6 Signs Your Roof Needs Replacement Or Repair

6 Signs Your Roof Needs Replacement Or Repair
  • Opening Intro -

    Homeowners should always have roofing systems checked every year by a professional roofer to avoid spending a fortune later on repairs.

    As soon as your roof shows signs of damage, it's important to decide whether to repair or replace your shingles to keep the safety of those in your home, especially during harsh weather conditions.


In this article, you’ll learn how to spot the signs that your roof needs repair or replacement, so you can take action immediately.

1. Unpleasant Appearance of Your Roof

Your home’s roofing system is a major investment. That’s why it’s crucial to check the signs of your roof needing repair or replacement. One of the telltale signs that your roof needs to be prioritized is its unpleasant appearance.

A deteriorating roof looks worn out with missing, cupping, or curling shingles. It’s harder to prevent water from seeping into your home with missing shingles. Strong winds and falling tree branches can pull off shingles; repeated cycle of freezing and thawing can slowly damage shingles as well.

If you notice these signs, immediately contact a roofing Mississauga professional to repair or replace shingles.

Check out the other appearance issues of a deteriorating roof:

  • Decaying Shingles:

    Over time, your roofing materials will deteriorate, and you might notice decaying shingles. Cracks, splits, chips, peels, blisters, and curls should be replaced to avoid further roof damage.

  • Blistering Shingles:

    The roof surface bubble outward when gas or moisture accumulates inside the shingle. Debris, leaf, or a poorly ventilated attic may cause blistering. Intense exposure to sunlight worsens any existing blistering problem. Also, natural roof aging can be the culprit.

2. Damaged Flashing

A roof’s flashing is weather-proof, which is either made from rust-resistant metal, rubber, plastic, or felt. Professional roofers highly recommend galvanized steel because it is extremely durable and easy to install.

Aluminum-zinc coated steel flashing is available with more corrosion resistance as compared to galvanized steel. On the other hand, aluminum flashing is easy to bend and the perfect material for DIY installation.

Roof flashing is usually installed at intersections or terminations of the roof. You’ll find flashing along roof ridges, around dormer walls, around skylights, in low areas where roof pitches connect, and at vent pipes.

However, flashing may get damaged over time because of wind, acid rain, heavy snows, and the severe sun heat. After a severe weather event, it’s important to inspect your roof and check if you notice signs of flashing damage so you can contact a professional roofer to repair or replace it.

Check out the following flashing issues to look for when inspecting your roof:

  • Rust or Corrosion:

    Galvanized coatings are rust-resistant, but flashing materials also corrode over time because of the reaction with air, particularly salt air. Rusted roof flashing loses the ability to repel water and must be cleaned and sealed or replaced.

  • Small Holes:

    Small holes in your roof flashing can be due to wildlife or corrosion, which needs to be sealed to avoid a major roof problem.

  • Bends, cracks, or dents:

    Even a crack or bend looks minor issues, this damage could break galvanized coating on steel, weakening other metal structures. Once the metal structure of your roofing system is compromised, major corrosion strikes.

  • Missing Pieces:

    Racoons and other wildlife, strong winds, and storms may cause missing flashing pieces. Without a water barrier for your roof, you have to ensure that missing pieces are replaced.

  • Internal Leaks:

    Internal leaks near fireplaces, windows, attic, or skylights are signs of damage.

  • Staining or Mold on Fascia Boards:

    Incorrectly installed drip edge flashing may cause staining or mold on fascia boards.

3. Signs of Poor Craftsmanship

Investing in a new roof makes a great solution if you have an old and worn-out roof. However, some roof problems could be brought about by poor craftsmanship. Signs of poor-quality workmanship include excessive patching, two or more layers of shingles, or shingles that don’t seem to fit but are forced to fit together.

In the past, installing new shingles on top of old, existing shingles was common practice. It was done to save time and money. However, this practice has been abandoned because it could void the warranty of new shingles. It could result in severe water damage to your home. Also, a poorly installed roof could significantly affect its life span.

4. Rotting or Cracks on Plumbing Vent Boots

Inspect plumbing vent boots for rotting, cracks, or broken seams. Plumbing vent boots are either made of plastic, metal, or combined plastic and metal units. Look for worn out or rotted rubber boot that surrounds the pipe. If you see these signs, contact a roofer to fix the problem because water may enter the house, causing major problems.

5. Shiners

Sometimes ceiling stains and flow marks are fairly small. Inspect the underside of your roof for ‘shiners’ or a nail missing the framing member. Moisture escapes into the cold attic, and the rooms below condense on cold nails, causing shiners.

other valuable tips:

When you climb up the attic on a cold night, you’ll notice shiners or nails looking shiny white because they are frosted. The frost melts and drips as the sun heats your attic during the day, and the nails frost up during the night. It’s crucial to rule out the source of shiners by calling a professional roofer to check any damage in your roofing system.

6. Ceiling Stains

A leaky roof causes water stains running down walls or extending across ceilings. It’s difficult to keep track of leaks, so roof leak repair is highly recommended. Even small leaks over a short time could result in major problems, including rotted sheathing and framing, mold, damaged ceilings, and destroyed insulation.


Your roof needs repair or replacement if you notice any of the signs showed above. Ceiling stains, shiners, and rotting or cracks on plumbing vent boots are signs of roof damage. Also, obvious signs of roof problems include damaged shingles and flashing. Sometimes you’ll encounter signs of poor craftsmanship, especially in old houses that need a new roof replacement.
