Missing Shingles


One of the most noticeable problems with a shingle roof is when you spot missing shingles. These gaps can lead to leaks and water damage. Here’s what you can do:

🔍 Identification

Examine your roof for any bare spots where shingles used to be. Keep an eye out for shingle granules in your gutters, a sign that shingles may be deteriorating.


Replace the missing shingles with new ones that match your existing roof. Ensure proper alignment and secure them with roofing nails.

Damaged or Curling Shingles

Shingles that are damaged, curled, or buckling can compromise the integrity of your roof. These issues often arise due to weathering and age.

🔍 Identification

Look for shingles that are cracked, split, or have curled edges. Pay attention to any shingles that appear discolored or worn.


Replace damaged shingles promptly. Lift the damaged area, apply roofing adhesive, and press the shingle down. Nail it in place and use a roofing sealant to secure the edges.

Leaking Roof

A leaking roof is a homeowner’s nightmare. Water stains on your ceiling or walls, mold growth, and structural damage are all potential consequences of a leaking roof.

🔍 Identification

Inspect your attic and interior for water stains or signs of moisture. On the roof, check for damaged or deteriorated flashing, which can be a common source of leaks.


Depending on the severity of the leak, you may need to replace damaged shingles, repair flashing, or patch small holes with roofing cement and a patching fabric.

Algae or Moss Growth


Algae and moss can take root on your shingle roof, especially in damp or shaded areas. While it may not be an immediate threat, it can detract from your roof’s appearance and affect its longevity.

🔍 Identification

Look for green or black streaks, patches, or fuzzy growth on your shingles. These are signs of algae or moss infestation.


Mix a solution of water and bleach (1:1) or use a commercial roof cleaner to eliminate algae and moss. Gently scrub the affected areas, rinse with water, and consider installing zinc or copper strips at the roof’s ridge to prevent regrowth.

Damaged Flashing

Flashing is the material that seals the joints and transitions on your roof, such as chimneys, vents, and skylights. Damaged or deteriorated flashing can lead to leaks.

🔍 Identification

Check for loose, cracked, or rusted flashing around roof penetrations. Inspect the seals and edges for signs of wear.


Replace damaged flashing with new, properly fitted flashing material. Ensure that it is securely attached and sealed to prevent future leaks.

Ice Dams

Ice dams occur in cold climates when snow melts on the warm parts of your roof, then refreezes at the eaves, creating a barrier that prevents proper drainage.

🔍 Identification

Look for icicles hanging from your roof’s eaves, as they are a sign of ice dams. Inside your home, check for water stains and leaks near the eaves.


Prevent ice dams by improving attic insulation and ventilation. Remove excess snow from your roof using a roof rake, and consider using heating cables to melt ice in problem areas.

Granule Loss

Shingle granules serve as protection for your roof, so when you notice significant granule loss, it’s a sign of aging and potential problems ahead.

🔍 Identification

Examine your gutters and downspouts for an accumulation of shingle granules. Inspect your shingles for bare spots.


If the loss of granules is extensive and your shingles are nearing the end of their lifespan, it may be time for a roof replacement. Otherwise, consider applying a roof coating to extend their life.

Sagging Roof

A sagging roof is a serious issue that could indicate structural problems. It’s essential to address this immediately to prevent further damage.

🔍 Identification

Stand back and visually assess your roofline. Look for any noticeable dips or unevenness in the roof’s surface.


Contact a professional roofing contractor to inspect and assess the structural integrity of your roof. They will recommend the necessary repairs or replacements.

Shingle Blistering

Shingle blistering occurs when moisture becomes trapped within the shingles, causing them to bubble or blister. It’s more common in asphalt shingles.

🔍 Identification

Inspect your shingles for small bubbles or blisters. These can often be seen on sunny days when the shingles heat up.


While blistering isn’t typically a major issue, if the blisters become too large or frequent, it may be best to replace the affected shingles.

Clogged Gutters and Downspouts

Clogged gutters and downspouts can lead to water backing up onto your roof and causing damage to shingles and the roof structure.

🔍 Identification

Check your gutters for leaves, debris, or granules from shingles. Look for signs of overflowing or leaking gutters during rain.


Regularly clean your gutters and downspouts to ensure proper water drainage. Consider installing gutter guards to prevent debris buildup.
