Moss Removal Maintenance...
Moss, Algae and Lichen Removal Program
There is no need to undertake potentially damaging and dangerous procedures like pressure washing or painting. All this will do is invalidate the manufacturers warranty. This will mean that your home insurance will no longer cover the cost of repairs or maintenance.
Firstly it is important to know what type of roof you have, C. Stevens Roofing is concentrating on concrete tile roofs.
The most effective way of removing clumpy moss is to brush it off on a dry day. After the moss has been removed the roof can be treated to kill the moss spores and prevent new growth.
About Concrete Tiles
Concrete tiles are available in many colours and styles. They can even be made to look like slate or clay tiles. The concrete tiles interlock with each other and are laid over wood laths (strips). Most of them will not be nailed down but rely on their weight and interlocking design to hold them in position.
It should be noted that concrete tiles are not made to be waterproof but instead to shed or disperse the water. This is why it is important to keep concrete tile roofs free from debris and any matter that absorbs or holds moisture. It is especially important to keep the valleys clear where the water should flow away and off the roof. If water is allowed to collect it can fill up the gutters or valleys and get into the insulation or wood beneath the tiles.
Since concrete tiles are on the roof the roof structure must be built to withstand the weight of the tiles. For this reason concrete tiles are made porous to keep their weight down. This is a good and bad thing. Good as it is easier to transport, handle and support on the roof. Bad because the tile holds sufficient water to support moss.
When new concrete tiles have a finish glaze on their surface. The glaze repels water but over time UV sunlight breaks down the glazing. This leads to micro fractures and the ability for the tile to hold water. This water wicking effect feeds moss spores that collect on the bottom edges and interlocking edges of tiles.
