Top 10 Questions for Roofer Applicator Interview

1. What are the different types of roofing materials and their pros and cons?

There are various roofing materials available, each with unique advantages and disadvantages. Here are a few common types:

• Asphalt shingles: Affordable, easy to install, and widely used. However, they have a shorter lifespan compared to other materials.
• Metal roofing: Durable, energy-efficient, and fire-resistant. However, it can be more expensive than other materials.
• Tile roofing: Long-lasting, fireproof, and aesthetically pleasing. However, it is heavier and more expensive than other options.
• Slate roofing: Durable, fireproof, and aesthetically appealing. However, it is very expensive and requires skilled installation.
• Wood shingles: Durable, fire-resistant, and environmentally friendly. However, they require regular maintenance and are prone to decay and insect damage.

2. How do you determine the slope of a roof?

Measuring the Roof’s Height and Horizontal Run

• Use a builder’s level to mark a reference point (A) at the base of the roof.
• Measure vertically from point A to the peak of the roof (B). This is the roof’s height (H).
• Measure horizontally from the base of the roof to the plumb line (C). This is the roof’s horizontal run (R).

Calculating the Roof Slope

• Divide the roof’s height (H) by the roof’s horizontal run (R). This gives you the roof slope ratio (H:R).
• Convert the roof slope ratio to a percentage using the formula: Slope (%) = (H/R) x 100.

3. What are the safety precautions you take when working on a roof?

Working on a roof involves inherent risks, so safety precautions are crucial:

• Wear appropriate safety gear, including a hard hat, safety glasses, gloves, and non-slip footwear.
• Use a sturdy ladder that is properly secured to the roof.
• Have a spotter or helper on the ground to assist and ensure safety.
• Be aware of weather conditions and avoid working during storms or high winds.
• Inspect the roof for any hazards, such as loose tiles or electrical wires, before starting work.

4. How do you install a new roof?

Preparation

• Remove any existing roofing material and inspect the roof deck for damage.
• Install underlayment to protect the roof deck from moisture.

Installing the Roofing Material

• Start at the bottom edge of the roof and work your way up.
• Overlap the roofing material according to the manufacturer’s instructions.
• Secure the roofing material using nails or screws.

Finishing Touches

• Install flashing around chimneys, vents, and other roof penetrations.
• Caulk all seams and joints to prevent leaks.

5. How do you troubleshoot and repair a leaking roof?

Locating the Leak

• Use a hose to simulate rainfall and check for any water penetration.
• Inspect the roof for any visible damage or missing tiles.
• Check the flashing around chimneys, vents, and other roof penetrations.

Repairing the Leak

• Replace any damaged or missing tiles.
• Seal any cracks or gaps in the flashing.
• Apply a waterproof sealant to the affected area.

6. What are the different types of roof underlayment and their uses?

• Felt paper: Traditional underlayment made from recycled paper, provides water resistance and helps prevent mold.
• Asphalt-saturated felt: Similar to felt paper, but treated with asphalt for added water resistance.
• Synthetic underlayment: Made from synthetic materials like polyester or polyethylene, lightweight, water-resistant, and tear-resistant.
• Ice and water shield: Self-adhesive underlayment used in areas prone to ice dams, provides additional water and ice protection.

7. What are the different types of roofing nails and their uses?

• Galvanized steel nails: Resistant to corrosion and commonly used for most roofing applications.
• Stainless steel nails: More expensive but highly corrosion-resistant, suitable for coastal areas or near saltwater.
• Aluminum nails: Lightweight and corrosion-resistant, ideal for metal roofing.
• Copper nails: Durable and resistant to rot and corrosion, often used for copper roofing.

8. How do you properly seal and caulk around a roof penetration, such as a chimney or vent?

Preparing the Surface

• Clean the area around the penetration thoroughly to remove any dirt or debris.
• Apply a layer of roofing cement to the base of the penetration.

Applying the Sealant

• Use a caulk gun to apply a bead of silicone-based sealant around the perimeter of the penetration.
• Smooth the sealant using a finger or caulk tool to ensure a watertight seal.

9. What are the signs of a damaged or failing roof?

• Missing or damaged shingles: Can lead to leaks and further damage.
• Curled or buckled shingles: Indicate underlying structural issues.
• Granule loss: Exposure of the asphalt base, reducing the roof’s protective layer.
• Sagging or bowing roof deck: Structural damage that can compromise the integrity of the roof.
• Visible water stains or leaks: Signs of a compromised roof system.

10. What are the different types of roof inspections and their purposes?

• Visual inspection: A general examination of the roof to identify any visible damage or issues.
• Infrared inspection: Uses a thermal camera to detect areas of moisture buildup or insulation problems.
• Drone inspection: Utilizes a drone to capture aerial footage and images of the roof, providing a comprehensive view.
• Wind mitigation inspection: Evaluates the roof’s ability to withstand high winds and is often required by insurance companies.
• Hail damage inspection: Assesses the extent of damage caused by hailstorms.
