When you own a home, a significant amount of time is put into preventing issues. Maintenance is essential for the appearance and function of your home, not to mention, it benefits your wallet. While it can be tempting to put off repairs to avoid costs right now, this will only mean you will be paying more in the future. 

That being said, the right choice for your home won’t always be obvious. For example, when it comes to your roof, there are occasions when you will need to replace a roof altogether, but there will be others when simply repairing the damage is perfectly acceptable. So how do you know which is your scenario? That will depend on several different variables, such as the nature of the damage and how much of the roof is damaged. 

Replacing Some Shingles

Not all roof damage will require a hefty repair bill; sometimes, if you can catch an issue early, it’s as simple as replacing some shingles. Your shingles are designed to last for decades, and most roofing systems are intended to last for as long as you own your home. 

Before you decide that you simply need to replace some shingles, it’s important to contact your friendly neighborhood roofer for an inspection. There’s a difference between a few shingles between whisked off your roof in a windstorm and a leak that is infiltrating your attic. You’ll want to make sure you know the depth of damage beyond the surface before you simply nail some new shingles onto your roof. 

If your roof is missing shingles, do not wait to replace them. Shingles protect the roof’s decking from the elements. Even a small exposed area can let water seep into the underlayment and then into the deck, which will then cause rot and leaks. 

Patching Your Roof 

If your roof has been damaged, it’s understandable that you may wonder whether or not you can get away with patching it or if you will have to replace it entirely. While patching your roof is a viable option in some cases, you’ll still run into the same risks as you do with replacing shingles. 

This means that you should make sure to speak with a knowledgeable roofer before taking on the patching job yourself. With a professional inspection, you can know whether or not a patch will help extend the life of your roof, or cause more harm than good. When you call Goliath Roofing and Remodeling for a roof inspection, we will examine both the exterior of your roof as well as your attic to determine if moisture has gotten into your interior. 

Even if patching would hypothetically address your specific issue, it’s likely not the most aesthetically pleasing option. It can be difficult to seamlessly blend new shingles in with the older ones. 

Roofing Over Your Current Roof

Some people see their roof damage and come to us to ask if they can simply roof over the current roof. Though it might seem like this will save you money, in reality, this is equivalent to putting a giant bandaid on top of your house. As may be able to cover the problem, but the damage is still underneath. 

Hypothetically, you can pursue this option because building codes dictate that you can have two layers of shingles on your roof. More than two layers, however, puts too much weight on the top of your house, risking damage. 

In addition, you should consider the inevitability that you will need your roofing replaced eventually, particularly if it is already damaged. If you have two layers of shingles, you will have to pay twice as much to get them all ripped off the top of your home. And, if you do face a leak, you now have a twice as involved scavenger hunt to pursue before finding the source. 

Finally, putting shingles on top of your current shingles will void your manufacturer’s warranty. If you have a problem in the future, you won’t be able to use your warranty to cover the cost of repairs. 

Replacing A Roof 

So what about when it’s time to install an entirely new roof? Your decision will be based on a few different factors that you should take into careful consideration. 

  • Water damage. Once water seeps into your shingles, it doesn’t take long for it to make its way inside your home, where it can cause some serious damage to your home. If you see brown spots on the ceiling, peeling paint, or mold inside your home, this is a clear indication that it’s better to address the problem at its source and replace the roof. 
  • Natural disasters. In the event that your neighborhood has recently experienced a violent storm such as a hurricane, damage may warrant a complete roof replacement. This can also be true if you have recently experienced a very rough winter. 
  • Age. There’s a difference between when your roof is five years old versus when it is 20. If your roof is leaking and it was installed five years ago, it’s likely because the materials were defective or the workmanship shotty. Ideally, a simple repair would help. Alternatively, if your roof is already 20 years old, it is already at the end of its expected lifespan, and it is due for replacement. 
  • Materials. The roofing materials used will also dictate whether you should repair or replace your roof. While an 80-year-old slate roof likely has several decades left, a metal roof of the same age is in desperate need of replacement. The most common type of shingle, asphalt, generally only lasts 15 to 25 years, though the latest generation of high-end asphalt shingles can last up to 50 years.
