Metal Roof Sealing

Metal roofs have become increasingly popular in the Portland area, offering sleek aesthetics, impressive durability, and resistance to fire. With proper care and maintenance, a metal roof can last anywhere from 40 to 70 years. One essential aspect of maintaining your metal roof and ensuring its longevity is using the right metal roof sealant. Grime Busters, your expert roof cleaner in Portland, is here to guide you through the world of metal roof sealants, helping you choose the best one for your needs.

What Is Metal Roof Sealant?

Metal roof sealants serve two primary purposes: repairing minor leaks and protecting your roof from environmental factors like UV rays and excess moisture. It's crucial to use a sealant specifically designed for metal roofs, as other roofing materials require unique sealants due to their distinct characteristics.

Sealant Categories

There are two main categories of metal roof sealants: water-based and solvent-based. Each category has its advantages and considerations. Let's explore the five main types of metal roof sealants that fall under these categories:

1. Acrylic Sealant

  • Ideal for deflecting UV rays, making it suitable for sun-exposed areas.
  • Not recommended for flat roofs as it doesn't provide complete waterproofing.

2. Polyurethane Sealant

  • Not recommended for metal roofs due to stiffness in cold weather.
  • Requires a primer for application, adding time and cost.

3. Silicone Sealant

  • Highly recommended for metal roofs, providing excellent protection against moisture and UV rays.
  • Works well in all weather conditions but comes at a higher price.

4. Rubber Sealant

  • Comes in a thin, water-based formula, making it easy to apply.
  • Ideal for small leaks and cracks.

5. Sealant Tape

  • Applied directly to roofing material, reducing potential mess.
  • Affordable and suitable for repairing small issues but not recommended for extensive damage.

Which Areas Require Sealant?

Downspouts: Downspouts are crucial for channeling water away from your roof and foundation. Sealant prevents water from seeping into the seams, reducing the risk of leaks and potential water damage.

Fasteners: Fasteners, such as screws and nails, can create openings in your roof when not properly sealed. Sealant ensures these areas remain watertight, preventing leaks around fasteners.

Gaps: Gaps in your metal roof can occur over time due to expansion and contraction. Sealant fills these gaps, maintaining the roof's integrity and preventing water infiltration.

Gutters: Gutters play a critical role in directing rainwater away from your property. Sealing gutter seams and joints ensures that water flows smoothly and doesn't leak into your roof or foundation.

Joints: Joints where different sections of your metal roof meet are vulnerable to water penetration. Sealant creates a waterproof barrier, protecting against leaks in these areas.

Nails: Nails can loosen or corrode over time, creating openings for water. Sealant around nail heads keeps them secure and prevents leaks.

Trim: Trim around the edges of your roof is susceptible to water intrusion if not properly sealed. Sealant helps maintain a watertight seal, preventing water from seeping under the trim.

Seams: Seams are potential weak points in your metal roof. Properly sealing seams is essential to ensure that water cannot penetrate and cause damage to your property.

How Long Does Roof Sealant Last?

The lifespan of metal roof sealants varies by brand, but most typically last between 10 to 20 years. Given that a metal roof can last up to 70 years, it's crucial to replace the sealant periodically to prevent leaks. Grime Busters recommends scheduling annual inspections with your preferred local roofing contractor, who will assess the condition of your sealant during their inspection.
