How Often Should You Seal Your Metal Roof?
Your metal roof has a special coating that covers the entire surface of the metal panels and protects them from rust. This coating must be kept in good condition for your roof to look nice.
If you have been using your metal roof for years, it will still provide you with protection from outside elements as long as its coat is not disturbed. In addition to damage caused by weather, pest infestation, foot traffic, and other natural causes can also make your steel ceiling appear worn down.
To avoid this problem, proper cleaning and maintenance should be included in your annual budget. Proper care of your steel roof includes sealing it at least once each year. Here are some tips for proper maintenance of your metal roofs:
When To Seal Metal Roofs
You should seal your steel roof at least once each year. Metal roofing is not cheap to replace and can even be dangerous when their coat is peeled off. If they are not properly cared for or if they have been covered with layers of dirt that obscure them, you may have difficulties spotting rust spots until these become large enough to cause leaks in your ceiling. Many homeowners do not follow the recommended schedule of sealing metal roofs because they believe that this task is optional or unnecessary.
In order to avoid the embarrassment of leaks in your ceiling, experts recommend sealing metal roofs as soon as you notice discoloration or damage on their surface. In many cases, paintwork and roof work will cost more compared to a once-a-year sealant application.
What To Expect From A Metal Roof Sealant Appointment?
Before setting up a metal roof sealant appointment, it is important that you first discuss this with your contractor. They can then tell you which materials should be used for the job and how often these materials need to be replaced by the time you have been using them for at least five years.
There are several types of materials available for application which vary in price range depending on their type and quality. Here are the most common materials used to protect your roof:
These are among the most popular and effective types of sealants available in the market today. Polyurethane-based sealants can be applied using airless sprayers for large roofs, paint rollers for small metal roofs, and brushes or mop buckets when several people will be applying them at once. You may also use a long-handled squeegee that is designed specifically for this job and costs about $ 15 per unit.
They are also very effective against rust which is why many homeowners prefer them over other types of sealants.
Water soluble-based sealants
These are usually used on small roofs because they are easier to apply compared to polyurethane-based products. While water soluble-based sealants are less effective compared to polyurethane-based materials, they provide better value for the money since they only need reapplication once or twice a year on average depending on your climate conditions exposure to sunlight.
Nevertheless, water soluble-based sealants are also effective in protecting metal roofs from rust damage. They are available for both powder and liquid formulations which can be applied with a paint roller, brush or mop bucket depending on the amount you will need to use at one time.
These are commonly used by homeowners who have pets because they are non-toxic products that do not contain chemicals or other harmful ingredients that could be dangerous when ingested by their furry friends. However, natural oils are not suitable for roof surfaces that are exposed to ultraviolet light because they can cause the steel surface to discolor over time.
Natural oils are among the cheapest types of sealants available in the market today. They are non-toxic, odorless, and have long shelf lives which means you do not have to worry about frequent replacements every few months. However, these products require some effort on your part since you will need a paintbrush or roller to apply them evenly on your metal roofing panels.
As with water soluble-based sealants, natural oils are also less potent compared to polyurethane-based sealant applications when it comes to rust protection. These products are also effective against mildew growth but does not offer any protection against the damaging effects of ultraviolet light.
There are many ways for you to determine how often you need to apply sealants on your roof surfaces. One of the most accurate methods is to contact a roofing specialist company that has serviced your property before because they should know what type of sealant was used during the installation. You can also take note of past problems with leaks or damages that have occurred in the past even if these were repaired immediately by installing flashing and adding extra nails around the eaves and at ridge areas.
