Have Questions? FAQ on Metal Roofing, Siding, Gutters & Snow Guards

Metal roofing is durable, energy-efficient, low-maintenance, fire-resistant, and resistant to extreme weather. It also reflects solar heat to reduce cooling costs in summer.

Metal roofing typically lasts 40–60 years or longer when properly installed and maintained.

Yes. In many cases, metal roofing can be installed over shingles or other existing roofs, saving time and money. A professional assessment is recommended to ensure suitability.

No. Properly installed metal roofs are not noticeably louder than traditional roofing. Insulation and underlayment can further reduce sound.

No. Metal roofs do not attract lightning. They are non-combustible and provide a protective barrier if lightning strikes.

Yes. Pre-painted panels are common, and you can repaint if colors fade. Use high-quality, rust-resistant coatings for longevity. More information is available in our blog.

Yes. Metal roofs are seen as a long-term investment. They can boost resale value and may reduce insurance premiums.

Minimal. Inspect for debris, clean gutters, and check for loose panels or fasteners. Panels come with a 40-year Kynar paint warranty from the manufacturer, and recoating is generally not required during this period.

Oil canning is a visible waviness in flat metal panels. It is purely cosmetic and does not affect structural integrity or waterproofing. Using textured panels or lighter colors can reduce its appearance.

Metal siding is durable, low maintenance, fire resistant, and performs well in extreme weather. It resists rot, insects, and impact damage, and can be installed as part of an energy-efficient wall system when properly detailed and insulated.

Metal siding is durable and long-lasting, but flat panels can naturally show waviness or “oil canning,” which is purely visual and not a defect. Over time, caulking around roof penetrations like chimneys or skylights may need to be replaced by a professional every 10–15 years to maintain a watertight seal.

Metal siding typically lasts 40–60 years or longer when properly installed and maintained. It outlasts many traditional siding materials because it does not rot, warp, or attract insects.

No. Metal siding does not significantly increase interior temperatures. Heat performance depends on insulation, ventilation, and wall assembly design rather than the exterior cladding material itself.

Yes. Metal siding is noncombustible and does not ignite or contribute fuel to a fire, making it a fire-resistant exterior cladding option.

Yes. Metal siding can be repainted and cleaned when needed. Repainting requires proper surface preparation and coatings designed for metal, while routine cleaning can be done with mild detergent and low-pressure water.

Oil canning is a visual waviness that can appear in flat metal panels. It does not affect the structural integrity or weather resistance of metal siding and is considered an aesthetic characteristic rather than a defect.

Yes. Most metal siding profiles can be installed either horizontally or vertically depending on your design preference and the manufacturer’s guidelines. Vertical installation helps shed water more efficiently, while horizontal installation can create a different visual style. Professional installation is recommended to ensure proper fastening and alignment.

Common signs include sagging, rust, cracks, leaking seams, frequent clogs, water overflowing during rain, or puddling near your foundation. If cleaning doesn’t fix the problem, replacement is often the best solution.

Faulty gutters or downspouts can lead to roof damage, rotted fascia or siding, foundation issues, basement water intrusion, and moisture damage inside walls if problems persist.

No. Gutters should handle heavy rainfall when properly sized, sloped, and free of debris. Overflow usually indicates clogs, improper pitch, undersized gutters, or insufficient downspouts.

Aluminum gutters typically last 20–30 years, while steel gutters can last longer in harsh climates when properly maintained. Lifespan depends on material, installation quality, and exposure to weather.

Aluminum gutters are lightweight, cost-effective, and resistant to corrosion. Steel gutters are stronger and better suited for areas that experience heavy snow or severe weather. The best choice depends on budget, climate, and durability needs rather than maintenance differences.

A general rule is one downspout for every 20–40 feet of gutter. Roof size, pitch, rainfall intensity, and gutter capacity can all affect the required number.

Downspouts should discharge at least 3–4 feet away from the foundation. If water tends to pool, extensions may need to carry water farther based on site conditions and local codes.

Gutter covers can reduce how often gutters need cleaning, but they don’t eliminate maintenance. In many cases, they still require periodic removal to access and clean the gutter trough.

Most residential installations are completed in one day. Larger or more complex homes may take 2–3 days, while commercial projects can take longer depending on size and height.

Snow guards and snow bars are snow retention systems designed to control the release of snow and ice from metal roofs. Instead of allowing large sheets of snow to slide off at once, they help release snow gradually and reduce the risk of injury or property damage below. 

Snow guards are recommended when sliding snow or ice could land on people, vehicles, walkways, entrances, or lower roof sections. Roof slope, panel type, snow load, and site conditions all factor into whether snow retention is needed. 

Snow guards are not typically required by building codes, but they may be specified by local authorities, architects, or engineers when roof snow could create a safety hazard. Requirements vary by location and project conditions. 

Without snow guards, snow and ice can release suddenly from a metal roof. This can create safety hazards and may damage gutters, vehicles, landscaping, or lower roof sections. 

When properly specified and installed, snow guards do not damage metal roofs. Non-penetrating clamp-on systems are designed to attach without drilling, helping preserve the roof’s watertight integrity. 

Snow guards must be properly designed for the roof type and snow load. Inadequate spacing, improper attachment, or using systems not suited for the roofing profile can lead to uneven snow release or long-term roof issues. These risks are avoided with correct system selection and installation. 

Corrugated metal roofs are fastened through flat overlap sections designed to manage water penetration. Many snow guard systems require multiple fasteners placed along panel ribs or seams, often relying on sealants or gaskets in areas not intended for long-term watertight attachment. Because of this increased risk, we do not recommend snow guard systems on corrugated metal roofing. 

• Leaking: This is the most common skylight problem and can be caused by damaged seals, cracks in the glass, or issues with the flashing. 
• Cracks: Look for cracks in the glass or frame, which can indicate structural damage. 
• Condensation: Excessive condensation can be a sign of poor insulation or a leaking skylight. 
• Difficulty Opening/Closing: If a skylight that's meant to open is difficult to operate, it may indicate a problem with the mechanism. 
• Age: Skylights typically have a lifespan of 10-20 years, so if yours is nearing that age, it might be time for a replacement. 

•  Resealing: If the leak is due to a damaged seal, a professional contractor can reapply sealant to the damaged surface. 
• Flashing Repair: Damaged flashing can be repaired or replaced to prevent leaks where the skylight meets the roof. 
• Glass Replacement: If the glass is cracked, it may need to be replaced. 
• Skylight Replacement: In some cases, it may be more cost-effective to replace the entire skylight, especially if it's heavily damaged or nearing the end of its lifespan.
