Brick walls are very sound insulating, excluding noise from your house and other properties. They are also watertight which prevents moisture penetration, which can in turn cause wall damage from freezing/thawing. Colours of the roof will need to match brickwork for a nice finished look. Study their main cast colors and sub-tones so you can pick roofing colors that are seamless with them. Weep Holes It’s a practice of brick masons to make weep holes in the brick wall, deliberately to avoid water damage, and move the water away from it while giving it more air circulation, so less moisture causes mildew and mould. Weep holes also avoid structural issues, as by retaining moisture in the wall cavity, water doesn’t build up behind bricks and cause spalling bricks and subsequent masonry problems. Without weep holes, water might be able to gather behind them and collect behind bricks which can result in spalling of bricks or worse structural degradation of masonry construction. Weep holes can be between bricks, or plastic tubes that go at regular intervals into wall cavities to circulate air. They should be paved with mortar so they don’t clog, and an optional wall around them should keep out termites, rodents or sparks. : Some homeowners attempt to fill in these spaces with caulk or mortar, which would close up the weep holes and allow moisture to get trapped in them, creating moisture accumulation with no drainage system. So you must regularly clean and check weep holes to keep them free of dirt and mud and allow water to flow freely from your house. Flashing Flashing: This is a sheet of metal that is used to secure the wall assembly, redirecting moisture from going through walls or sheathing and into roof shingle panels or into interior of substrate. Installed anywhere walls/sheathing have an opening it should generally be made of copper, aluminum or galvanized steel strip products and some kind of membrane to seal off the leaks. Probably the most common complaint we hear is water getting into brick or masonry veneer where roof eaves, gables, chimneys and windows come together. Too many masons forget that no single layer of brick can guard against this type of attack. Through-wall flashing, though it is the only way to insure a building when this happens, takes more time, planning and work than simple step flashing installations. You can also use counter flashing in mortar joints where no fill has been applied to stop moisture. In addition, through-wall flashing should be capped off with cap flashing that extends four inches at a time on either side and three inches across on the back side to prevent water from leaking. Waterproofing It takes waterproofing products to keep structures afloat. When you don’t waterproof a building, it might be durable in the long run but damaged at various locations. Waterproofing can also keep fungi and molds from growing, preserve electrical circuits and decrease health risks, and increase energy efficiency through insulation that reduces heat loss. It is the brickbat coba method that is the most used waterproofing process that involves the brickbats and cement mortar for creating a waterproof membrane on roofs and terraces. Cheap and easy to install, brickbat coba also loads up roofs with heavy materials that might pose a risk for structures with smaller load-bearing capacities. Waterproofing with liquid membranes is another common type that comes in several models and thicknesses like SBS modified bitumen or PE (polyethylene). They’re also torch-safe, flexible enough for concrete roofs, wood and metal – handy for strange-shaped roofs!
