A roof's ability to handle snow depends on its strength and the snow's weight, as wet snow is much heavier than dry, fluffy snow. While designs in snowy regions often allow for 35 to 50 pounds per square foot, a general guideline is that a typical roof can withstand about four feet of fresh snow, two feet of packed snow, or just one inch of ice. Factors like the roof's age, slope, and support structure also affect its capacity; newer, sloped roofs generally hold more weight than older, flat ones. Ice and ice dams add significant, dangerous weight. Because capacity varies, it is best to contact a professional roofing contractor or the original builder to determine the maximum snow load for your specific home.

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.

Roof sheathing can buckle from moisture damage, too much weight from roofing materials, or too much space in between rafters without thicker sheathing to compensate for the added distance. Bucking roof sheathing is a serious problem that can lead to a collapsed roof, so have a qualified roofer near you come to identify the problem as soon as possible. 

The roof overhang, also known as the eaves, does count as part of the roof’s square footage because it must be covered with the roofing material. The overhang is one of the reasons why you can’t base your roof's square footage on the square footage of the house. The roof square footage must also account for the pitch of the roof as well as the eaves.
