Signs It’s Time to Replace an Asphalt Shingle Roof

Few homeowners relish the thought of replacing a roof. It’s important to be realistic about the need for roof replacements, though. While replacing a roof admittedly requires an investment, it’s much less expensive to have a failing roof replaced at the first sign of trouble than to wait until it begins to cause water damage, mold, and structural problems.

Minor and localized issues can usually be repaired. More extensive damage or ongoing wear usually needs to be addressed through a full roof replacement. The best way to tell if a roof can be saved is to schedule an inspection with a roofing contractor, but homeowners who want some reassurance that their money will be well-spent can also read on to find out about the most common signs it’s time for a new roof.

  1. Old Age

The average asphalt shingle roof needs to be replaced every 20 to 30 years. If the roof is approaching its 30th birthday, it may be more cost-effective in the long run to have it replaced now. Even if everything looks fine from the ground or an immediate repair seems minor, the roof may only have a few good years left in it before it fails completely.

  1. Curling Shingles

Curling shingles are a tell-tale sign that there’s water infiltrating into the roof deck. If the roof isn’t leaking yet, it will be soon. Whether the shingles are curling up at the edges or clawing in the middle, homeowners should plan on replacing their roofs within the next few years and should weigh the cost of temporary repairs carefully against the long-term benefit of a roof replacement.

  1. Many Missing Shingles

A few missing shingles in one area is no reason for panic. If the roof is still relatively new and the damage is localized, homeowners can typically have a patch installed, though it’s unlikely to match the colour and texture of the old shingles perfectly. It’s only when there are missing shingles across the whole roof or in many areas that most contractors recommend a full roof replacement.

  1. Many Cracked Shingles

As with missing shingles, a few cracked shingles can usually be replaced. However, if the problem isn’t isolated to one area, that’s a good sign it’s time to consider installing a new roof. Since shingle cracking is caused by wind damage, it’s rare to see this problem in isolated areas.

  1. Light or Leaks

If there’s already water leaking into the home or homeowners can see light through their roof decks, it’s well past time to call a roofing contractor. Small leaks can sometimes be repaired. If the roof is old or there are multiple spots where the sun is shining through, it’s better to have the roof replaced.

  1. Visible Sagging

Sagging roofs are indicative of potentially serious underlying structural issues. If homeowners do nothing, their roofs could fail completely, and on an alarmingly short time frame. Call a contractor to schedule an inspection and discuss replacement costs now before the problem gets any worse.
