Roof Facts, The Truth Revealed - The Exterior Company


When it comes to protecting your home, it’s what’s on top that actually matters. Common misconceptions about roofing can contribute to a false sense of security.

Below you will discover the top 10 myths about roofing.

Myth: All homes in the neighborhood are affected the same by hail.
Fact: Not all homes are affected the same way. The size and hardness of a hailstone can vary in a small area. Other factors include the pitch of your roof, its age and condition.

Myth: Lighter color “splatter” marks on your roof after a hailstorm means there has been damage done.
Fact: No, splatter marks do not necessarily mean any damage has been done. Splatter marks are normal after a hailstorm. Over time, your roof darkens due to algae and oxidation. When hailstones hit your roof, they remove the algae and oxidation that have formed, leaving a light colored mark. With time, the marks will fade as algae grows and oxidation continues.

Myth: I don’t see any damage to my roof after a major hailstorm so I can just ignore it.
Fact: Even if you cannot see any damage to your roof, there still may be significant damage under the shingles. That is why after any major hailstorm, it is important to call an experienced roofing professional.

Myth: I do not have to remove ice that has collected on the edge of my roof.
Fact: Failure to remove the ice can cause snow buildup, which can later melt and cause leaks in your roof and force water to back up under your shingles causing them to lift.

Myth: Metal roofs increase your chances of a lightning strike.
Fact: Lightning is not attracted to metal and usually hits elevated objects such as trees, towers and telephone poles.

Myth: I can power wash my roof.
Fact: Power washing can harm your roof. High pressure can force water under your shingles, which can result in mold and mildew growth.

Myth: Flashing only needs to be replaced when a new roof is installed.
Fact: Flashing should be checked every 6 months. Look for cracked or broken flashing pieces and damaged shingles in contact with flashing. If you notice any damage, have a roofing contractor inspect the area.

Myth: My roof is new so I have nothing to worry about.
Fact: New or not, your roof is still susceptible to hazards. For a complete list of potential hazards, check out our blog “What causes damage to your roof”.

Myth: Roof maintenance is a waste of money.
Fact: Lack of proper maintenance can result in a shorter life span and costly repairs. Proper maintenance involves through inspection and minor repairs when necessary.

Myth: You can cover old shingles with new shingles.
Fact: Underneath your shingles is a layer called sheathing that is usually made of plywood. This layer can rot from leaks, inadequate ventilation or old age. The only way to check the sheathing is to tear away the old shingles.
