Metal roofing has become an increasingly popular choice for homeowners in recent years. Standing seam metal roofs, in particular, offer many benefits that make them a smart investment for most homes. Here is what you need to know before installing standing seam metal roofing.
What is Standing Seam Metal Roofing?
Standing seam metal roofing consists of long panels of metal that run vertically from the ridge of the roof to the eaves. The panels are held together and water-tighted by raised vertical seams that join adjacent panels. This creates a clean, sleek look compared to other metal roof styles.
The seams are fastened to the roof deck, but not to each other, allowing the panels to expand and contract independently. This avoids buckling and oil-canning effects from temperature changes. Standing seam metal roofs require little to no penetration of the metal, enhancing their durability and weather-resistance.
Benefits of Standing Seam Metal Roofs
There are many reasons why standing seam metal roofs have become a top choice for residential and commercial buildings:
Durability
Metal roofs can last 50 years or longer with little to no maintenance required. The panels resist corrosion, fire, rot, and insect damage better than traditional roofing materials like asphalt shingles. Standing seam panels are also impact-resistant against hail, falling branches, and other debris.
Weather Resistance
The raised seams prevent water infiltration, even under extreme weather. Metal roofing is an especially good option for homes in areas prone to heavy rain, snow, and ice dams. The slick surface also allows snow and ice to slide off more easily than other roofs.
Energy Efficiency
Metal roofing has insulating properties that help reduce energy costs. The reflective surface deflects sunlight, lowering cooling costs in summer. In winter, the panels help prevent heat loss and reduce the need for heating.
Aesthetic Versatility
Metal roofing comes in a wide range of colors, styles, and finishes to complement any architectural design. The sleek, clean lines provide a modern look. Standing seam panels can also mimic shake, slate, and tile roofs for a more traditional style.
Increased Property Value
A standing seam metal roof can greatly improve your home’s curb appeal and resale value. The increased durability and resistance to elemental damage make it an attractive selling point.
Environmental Sustainability
Metal is easily recyclable. Many roofing manufacturers use recycled content in their panels. The long service life also reduces waste and disposal compared to replacing other roof types.
Disadvantages to Consider
While standing seam metal roofs have many perks, they also come with a few potential drawbacks:
- Higher upfront cost – Metal roofing is more expensive initially than asphalt shingles and some other materials. However, the increased durability and longevity offset the cost over the lifetime of the roof.
- Professional installation required – The panels and seams require special knowledge and tools to install correctly. DIY is not recommended, so professional roofing contractors should be hired.
- Can be noisy in rain – Metal panels can make pitter-patter sounds during rainstorms, though advanced engineering has helped reduce noise.
- Conducts heat – The panels can get very hot in direct sunlight, transmitting heat into the attic. Proper insulation and ventilation are important.
- Difficult to repair – Minor repairs require special expertise. Complete panel replacement may be needed if the metal is punctured or extensively damaged.
What to Look for in a Standing Seam Metal Roof
To get all the benefits of a standing seam metal roof, be sure to consider:
- Reputable manufacturer – Go with an established brand that provides at least a 30-year warranty on their products.
- Metal thickness and coating – 24 gauge steel with G90 galvanized coating or thicker is recommended for durability and longevity.
- Qualified local contractor – Ask for examples of previous standing seam metal roof installations. Experience with these roofs is vital.
- Flashing and accessories – Ensure all penetrations through the roofing will be properly flashed and sealed against leaks.
- Energy efficiency options – Inquire about insulation, radiant barriers, and cool roof color finishes to maximize energy savings.
- Aesthetic choices – Select from many colors, finishes, and seam styles to achieve your desired look and complement other exterior features.
Installation Process Overview
Installing a standing seam metal roof is best left to the professionals, but here is a general overview:
- The roof deck is inspected and repaired if needed to provide a smooth, stable base.
- Underlayment like ice/water barrier and synthetic felt is installed over the deck.
- Flat metal sheets or clips are fastened to the roof deck. Standing seam panels will attach to these later.
- Panels are placed one by one and secured to the clips/fasteners. Adjacent panels are overlapped.
- The seams where panels join are folded over and crimped using a mechanical seamer tool to create the signature raised vertical ribs.
- Flashing is added wherever the roof abuts walls, vents, and other protrusions.
- The ridges and eaves are trimmed and finished.
The installation process takes precision and expertise, so always have it done by an experienced professional roofing contractor. Many manufacturers also require installers to be certified in their branded products.
FAQs about Standing Seam Metal Roofs
How long do standing seam metal roofs last?
With proper installation and maintenance, a standing seam metal roof can last 50 years or longer before needing replacement. Some may last over 70 years if coated and cared for properly over time.
Are standing seam metal roofs energy efficient?
Yes, metal roofing provides excellent insulating properties to reduce heating and cooling costs. Reflective finishes and additional radiant barriers can further boost energy efficiency.
Do metal roofs require more maintenance than asphalt shingles?
No, in fact metal roofs require much less maintenance over their lifespan. Asphalt shingles need periodic repairs and sealing to extend their shorter lifespan. Metal roofs mainly just need occasional cleaning.
Do I need to coat or seal a standing seam metal roof?
Coatings are not necessarily required but can help extend the lifespan. Periodic re-coating is recommended by manufacturers for optimal durability. Seaming and fasteners also need occasional inspection.
Are standing seam metal roofs environmentally friendly?
Absolutely. Metal roofing contains recycled content, is fully recyclable, and has an exceptionally long service life. This creates much less waste and use of resources than other roofing materials over time.
Can metal roofing withstand hail and extreme weather?
Standing seam metal roofing is one of the most impact-resistant options against hail, wind, heavy snow loads, and severe storms. The panels resist damage and stay watertight better than shingles.
Conclusion
Standing seam metal roofing provides unparalleled durability, weather resistance, energy savings, and versatility for residential homes and buildings. Though higher in upfront cost than asphalt shingles, the long lifespan of metal roofing provides excellent return on investment and can greatly boost your home’s value. With proper installation by qualified professionals, a standing seam metal roof will protect your investment and provide beauty and performance for decades to come.
