If you are a handy DIY person, there are many things to consider before you begin your metal roof painting project apart from how much money you are likely to save
The most important consideration you need to think about is your personal safety. This may not be an issue of course if, for example, your roof is flat and you are alert and aware of all the hazards around you, so preparing the surface, applying the primer and metal paint may not be too difficult.
On the other hand, if your roof has steep gables, is high off the ground or is difficult for you to stand up on, then the risk factor to your safety is increased greatly.
As a general rule, if your safety is compromised or likely to be put at risk then you should seriously consider hiring a qualified painter because they will have the know-how and skill to complete the job safely and professionally.
If you have assessed the risks involved and are intent on painting your roof then check your ladder to see if it is in top condition. If your ladder is showing signs of fatigue or is unsteady when placed upright then replace it or borrow a reliable one. Also before you even begin have a look at the weather conditions and forecast.
This will ensure you’re not caught out if it begins to rain while on the roof or when your newly painted roof is only half dried.
Wear non slip footwear but be aware many metal roofs can be very slippery under foot and special shoe braces should be used particularly if the roof has sharp angles. If there is moisture on the surface of the roof then wait until it dries.
Ensure you are not alone at home while you are painting in the event of an emergency or accident. For added protection while on the roof secure a harness to your belt and attach the lead to a firm section of the roof to prevent you from falling.
Finally, wear overalls if possible and other protective type apparel such as eye protectors and gloves if you need to use abrasive chemicals or other bonding agents in your preparation work.
