How do I know if my roof is in bad condition?

Oct 6

Several warning signs could indicate the end of your roof's lifespan. These warning signs can indicate that your roof is in serious trouble. It is essential to pay attention to them and take action when you notice problems. Roof replacement is costly and time-consuming, but it is essential to owning and maintaining your home. 

You may need to repair more than the roof if you don't act quickly. You don't want to ignore the signs that your roof may fail. This could lead to additional costs and even cause harm to your health and safety as well as that of others living under your roof. If you observe any of these conditions, you may need to replace your roof.


Not a good idea to climb onto your roof for an inspection. To inspect your roof, look up using binoculars. Woodbridge Roofing Company can also conduct a free inspection.

There are several loose or missing shingles.

It could be storm damage or because your roof is old. Your roof isn't as helpful when shingles fall off or become loose.

Shingles are cracking, curling, drying, or blistering.

These signs usually indicate a roof that is past its prime and needs to be replaced. High humidity (contact with too much moisture) could also cause blistering. A poor roofing ventilation system often causes this.

The roof is falling.

Sagging roofs could indicate several things. It could be that your roof is weakening and deteriorating, it could have been improperly installed, or it could be supporting too much weight (snow or ice). Roof sagging can be a sign that your roof needs replacement. It could fall if you do not act quickly.

Your roof has dark/dirty spots.

When granules start to fall off shingles, darkened areas are shared. These are signs that your shingles have become worn and need to be replaced. Also, dark patches on your roof could indicate algae or moss growth. These should be removed immediately.

Granules are in your gutters.

Shingles that begin to lose their granules indicate that they are no longer as effective as they used to be. As they age, shingles lose more granules.

There are many exposed or loose nails.

Nails that start popping out of their place can cause water penetration into the roof. You might need to replace your roof sooner than you thought because of the damage caused by moisture.

Water damage in your attic or home.

Water leaking in any part of your house or attic could indicate that your shingle roof flashing is worn or your underlayment has become inadequate. Inadequate roof ventilation can lead to mould and mildew.

Flashing may be missing or damaged in certain areas.

Flashing should be around any projections that intersect your roof, such as your chimney. Water can easily seep into your home if the seal around these structures is damaged or broken.

Your roof has been in place for over 20 years.

An asphalt shingle roof will last between 20-25 years. You might need to replace your roof sooner if your roof was placed on top of an older roof (shingles on top shingles).

Your cooling and heating bills are significantly higher.

It could be due to insufficient attic ventilation or a leaky roof that allows bad air in but good air out.
