Should I paint my roof or replace it?

Clients often ask should I repaint my roof or replace it. This depends on the following factors;

What is the current condition of your roof? St Kevins Roof

Is it rusty, has it got holes or is it just flaking badly?  Any paint professional will be able assess the flakes and help you decide best course of action. Often flashings rust outfirst so just replacing these is a good option at a fraction of the cost of a new roof.

 What will be involved in repainting it?

Typically a older roof needs to have a moss treatment followed by waterblasting. Blasting is not about high pressure but rather water direction and spin in the nozzle to drive loose paint off before recoating the roof. Spot priming is the next factor before recoating the whole roof with two good coats of high quality roof paint.

Does any particular paint last longer on roofs?

The answer is yes. 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. Discuss the best products with a paint professional.

What is the cost of a new roof vs repainting it?

Typically replacing a roof will cost around 3 times more than repainting it but sometimes with difficult access considerations this may be even higher.

 How long does a new roof last in comparison with repainted roof?

A new roof has a warranty of 10-15 years depending on proximity to the sea and we see them needing to be recoated after around 15 to 20 years. A painted roof will need to be recoated after 8-12 years.

So can  be painted over?

There is no problem with painting over top of existing coloursteel provided that the right preparation and primers are applied.

So in summary, repainting roofs is a very cost effective way to lengthen the lifespan of your roof. Providing the roof is in sound condition, repainting it will give you many years of hassle free running at a fraction of the cost of full replacement.
