Our perception of metal roofs is that of an impregnable roofing material. As per its tests and roofing contractor experience, metal roofs can withstand the most terrible of hail, rain, and snowstorms. In fact, it can even come out unscathed in many cases. However, even with its superior protective capabilities, metal roofs can suffer from damages requiring repairs.
Both standing seam and corrugated roofing and tin or aluminum roofing will require crucial emergency roof repairs especially if no reliable and top-notch Leduc AB roofer can reach your location at the fastest possible time. If you need to repair your standing seam metal roof leaks, Do It Yourself has an excellent and comprehensive guide right here.
How to Repair a Standing Seam Metal Roof
What You’ll Need

- Screw Set
- Roof Caulk
- Acrylic Roof Coating
- Butyl Tape
- Putty Knife
- Wire Brush

A standing seam metal roof is designed for durability and strength, but sometimes, it can still get damaged due to impact caused by a falling tree branch or a storm. Below are steps on how to repair it.
Step 1 – Assess the Damage
Climb up the roof for visual inspection. If a foreign object punctures the roof, the damage requires patching. If the surface is merely scratched, application of a good roof coating product is sufficient.
Step 2 – Prep the Area
Whatever repair method you use, it is necessary to prep the area, so that the patch, coating or paint that will be applied will adhere firmly on the surface. To do so, wash the area with detergent solution and then rinse with water. Next, mix oxygen bleach and water at 50:50 ratio and use it to remove organisms such as mold or algae from the surface, that can affect with the adhesion of the patch, coating or paint. Allow to dry. Apply paint stripper on the area and then scour loose paint and the primer using a putty knife. Use a wire brush if necessary. Sand the surface afterward, using medium grit sandpaper.

However, a great number of homeowners use corrugated metal roofs instead of standing seam material. While it introduces a more mechanical curb appeal, corrugated metal roofs are affordable yet share many of the useful capabilities superior standing seam metal roofs have.
On the other hand, this means they can suffer from possible metal roof leaks and will require repairs during emergencies. SF Gate Home Guides has an excellent step-by-step procedure when it comes to metal roof repairs. Learn more about it below.
How to Fix Leaks in a Corrugated Metal Roof
Corrugated metal roofs are vulnerable to excessive moisture and damage from strong winds. The individual panels are attached to wood or metal trusses with steel nails or screws that can rust and cause leaks. Strong winds can separate the overlapping edges of the panels and allow the roof to leak. Fixing leaks in a corrugated metal roof starts with locating the source of the leaks. From there, the method used to fix a particular leak depends on the cause.
Access the roof using en extension ladder.
Inspect each row of nails or screws by walking on the row instead of between rows. The latter can bend the metal panels.
Pull out any nails that are raised up using a nail bar.
Drive a 1 1/2-inch aluminum screw-nail where a nail was removed, using a hammer. Drive a screw-nail next to a nail where the head is rusted away. For steel screws where the heads are rusted away, use a cordless drill and screw-tip attachment to drive a 1-inch galvanized-steel screw next to the screw.
Apply urethane roof cement where a new nail or screw was installed with a plastic putty knife. (Read More Here)
At this point, you might be questioning why metal roofs seem impregnable and requiring repairs often. One way to prevent possible metal roof leak repairs is to install metal roofs the right way.
However, proper installations only reduce the likelihood of metal roof leaks and damages, but a huge reduction is better than none at all. Sheffield Metals has an excellent guide to help you make sure your metal roof installation goes smoothly — check it out below.
7 Common Problems That Could Affect Your Metal Roof
Knowing about the problems that could occur on a metal roof system will help prevent issues from the very start, resulting in less time and money necessary for repairs.
No product in the world is perfect, no matter how much money it’s worth or how well it’s cared for. You could be in a lucky situation where nothing ever goes wrong with something you’ve purchased or you could experience one or more problems at any given time. It all just depends.
Metal roofing is no different.
While there are variables affecting the problems that could occur with metal roofing, sometimes things just happen that are beyond human control. This might not be the answer you’re looking for, but just know that there tend to be fewer long-term problems associated with metal roofing than asphalt shingles or concrete tiles.
Here at Sheffield Metals, we think it’s important to educate consumers about the potential common problems with a metal roof that could very easily happen or not happen. In this article, we will discuss:
- The top seven common problems that could occur with a metal roof
- Potential ways and methods to remedy or avoid the problem

Top 7 Common Problems with Metal Roofing
#1: Oil Canning
According to the Metal Construction Association (MCA), oil canning is defined as:
“Visible waviness in the flat areas of metal roofing and metal wall panels. In technical terms, oil canning is referred to as elastic buckling (more commonly known as “stress wrinkling”). It can occur in any type of metal panel: steel, aluminum, zinc, or copper.”
To be clear, oil canning is an inherent characteristic of nearly all metal roof or wall installations. Think of oil canning as the metal on a standing seam metal system being over-stressed and unable to hold a flat form, which causes the metal to give in and create visible waves. Oil canning is easily one of the hottest topics in metal roofing because it can be difficult to define and measure. There are a number of reasons that oil canning can occur, including:
- Over-production—such as extreme pressure during the coiling of the metal
- Frequent stress from coil slitting (cutting) and rollforming panels
- Inadequate space allotted for thermal expanding and contracting of the panels
- Changes to the structure’s original form that puts tension on or moves the panels
- Improper usage, handling, and storage by installers
- For example, if a panel is not installed according to the specified dimensions of the structure, it could generate oil canning
Contractors should always follow industry standard installation details
Luckily there are ways to reduce the likelihood of oil canning, some of which include:
- Purchasing a thicker metal
- Using a rib roller profile to break up the amount of flat space on a panel
- Choosing a low-gloss or matte finish to reduce reflectivity, which can decrease the visibility of oil canning
- Buying tension-leveled (stretched) metal, as this coil is already stretched beyond the point where it cannot return to its original state
- Install the roof over a flat “in-place” roof deck
- Most importantly: Choose a skilled and experienced installer who is knowledgeable about the ways to avoid oil canning
