If you’re looking for durability and resistance to the elements, steel shingles are an excellent option. They offer long-lasting protection and come in a range of styles, providing a sleek and modern appearance.
Steel shingles are made from galvanized steel and designed to mimic the look of traditional asphalt or wood shingles. These shingles are stamped or formed into various shapes and profiles, creating a distinctive appearance that can complement a wide range of architectural styles. Here are some advantages of choosing steel shingles:
- Low maintenance: Regular inspections and cleaning are typically enough to keep steel shingles in optimal condition. Their resistance to mold, mildew, and rot further contributes to their low-maintenance nature.
- Fire Resistance: Steel is a non-combustible material, making steel shingle roofs highly fire-resistant.
- Environmentally Friendly: Many steel shingles are made from recyclable materials. When it’s eventually time to replace your roof, the old shingles can be recycled rather than added to landfills.
- Energy Efficiency: Some steel shingle options feature reflective coatings that can help reduce energy consumption by reflecting sunlight and heat, thus keeping your home cooler during hot summer months.
- Resistant to Pests and Rot: Steel shingles are immune to pests like termites and do not rot, ensuring the integrity of your roofing system.
- Warranties: Most steel shingles often come with robust warranties, offering homeowners reassurance and protection for their investment.
Steel shingles offer the perfect blend of durability, aesthetics, and longevity. With their low maintenance requirements and resistance to environmental factors, they can be a valuable addition to your home. Whether you’re looking for a roof that will last for decades or an option with customizable styles, steel shingles are an excellent choice for many homeowners.
A standing seam metal roof earns its reputation for durability and longevity. Standing seam roofing is often used in both commercial and residential roofing.

- Architectural Versatility: Standing seam roofing’s vertical panels provide a contemporary, clean appearance that can enhance the architectural aesthetics of your home. It comes in various profiles and colors to match different styles.
- Weather Resistance: The raised seams and concealed fasteners of this roofing system offer excellent resistance to water penetration. It minimizes the risk of leaks and water damage.
- Fire Resistance: Metal roofing materials are non-combustible, making standing seam roofs highly resistant to fires and enhancing the safety of your home.

WHAT OUR CUSTOMERS ARE SAYING
LINDSAY S.
“Would use TMJ and recommend them again and again and again. We had a huge and unique project with our roof replacement and various other needs and TMJ took it on without hesitation, got creative, brought in as many people as it took, reached out and utilized other resources as needed, was very responsive, kind and helpful and did literally whatever it took to get the job done and done well! We were very impressed with the crews – they all did great work, cleaned up like nothing happened and were professional. Thank you to all the fantastic and skilled crews, to Curt, Mike and Josh and Makenzie!”
BRYAN F.
“I can’t say enough about how good our experience has been with TMJ Construction. They were prompt and complete with the bid and stuck to the timeline they gave us for installation. Their crew showed up early and took good care not to damage the landscaping around the house. The job went quick and their clean-up was excellent. The new roof looks great and we’re very pleased. Contractors who come through as they promise can be hard to find. TMJ delivers.”
DAMAN A.
“We had Mike from TMJ help us with an insurance claim. He was super helpful and easy to work with. They were able to replace our roof and siding way faster than I ever imagined and it looks amazing. I will use them again!”
