Are you sure it’s moss? Mosses are fairly thick plants that prevent water from flowing normally and promote infiltration. The green-to-grey colouring of the tiles can be explained more often by the presence of algae or lichens. The proliferation of these undesirable substances depends on climate, prevailing winds and even pollution in the air. Little compact snow can detach them naturally. Another solution, less random is annual maintenance which consists of spraying a suitable product, the least toxic possible.
After repair, what to do to protect the roof?
Inspect it regularly and intervene quickly. Do the daily roof investigation with Toronto Roofing Contractor to see if there is any spot left that needs the quick repair, tiles slotted or loose attics, damaged weathervane, flickering antenna, fouled gutters, green tree branches or climbing plants, weakened chimney, etc. Check ridges, hips and especially mortar seals because of the risk of infiltration. The ventilation of the roof must also be done in the right conditions.
Do you have the choice of the roof?
Before going around the suppliers, it is better to know what the local rules on roofing are and what will be your leeway to choose your model. Contact the town hall to find the prescriptions of the regional urban plan. If you have the chance to do as you please and enjoy the contemporary style, the terracotta tile offers a wide range of shapes and forms. Modern trends are plain colours and black, grey shades close to slate.
If the tiles break, how do you do it?
Beware of tiles that are too original or come from countries that you do not know if the supply will be guaranteed in time. Exotic tiles may be tempting, but you do not always think about the problems of after-sales service. In case of a storm, it will take a long time before being delivered unless you have a substantial reserve of tiles. Beware of too attractive prices. Get professional advice. Consider the cost of maintenance. Also, think about the durability of the insulation. If the tile is not sufficiently waterproof or resistant or does not respond correctly to the indications of the local authority, you risk the disaster. Finally, think about the durability of colours.
Conclusion: And the form?
Large formats will generally allow you to lower the cost per square meter. Then there are three main types of tiles, flat, interlocking tiles and channels. The plates are suitable for steep slopes, and their number per square meter is quite high. They are overlapping and require a high degree of accuracy from the roofer to prevent slippage. Larger interlocking tiles are faster to install. The interlocking principle prevents slippage. There are quite economical large mould sizes and very elegant small mould sizes. Make sure your pipes are secure. Choosing the best materials is not the specific solution all the time but to determine the best roof repairing or maintenance contractor is the ultimate choice that you should opt.
