If your metal roof has deteriorated badly enough, a coating cannot save it. However, there are situations in which you will want to use metal roof restoration products because replacing your roof too soon is just as bad as waiting too long to replace it.
Metal Roofs Eventually Degrade
Metal roofs are coated with a protective finish. However, exposure to the elements will degrade this protective finish over time. Rust will eventually form on your roof, and will affect the structural integrity of the roof. The rust will also affect the aesthetics of your building. Metal roofs expand and contract based on temperature fluctuations. This process causes seams to open up, which can allow moisture to enter your roof. For this reason, you will need to apply new protective coatings to your metal roof and you will also need to have your metal roof replaced at some point.
Metal Roofs Can Be Repaired
You may need to patch leaks in your roof or you might need a new skylight. In other cases, your roof might need to have a spray applied or might need to have a roll coating applied. This is only a good option if your roof is in good condition.
You May Need a Commercial Roof Inspection
If you're not sure if you should restore or replace your roof, consider getting in contact with commercial roof inspectors. Commercial roof inspections can identify common warning signs of severe roof deterioration and will provide you with advice on how to best correct it. If your roof is still structurally sound, you may be able to repair the parts that are damaged.
The upside of having your roof completely replaced is that you will receive some tax breaks at the end of the year. However, if you want to save the most money and avoid having a negative impact on the environment, do not replace your roof until it is absolutely necessary. Also, by replacing your roof, your business will be disrupted as you finish your roof repairs.
The environment around your roof can shorten the lift of your roof. Chemicals and paint can impact the life of your roof. Also, your roof is less likely to accept coatings depending on the type of climate that your roof is placed in. Also, the type of metal roof you have will affect the type of repairs that are available to you and how expensive these repairs are.
