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.

Depending on the type of damage your roof shingles have, you may be able to simply repair them without having to replace them. However, if there are more than a few to repair, replacement is likely the easier option. You may only need to replace a few of them. Repair shingles by applying roofing sealant directly under the shingle's damage and then directly over it.

• Waterproofs your roof for an average of 10 years

• Easy to purchase and transport

Cons:

• Less durable than asphalt shingles

• Not as aesthetically pleasing as shingles, wood, or clay tiles

• Not preferred for a higher home resale value

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.
