Question 1

What kills moss permanently?

Accepted Answer

•

Chemical herbicides will kill moss permanently. The same goes with bleach water. However, moss can start growing again once a new layer of dirt and debris is caught in your sand in paver joints. Therefore, the problem is not about killing moss permanently, but ensuring effective prevention of moss regrowth.

Question 2

Do you need to clear snow from the roof?

Accepted Answer

•

While removing every snowflake from your roof is unnecessary, you should remove a significant buildup of snow. Since snow is wet and heavy, it can easily cause damage to your roof, which can lead to needing costly repairs.

Additionally, when the snow melts but has nowhere to go and refreezes, it can create an ice dam, causing mold concerns due to water leaking into your attic and ceiling. For these reasons, it’s best to hire a snow removal professional to clear heavy snowfall from your roof as soon as possible.

Question 3

Should I clean my roof shingles if the roof has physical damage on it?

Accepted Answer

•

You should not clean roof shingles if the roof has damage like missing shingles or low spots where water may accumulate. You should focus on repairing the roof before any cleaning process occurs. If you notice roof damage as you’re climbing on the roof to clean it, stop immediately. Call a roofing pro to make repairs. Cleaning a roof that has damage could lead to pooling water or water damage to the roof decking. The roof cleaning process removes mold and mildew, making the roof look better. It is not going to fix physical damage, though.

Question 4

Do roof rakes cause ice dams?

Accepted Answer

•

Roof raking helps clear snowfall from your roof and, in turn, you hope that this prevents ice dams. But can roof raking actually cause them? Generally, no, it cannot. But you should note that while, in some cases, you might successfully prevent ice dams from forming near the edge of your roof by keeping it cleared with a roof rake, they could still form higher up on the roof, where you are unable to reach. This may leave you wondering: Does roof raking prevent ice dams? While it is not a 100% guaranteed way to prevent them, it does help.

Question 5

If you’re asking yourself, should you pressure wash your roof, the answer almost always is no. The water pressure that the power washing machine generates could damage the shingles by forcing water underneath or causing them to loosen. Soft washing with a pump sprayer is the better and safer option.
