Signs It’s Time to Replace Your Roof

A scattering of buckets and pots catching water dripping from your ceiling during a rainstorm is a certain indicator that your roof needs immediate attention, but how do you know when it’s time to replace your roof?

It’s prudent for homeowners to spot check their roof at least twice a year, usually in the Fall and again in the Spring. Since different roofing materials weather at different rates, how often you’ll need a full inspection depends on what your roof is made of. Having a professional take a look at your roof every five years make good sense.

With that in mind, these factors may prompt you to call a professional and get your roof replaced. (Bonus: doing so will likely reduce your home insurance bill.)

Your Roof’s Age

A good starting point to decide if you need to replace your roof is its age. A roof should last about 20 years on average, but there are several factors which can impact that number, including the roofing materials that was used. The following list outlines is the typical longevity of certain roofing materials:

  • Asphalt roll roof: 5 to 10 years
  • Composite shingle roof: 15 years
  • Wood shingle roof: 25 years
  • Standing seam metal roof: 30 to 50 years
  • Wood shake shingle roof: 35 to 40 years
  • Clay tile roof / Spanish tile roof: 40 to 100 years
  • Slate roof: 100+ years

The maintenance of your roof also matters. For example, a roof installed over an existing layer of shingles should be replaced after no more than 20 years.

Curling Shingles

Shingles need to lie flat against the roof to do the job they are intended to do. If they are curling, buckled, or damaged, you’re headed for issues sooner rather than later. You can use a decent pair of binoculars to check the shingles from the ground. You can also check gutters and downspouts for shingle granules. Roofs that are nearing the end of their life tend to shed these easily after a heavy rain.

Rusted Roof Valleys

A roof valley is the V-shaped metal channel found in the “joints” of the roof. The valley makes it easier for snow and rain flow off your roof and into the gutter. If the valleys are showing rust, your roof can leak into your home.

Missing Shingles or Tiles

If your roof is missing shingles or tiles, the best case scenario is that you need to repair the missing components. However, this might be another sign your roof’s useful days are numbered and it’s time for a professional to have a look.

Gaps in Flashing

The flashing around the vents, skylights, and chimney on your roof help fortify these openings against leaks. That’s why it’s extremely important to make sure there are no cracks or breaks in the flashing, especially if it’s made of cement or tar, which erodes over time. Metal flashing typically has a longer life.

Daylight through Roof Boards

If you think it might be time for a new roof then a trip to your attic is in order. Check the roof deck and look for daylight through the roof boards – this is a sign that water has an entry point into your home.

Sagging and/or Moss

A roof that’s trapping moisture is usually one that needs a replacement. You can spot signs of moisture in your roof a few ways:

  • Examine the insulation in the attic – if it’s moist, you likely have a roof leak.
  • Check for moss, mold, and fungi on and around the roof.
  • Look for sagging in the roof and for rotting boards.

Just because you find some damage doesn’t necessarily mean you need to replace the roof entirely. But if you see the signs listed in this guide, it’s probably best to call a professional and have your roof inspected and to get an expert opinion.
