Can you install a metal roof over shingles?

Are you considering a roof replacement and wondering if you can lay down a new metal roof over your existing shingles? The answer, in almost every case, is a resounding yes. This is just one of the many reasons why metal roofs are gaining popularity, and Tesson Roofing is here to guide you through the process.

The Advantages of Installing Metal Over Shingles

Metal roofs offer a host of benefits, and one standout advantage is the ability to install them over existing shingles. Here’s why it’s a smart choice:

1. Time and Cost Savings:

  • Traditional roof replacement involves tearing off the existing shingles, a process that is not only time-consuming but also expensive. With a metal roof, you can skip this step, saving both time and money.

2. Lightweight Yet Strong:

  • Metal is incredibly strong, yet surprisingly lightweight, weighing less than a pound per square foot. This is in stark contrast to asphalt shingles, which can weigh up to four pounds per square foot. The overall load on your home structure is minimally increased, ensuring structural integrity.

3. Enhanced Insulation:

  • Adding a metal roof over existing shingles provides an additional layer of insulation. This helps in preventing heat and cool air from escaping, contributing to energy efficiency and cost savings on heating and cooling bills.

4. Heat-Blocking Properties:

  • Metal roofs are excellent heat blockers. They reflect heat away from their surfaces instead of absorbing it. This means that the extra insulation from your shingle roof will not act as a heat trap, keeping your home cooler in the summer.

Factors to Consider During Installation

While installing a metal roof over shingles is generally straightforward, a few considerations should be kept in mind:

1. Approval from Local Authorities:

  • Check with your local building and zoning departments to ensure they approve of metal-over-shingle installations.

2. Address Existing Issues:

  • If your shingle roof has leaks or structural problems, these should be addressed before the installation begins.

3. Underlayment Considerations:

  • Adding underlayment on top of the shingles is recommended to prevent granules from contacting the metal, potentially leading to corrosion. Your Tesson Roofing contractor will guide you through suitable options.

Benefits of Sturdy Metal Roofs Beyond Installation

Choosing Tesson Roofing for your metal roof replacement not only saves you the cost of tearing off the old roof but also brings long-term benefits:

    • Metal roofs are virtually impervious to damage, standing strong against hail, ice storms, gale-force winds, and searing summer heat.

    • With their inherent strength, metal roofs require minimal maintenance, avoiding regular and expensive repair jobs.
