How To Install Metal Roofing

Considerations For Professional Metal Roof Installations

A roof made of metal shingles will often last the lifetime of the home with proper maintenance. With shingles made of materials like steel, aluminum, and copper, but designed to look like slate or wood, this is an attractive roofing choice that is much more durable and offers more benefits.

A metal roof is a much sought-after home investment. When homeowners begin to research metal roofing, many are afflicted when they learn that installation costs are higher and may need to be done professionally. There are many aspects to consider in every step of re-roofing with metal shingles when deciding whether to learn how to install metal roofing or hire a professional.

First, will the old roofing need to be removed? Some metal shingles can be laid down right on top of the old asphalt shingles, but this can depend on the type of metal shingles being used, how many layers are already in place as well as the building codes and permits, if any. Some building inspectors will limit a roof to two layers of shingles.

However, the light weight of metal shingles can be an advantage in this case.Another thing homeowners will need to consider when learning how to install metal roofing is the type of materials that will be used. Will the roof be considered architectural or structural? Architectural roofing materials are sufficient with standard attic ventilation, while structural metal roofs are thicker and may need specialized barriers, extra insulation, and strong ventilation. However, structural roofs are rare in smaller buildings like homes.

Roof pitch will also have a play in learning how to install metal roofing. Manufacturers rate roofing products for ranges of roof pitch, or the ratio of how far the roof reaches back to how high the roof rises  (run to rise). The pitch will determine what type of waterproof seal is needed, and roofs with different pitches in separate areas of the roof may require different roofing materials.Metal roofing products do have more regulation and know-how than standard shingles.

Considering that a properly installed metal roof may still be in good working condition 100 years from now, like many of the first installed metal roofs from the early 1900s, homeowners have much to gain by installing properly to begin with. The investment can then be allowed to pay for itself over years of virtual maintenance-free home protection.
