A roof is an important part of a building that protects against rain, snow, sunlight, and wind. Depending on climate conditions and architectural styles, it can be made of shingles, asphalt sheets, or other materials.
A roof’s peak is called a ridge; its sloped edges are eaves. The area where two roof slopes meet is a valley.
Various roofing materials are available. The one that works best for you depends on several factors, including your budget and the climate where you live. A professional can help you decide what kind of roof will be most durable and attractive for your home.
Wood shingles and shakes are popular because they add beauty to a home. However, they are expensive and not as long-lived as other roofing materials. They are also not a good choice for areas that experience frequent wildfires.
Asphalt shingles are a common roofing material, and they come in many different styles to fit any home. Some even mimic the look of other types of roofing materials, like slate and cedar shakes. The color of the shingle and its thickness will affect how long it will last.
Metal is another good option for flat or low-slope roofs. Corrugated galvanized iron (called “Gal Iron” in Australia) was a common roofing material during the 20th century and is still used for sheds and other small buildings. More recently, galvanized steel has been replaced by newer materials with longer lifespans.
Rubber roofing is a sustainable material that can be made to mimic the look of other roofing materials, such as slate and wood. It is also fire-resistant, but it can have a distinctive odor and does not insulate as well as other roofing materials.
Slate is a luxurious roofing material that adds an elegant touch to any home. It is typically found on older homes or high-end new constructions that seek to preserve the historical look of a building. However, synthetic slate can be used to achieve a similar appearance at a much lower cost and weight.
Rolls of tin or lead are not commonly used for residential roofing, but they may be necessary for some commercial applications. Lead is especially effective for low-slope roofs because it helps them resist moisture. It also has the advantage of being able to be bent easily to accommodate pipes and vents.
Installation
The roof is the uppermost layer of a building or structure. It protects against rain, snow, sunlight, and wind. It can be made of a variety of materials like asphalt shingles, metal sheets, clay tiles, wood shakes, and slate. Depending on climate conditions and architectural style, the roof may be flat, pitched, vaulted, or domed. The construction and maintenance of the roof is vital to the structure’s integrity, comfort of occupants, and preservation of property.
Before starting any roofing project, a contractor must make sure that the proper permits are in place. This includes obtaining any homeowner association or architectural review board approval if necessary. It is also important for the contractor to ensure that they have all the necessary equipment and supplies, including ladders, tools, tarps, and generators.
Once the crew is set up and ready to start, they will remove the existing roof covering and begin installing new materials. This can create a lot of mess, so the crew will take steps to protect your property. They will cover landscaping and shrubs with tarps to prevent any debris from falling on them. They will also cover any open drains to prevent small pieces of roof from blocking them.
Shingles are installed in courses or layers, and each course is overlapped with the one below it to provide a watertight seal. The next course is then nailed to the sheathing with a nail gun. This process is repeated until the entire roof is covered with shingle. To improve the look of a roof, some contractors will add vents to help with attic ventilation and vapor retarders to reduce condensation.
Most of the work on a roof is repetitive and physically demanding. It is important to protect yourself and your employees by following best safety practices. Having a multi-layered approach to fall prevention and protection, including training, toolbox talks, and the use of safety harnesses can help decrease accidents and injuries. Resources to help in implementing these safety measures include the Construction Fatality Assessment and Control Evaluation (FACE) database, ladder safety mobile application, infographics and tipsheets, toolbox talks, videos, and webinars.
Managing a roofing business includes scheduling jobs, negotiating deals and ordering supplies. Owners also need to choose and maintain roofing tools, decide whether to rent or buy equipment and deal with accounting issues, like payroll, taxes, sales tax and insurance.
Roofers spend most of their workdays on the job site, performing repetitive and physically demanding labor. They unfurl layers of underlayment and nail new shingles to the roof, using a nail gun for speed. They may also add flashing around chimneys, wood stove pipes, dormers and roof valleys, and apply roofing caulk to raw edges.
Roofers must also protect the property around their work area with tarps and cover open drains to prevent clogging. Other duties include cleaning up and disposing of debris, and meeting with customers to discuss their finished roof.
Maintenance
The roof isn’t a one-and-done project; it requires ongoing maintenance to keep water leaks at bay and extend the life of the materials. Routine maintenance includes trimming trees so they don’t overhang the roof, ensuring that flashing around chimneys and vent pipes is in good condition and replacing caulk as needed. Keeping gutters unobstructed and in working order and making sure there aren’t any shingle nails poking out of the edges of the roof are also important steps in preventative roofing maintenance.
Curt’s company uses a multi-layered approach to fall prevention and protection, including mandatory safety talks at the beginning of each day and monthly meetings with sales, operations and ownership. He believes that education, training and prevention are the best ways to control fall hazards.
Repairs
When the damage to a roof is severe, whether mold growth, missing or soggy shingles, serious leaks in heavy rains, or extensive decking damage underneath, a full replacement is typically required. But if the roof is still structurally sound and only needs a new shingle overlay or roofing material to look and function better, re-roofing can be a cheaper alternative.
A skilled roofing contractor can address issues quickly, preventing further wear and tear and a larger disaster from developing down the line. They can seal cracks, repair damaged shingles and tar paper, and address gaps and weakened areas. They can also provide proactive maintenance and inspections to identify potential problems early on, saving homeowners thousands of dollars in costly repairs down the road.
It’s important to know if a contractor offers a manufacturer or workmanship warranty and how long the coverage lasts. A manufacturer warranty is less expensive but only covers materials. A workmanship warranty provides more comprehensive protection, but it can be significantly higher in cost than the manufacturer’s option. Choosing the best coverage for your budget and needs is essential. A well-informed roofing contractor can help you make the right choice for your home.
