Clogged gutters and downspouts can lead to water accumulation on the roof, increasing the risk of leaks and structural damage. Make it a routine to clean these areas to ensure proper water drainage. This task, while seemingly minor, significantly contributes to maintaining the integrity of your roof. If you're not comfortable doing it yourself, a roofing contractor can assist in ensuring the system is clear and functioning efficiently.
Proper handling and storage of roofing materials are crucial to preventing accidents and injuries. Contractors should be trained in lifting techniques that minimize strain on the body and in safely securing materials on the roof to prevent them from becoming hazards. Additionally, clear communication and coordination among team members can help prevent accidents related to material handling.
The physical demands of roofing cannot be overstated. A great roofer possesses not only the physical endurance to handle the rigors of lifting, climbing, and kneeling but also the mental fortitude to maintain focus in challenging conditions. Working in extreme weather and at elevated heights requires a keen awareness of safety protocols. Knowledge of protective measures, such as those mandated by the Occupational Safety and Health Administration (OSHA) in the United States, is essential. A commitment to safety is a hallmark of a professional roofer, ensuring not only their own well-being but also that of their team and clients.
While vegetative roofs offer numerous advantages, they also present challenges that need careful consideration by roofing contractors. The added weight of soil and plants requires a thorough assessment of the building's structural capacity. Climate conditions and plant selection are crucial factors that influence the success of a green roof. Contractors must also be prepared to navigate regulatory requirements and secure necessary permits, as green roofing projects often fall under specific environmental and building codes. Safety remains a paramount concern, as working at heights with potentially unstable materials necessitates stringent adherence to safety protocols to protect workers from falls and other hazards.
Regulatory frameworks play a pivotal role in the adoption and installation of photovoltaic products in roofing. In regions like the United States, the Occupational Safety and Health Administration (OSHA) has established guidelines to ensure the safety of workers handling these advanced materials. Roofing contractors must navigate these regulations, which often involve additional safety measures due to the electrical components of photovoltaic systems. This includes specialized training and equipment to prevent falls and electrical hazards. Staying informed and compliant with these regulations not only protects workers but also instills confidence in clients who are considering these innovative technologies for their homes and businesses.
In effect, choosing professional roof installation over a DIY approach offers numerous benefits, from ensuring safety and quality to providing long-term cost savings and increasing property value. While DIY projects can be rewarding, the complexities and risks associated with roofing make it a task best left to the experts, who can deliver both peace of mind and exceptional results.
Roofing projects can affect local ecosystems, particularly when materials are sourced and installed without considering their ecological footprint. The extraction of raw materials, such as mining for metals, can lead to habitat destruction and biodiversity loss. By choosing sustainably sourced materials and implementing eco-friendly installation practices, roofing contractors can minimize these impacts. This might include using local materials to reduce transportation emissions or selecting products certified by environmental standards.
Solar shingles are designed to withstand various weather conditions, offering durability and resilience similar to traditional roofing materials. This makes them a smart choice for roofing contractors looking to provide clients with long-lasting roofing solutions. Unlike bulky solar panels, solar shingles integrate smoothly into the roofline, preserving the home's architectural integrity and enhancing curb appeal. By choosing solar shingles, homeowners can enjoy the dual benefits of a protective roof and an attractive exterior that boosts property value.
Experience is a critical factor when selecting a roofing contractor. An experienced roofer is likely to have encountered a variety of roofing issues and developed effective solutions. Ask how long they have been in business and whether they specialize in the type of roofing material you prefer. A contractor familiar with modern technologies like solar shingles or vegetative roofs could offer innovative solutions tailored to your specific needs.
When deciding between DIY and professional roof repairs, it's important to weigh the risks and benefits. DIY repairs can save money and provide a sense of accomplishment, but they come with potential safety risks and the possibility of inadequate repairs if you're not experienced. On the other hand, professional roofers bring expertise and safety assurance, albeit at a higher cost. They also offer warranties on their work, which can be invaluable if issues arise in the future. Consider the long-term implications of your choice, as improper repairs can lead to more significant problems down the line.
The Occupational Safety and Health Administration (OSHA) provides a robust framework to keep roofing teams safe on the job. These guidelines are not merely suggestions but mandatory practices designed to minimize risks associated with roofing tasks. OSHA emphasizes the importance of fall protection, given the elevated heights at which roofers work. This includes the use of guardrail systems, safety nets, and personal fall arrest systems. Additionally, OSHA mandates proper training for workers to recognize hazards, ensuring that they are equipped with the necessary skills to navigate potential dangers. By adhering to these standards, roofing contractors can significantly reduce the incidence of work-related injuries and fatalities.
While following OSHA guidelines is crucial, creating a culture of safety within the roofing team is equally important. This involves going beyond mere compliance to instill a mindset where safety is a shared priority. Regular safety meetings, open communication channels, and the encouragement of reporting potential hazards without fear of reprisal are all vital components. By fostering an environment where every team member feels responsible for their own safety and that of their colleagues, roofing contractors can enhance the overall safety of their operations. This proactive approach not only helps in preventing accidents but also boosts morale and productivity.

A roofer, roof mechanic, or roofing contractor is a tradesperson who specializes in roof construction. Roofers replace, repair, and install the roofs of buildings, using a variety of materials, including shingles, single-ply, bitumen, and metal. Roofing work includes the hoisting, storage, application, and removal of roofing materials and equipment, including related insulation, sheet metal, vapor barrier work, and green technologies rooftop jobs such as vegetative roofs, rainwater harvesting systems, and photovoltaic products, such as solar shingles and solar tiles.[1][2]
Roofing work can be physically demanding because it may involve heavy lifting, climbing, bending, and kneeling, often in extreme weather conditions.[1] Roofers are also vulnerable to falls from heights due to working at elevated heights. Various protective measures are required in many countries. In the United States these requirement are established by the Occupational Safety and Health Administration (OSHA) to address this concern.[3][4][5] Several resources from occupational health agencies are available on implementing the required and other recommended interventions.[6][7][8]
According to data from the U.S. Bureau of Labor Statistics (BLS), as of May 2022[update], there were 129,300 individuals working as roofers in the construction industry. Among that population, a majority of roofers (93%; 119,800) were contractors for Foundation, Structure, and Building Exterior projects.[9][10] In terms of jobs outlook, it is predicted that there will only be a 2% increase in job growth from 2022 to 2032 in the United States. Approximately 12,200 openings are expected each year in this decade. Most of the new jobs are likely to be offered to replace roofers who retire or transition out of the trade.[1]
In Australia, this type of carpenter is called a roof carpenter and the term roofer refers to someone who installs the roof cladding (tiles, tin, etc.). The number of roofers in Australia was estimated to be approximately 15,000. New South Wales is the largest province with an 29% market share in the Australian Roofers industry (4,425 companies). Second is Victoria with 3,206 Roofers (21%).[11]
In the United States and Canada, they're often referred to as roofing contractors or roofing professionals. The most common roofing material in the United States is asphalt shingles. In the past, 3-tab shingles were used, but recent trends show "architectural" or "dimensional" shingles becoming very popular.[12]
Depending on the region, other commonly applied roofing materials installed by roofers include concrete tiles, clay tiles, natural or synthetic slate, single-ply (primarily EPDM rubber, PVC, or TPO), rubber shingles (made from recycled tires), glass, metal panels or shingles, wood shakes or shingles, liquid-applied, hot asphalt/rubber, foam, thatch, and solar tiles. "Living roof" systems, or rooftop landscapes, have become increasingly common in recent years in both residential and commercial applications.[13][14]
Roles and responsibilities of roofing professionals include:[1]
Beyond having common duties such as replacing, repairing, or installing roofs for buildings, roofers can also be involved in other tasks, including but is not limited to:
Roofing is one of the most dangerous professions among construction occupations since it involves working at heights and exposes workers to dangerous weather conditions such as extreme heat.[15] In the United States as of 2017, the rate of fatalities from falls among roofers is 36 deaths per 100,000 full-time employees, ten times greater than all construction-related professions combined.[16] In the United States, the fatal injury rate in 2021 was 59.0 per 100,000 full-time roofers, compared to the national average of 3.6 per 100,000 full-time employees.[17] According to the U.S. Bureau of Labor Statistics, roofing has been within the top 5 highest death rates of any profession for over 10 years in a row.[18] For Hispanic roofers, data from 2001–2008 show fatal injuries from falls account for nearly 80% of deaths in this population, the highest cause of death among Hispanics of any construction trade.[19][20]
A major contributing factor to the high fatality rates among roofers in the United States is the nature of the craft which requires roofers to work on elevated, slanted roof surfaces. Findings from qualitative interviews with Michigan roofing contractors also found hand and finger injuries from handling heavy material and back injuries to be some of the more common task/injury combinations.[21]
Ladder falls contribute to the rates of injury and mortality. More than half a million people per year are treated for fall from ladder and over 3000 people die as a result.[22] In 2014 the estimated cost annual cost of ladder injuries, including time away from work, medical, legal, liability expenses was estimated to reach $24 billion.[22] Male, Hispanic, older, self-employed workers and those who work in smaller establishments, and work doing construction, maintenance, and repair experience higher ladder fall injury rates when compared with women and non-Hispanic whites and persons of other races/ethnicities.[23]
Ladders allow for roofers to access upper level work surfaces. For safe use, ladder must be inspected for damage by a competent person and must be used on stable and level surfaces unless they are secured to prevent displacement.[3]
Nearly every industrialized country has established specific safety regulations for work on the roof, ranging from the use of conventional fall protection systems including personal fall arrest systems, guardrail systems, and safety nets.
The European Agency for Safety and Health at Work describes scenarios of risk (fall prevention, falling materials, types of roofs), precautions, training needed and European legislation focused on roof work.[6] European directives set minimum standards for health and safety and are transposed into law in all Member States.
In the United States, OSHA standards require employers to have several means of fall protection available to ensure the safety of workers. In construction, this applies to workers who are exposed to falls of 6 feet or more above lower levels.[3][24] In the United States, regulation of the roofing trade is left up to individual states. Some states leave roofing regulation up to city-level, county-level, and municipal-level jurisdictions. Unlicensed contracting of projects worth over a set threshold may result in stiff fines or even time in prison. In some states, roofers are required to meet insurance and roofing license guidelines. Roofers are also required to display their license number on their marketing material.
Canada's rules are very similar to those from the U.S., and regulatory authority depends on where the business is located and fall under the authority of their local province.
In 2009, in response to high rates of falls in constructions the Japanese Occupational Safety and Health Regulations and Guidelines amended their specific regulations. In 2013 compliance was low and the need for further research and countermeasures for preventing falls and ensuring fall protection from heights was identified.[25]
The United Kingdom has no legislation in place that requires a roofer to have a license to trade, although some do belong to recognized trade organizations.[26]
The purpose of a PFAS is to halt a fall and prevent the worker from making bodily contact with a surface below. The PFAS consists of an anchorage, connectors, body harness and may include a lanyard, deceleration device, lifeline or suitable combination of these.
Beyond these mandatory components of the PFAS, there are also specific fall distances associated with the functioning of the arrest system. Specifically, there is a total fall distance that the PFAS must allow for to assist the worker in avoiding contact with the ground or other surface below. The total fall distance consists of free fall distance, deceleration distance, D-ring shift, Back D-ring height, and Safety margin. In addition to the fall distance requirements for each component of the PFAS, the anchorage of the PFAS must also be able to support a minimum 5,000 pounds per worker.[4]
OSHA regulations have several requirements. The free fall distance, to the distance that the worker drops before the PFAS begins to work and slows the speed of the fall, must be 6 feet or less, nor contact any lower level. The deceleration, the length that the lanyard must stretch in order to arrest the fall must be no more than 3.5 feet.[4] The D-ring shift, the distance that the harness stretches and how far the D-ring itself moves when it encounters the full weight of the worker during a fall, is generally assumed to be 1 foot, depending on the equipment design and the manufacturer of the harness. For the back D-ring height, the distance between the D-ring and the sole of the worker's footwear, employers often use 5 feet as the standard height with the assumption that the worker will be 6 feet in height, but because the D-ring height variability can affect the safety of the system, the back D-ring height must be calculated based on the actual height of the worker. The safety margin, the additional distance that is needed to ensure sufficient clearance between the worker and the surface beneath the worker after a fall occurs, is generally considered to be a minimum of 2 feet.[3]
A fall restraint system is a type of fall protection system where, the goal is to stop workers from reaching the unprotected sides or edges of a working area in which a fall can subsequently occur. This system is useful where a worker may lose their footing near an unprotected edge or begin sliding. In such a case, the fall restraint system will restrain further movement of the worker toward the unprotected side or edge and prevent a serious fall. Although fall restraint systems are not explicitly defined or mentioned in OSHA's fall protection standards for construction,[24][4] they are allowed by OSHA as specified in an OSHA letter of interpretation last updated in 2004.[27] OSHA does not have any specific requirements for fall restraint systems, but recommends that any fall restraint system be capable of withstanding 3,000 pounds or at least twice the maximum predicted force necessary to save the worker from falling to the lower surface.[3] There are no OSHA specifications on the distance from the edge the restraint system must allow for a falling worker, and although a likely very dangerous practice, the OSHA letter of interpretation states that as long as the restraint system prevents the employee from falling off an edge, the employee can be restrained to "within inches of the edge."[27]
Guardrail systems serve as an alternative to PFAS and fall restraint systems by having permanent or temporary guardrails around the perimeter of the roof and any roof openings. OSHA requires the height of the top of the rail to be 39-45 inches above the working surface. Mid-rails must be installed midway between the top of the top rail and the walking/working surface when there is no parapet wall at least 21 inches high. Guardrail systems must be capable of withstanding 200-pounds of force in any outward or downward direction applied within 2 inches of the top edge of the rail.[3][24]
Safety net systems use a tested safety net adjacent to and below the edge of the walking/working surface to catch a worker who may fall off the roof. Safety nets must be installed as close as practicable under the surface where the work is being performed and shall extend outward from the outermost projection of the work surface as follows:[4]
| Vertical distance from working level to horizontal plane of net | Minimum required horizontal distance of outer edge of net from the edge of net from the edge of the working surface |
|---|---|
| Up to 5 feet | 8 feet |
| More than 5 feet up to 10 feet | 10 feet |
| More than 10 feet | 13 feet |
Safety nets must be drop-tested with a 400-pound bag of sand, or submit a certification record prior to its initial use.[4]
Warning lines systems consist of ropes, wires, or chains which are marked every 6 feet with high-visibility material, and must be supported in such a way so that it is between 34 and 39 inches above the walking/working surface.[4] Warning lines are passive systems that allow for a perimeter to be formed around the working area so that workers are aware of dangerous edges. Warning lines are only permitted on roofs with a low slope (having a slope of less than or equal to 4 inches of vertical rise for every 12 inches horizontal length (4:12)).[28] In the context of roofing fall protection, warning line systems may only be used in combination with a guardrail system, a safety net system, a personal fall arrest system, or a safety monitoring system. The warning line system must be erected around all sides of the roof work area.[4]
Safety monitoring systems use safety monitors to monitor the safety of other workers on the roof. Safety monitors must be competent to recognize fall hazards. The safety monitor is tasked to ensure the safety of other workers on the roof and must be able to orally warn an employee when they are in an unsafe situation.[4]
Multi-layered approaches to fall prevention and protection that use the hierarchy of controls can help to prevent fall injuries, incidents, and fatalities in the roofing industry.[7][8] The hierarchy of controls is a way of determining which actions will best control exposures. The hierarchy of controls has five levels of actions to reduce or remove hazards – elimination, substitution, and engineering controls are among the preferred preventive actions based on general effectiveness.
Resources are available to assist with the implementation of fall safety measures in the roofing industry such as fall prevention plans,[23][29] a ladder safety mobile application,[30] infographics and tipsheets,[31] toolbox talks,[32] videos and webinars,[1] and safety leadership training.[2] Many of these resources are available in Spanish and additional languages other than English. The recommended safety measures are described next.
In terms of job outlooks, it is predicted that there will only be an 1% increase in job growth from 2021 to 2032. The job openings (15,000) are expected to replace roofers who will retire or transition out of the trade.[9]
Solar Roof installation is one of the fastest growing trends in the roofing industry due to the nature of solar roofs being environmentally friendly and a worthwhile economic investment. Specifically, solar roofs have been found to allow homeowners to potentially save 40-70% on electric bills depending on the number of tiles installed.[33] The US federal government has also begun incentivizing homeowners to install solar roofs with potential eligibility for 30% tax credit on the cost of a solar system based on federal income taxes.[34]
Across 14 researched markets, roofing contracting companies have reported that they have received more frequent calls regarding potential metal roof installations. For instance, one company used to receive 5-6 calls in total regarding metal installations but recently, they have received 5-6 calls weekly for inquiries regarding metal roof installations.[35]
