Additional Maintenance Necessary for Tile Roofs

When you have your tile roof cleaned you may want to consider taking some extra steps which can prevent a very tragic outcome. Often moss, dirt, pine needles, or whatever else it may be, start to build up underneath the tiles along the walls and in the valleys. As you can see in the photo to the left, there is a piece of metal, normally under the tiles, which runs along the wall and catches any water that runs along there, draining into the gutter.

When debris starts to build up under the tiles the water caught by the wall metal starts to dam up and can eventually spill out over the side causing a leak. This is the reason that, as you can see to the right, we pulled back the tiles from the wall so that we could clean out all of the debris trapped in that crucial area.

To the right is a picture showing what can happen when debris builds up in a valley. As with the wall, there is also metal running underneath the tiles where two sections of the roof meet each other in a valley. Again debris can build up and create a dam causing a leak. as you can see here the felt paper underneath the tiles was decayed as a result of the debris and water accumulation. In this same valley, there were other places where the trail of decay reached beyond the valley metal and onto bare wood which was without question creating a leak. This family did not know about the leak until the sheetrock fell from their dining room ceiling. Practical Pressure can provide a cleaning service involving the removal and replacement of tiles from valleys and walls so that debris can be cleaned out from underneath these crucial areas.

Below is a picture showing just how much debris can get caught underneath your valley. As pine needles are carried down the valley by rainwater they catch on the tile corners and before long they accumulate and can reach excessive levels as was the case here. You can see that the wood in this picture is already rotting. All that debris will soak up and siphon water sideways underneath the tiles and things will stay wet for long periods leading to rotting, mildew, mold, and other problems. The tiles must be removed to effectively clean out all of the buildups.
