When it comes to your roof, there is no black and white answer. Repaint? Repair? Replace? Well, it depends on your budget, the extent of the damage and what you are trying to achieve.

Bear in mind, that replacing a commercial roof can be a costly exercise and should only be done if you really have too. In the below article, we will discuss your options and outline what you need to consider in your decision-making process.

What Is the Current Condition of Your Roof?  

Will a new paint job suffice? Or is it rusty, are there holes? Rust may only be present in your flashings, if this is the case, it is a rather lower cost than replacing the entire roof. Of course, it could just be that the existing paint has faded and is beginning to flake. Our team of professionals can assess your roof and let you know what your best course of action will be.  

What Will Be Involved in Repainting It?

Sometimes it would be nice just get in and paint, but if you want the paint to last and be an effective coating on your roof then you need to prepare the surface correctly. When it comes to an older roof, it will typically require a moss treatment followed by water-blasting. Blasting is not about high pressure but rather water direction and spin in the nozzle to drive loose paint off before recoating the roof. The next step is to apply spot priming and then we move on to recoating the whole roof with two good coats of high-quality roof paint.

What Is the Cost of a New Roof Vs Repainting It?

Without alarming you, a typical roof replacement will cost around 3 to 4 times more than repainting it, but sometimes with difficult access considerations this may be even higher. See what’s it cost to repaint my roof.

Does Any Particular Paint Last Longer on Roofs?

Um… short answer… YES! The long answer though… A good grade paint will outlast others by 50% in colourfast and durability. Most of the main brands have high performers that maintain gloss which helps reflect the heat and lower the impact UV has on the coating. Our team of friendly professionals are more than happy to discuss the brands and colours we offer, so just ask their thoughts.

How Long Does a New Roof Last in Comparison to a Repainted Roof?

Of course, as with any products a brand-new product will have a warranty and life expectancy that is longer than something that is re-conditioned. This does not mean that going brand new is going to be the better option. While a brand-new roof has a warranty of 10-15 years depending on proximity to the sea, you can expect to renew its paint work within 15-20 years. Whereas a re-painted roof can expect to be recoated within 8-12 years.

So, Can It Be Painted Over?

There is no problem with painting over top of the existing roof provided that the right preparation and primers are applied. So, in summary, repainting can be a cost-effective and relatively quick option for rejuvenating your commercial roof providing the roof is in sound condition.
