When installing roofs for homes, homeowners prefer metal roofs due to their long-lasting nature and easy maintenance. Metal roofs can often stand for many years compared to a standard shingle roof. Metal roofs are so tough that it takes a lot of time and strength to damage their roofs, and in most cases, the repairs are associated with installation errors. Even though metal roofs are strong, an inspection every 2 years is needed. Some serious damages are associated with metal roofs, which can be big if neglected. Read the article to know more about the solutions needed for a damaged metal roof of your house.
How do Metal Roofs Get Damaged?
Even metal roofs are designed to be resistant to damage. There can be some damage to your metal roof due to some reasons below.
- Poor installation of metal sheets. Poor caulking, sealants, and flashing can lead to damage.
- Damages to the roof caused by rust, coatings are coming off, failure of sealants, damages caused by broken tree branches, and other climatic conditions.
The Dangers Of Damaged Roof
If the metal roof is damaged, it can lead to the following.
- Moisture enters the rooms, and walls are damaged
- Ceiling tiles are damaged
- Start of insect problems

Some Common Problems And Solutions For Damaged Metal Roofs
The benefits of a metal roof are significant as they last for 60-70 years and are 100% recyclable. The benefits of metal roofs can be enjoyed only when properly installed, and if the maintenance is poor, it can lead to many other problems. Here are some of the common problems and their solutions.
Metal roofs often react with oxygen present in the air, which leads to corrosion. Rain and wind can accelerate corrosion. Even though a protective layer is present on the sheet, the layer gets weakened by rain and wind. To prevent corrosion of metal roofs, the metals have to be coated with special paint to prevent the metal roof from getting in contact with air and wind.
2. Openings In Penetration Flashing
Metal roofs are also prone to expansion and contraction, due to which the metals keep moving. The movement creates stress at the point of attachment and also causes penetrations. It is difficult to move or remove and reassemble metal roof panels, unlike the shingles. The solution to this problem is that metal roofs should be installed by a metal roofing professional to avoid mistakes.
3. Fasteners Backing Out
Metal roofs have typical fasteners, which can be either nails or screws. Over time, these fasteners have the tendency to move down or up, which can be due to many other reasons. The uplift caused by wind can also lead to a fastener back out. The screws or fastener backouts are to be checked regularly, and if there is any problem, the screws should be tightened, and the fastener backouts need to be repaired.
4. Scuffing And Scratching
Metal roofs can also be subjected to scuffing and scratching in their life cycle. Most metal roof manufacturers ensure that the coil is not scratched during the slitting, recycling, or transportation. The installation team also takes care to avoid scuffing or scratching. At the time of installation, there is by chance that there are scratches that can be easily fixed with the help of paint or a touch-up pen designed to match the color of a metal roof.
5. Dissimilar Metals Combined
In the installation process, there is a chance that two different metals are combined which can lead to staining, degradation, and also a potential failure of the system. At the installation time, discuss with the team to see if the metal roof goes well with the other materials chosen for screws and other small items.
6. Chalking And Fading
Chalking refers to the white residue formed due to the exposure of metal roofs to UV rays. The residue is visible on paint on the coated metal and mainly happens due to resin breaking down. Fading also refers to the breakdown of paint due to over-exposure to UV lights and chemicals in the atmosphere, which causes the paint to fade. Chalking and fading can be solved by using paint variants that cover chalking and fading, which is mentioned on the paint manufacturer’s warranty.
