Best Metal Roof Coating to Stop Leaks

Best Metal Roof Coating to Stop Leaks:
Long-Term Protection & Weather Proofing

Leaks in metal roofs can lead to costly water damage, rust and structural issues if left untreated. The best solution? A high-performance metal roof coating that provides long-term weather proofing and corrosion resistance. At Sharmans, our industry-leading coatings – Delcote®, Seamsil® and Plygene® Gutterline – seal leaks, protect vulnerable areas and extend roof life without the need for expensive replacements.

Why You Need a High-Performance Metal Roof Coating

Metal roofs are durable and long-lasting, but over time, they can develop leaks due to weather exposure, corrosion, thermal movement and general wear and tear. If left untreated, leaks can cause expensive water damage, structural deterioration and increased maintenance costs.

The best metal roof coating provides:

✅ Permanent Weather Proofing
Seals leaks and prevents future water ingress.

✅ Corrosion Resistance
Protects against rust and oxidation.

✅ Seam & Fastener Protection
Stops leaks at vulnerable points.

✅ Cost-Effective Restoration
Extends roof life without the need for full replacement.

Common Causes of Metal Roof Leaks & How Coatings Prevent Them

Cut Edge Corrosion:
Metal roofs corrode over time, especially along edges. Seamsil® stops corrosion and seals vulnerable areas.

Weathering & UV Damage:
Prolonged exposure leads to cracking and leaks. Delcote® provides a protective, long-lasting barrier.

Failed Seams & Fasteners:
Water can penetrate around fasteners and panel joints. Seamsil® & Delcote® reinforce these weak points.

Gutter Leaks:
Damaged or rusted gutters allow water to pool. Plygene® Gutterline provides a watertight solution.

How to Choose the Best Metal Roof Coating for Your Needs

Several factors determine the right weather proofing solution for your metal roof:

✅ Roof Age & Condition
Minor leaks can be sealed with a coating, but severe damage may require additional repairs.

✅ Weather Exposure
Is your roof exposed to heavy rain, snow, or high UV levels?

✅ Leak Locations
Are leaks coming from seams, fasteners, or gutters?

✅ Budget Considerations
Roof coatings offer significant cost savings compared to full replacement.

At Sharmans, we provide expert assessments to recommend the best metal roof coating for your specific needs.
