How To Tell If You Need A New Roof

A new roof is about more than just fixing the existing roofing system on your house. If you’ve never had a roofing system installed before, or if it’s been a while since your last roof was constructed, it can be difficult to know whether, or when, you need a new one.

In this article, we’ll explore how to tell if you need a new roof, some frequently asked questions, and how to get started on replacing yours.

How To Tell If You Need A New Roof: Lifespan

There are a number of factors that affect your roof’s lifespan, including the materials used, quality of materials, maintenance, location, and climate.

The material used in a roof can be an indicator of how long it will last. Over time, certain types of roofs become brittle and susceptible to damage from wind or rain; therefore they may need to be replaced sooner than other types.

How long does roofing usually last?

The life expectancy of your roofing material depends on several factors, including the quality of installation, climate, and quality of materials. In general, shingles last anywhere from 20 to 50 years. Metal roofs can have a lifespan as long as 80 years. The lifespan for asphalt roofs is usually between 15 and 30 years, depending on the type and quality of the product used.

The average lifespan for a single layer of felt roofing is about 20 years. For multiple layers, it’s between 30 and 40 years in most climates (except those with extreme temperatures). If you live in an area where there are frequent snowstorms or high winds then your felt may not last that long before needing replacement because these types of weather conditions cause extra wear and tear on it over time which will eventually shorten its lifespan considerably.

For example, slate roofs have been known to last anywhere from 100 years to 250 years depending on where they’re installed. On the other hand, steel roofs have had lifespans ranging from 20-50 years depending on their quality and maintenance practices (which means regular inspections). Asphalt shingles are generally considered to be one of the least costly options but also one of the least durable – lasting only 8-12 years before they need replacement because they tend not to withstand harsh weather conditions as well as other materials like clay or concrete tile.

Is your roof older than 20 years?

One of the most quickly identifiable ways to know if you need a new roof starts when you examine the age of the existing roofing system. When your roof is older than 20 years, it is time to consider a new roof.

As a general benchmark, roofs generally last between 20 and 25 years. If your house was built before 1997 or so and you haven’t replaced the roof yet, it’s probably time to consider having a new roofing system installed.

Unsure if you need a replacement? These two things can help you determine if it is the right time:

  • Shingles that are curling up at the edges (especially if there are visible signs of cracking)
  • Small holes in shingles

How To Tell If You Need A New Roof: Weather Damage

Water damage can be caused by several different factors. In Colorado, a storm can blow through town, causing rainwater to find its way into the attic or crawlspace under your home.

One way or another, if there’s moisture in places where it shouldn’t be (like inside of walls), then it could mean serious trouble for your roofing integrity as well as the structure of your home overall.

Are there new leaks or other signs of water damage in the house?

You can also tell if you need a new roof if you see new leaks or other signs of water damage in your house.

Heavy and recent storms can lead to needing a new roof. If you live in an area that is prone to severe weather, such as Colorado, you should inspect your roof after any storm. The best way to do this is to hire a professional roofing company that will inspect the roof for damage, but if you wish to inspect it yourself there are some things you should look for:

  • Look for missing shingles or pieces of shingle that have been blown off
  • Check for any splits or tears in the wood structure underneath that may be causing leaks
  • Inspect vents and chimneys (if applicable)

Do you notice dark stains on your ceiling or walls from above your roofline?

Dark stains on your ceilings and walls are a sign of water damage. The stains indicate that there is an ongoing leak in the roofing system. As moisture gets into your home, it will cause mold to grow. Mold will leave dark stains on the ceiling or walls, which can lead to other problems such as allergic reactions and respiratory issues for occupants in your home.

If you notice these dark stains, it’s important to have them inspected by a professional roofer who can determine whether they’re caused by condensation or a leak in your roofing system.

How To Tell If You Need A New Roof: Craftsmanship Issues

Is the roof sagging, warped, curved, or bubbling?

If the roof is sagging, warped, curved, or bubbling, these symptoms are indicative of a damaged roof that needs to be fixed. Sagging is caused by missing nails, while warping is usually caused by age and moisture. Bubbling can occur in areas where there’s been an excessive amount of moisture for an extended period of time.

Is there visible deterioration in the nails holding down your shingles to the roof structure?

It may be difficult to tell if your nails are loose or missing without careful inspection. If you do notice that some are broken, the shingle will likely be falling off in pieces or become totally gone.

In this case, you have a need for a new roof!

Rusty shingles and nails can also indicate that it’s high time to call in a professional roofer. While rusty nails aren’t necessarily an indication of damage yet (they could just mean that they’re old), they should still be inspected by a professional because of how much water comes into contact with them as part of your home’s plumbing system.

Are any of the shingles cracked, curled up, or broken?

If you find that any of the shingles are cracked, curled up, or broken, this is a sign that something is wrong with your roof. If you don’t replace these damaged shingles ASAP, they will start leaking and cause additional damage to your home.

FAQ: How To Tell If You Need A New Roof


How do you know when it’s time to change your roof?

Recognizing the signs of an aging or damaged roof is crucial. Look for indicators such as missing or curled shingles, frequent leaks, granules in the gutters, sagging roof valleys, and daylight coming through the roof boards. If you notice any of these signs, it might be time to consider a roof replacement.

What is the life expectancy of a roof?

The life expectancy of a roof largely depends on the material used. Asphalt shingle roofs typically last 20 to 25 years, while wooden shingles can last 30 to 40 years. Metal roofs have a lifespan of 40 to 70 years, and slate, copper, and tile roofs can last over 50 years. However, factors like climate, maintenance, and installation quality can influence a roof’s longevity.

How often should I replace the roof of my house?

The frequency of roof replacement depends on the roofing material, environmental conditions, and how well the roof has been maintained. On average, homeowners might need to replace their asphalt shingle roofs every 20 to 25 years. However, with regular inspections and timely repairs, some roofs can last longer. It’s always a good idea to consult with a roofing professional if you’re unsure about the condition of your roof.

How do you know if your roof is in bad shape?

Several signs can indicate a roof in poor condition. These include:

  • Missing, broken, or curled shingles
  • A large amount of shingle granules in the gutters
  • Leaks or water stains on the ceiling or walls
  • Sagging areas on the roof
  • Moss or algae growth
  • Rusted or damaged flashing
  • Daylight visible through the roof boards

If you observe any of these signs, it’s advisable to get a professional roof inspection to determine the extent of the damage and the best course of action.
