At ECC Chimney Service, we know proper chimney lead repair keeps your Connecticut home dry and safe. Faulty lead flashing can cause leaks, masonry damage, and expensive repairs. That’s why we adhere to International Residential Code (IRC) and NFPA 211 standards for durable, code-compliant chimney maintenance. Forget shortcuts like tucking lead 1/2 inch with silicone—we’re your certified chimney experts for waterproof chimney solutions that last. Here’s how we do it right and why shallow tucks fail.
Why Lead Flashing Matters
Lead flashing seals where your chimney meets the roof, blocking water from entering your home. Over time, weather and wear can crack or loosen lead, requiring lead flashing repair. Done properly, repairs protect for decades. Done wrong, they lead to chimney leaks, masonry repair needs, or fire hazards.
How ECC Chimney Service Handles Lead Repair
Our process follows IRC and NFPA 211 guidelines to ensure your chimney stays secure and leak-free:
- Inspection: We offer a free chimney inspection to check lead flashing for damage or gaps, ensuring flue liners meet NFPA 211 Section 14.9 for safe combustion containment.
- Quality Lead: We use Code 4 or thicker lead for durability, resisting splits during shaping or expansion, unlike thinner codes.
- Proper Installation:
- Weaving into Shingles: By far the best option, we weave lead flashing into the roofing shingles, interlocking it with each course for a seamless, watertight seal. This method, aligned with IRC Section R903.2, outperforms surface-applied flashing by preventing water infiltration even in heavy storms.
- Step Flashing: We embed lead at least 1.5 – 2 inches into mortar joints, secured with wedges or clips, to anchor it against wind and weather.
- Counterflashing: We overlap step flashing, extending into masonry to divert water, meeting NFPA 211 standards for chimney protection.
- Expansion Allowance: We shape lead to handle thermal movement without buckling, ensuring durability for chimney maintenance.
- Sealing: We use butyl rubber or polyurethane sealants for exposed areas, ensuring UV resistance. Where lead is tucked under shingles or flashing, we may apply silicone beneath (not exposed to sun) to keep everything tight and leak-free, enhancing chimney sealing.
- Final Check: We confirm clearances and integrity per NFPA 211 Chapter 14, eliminating fire risks or structural issues.
Why Tucking Lead 1/2 Inch with Silicone Fails
Some roofers tuck lead flashing just 1/2 inch into mortar and seal it with silicone, but this shortcut spells trouble:
- Water Blow-By and Leaking: A 1/2-inch tuck is too shallow to stop water blow-by, allowing rain to seep past the flashing and leak into your home’s walls or ceilings, causing costly interior damage.
- Weak Anchorage: Per IRC Section R903.2, flashing must be securely fastened. Shallow tucks loosen in Connecticut’s freeze-thaw cycles, requiring chimney crack repair.
- Silicone Degradation: Silicone breaks down under UV rays and temperature shifts, cracking within years. This leaves gaps for chimney leak repair and undermines chimney waterproofing.
- Code Violations: NFPA 211 demands durable seals. Silicone and shallow tucks fail to meet IRC standards, risking inspection issues.
- Moisture Trapping: Silicone can trap water against lead or mortar, speeding up corrosion and decay, complicating brick chimney repair.
- Short-Term Fix: Unlike proper leadwork (50+ years), silicone repairs fail in 5–10 years, leading to chimney rebuilding or masonry repair costs.
