"Would give 0 stats if I could! Stay away from Tim. Quoted us for a fence with 2 gates as we wanted, showed up a week later with only one because he forgot. Due to supply shortage he couldn't get another one and the one he had was cracked anyway. So here we are October when the fence was done in May, being ghosted when all we want is the money for the gates and labor costs refunded. Tried to give them the benefit of the doubt but now not being answered is the last straw."

Roof Cleaning questions, answered by experts

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.

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. 

An improper DIY roof cleaning could cause leaks by damaging the roofing material. Things like using too much water pressure on the shingles or applying a harsh cleaning solution could cause damage. If you do enough damage, you could harm the ability of the shingles or other roof materials to keep water out of your home.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.

You may become so frustrated with the look of moss on your roof that you contemplate whether to clean or replace your roof. Fortunately, you don’t have to go as far as replacing it. After cleaning the moss, you can use a chemical solution to keep it away. For further protection, trim branches that overhang the roof, as fallen seed pods and leaves on the roof allow moisture to collect, encouraging moss growth. Consider adding zinc-coated flashing to the roof, too. As rain washes across the zinc, it leaves zinc particles behind that inhibit moss growth.
