The Importance of Summertime Safety for Commercial Roofing Crews

As a commercial roofing contractor with nearly a century of experience serving the Kansas City area, Cornell Roofing & Sheet Metal understands the critical importance of safety, especially during the sweltering summer months. Working on rooftops under the blazing sun poses significant risks, and prioritizing the well-being of our crews is paramount. Here are essential tips to ensure safety and prevent heat-related illnesses during summer roofing projects.

Hydration is Key

One of the primary risks during summer is heat illness, which can range from heat cramps to heat stroke. To combat this, staying hydrated is crucial. We encourage our crews to drink water frequently, even if they don’t feel thirsty. Electrolyte-replenishing drinks can also be beneficial to maintain the body’s salt balance.

Proper Clothing and Gear

Wearing lightweight, light-colored, and breathable clothing can help reduce heat absorption. Wide-brimmed hats, sunglasses, and sunscreen are also essential to protect against harmful UV rays. Additionally, utilizing safety gear designed to improve airflow and ventilation can make a significant difference.

Scheduled Breaks

Implementing regular breaks in shaded or cool areas is vital. We ensure that our roofing crews take frequent breaks to rest and cool down. These breaks should be scheduled, especially during the peak heat hours of the day, typically from 10 a.m. to 4 p.m.

Recognizing Heat Illness Symptoms

Training our crews to recognize the early signs of heat illness can prevent severe outcomes. Symptoms like heavy sweating, weakness, dizziness, nausea, or headache should be addressed immediately by stopping work, moving to a cooler area, and hydrating. At Cornell Roofing & Sheet Metal, the safety of our crews is our top priority. By implementing these summer safety tips, we ensure that our workers stay safe and healthy, allowing them to continue providing top-notch roofing services across Kansas City. Remember, a safe crew is an effective crew. Stay safe this summer!

Spring Seasonal Roofing Maintenance Tips for Commercial Buildings in Kansas City

Spring is upon us a little early this year. Now is the time for commercial building owners in Kansas City to turn their attention to essential maintenance tasks, particularly regarding their roofing systems. With over 95 years of trusted service, Cornell Roofing and Sheet Metal is here to provide expert guidance on spring seasonal roofing maintenance.

Inspect and Repair Winter Damage:

  • The first step in spring maintenance is conducting a thorough inspection to identify any damage caused by winter weather. From snow accumulation to freezing temperatures, the harsh conditions of winter can take a toll on commercial roofs. Look for signs of leaks, missing shingles, or damage to flashing and seals. Addressing these issues promptly can prevent further damage and extend the lifespan of your roof.

Clean Gutters and Downspouts:

During winter, gutters and downspouts can become clogged with debris such as leaves, twigs, and ice dams. This obstruction can impede proper drainage, leading to water pooling on the roof and potential leaks. Ensure gutters and downspouts are clear of debris to allow for efficient water flow away from the building.

Trim Overhanging Branches:

Overhanging tree branches can pose a risk to your commercial roof, especially during spring storms with strong winds. Trim back any branches that hang over the roof to prevent them from causing damage or puncturing the roofing material.

Schedule Professional Maintenance:

While DIY inspections are essential, nothing beats the expertise of a professional roofing contractor. Schedule a maintenance visit with Cornell Roofing and Sheet Metal to conduct a comprehensive inspection and address any issues before they escalate into costly repairs. Contact us now to set up an appointment today or call 816.252.8300.
