CAN YOU PAINT OVER PREVIOUSLY PAINTED TIN OR TILE ROOFS?

The short answer is yes and the long answer is:

If a roof has been painted before, irrespective of whether it’s tin or tile, we certainly can re-paint the roof, but it’s a matter of knowing that the paint applied is only as good as the paint that’s left after it’s cleaned. When we prepare via pressure cleaning a roof for re-sealing and painting we tend to like using at least 4000psi or more of pressure and 15-21L per minute flow rate, especially well with a previously painted roof – in order to hit the mould and dirt as hard as is practical. The common-sense theory is that if there’s paint or sealant left on the tile or tin after it’s been cleaned at high pressure and sometimes at high heat (if hot water pressure cleaning is required), then it’s good enough to re-paint. Only when there’s constantly flaking paint does the home owner run into more expense – where sometimes it’s just easier and better to replace part or all of the roof.

There’s several different sealers on the market that can ensure a great seal on the tile or tin. Tin roofs require a sealer that dust’s on and dries really really well, allowing the coloured paint the best chance of adhesion. Like all painting with spray devices, you’re always better off applying less paint than more, but increasing the number of coats applied. Tiled roofs are quite different and require a building-up process – whereby a thicker sealant can be applied more liberally with the security of usually having quite a porous and ideal surface for applying it.

Roof painting is about adherence, as it is about quality and durability of the paint being used. At Full Circle we endeavour to use the best quality materials available, with an accent on finding roof paints that are as hard as possible. The hardness of paint is a very big determining factor in whether dust (which turns into mould) and or other foliage will slide off the roof and away from the surface. Also, a harder paint just tends to do better with UV and doesn’t tend to turn chalky as fast either. More will be shared in a following blog about the quality roof paints sourced.

ROOF RESTORATION OR ROOF PAINTING?

ROOF RESTORATION OR ROOF PAINTING?

Having a sound roof is foundational to a healthy home. Often, we get calls from people around the northern rivers, looking to start a whole gamete of work around their home (be it a maintenance boost or full blown renovation) who want to start with their roof. It makes sense starting from the top and working your way down, for without a waterproof roof, that’s been restored and or painted, the rest of the home isn’t fully protected.

As the name of this blog implies – there are two distinct types of roof jobs that we at Full Circle Refinishing see. Asked to pressure clean many roofs in the northern rivers, often the conversation will turn into whether we can quote to repair and re-paint too. Roof restoration is a complete overhaul of a tiled or tin roof, at a much greater cost than simply painting, which is what we offer. In many cases though, often with tin roofs, if all seams, screws and calking is in good condition, a paint can be all that’s required.

Keeping in mind the old saying – there’s the right tool for every job, at Full Circle Refinishing we work in with partner roofing companies that specialise in roof repair. When we’re asked about repairs and or roof restoration, we’re able to get a very good idea of what’s required and include that in a roof restoration quote to then subcontract to our roofers prior to paint. Alternatively, we can have one of our roofing partners work with you directly if it’s deemed best, especially when significant restoration work is required prior to painting – such as replacement or structural work. We don’t really mind so long as at the end of the day a reputable, insured and licensed roofer does the correct repairs with the next decade or two in mind!

So, the long and the short is: when considering re-painting your roof, know that investing in the required pointing, tile changes, structural work, screw replacement, flashing and or other items is really mandatory for a successful and long lasting roof. Always feel free to call and ask questions, get a quote or ask for our trade partners; we’re here to support you with these items. Enjoy choosing that new roof colour!

SIMPLE TIMBER AND DECK MAINTENANCE

Here at Full Circle Refinishing, we endeavour to make all deck restorations as simple as possible. Often you have spent many hours and thousands of dollars preparing and oiling decks and balustrades in the years prior to our arrival – sometimes we can and sometimes we can’t capitalise on that. There are three main ways we’ll attack a timber deck restoration job:

1. STRIP JOB: it’s a full stripping away of the old coating
Where to throw good money after bad (overcoating a badly weathered surface) isn’t what anyone wants to do. This is sometimes best achieved using a chemical stripper applied like a paint over the old coating and then pressure cleaned off (using hot water if it’s particularly hard to get off). At other times, we’ll sand old coatings back to bare wood. There’s several things we have to look at before deciding which route to take – such as, if using stripper and a pressure cleaner, is the timber strong enough to hold together or will it become grainy and prematurely wear, plus other substrates nearby that we have to be careful not to ruin. If sanding, we’ll have to decide whether raised nails or screws are too problematic or if the boards are badly cupped, or too thin – in this case we will lose too much timber in the process. Following whichever method is most suitable to the timber deck restoration process, we’ll work with you to decide which timber oil best suits you needs and preferences and then apply usually at least two coats.

2. PRO-CLEAN: A professional clean can sometimes do the trick
We’ll apply a strong chemical cleaner to old and weathered timber decks to restore the colour and remove dark mould patches that deteriorate wood and aren’t pleasing to the eye. When restoring timber in this way, we have to be mindful of the fact that this professional cleaning (done with one of several timber brightening chemicals to choose from) that when pressure cleaned off, may not leave an absolutely perfect surface to re-oil. If a client is after ‘bang-for-buck’ so-to-speak, then this process is often a fantastic option, for it provides the foundation to lay coats of oil over previously coated timber and avoids the cost of having to start again as with a strip job detailed above. A light sand is required after such a clean and then one or two coats of oil can be applied to finish.

3. QUICK-CLEAN & SCUFF: Quick cleaning and or light sanding
For the home owner who has done quite well with their timber deck maintenance, a less powerful timber soap and pressure clean plus usually a light sand using a pole sander with 120 grit sandpaper, can often be enough to clean and rough the surface ready for a re-coat. This process is faster than the above and very much the desired annual timber deck restoration, or more accurately, timber maintenance routine, that we encourage all home owners to have in place. What’s great about just quickly scuffing or cleaning a timber deck is that it doesn’t cause really any wear and tear to the timber beneath the coating – the asset we are endeavouring to extend the life of in all cases after all. Usually only one coat of decking oil is required to suitably protect the deck until next year. So, like in most cases, prevention is better than a cure when it comes to timber deck restoration and maintenance schedules.
