Roof Flashing: The Unsung Hero of Leak Prevention

Flashing is one of the most important—and most overlooked—parts of a roofing system.

What Is Flashing?

Flashing is thin metal (usually aluminum or galvanized steel) installed around roof joints and penetrations to redirect water away from seams.

Where It’s Used:

• Chimneys
• Skylights
• Valleys
• Roof edges
• Around vents and pipes

Common Flashing Issues:

• Rust or corrosion
• Improper installation
• Cracked caulking or sealant

Pro Tip: Leaks near a chimney or vent are often flashing failures, not shingle problems.

🛰️ Smart Roofing Technology: The Future is Now

Smart tech isn’t just for thermostats—roofs are getting smarter too.

Emerging Innovations:

• Solar Roofs: Shingles that double as power generators (Tesla Solar Roof, GAF Timberline Solar)
• Drone Inspections: Faster, safer, and highly detailed roof inspections
• Infrared Moisture Scanning: Detects leaks under the surface
• Smart Gutters: With built-in sensors to alert you to blockages or overflows
• Energy-monitoring systems: Track how much your roof is saving you

Industry Tip: These technologies aren’t just cool—they can improve safety, reduce labor costs, and extend roof lifespan.

🧾 How to Read a Roofing Estimate (and Not Get Burned)

Roofing estimates can be confusing if you don’t know what to look for.

Key Elements of a Transparent Estimate:

• Full scope of work (tear-off, underlayment, flashing, ventilation)
• Type, brand, and quantity of materials
• Warranty terms (both labor and materials)
• Timeline and payment schedule
• Cleanup and disposal fees
• License and insurance info

Warning Signs:

• Vague descriptions like “roof work”
• No mention of flashing or ventilation
• Large deposit required before materials are delivered

🏗️ Roof Replacement vs. Re-roofing: Know the Difference

Re-roofing:

• Adds a second layer of shingles over the old one
• Cheaper and faster
• Only possible once and only with asphalt shingles

Full Replacement:

• Complete tear-off down to the decking
• Addresses hidden damage (like rot or mold)
• Longer lifespan, better performance

Best Practice: If your roof is older than 15 years or has underlying issues, go for a full replacement—even if re-roofing is allowed.

🧮 Roof Slope and Pitch: Why It Matters

Slope affects everything from material choice to drainage.

What is Roof Pitch?

Measured as rise over run (e.g., 6:12 means 6 inches of rise for every 12 inches of horizontal distance).

Low Slope (<3:12):

• Requires special membranes or metal
• Prone to water pooling

Medium to Steep Slope (4:12–9:12):

• Suitable for shingles, tile, metal
• Great for shedding rain and snow

High Pitch (>9:12):

• Visually dramatic
• More expensive to install and maintain due to access issues

Fun Fact: Steep roofs can reduce long-term water damage but may require extra safety measures during installation.

🛑 Roofing Red Flags During Home Purchase

Buying a house? Don’t forget to look up. Here’s what to ask or spot before signing:

• When was the roof last replaced?
• What type of roofing material is used?
• Are there signs of sagging, missing shingles, or staining?
• Is there evidence of attic leaks?
• Any active or past insurance claims?

Pro Tip: Always get a separate roofing inspection, especially for older homes. Standard home inspectors may not go onto the roof.
