Homeowners who are tired of worrying about the potential for leaks or the cost of periodically replacing their shingles may find themselves drawn to the idea of metal roofing. While the appearance of today's residential metal roofing is much more attractive than the silver sheets of metal used by past generations, it continues to offer the same level of strength and longevity that made metal roofing popular for farm use during the past century.
If you are planning to install a new roof and wonder if switching from your current shingles to metal roofing is a wise choice for your home, the following information can provide the answers you need to decide.
Can metal roofing be installed over existing shingles?
Metal roofing materials are very light in weight, making it possible to install them over existing roofing materials. If any type of underlayment, vapor barrier, or insulation is needed, it is added before the metal is installed. Wood furring strips, otherwise known as battens, are then used to support the metal roofing material and provide a suitable surface for fastening it securely to the existing roof.
When will shingles need to be removed before installing metal?
If the existing shingles are seriously degraded or damaged and have already begun to allow water to penetrate the surface, homeowners will likely want to have them removed so that the roof sheathing, rafters, and other elements underneath can be inspected for rot, mold, or weak spots that could affect the strength of the new metal roof. If underlying problems are found, homeowners will want to have damaged sections replaced before continuing with the installation of their new metal roof.
Should homeowners attempt to DIY their metal roof installation project?
While the process involved in installing a new metal roof sounds simple enough, homeowners who attempt their own roofing project may not have the tools or skills to safely and successfully complete it. Some common problems homeowners may experience during a DIY roofing project include:
- failing to recognize sagging roof lines caused by cracked or damaged rafters
- failing to use safety equipment to help prevent falls while working on the roof
- failing to install proper ridge vents to ensure good airflow and help prevent condensation issues from occurring
- failing to properly flash and seal around chimneys, plumbing stacks, and antennas to prevent leaks
Each home can present specific challenges during any type of roofing installation project. Homeowners who are considering switching from shingles to metal roofing can get the answers they need by discussing their situation with a reputable metal roofing contractor company, such as Blue Water Roofing, in their area.
