3 critical signs you need to replace your roof

Admitting you need to replace your roof is a big financial decision! That’s why it can be easy to put it off until the last minute. Here’s what the last minute looks like.

Knowing when it's time to replace your roof can be tough.

Replace your roof when you see any of these 3 signs:

Evidence that you need to repair or replace your roof is sometimes subtle and happens over time.  One thing is certain: if you wait until your ceiling starts to turn weird colors or there’s water dripping on your head, you are have waited too long. By the time roof damage shows itself inside your home, you’ve missed your chance to simply replace your roof. Now you’re going to need to fix the rest of your house, too.

That’s why the first critical sign in our list is actually a collection of subtle evidence of roof damage.

1. Subtle roof damage

Look for these signs at least twice per year to identify problems before they becomes more expensive.  Roof damage only gets worse with time!

  • Shingle condition:  Missing or damaged shingles can allow water to penetrate into the sheathing layers and lead to rot. Look for uneven shingle lines, curled, loose or torn shingles.  If you see your roof sagging, it’s a pretty clear sign the under layer is rotting.
  • The calendar. That’s right — if the roof was installed properly with good materials, you can expect 20-25 years of life unless you get storm damage.  If a roof is nearing the end of its useful life, it is probably time to consider replacement.

2. Double Layering

Double layering is not the way to replace your roof.

The cheapest way to replace a roof is to place a second layer of roofing material over the first one.  While you may save some cash by (temporarily) avoiding a roof replacement, there are many reasons to think twice before going this route.

First, you really don’t know the full extent of roof damage unless you remove all roof material down to the sheathing.  Placing a second layer of shingles over an already rotten sheathing will shorten the life of your new roof and cost you much more in the long run. Besides, removing two layers of roofing material will drive up the cost when you decide to replace your roof in the future.

That’s not all. Consider:

“Apart from the problems that can go unnoticed during the actual shingle-over, there are long term effects to consider, as well,” note the roofers at The Roofing Dog in Champaign, Illinois. “For instance, instead of just one roof on your home, you now basically have two. That’s a lot of weight, putting added stress on the roof decking. Also, two layers of shingles are going to attract a lot more heat than just one layer, which can lead to the shingles prematurely deteriorating. What about all that dark algae growth and bacteria on the original layer of shingles? Now all of that is trapped under a second layer of shingles, again having the potential to shorten the lifespan of the top layer of shingles.”

Concludes The Roofing Dog: “If you haven’t noticed yet, we are not fans of shingle overs at all.”

Keep in mind that with the overlay you cannot install an ice barrier that must adhere to wood decking. Check with your insurance company about any restrictions on coverage, too.

3. You’re Selling Your Home

Selling your home is a sign you need to replace your roof? Oh, yes. A compromised roof can complicate a housing sale very quickly.  Even in a brisk “seller’s market,” a damaged roof makes the home less desirable to buyers.

Your first thought may be to sell the house as is and let the buyer worry about it.  Most of the time, the strategy will cost you a lot of money.

  • Buyers want more than the price of the roof for a discount. .
  • Lenders don’t want to extend a mortgage on a house with roof damage.
  • Insurance companies inspect homes and deny coverage to houses with bad roofs

Bottom line: Unless you are willing to take significantly less than your home is worth AND limit buyers to those who offer cash, a good roof is required to sell your home.*
