Metal roof corrosion has long been a big concern causing problems and additional costs for the building owners and managers and in the construction industry.
Some people are used to metal roof rusting. They know very well that after a specific period of time, their roof will begin to rust and corrode and they have to fix or replace them.
So, you may be wandering the best solution for your metal roof corrosion. But more important question is: Are there any other roofing materials – with a lower price and higher durability – that can replace the metal roof of your house with the lowest maintenance costs?
When metals are exposed to chemicals or electrochemical reactions, it is called corrosion. When they are exposed to air and moisture, it is iron oxidation or rust. The color of metal roof rusting is brown or red, while the color of metal roof corrosion might be green or blue.
What causes rust and corrosion in metal roofs?
Water & Oxygen are the main components to create iron oxide and speed up rust and corrosion in metal roofs.
Moisture is one of the main reasons of rust and corrosion in metal roofs. But if you are currently living in humid climate rusting is inevitable.
All metal or steel roofs have a low resistance to acid rain and salt. But some metals start to corrode and rust sooner than other types.
Most people think zinc coating and primers on steel roofs can completely prevent them from corrosion and rust. But the fact is unfortunately galvanized steel does not resist corrosion and rust. Same goes to color-coated steel roofs. But why even galvanization process do not prevent from metal roof corrosion and rust?
During manufacturing – when turning them into sheets – or installation process, the cuts and scratches on the steel – which most probably happens – can create situations in which water, oxygen or other chemicals react easily with the steel or metal roofs, resulting in rapid corrosion and rusting.
Roof rusting and corrosion can be costly and annoying. But choosing the best coating materials for your roofs can save lots of money, energy and time. Besides, you do not need to worry about maintenance or repair in the near future. The following factors can be very helpful:
Lifespan of metal roofs depends on some factors such as the correct installation of the roof – protective coating of the metal or galvanized roofs – the geographical environment i.e. marine environment can speed up the process of metal roof corrosion and rust, etc. If maintained properly, metal roofs last up to 30 years.
There are some issues with having a metal roof above your head. Such as:
UPVC is the best replacement for metal roof panels. UPVC is a new generation of lightweight and durable roof sheets and wall cladding. It has solved all the problems with steel roofing especially when it comes to metal roof corrosion.
UPVC roof coatings play as leak barriers. Due to their 4 cm high wave, they create an excellent overlap on the roof. Therefore, roof leaks rarely happen in these sheets, and that is only when they are not installed correctly. Meanwhile air circulation flows well under these sheets, too and lower your cooling costs. This will also help reduce roof corrosion.
Another reason theses exceptional roof sheets prevent from roof corrosion compared to metals; is that they are highly durable against acidic and alkaline conditions and acid rain has no effect on them.
For factories that are working in chemical industry and are worried that their chemical products will speed up their metal roof corrosion, Unplasticized Polyvinyl Chloride (UPVC) roof material, is the only cost-effective solution that can last longer than metal roofs.
UPVC anticorrosion roof
UPVC roof sheets are the best alternatives for steels and metals. They do not have the problems as of metal roof corrosion. Some of these pros are as follows:
Fastener corrosion in metal roofs Vs UPVC anticorrosion screws
Sepidfam Varna is the first UPVC roof and wall manufacturer in Iran. Our products are specifically designed for areas with highest probability of rust and corrosion.
UPVC materials are the best protective coatings for metal roof corrosion and rust. They are very well applicable in every situation and even for replacement you do not need to remove the previous layer of roof. Just stick it on top and it will work for many years with the least maintenance expenses.
