How To Know When Your Porch Needs A New Roof

The roof of a porch takes damage from wind and water throughout the year, but that damage often goes unnoticed until a leak or other similarly serious problem develops.

Naturally, you want to replace your porch’s roofing material before it starts allowing water in or otherwise loses structural integrity. But how do you tell when the roof has entered the “danger zone” and the cost of replacement is justified?

A realistic maximum life expectation for a standard porch roof with shingles is about two decades from installation. That’s the point at which even the sturdiest materials will generally degrade to the point that you’ll see leaks and serious damage develop. If you live in an area where you endure heavier rain, wind or snow than usual, however, you can knock up to five years off that expected lifespan. Poor ventilation will also decrease the life expectancy of a roof significantly.

If your roof is entering the danger zone in terms of age, or if you have reason to suspect it’s been damaged, look for the following signs:

  • Look for indentations or concave spots in the roof. These are signs that an unseen leak has been rotting away wood in the roof for some time. If you see these, you should discontinue use of the porch until the roof is replaced as it could potentially fall apart on you.
  • Dark streaks or trails on the underside of the porch roof are usually a sign not only of water damage, but that mold is growing in the area.
  • Look for problems with the shingles. The most obvious signs would be shingles that are completely gone or that are showing obvious signs of damage like missing chunks, being broken in half or turning up at the edges. Also check your downspouts for bits of shingle, however, as that’s a good “early warning” sign that there’s trouble in that area.
  • Slate tiles will last longer than standard tiles, but they do decay and fail eventually. A quick check to see what condition a slate tile is in is to simply knock on it with your knuckles. A tile in good condition should have a bit of a vibration or echo to the sound it makes; a tile that is aged past usefulness will sound more like rapping on concrete.

A porch roof failure represents not only a much greater expense than replacing it before things get out of hand, but also a serious safety issue as well. If you have any doubts about the integrity of your roof, it’s best to contact a qualified professional to verify.
