Texas Roofing Inspection
Metal Roofing is becoming a popular option due to its aesthetics and long-lasting lifespan.

At KOG Roofing we want to give you the advantages and disadvantages of metal roofs so we can help to make an educated decision about whether or not to decide on metal roofing for your home or residence.

If you are thinking about buying metal roofing for your home, it is essential to consider the advantages and disadvantages of metal against other typical roof materials, like, asphalt, wood, or tile.

Metal Roof Advantages

Long Lifespan

If a metal roof is adequately installed, your roof should last just as long as the home, sealing out water, enduring strong winds, and easily shedding snow. Metal is insusceptible to fire, mildew, insects, and rot.
Warranties vary largely, but most roofing service providers back their products for 20 to 50 years. KOG Roofing also backs our warranty on all labor for 5 years.

Fire resistance

Because metal roof materials are noncombustible, they generally have a Class A fire rating. Just understand that component of a roof’s overall classification depends upon materials underneath the surface that could catch fire in rigorous heat. Most metal roofs that are installed over a combustible material like wood have a lower, Class C rating.


Compared to the weight of tile and asphalt roofs, metal roofing is very lightweight. As a result of the material’s lightweight, you can save money on building the reinforcing structure. As a matter of fact, if you’re building a house or building an add-on, you can often downsize or reduce the amount of roof support members.

Energy Savings

Metal reflects heat energy from the sun, reducing heat gain. This means you as a homeowner can save on energy needed for air conditioning throughout the day. Metal roofing can be applied over foam insulation that has very high R-values. Furthermore, many systems take advantage of dead-air space between the metal and roof deck to increase energy performance.

Roof Pitch

Most metal roofing materials can possibly be installed on gently pitched roofs without leaking. The minimal roof pitch generally is 3-in-12. This means the roof rises 3 inches for each horizontal foot.

Maximum shedding of rain and snow. Metal roofing is virtually impervious to rain and snow due to the fact that of the way the panels interlock and because the surfaces are hard and slippery. Moreover, the dark color of metal roofing will quickly warm in the snow, resulting in snowmelt.

Roofing installation

Most metal roofing materials are available in multiple-shingle segments or wide panels.

A proficient roofing contractor can install these promptly. If your roof is stripped off and a storm is on the way, shortening the process by a day or two may offer an essential advantage. Obviously, there are also substantial labor cost savings if you can alleviate and reduce the time of the roof installation.

Metal Roofing Disadvantages

Though metal roofing offers many benefits, there are a few disadvantages. Generally, metal roofing manufacturers have enhanced their products to solve many different of these concerns

Metal Roof Cost

The biggest drawback is the upfront cost. Metal roofing is comparable in cost to other premium roofing products. As a result of the material’s long-term longevity, the secret is that you will inevitably save the difference and a lot more if you stay in the house for an extensive amount of time.

Noisey Rain & Hail

Some homeowners enjoy the sound of rain tapping on a metal roof. For others, it’s like living inside a drum. In a rainstorm or hailstorm, living beneath thin sheets of metal is going to be noisier than living beneath thick slate or tile. The noise can be controlled by using materials that have structural barriers to minimize the drumming effect and by installing them over sound-deadening insulation and solid plywood.

Denting and Damage

A metal roof can dent if large hailstones fall on it. Copper and aluminum roofing, which is made from much softer than steel, are more prone to denting. However, there are some varieties of metal roofing that are guaranteed not to dent.

Possible Leaking Problems

A metal roof must be installed correctly. Roofs with exposed fasteners are particularly vulnerable to improper installation.

Expansion & Contraction

Because metal expands and contracts as it gets hot then cools down. Most new products have fastening systems that accommodate movement. Expansion and contraction on hot days can cause a wavy effect.


Metal roofing materials installed in large panels are more difficult to replace if damaged than individual shingles.
