The Benefits of Metal Roofs and How to Repair Metal Roof Systems

The Benefits of a Metal Roof for Your Home

March 17, 2022 8 Read

While metal roofs are usually used for industrial buildings, the benefits of metal roof systems shine in residential homes. They offer several qualities that aren’t possible with standard asphalt shingles and can improve the value and durability of your home in a way traditional roofs just can’t. Let’s look at some of the benefits you can expect from a metal roof.

The Benefits of a Metal Roof for Your Home### Aesthetic appeal

​If you’re looking for a roof that will look fantastic and improve the value of your home, metal roofs are where it’s at. Modern technology has evolved them beyond their traditional steel looks – now they come in a range of styles, from flat to cedar wood shakes, allowing you to pick a perfect look for your home. Are you looking for something to stand out? Metal roofs also come in vibrant colors, including reds and intense yellows. If you want to learn more about the available styles that metal roof systems offer, a professional roofing company will give you more information.


Metal roofs are known to last 30+ years on a home, compared with just 15 on more traditional asphalt roofs. And since metal is fireproof and fade-resistant, you can expect your metal roof to still look great after decades of sun exposure. Not only that, but they’re wind-resistant up to 150mph (in most cases), which means they can handle the toughest of natural disasters without a problem.

Energy Efficiency

The US Department of Energy recognizes metal roofs as an ENERGY STAR product because of their excellent resistance to heat transfer. It makes them highly energy-efficient! As a result, you’ll see lower heating bills year-round and possibly even lower cooling costs during the summer.

Resistance to pests

Wood-boring insects like termites can wreak havoc on your home over time, but metal roofs with rigid surfaces are protected against these destructive pests. Even squirrels and birds are no match for metal; they can’t get traction once they land on it so that you won’t see any damage done by their claws.

Noise reduction

Ever notice how loud it can be when it’s raining out? Metal roofs help diminish this noise because of just how tightly woven the steel in them is. Also, with the rain bouncing off so smoothly, you won’t have to shout over your neighbor’s noisy puddles anymore.

Easy to Repair

A metal roof system comprises metal roof panels secured to purlins and supported by a metal or steel frame. The panels are typically made from aluminum, galvanized steel, copper, zinc, or stainless steel – all metals that can stand up well to normal wear and tear. Each metal roof panel is attached with screws and other hardware to be easily replaced if need be without having to purchase an entirely new metal roof.

How to Maintain Metal Roof Systems

So now that you’re familiar with the benefits of a metal roof system, let’s talk about their maintenance and how to repair them.

Regular Inspection

As with any roof system, the proper maintenance of a metal roof begins with regular inspections. A faded or loose standing seam means your roof is at risk of leaking or other issues down the line. Likewise, it is best to check all the seams and seals around your skylights, so they don’t develop leaks along their sealant lines because this can be just as dangerous. Likewise, check all the edges for damages, especially after a heavy storm.

Suppose you notice any spots on the roof surface where rust patches have begun to form, repair the area immediately to prevent further corrosion. Protect your metal roofing against mildew or moss growth by spraying vinegar onto affected areas (an acid-like vinegar won’t damage the metal itself), rinse them off and use a steel brush to prevent further growth from building up.

You may not see all individual panels of your metal roof without climbing on top of your roof. If you find it challenging to get to your roof, you can hire a professional roofing contractor to inspect your metal panels.

Installation of Metal Roof Panels

When it comes time to replace old metal roof panels, installation should be done by professional contractors who are experienced in working with metal roofs. They will carefully take measurements of your home’s roof cavity so the new panels will fit snugly over the top of the old ones without sagging or gaps. The nails or screws they use will ensure the new metal panels stay firmly.

How to Repair Metal Roofing### Minor Leaks Repair for Metal Roof

You can save money with a simple metal roof repair for minor repairs in many cases. The most common problem for metal roofing is a leak caused by broken sealant lines. You can try to mend the damaged area yourself using urethane sealant or roof cement typically used on flat roofs. Other causes of leaks for metal roofing are exposed fasteners and nails.

Sealant lines usually become exposed because water seeps through a defective or raised seam along the panel. Replacing your entire metal roof is wasteful since you can quickly fix leaks at exposed screw points with simple roofing cement available from home improvement stores.

Minor Holes Repair for Metal Roof

You can quickly repair small holes on your metal roof, and small rusted areas on panels with a metal roof repair kit found online or at home improvement stores. This kit contains patches in various shapes and sizes, but you can also use a heavier gauge steel cut from another section of the sheet’s metal. Just measure all your pieces first before cutting them out because once you make any alterations, they cannot be returned for credit.

Patching a small hole in your metal panel will fix a leak once and for all, but rust patches require more work. You can begin with light sand of the rusted area with 80-grit sandpaper or steel wool to remove any loose flakes of rust. Next, you should apply primer designed especially for steel roofs before applying spray-on paint or a top coat over your repair.

Major Holes Repair for Metal Roof

You can tackle the large hole in your metal roofing by carefully cutting out and removing a small section around it. Next, you should cut another piece of sheet metal to fit flush against the old one and fasten them together with roofing nails or screws inserted into existing holes. If you need to create new holes that line up with those on the other panel, pre-drill through both pieces using a drill bit designed for steel roofs.

When nails or screws penetrate such hard surfaces as metal sheets, they tend to bend easily and pull back during installation. To prevent this, you should use self-tapping mesh tabs underneath each screw or nailhead once it’s inserted far enough into your repair patch. This alternative adhesive method will hold the metal together as firmly as used nails or screws.

If you have a large area that needs re-coating, then applying a primer first is essential because it will seal out moisture and rust from beneath your paint job. It would help if you also used a special urethane roof cement designed for flat roofs to prevent leaks before adding a final topcoat coating over the repaired area.

When to Replace Instead of Repairing a Metal Roof

You should replace your metal roof in any case when a leak damages both the roofing material and interior ceilings below. In this instance, you will want to remove the old metal panels in one piece instead of patching them with another section or welding in a new piece.

The main disadvantage is that if you do not have professional experience in removing these materials, it can be pretty dangerous for anyone working from the ground up because you’ll need to lift heavy sheets without hurting yourself or anyone else. You also risk damage when using hoisting equipment provided by rental companies, so make sure they provide the necessary safety measures before signing on any dotted lines.

When to Call A Professional Roofing Company for a Metal Roof Repair

You should hire a professional roofing company if your metal panels are beyond simple patching or welding repairs, need recoating in large areas, or need assistance to remove them safely. Regardless of the size of your project or repairs needed, a professional service will have the necessary skills and equipment for any job.

Make sure you know what you’re getting into before signing on with a contractor because some might charge an hourly rate even though they quote a flat fee for the entire project. In this case, ask for an estimate that includes all labor and materials, so there won’t be any surprises after the fact.

Before selecting which roofing contractor you want to do business with, always get at least three estimates for quotes. It is the best way to compare prices and services, but be sure to hire someone qualified because their experience matters with this type of specialized work.

Any metal roof repairs require close attention to detail, significantly when cutting into or re-coating existing panels. You’ll want a contractor with years of experience working with metal roofing systems. After all, it only takes one mistake to turn a simple repair job into an expensive disaster for your home or business.
