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

What time of year do you remove algae from a roof?

Accepted Answer

•

Ideally, you will tackle removing algae from your roof during spring or summer when the weather is drier and warmer. Because algae tends to grow during the colder and wetter months, you want to tackle this project before the temperature drops to hopefully keep it from coming back at all.

Question 3

Should you use a pressure washer on the roof shingles?

Accepted Answer

•

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.

Question 4

Is it worth having your roof cleaned?

Accepted Answer

•

Having your roof cleaned can be worth it because it improves the life span of the materials on the roof. You won’t have to pay a roof replacement cost as often when you clean the roof regularly.

Question 5

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.
