Question 1

Do algae-resistant shingles prevent moss?

Accepted Answer

•

Yes, algae-resistant shingles will prevent algae and moss growth, providing double protection for your roof and roof flashing. The copper-infused granules on algae-resistant shingles release copper ions that inhibit plant growth in general, so moss will have a harder time growing on your roof, too. Keep in mind that copper ions flowing off your roof during rainfall can also inhibit plant growth below, so your gardens and grass may be affected.

Question 2

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 3

What time of year is best for roof cleaning?

Accepted Answer

•

The best time of year for roof cleaning depends on the climate in your area, but in most cases late spring or early summer are the best times. You should plan to clean your roof when it’s dry and not too hot or cold. It’s also a good idea to clean your roof in the late autumn to remove any built-up debris like leaves or branches. On the other hand, you shouldn’t clean your roof when it’s too cold, because you can cause ice buildup.

Question 4

How long does it take to clean a roof?

Accepted Answer

•

On average, cleaning a roof will take between two to five hours. This timeline depends on the size and slope of your roof and the severity of any stains. Cleaning roof stains can take additional time, especially if there are signs of moss or algae.

In addition, the age of your roof makes an enormous difference in the time it takes to clean it, as older roofs need more gentle care. If you have significant landscaping in your yard by your house, your professional roof cleaner will need additional time to protect it from cleaning chemicals.

Question 5

Do heated roof cables prevent ice damming?

Accepted Answer

•

Yes, and they do it exceptionally well. Heated roof cables have two purposes: melting snow and preventing ice buildup. Ice damming happens when ice forms on the roof (usually where the roof meets the gutter) and melts stubbornly slowly, causing moisture to enter the roof itself and, therefore, the home.
