is vulnerable to moisture issues. Inspect your built-up roofs annually to make sure they don’t need a new coat.

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.

Generally, hailstones that are one inch in diameter or larger can cause significant damage to a roof. However, smaller hail can also cause damage, particularly when accompanied by strong winds, if it strikes an aging or poorly maintained roof, or if hailstorms are frequent in your area. Hail that is ¼ inch (pea-sized) or smaller poses a minimal risk of immediate, permanent damage, but cumulative impacts can cause deterioration over time. The extent of the damage also depends on the roofing material; hail-resistant tiles like slate or certain types of asphalt shingles can withstand impacts better than other materials. If you are concerned about potential damage after a storm, it is always a good idea to have a professional roofer conduct an inspection.
