Examining your roof regularly reduces the risk of irreversible damage and highlights issues that should be attended to before they develop complications, potentially saving on major repair costs. Furthermore, a well-maintained roof adds to the overall aesthetics and the house’s market value.

The accumulation of dirt or debris like fallen leaves and broken tree branches on your roof creates a favorable environment for moss and lichen to thrive, building up moisture that is damaging to your roof.

Periodic Roof Examinations

A fundamental procedure in roof maintenance is to do a check for any obvious damage or fault in the structure and moisture-trapping hazards that promote rotting. On top of the recommended biannual inspections, homeowners should also check their roofs after a big storm or extreme weather conditions.

Signs of wear and tear that you should look out for:

  • Presence of algae, moss, or lichen
  • Defected, missing, or cracked shingles
  • Damaged caulking
  • Rusty flashing
  • Visible cracks on vent boots
  • Accumulation of asphalt in the gutters

Depending on the type of roof, it may or may not be a practical idea for you to personally handle the maintenance check. Some roofs with a steep gradient and fragile shingles can be easily damaged from uneven weight distribution. Hence, it is best to avoid walking directly on it. In addition, when using a ladder on this particular type of roof, align the ladder’s pitch to the roof to allow a fair distribution of weight, reducing the risk of any unintentional damage. 

If it’s difficult to carry out a detailed examination of the roof on a regular basis, homeowners could simply use a pair of binoculars to do a quick visual scan. Alternatively, you could hire a professional roof inspector to do the job too.

Periodic Roof Cleansing 

Pits and depressions in the structure inevitably tend to collect dirt and debris. Begin the cleaning process by removing anything that may have gotten trapped in the gutters, valleys, snow guards, and the zone behind the chimney. Wear protective gloves to clear the litter that is within reach. Use the help of a broom or a leaf rake for areas that are difficult to reach.

Proceed to spray the roof with a 50-50 mixture of bleach and water solution to rid the algae, moss, and mold, if any, on your roof. Finally, keep the landscape tidy by trimming any overhanging tree branches to minimize the accumulation of fallen leaves and twigs. 

Cleaning Tips for Various Types of Roofs

Asphalt Shingles

The most popular choice among homeowners in the United States, asphalt shingle roofs are commonly known for their low-upkeep demands. While the basic steps to maintaining your roof should suffice for a typical asphalt roof, avoid using washing it with high-pressure water sprays as it might break or crack the shingles. Further, try not to use strong chemical products such as bleach as it would cause discoloration of the shingles.

If you spot fragments of asphalt shingles accumulating in the gutters, take note that it could possibly be a sign that it’s time to replace your roof.

Clay and Concrete Tile

As with asphalt shingles, avoid using harsh chemicals and high-pressure water sprays on clay or concrete tiles as they will destroy the tile coatings and paint which helps to deter the growth of moss on the roof. Moreover, tiles are very brittle and can break under high pressure.

Unless necessary, do not step onto the tile roof. In the case that you are required to do so, use a plank of plywood with a foam treatment underneath to help with even weight distribution, relieving the stress placed on the tiles.

Although the presence of efflorescence on the tiles is not damaging, it makes the tiles look washed out. This can be dealt with by buffing the roof using a dry cloth when the roof is no longer wet.

Wood Shakes and Shingles

Water jet sprays can lift wood shakes and shingles, trapping water beneath them and resulting in a leaking roof. The use of bleach should be avoided as it causes discoloration. On top of that, any access liquid runoff from the rooftop could kill the plants in your garden.

Any sighting of moss and lichen should be immediately dealt with because they could potentially void the warranty of your roof. One preventive measure for the growth of moss is to manage your landscape, especially by cutting tree branches hanging directly above your roof.

Cedar Shakes and Shingles

If trimming the overhanging tree branches were important to roofs in general, it is especially crucial for the cedar shakes and shingles because they require a clean environment to breathe. As ventilation is vital for the maintenance of cedar roofs, ensure that gutters and downspouts are clear as often as possible.

Avoid the use of high-pressure water sprays except in extreme cases of serious moss infestation in which should only be handled by a roofing expert. Bleach and ammonia shorten the lifespan of cedar shakes and will cause discoloration to the roof.

Slate Shingles

When exposed to moss and debris, the accumulation of moisture can deal enough damage to the slate shingles that they could split during winter. Considering that slate shingles are pricey and fragile, do not use pressure sprays and avoid using ammonia and bleach on them.


Metals have chemical reactions when in contact with other metals and so it is best to keep them away from one another, lest they damage the roof. Take precaution in keeping your metal roof clean by using products that are suitable for the particular type of metal of your roof.


Roof maintenance is made easier with this guideline focusing on specific types of roofs. Even though cleaning your roof may seem like a tedious job, it’s not that difficult when you set your mind to do it, especially now that you are made aware of the special needs of your roofing material!
