Cleaning your roof is an important part of owning a home. Your roof is a major structure which protects your home and family from the elements. If you don’t take care of it by regularly clearing off debris and keeping up with professional cleaning, mold, moss, algae, and more can grow and cause extensive damage. When it comes to roof maintenance, knowing what type of roof you have is crucial. Different types of roofs should be cared for and washed clean in different ways.
Asphalt shingles are very common in the United States because they are easier to maintain and work in all different environments. They do not generally take any special care besides general washing and clearing, though pressure washing may damage them.
Clay or Concrete Tiles
Clay and concrete tiles are more fragile and prone to cracking under pressure. If using pressure washing or strong chemicals, outer layers may wear down and need to be repainted and then resealed to keep debris and harmful growth from getting in. They work better in warm, dry areas.
Slate is an effective material in wet areas because it is resistant to water and growth of mold and other materials which can cause damage. It is more easily breakable and should not be exposed to pressure or certain harsh weather conditions like hail.
Wood Shakes and Shingles
Wood shakes and shingles are more likely to hold moisture and grow moss and other similar materials, so need to be checked and cleared of debris with more regularity. If the wood is made from cedar, it especially needs to be kept clean from any debris. Cedar roofs need to have space for air to flow around them, so nearby trees should be kept trimmed back.
Metal roofs are strong but lightweight, resistant to fire and water, and heavy snowfall falls off it more easily. It can rust or corrode over time and can dent when hit with hail, tree branches, or other large debris. Be careful with cleaning materials as certain types may cause corrosion.
If you are unsure what type of roof you have or the best way to care for it, contact a professional roof washer who can guide you on the best care and prevention methods for your type and the environment in which you live.
