Your roof is critical in keeping your family and home safe, comfortable, and warm. Sadly, it’s also often the element that’s left ignored until it starts to leak or show visible signs of damage. To get a clear understanding of your roof’s condition, the National Roofing Contractors Association recommends inspecting your roof at least twice a year.
Nevertheless, over time, any roof will need to be replaced. But exactly how much time are we talking about? This depends on the material and several other factors. In the article below, you’ll find a comprehensive guide to answer the question – how often should I replace my roof?
Understanding your roofing material
One of the most important aspects that impacts how often you should replace your roof is what it is made from. When building a new home or choosing a new roof, this is something you should consider. As you can expect, some materials are more durable than others, which allows them to withstand rough weather conditions better and longer.
Most homes in the US are equipped with asphalt roofs, which, unfortunately, have one of the lowest lifespans (around 20 years on average). If your roof has wood shingles, you’ll likely have to get it replaced less often, as they can last between 30 to 50 years. The most durable roofing materials are metal, roof tiles, and slate. If you’re lucky, these materials may even last longer than your home (50 to 75 years).
Other factors that influence your roof’s lifespan
Material isn’t the only aspect that determines the lifespan of your roof. In fact, it all starts with the quality of the contractor you hire. If your roof isn’t properly installed, it won’t be able to serve you as long as it potentially could. Even simple things like improper nailing or poor attic ventilation can cause issues along the way.
Another factor that plays a critical role is your area’s weather conditions. Let’s say you have an asphalt roof, and your home is in a region that experiences a lot of hail. In this case, your shingles might need replacement earlier due to granular loss. The same applies to cedar shake shingles, which may not last long in a very moist climate. Likewise, if you have a metal roof with an area of a lot of snow, the finish on your metal roof might come off quicker.
Signs you need a roof replacement
If you’re unsure whether the time has come for a roof replacement, look out for these signs.
Loose, missing, or damaged shingles: If you notice your roof’s shingles are curled, cracked, or some of them are missing, your home’s underlying structure may be exposed to water damage. Over time, this can cause leaks and other issues.
Other signs of wear and tear: As your roof ages, it will likely deteriorate. Watch out for sagging along the ridge and any moss or algae growth, and pay attention to granule buildup in your gutters. These are all signs your roof may need a spruce up or a replacement soon.
High utility bills. When homeowners notice their energy bill increasing, problems with roofing are usually not the first thing that pops into mind. However, when your roof’s shingles are nearing the end of their lifespan, they tend to absorb heat, which can lead to higher utility bills.
Pest infestation. Mice and rats are never welcome visitors, but did you know they can cause serious damage to your roof? That’s right. Pests can easily chew through wood or make holes in your insulation. This applies to bees, termites, birds, and squirrels too!
Water damage: Leaking ceiling or discoloration on your ceiling or attic is one of the most obvious signs your roof requires a replacement (and needs it very quickly). In the worst-case scenario, this can lead to disastrous consequences, like rot or mold growth, or even the collapse of your home’s structure.
Recap: How often should I replace my roof?
Replacing a roof can be a large undertaking, which is why many homeowners try to prolong it as much as possible. However, when the time has come for a roof replacement, it’s usually not wise to wait. That’s why it’s critical to regularly inspect your roof and perform routine maintenance to maximize its lifespan.
