It’s safe to say that its impossible to control all variables, but you can fight them and win with preventative maintenance services or long term protection.

Black staining is caused by the growth of algae and fungus spores that land on your roof, (Staining is not caused by pollution, soot or jet exhaust). These spores need three things to grow: heat, moisture and some kind of nutrient. The nutrient comes from dirt and the shingle itself, primarily the limestone filler used in manufacturing the granules. Shingle roofs are manufactured with different degrees of quality. Pricing is one way to tell the quality of a roof and the manufacturer warranty is another. Most roofs applied by builders and roofing contractors are in the low to medium quality range. Higher quality roofs are generally found on expensive custom homes and where the owner has taken a special interest in the quality of the roof.

Clay tile roofs are fragile and caution should be taken when walking on these roofs. Wood shingle roofs will require the least amount of pressure at about 1000 PSI or less. When pressure washing any roof use caution around flashing. Never pressure wash at an angle that will allow water to flow up the roof and under the shingles. Bleach should not be used on shingle or wood roofs as it will cause damage. You never want to try to pressure wash from a ladder. The pressure from the wand can knock you off balance.

To protect your roof from early replacement, annual pressure washing is recommended. You will want use between 1000-1800PSI depending on your roof material. Metal roofs are becoming more popular because of price and the length of time it lasts, a higher pressure may be used on these type roofs. You should always contact the roofing material manufacturer to find out recommended pressures for their product. You may want to try an extension wand for those hard to reach places.

A note of caution: Cleaning your roof by yourself can be hazardous. Roofs over a 7/12 pitch are not walkable, even for trained professionals. A roof is not going to clean itself nor is it only going to take five minutes. Cleaning a roof is a project that is going to take some time and effort and a few trips up and down the ladder.
