You can put new shingles over old shingles, but most municipalities only allow for two layers of shingles before you have to rip off the old roof and start fresh. In some areas, only a single layer of shingles is allowed due to the weight a bundle of shingles adds to your structure. In most cases, it’s a good idea to remove your old shingles before you install new shingles, especially if you suspect that a roof leak may have compromised the decking underneath.

A roof replacement will usually include removal of your old roof, shingle replacement, and a new roof underlayment, but it may only include adding new shingles if you’re layering new shingles over the old shingles. If you have signs of roof leaks or your roofer finds water damage to the roof decking underneath your old roof, it can also include replacement of the OSB or plywood decking that lays over your rafters and supports the roofing material above.

Architectural shingles typically last between 20 and 30 years, though most homeowners should plan on replacing them every 20 to 25 years. While some manufacturers offer warranties for 30 to 50 years, especially for extreme weather, achieving such a long lifespan is rare. The actual lifespan can be shorter in areas prone to strong winds, hailstorms, or other extreme weather. It is recommended to replace your roof before it reaches the end of its life to reduce the risk of roof failure, leaks, and costly property damage. Scheduling regular roof inspections will help you determine your roof's remaining life and identify the best timeline for replacement.

A well-maintained tile roof can last anywhere from 40 to over 100 years, with its exact lifespan depending on the material and level of care. Proper maintenance, which includes keeping the roof clean, free of debris, and performing routine repairs for any cracked tiles, is crucial for longevity. The lifespan varies significantly by tile type:

• Clay, terracotta, and slate tiles are highly durable and can last over 100 years.

• Concrete tiles typically last from 30 to 100 years.

• Metal tile roofs generally last between 40 and 70 years.

• Composite tile roofs have a lifespan of 20 to 50 years.

Be aware that maintenance for a tile roof can sometimes be more expensive than for an asphalt roof.
