A hipped roof has four sides that slope towards the eaves and is used in architecture worldwide. It creates a uniform, solid look and requires less support. Variations include the mansard roof and dormers. Hipped roofs resist high winds well, making them popular in hurricane and winter storm-prone areas. A hipped roof is a style […]
Roof construction is crucial for protecting buildings from the elements. Design factors include roofing materials, construction process, and suitability for the application and local weather conditions. Local conditions also affect roof construction, with sloping roofs for snow and low, wide roofs for wind. Durability, aesthetics, and cost are also important considerations. In the process of […]
Concrete installers use steel bars for structural support in reinforced concrete. The distance between the top of the rebar and the top of the finished concrete, or concrete cover, is important for durability and performance. The amount of concrete cover required varies based on factors such as seismic activity, weather conditions, and structure type. Local […]
Roof hoists lift heavy roofing materials onto a building’s roof safely and quickly. The ladder hoist is the most common and uses a metal ladder and a hand crank or motorized hoist system. The swing beam hoist is suitable for larger buildings and can lift heavier loads to greater heights, but can be difficult to […]
The Roof of the World in Central Asia is a high elevation region with unique cultures and Mount Everest. It was formed by India’s collision with Asia, and includes Tibet, India, China, Pakistan, and Tajikistan. The harsh environment made it unattractive to colonize, but it became valuable for tactical reasons in the 20th century. The […]
Roofing mastic is a product used to seal roofs to prevent water penetration. It comes in different types and can be applied with putty knives or caulking guns. It can extend the life of a roof and is flexible to withstand weather conditions. It can also be tinted for energy efficiency and is given a […]
Roof beams support a roof and can be made of wood, steel, aluminum, or composite materials. Steel is used in larger structures, while wood is cheaper but prone to damage. Composite beams are lightweight and less prone to damage but not designed for heavy loads. A roof beam is generally a length of wood, steel […]
Roof joists support the roof and distribute its weight evenly. They can be made from various materials and attach to rafters. Engineers consider factors like snow accumulation and changes in roofing materials when designing joist placement. Joists can limit headspace, but custom variations can be designed. They vary in size and should not be cut […]
Roof cladding provides weather protection and aesthetic appeal. Common options include asphalt or slate shingles, ceramic or concrete tile, and sheet metal. Shingles are thin, flat squares or rectangles of material applied in an overlapping fashion. Asphalt shingles are affordable, while slate shingles are long-lasting but expensive. Ceramic tiles are long-lasting and attractive, while concrete […]
Shell roofs are curved roofs used to cover large one-story buildings, commonly found in public buildings. There are three types: single barrel, multi-barrel, and continuous barrel. They offer extra structural support, are aesthetically pleasing, and rarely leak, but are expensive to build and have issues with lighting and ventilation. However, they can save money on […]
Roof edge protection is essential for worker safety during construction and renovation projects. Different types of protection, such as railings, scaffolding, and screens, are available to meet safety standards set by government authorities. The type of protection needed depends on the type of work being done and the roof style. Safety equipment vendors offer a […]
Roof ventilation comes in various forms including turbine vents, low profile vents, and ridge vents. It lowers the temperature and removes moisture from the attic, helping roofing materials last longer. Solar powered vents and skylights are also available. Different types of vents suit different roofing types and design choices. Roof ventilation, also known as attic […]
Roof pitch affects roofing prices and safety, with slopes over 15 degrees considered steep. Steeper roofs have advantages, such as longer-lasting tiles and better water repelling. Flat roofs are unsuitable for wet climates. Knowing roof pitch helps with repairs, but it’s safer to hire a professional. Whether you’re buying a home or repairing your existing […]
Standing seam roofing is made of metal panels held in place by clips and a thin metal cover to prevent water from passing between panels. It is durable, easy to install, and comes in many colors. It is also resistant to wind and ice. Modern panels are made from high-quality materials and can last for […]
Shed roofs can be built in various styles, with advantages and disadvantages to each. The hipped roof is the simplest and provides more usable space, while the gable roof may not have much space underneath. Roofing materials can match existing structures, and weather conditions should be considered. Proper installation and maintenance are important for the […]
Reflective roofing coatings reduce solar heat and cooling costs, extend roof life by up to 15 years, and block UV rays. High albedo products are the most effective, and the Cool Roof Rating Council provides Energy Star labels to quality products. Costs range from $0.75 to over $3 per square foot. Reflective roofing coatings, also […]
Slate roofs are made of highly resistant metamorphic rock and are suitable for roofing. They are more common in regions where slate is abundant, but can be shipped elsewhere. Slate is durable, water-resistant, and adds value to a home, but is heavy and expensive. Expert installation is necessary, and regular maintenance is recommended. Professional organizations […]
Roof access can be achieved through stairs and doors or trap doors and windows. Attic access is sometimes included but usually closed off. Access is required in larger structures for safety reasons. Ventilation and light can also be achieved through roof hatches and mechanized roof openings. Attic stairs are another type of access. Local regulations […]
Cold roofs prevent ice damming and structural damage caused by moisture seeping through the roof. Traditional cold roofs have a well-ventilated attic, while unventilated cold roofs use a breathable polypropylene membrane. Both reduce winter humidity and keep the building cool in warmer weather. With a cold roof, the roof temperature stays the same as the […]
Roof inspectors examine and report on the condition and life expectancy of a building’s roof. Licensing and certification are often required, and training covers materials, building codes, and structural damage. Inspections are requested by owners, buyers, insurance companies, and lenders. Inspectors may also offer repairs and charge a fee for their services. A roof inspector […]
