Concrete Tile Roof Maintenance Instructions Concrete Tile Roof Maintenance Instructions

Concrete tile roof is not only a cost-effective roofing solution but also a very durable and sophisticated roofing system. Moreover, its maintenance is minimal and is generally limited to gutters, venting and protrusion flashing. There are very simple things to look out for—moss and dirt build-up are amongst the most common. However, while concrete tiles are designed to be long lasting, their maintenance is of utmost importance to avoid major problems such as leaking roofs. Even more so, their upkeep also helps preserving the coloring of the tiles themselves which is a very important factor since concrete tile roofing is decoratively appealing.

Cleaning of Concrete Tile Roof

Depending on climate conditions and weathering factors, concrete tile roofs generally vary in durability from 30 to 70 years. Its most common issue is moss and lichen growth. Both are attracted by moisture and thus should be removed, not only for protecting the tiles themselves but also for aesthetic reasons. Any overhanging trees should be cut and the roof should be washed with water and bleach solution which is available from hardware stores (do not add the bleaching solution if you collect rain water for drinking purposes).

The easiest way to do this is by using pressure water (avoid water blasters—they might force water beneath the tiles causing greater damage than the moss itself). Water should be directed from the highest peak of the roof from a distance of 3 to 4 feet of the area you are washing and in the direction of the roof’s drainage system. Use safety harnesses and goggles for your own personal protection. Generally pressure washers have the concrete-rating nozzle, which is the best pressure you would like to use, however even the 3,000 PSI-Rated nozzles are good. Wash the roof evenly at least twice.

Dislodged, Damaged or Missing Tiles

Although concrete tiles are long lasting, even if properly installed they may get dislodged. Climate, weathering and erosion can cause tiles to break, but this can also be caused by simple walking on top of them. It is important to keep a watchful eye and step very carefully on the tiles. It is essential to replace any missing or damaged tiles to avoid the problem from spreading.

If a tile is damaged you may need to use a crowbar. Slide the crowbar beneath the tile to the left side of the one which needs replacement and carefully apply downward pressure to force the tile upwards till it no longer rests on the damaged tile. Repeat the same process for the one on top. The new tile should be easily installed. Nowadays tiles may be snapped directly into place but if this isn’t the case use nails to nail it down. You may consider using roof adhesive but nails are more secure.

These are two of the easiest ways to keep your concrete tile roof in good order. The major problems are moss growth and damaged or dislodged tiles which have easy solutions to them. Concrete tile roof maintenance is a task easy to handle which only requires a watchful eye from the homeowner and some on-going repairs and cleaning.
