Can I get a metal roof installed over my old shingle roof?
Yes and no. At Rob’s General Contracting, we inspect each roof carefully before recommending this method to ensure a long-lasting, code-compliant installation.
- The current shingle roof must be relatively flat and free of major damage, rot, or structural issues. In addition, the current roof cannot have leaks around flashings like a chimney or dormer.
- Typically, purilin/furring lumber and high-heat synthetic underlayment are installed between the shingles and the new metal panels to prevent abrasion and improve performance.
Are there benefits to installing a metal roof directly over shingle roofing?
Installing over shingles can save on tear-off costs, reduce landfill waste, and provide an extra thermal barrier.
Does metal roofing cost more than shingles?
Yes, metal roofing is generally more expensive upfront than shingle roofing, but it can offer better long-term value.
While metal roofing costs more initially, it often pays off over time with longer life, fewer repairs, and better energy performance. At Rob’s General Contracting, we help homeowners weigh both options based on budget, goals, and long-term plans for the home.
Is a metal roof noisy when it rains?
Typical metal roof panels can be noisy when it rains - however, at Rob's General Contracting we use metal roofing panels with a fleece backing called CondenStop. This provides many benefits over typical metal roofing panels, including noise reduction during heavy rains.

What’s the difference between standing seam and exposed fastener metal roofing?
The key difference is in how the panels are attached and how the fasteners are protected:
- Standing Seam Metal Roofing features concealed fasteners and raised seams that lock together. This system offers a sleek appearance, superior weather resistance, and less maintenance over time—making it ideal for high-end residential or commercial use.
- Exposed Fastener Metal Roofing uses visible screws to secure the panels. It’s more affordable and faster to install but may require more maintenance, as the screws can loosen or the washers can degrade over time.
- At Rob's General Contracting, we provide expert installation of both standing seam metal and exposed fastener metal roofing
Do metal roofs come with warranties?
Yes! We offer both system and workmanship warranties on new metal roof installations. Warranty options will depend on the metal roofing system installed.

Exposed Fastener Metal Roofing
At Rob’s General Contracting, we take pride in delivering professional installation of ribbed metal panel roofing, an exposed fastener system that combines strength, durability, and affordability. This type of roofing is ideal for residential and commercial properties, offering a sleek and practical solution for long-lasting protection.
Can Metal Roofing Be Installed Over Shingles?
Yes, under the right circumstances. Many shingle roofs are excellent candidates for installing ribbed metal panels directly on top of the existing roof. This process can help homeowners save significantly on tear-off and disposal costs, while still achieving a durable and weather-resistant new roof.

Standing Seam Metal Roofing
At Rob’s General Contracting, we are experts in installing standing seam metal roofing, a premium roofing solution known for its clean aesthetic, long-term durability, and superior protection. Our standing seam roofing services offer a blend of style and function, making it an ideal choice for both residential and commercial properties in central and northeastern Pennsylvania.
Standing seam metal roofing is a concealed fastener system, meaning the fasteners used to attach the panels are hidden beneath the seams.
This not only gives the roof a sleek, uninterrupted appearance but also eliminates the risk of leaks or corrosion around exposed screws, ensuring a more durable and watertight roofing system. And thanks to the concealed fastener system and durable materials, standing seam roofs require minimal maintenance over their lifetime.

Concealed Fastener Design:
Unlike traditional exposed fastener systems, Tilcor’s CF Shingle features a concealed fastening system that keeps screws and fasteners hidden beneath the panels. This provides a seamless, clean appearance while enhancing the roof’s resistance to leaks and wear.

Metal Roof Coating
At Rob’s General Contracting, we provide professional metal roof coating services that enhance the performance, durability, and energy efficiency of your metal roof. One of our featured solutions is the Karnak 502 RC-W Elasto-Kote system, a premium elastomeric roof coating designed to extend the lifespan of your roof and provide superior protection against the elements.
This is a cutting-edge elastomeric roof coating system specifically formulated for metal roofs. As a self-priming, single-component thermoplastic rubber coating Karnak 502 offers a highly elastic and durable finish that adapts to the natural expansion and contraction of metal roofs. With a built-in rust inhibitor, it provides exceptional resistance to corrosion while sealing and waterproofing the surface.
Fastener Maintenance
At Rob’s General Contracting, we provide expert fastener maintenance services for exposed fastener metal roofing systems, ensuring your roof remains secure, leak-free, and performing at its best. One of the most important maintenance tasks for these roofs is the replacement of metal roofing screws, a procedure typically required every 10 years to maintain the roof’s integrity and longevity.
Why is Fastener Maintenance Necessary?
Exposed fastener metal roofing systems rely on screws with rubber or neoprene washers to secure the panels to the roof deck. Over time, these fasteners can degrade due to:
UV exposure: Sunlight can dry out and crack the rubber washers, reducing their effectiveness in preventing leaks.
Thermal expansion and contraction: The natural movement of the metal panels can cause screws to back out or loosen over time.
Corrosion: Prolonged exposure to moisture can lead to rust on the screws, compromising their holding strength.
Regular fastener maintenance is crucial to prevent water infiltration, ensure the roof remains securely fastened, and prolong the lifespan of your metal roof.
