What are ice dams and how can they damage your roof?

What is an ice dam?
A ridge of ice that forms at the edge of a roof and prevents melting snow from draining off the roof.

What causes an ice dam?
Ice dams form when indoor heating rises through the ceiling into the attic and warms the roof surface.

How do they form?
Snow on the heated part of the roof melts and flows down until it meets the part of the roof that is below 32 degrees. At that point, the water freezes into an ice dam.

How do ice dams lead to water damage?
Water backs up behind the dam and, as it sits on the roof, works its way under the roof covering and flows into the attic. From there it can seep through insulation, ceilings, walls and other areas where it can cause damage.

How do you prevent an ice dam?
Keeping a consistent attic temperature can help prevent ice dams. Insulation and ventilation are key components of maintaining the proper conditions in the attic and on the roof deck.

Do you need a new roof?

Shown below are common symptoms that indicate it may be time for you to get a new roof. Select your roof style and click on any problem to learn what’s causing it and how to fix it.

New shingled roofs should last upwards of 20+ years. However, many factors, such as proper installation, climate, and ventilation, impact the life of your roof.

Even if your roof shows signs of the symptoms mentioned above, you may not need a total roof replacement. A trusted roofing professional can give your roof a thorough examination and let you know if you are in need of a new roof, or just a few repairs.

1. Algae Growth: Algae growth causes a dark discoloration on roofs. The algae is usually brown to black in color which results in a streaked, dirty looking rooftop. Algae is mistaken for soot, dirt or tree droppings, which typically produce only localized discoloration. Algae is caused by the growth of air-borne algae which deposits on your roof. The good news is that algae growth does not affect the service life of your roofing material. It occurs most often in warm, humid climates such as the Southeast (where algae-resistant shingles are available).

2. Damaged Flashing: Causes include – Improper installation on a new roof, drying and cracking on an old roof, dented by improper nailing, or settling of the structure

3. Buckling: Causes include – Improperly applied felt, wrinkled underlayment, roof deck movement, spacers not used in between roof deck boards, poor roof ventilation, or new shingles applied over old, rough shingles

4. Curling: Causes include – High nails, lack of back coating, under-saturation of asphalt felt in organic shingles, lack of ventilation, or improper number of fasteners

5. Blistering: Causes include – Moisture in the shingle

6. Missing Shingles: Causes include – Improper fastening or exposure to high winds

7. Ceiling Spots: Causes include – Spots are caused by leaks in the roof

8. Missing Granules: Normally a certain number of granules will be loose, especially after application. These granules are called “riders” and are a normal result of the manufacturing process. Granule loss does not affect the service life of the shingles unless granules can be seen missing on the surface of the shingles, thus exposing the asphalt or Fiberglas ® mat.

9. Rotting: Rotting is caused by absorption of moisture by the mat at the core of the shingle. This is a common problem with organic-based shingles.
