If you like reading or watching a good thriller you expect to be kept guessing through the twists and turns until in the end and it’s all a surprise.
Old pergolas can be a bit like this too with repairs, patches on patches for a quick fix, a fresh lick of paint. You never quite know what your old pergola could be hiding especially if it was already there when you bought your home until you remove the old pergola to see a nasty surprise.
Old timber pergola that has been patched up and repaired over the years
In the Perth area there are a lot of homes that still have old timber pergolas on the back of their homes. Some of these have stood the test of time, some are just barely hanging on making them a danger to you the home owner, your family and your home.
A lot of these timber pergolas were originally covered with shade cloth only to be replaced with either fiberglass roof sheets or steel roof sheets. Some may have had gutters and down pipes added and then there are those that have been partly or fully enclosed.
A damaged timber pergola that could be a danger to your family and your home
More recently Great Aussie Patios has been replacing older steel patios that have seen many years of use and abuse and like the wooden pergolas these too can hide issues or damage to the house fascia, guttering and downpipes.
It can be hard to notice problem areas to the untrained eye, however our sales team at Great Aussie Patios takes special care when looking at replacing an old pergola when quoting for a new patio.
We are often called out to provide a quote due to the old patio falling apart or leaking, however the leaking could be hidden damage that until the old pergola is removed has not been noticed.
One of the most common issues with wooden pergolas is wet rot. With years of soaking up rain like a sponge the timber swells or grows. It allows fungal spores to grow which over time make the timber loose its strength and eventually collapse.
Even those pergolas that have had the shade cloth removed and replaced at some stage with a solid roof sheet still run this risk of wet rot due to many years of exposure to the elements prior to the solid roof being installed.
Notice the wet rot in the structural edge beams causing them to loose their rigidity and sag
A lot of wooden pergolas were painted but over time the paint wears away exposing the wood, it will soak up the moister and retain it. When this is next to your house fascia or guttering were the patio meets the home it can cause rusting issues to these areas but is hidden away and not always noticeable.
This constant wet wood against the steel of the house fascia and guttering will eventually find a weak spot and attack the area causing rust. This in most cases remains isolated to the one spot however rust can spread quite easily and time is all it needs.
Notice the dirt and old tree debris sitting behind the timber beam in front of fascia and staining to the eves, this is a sign of hidden damage
There are signs of rust on the house gutter which could mean that the existing house gutter will need to be replaced along this section
If however you have an old steel carport or patio then the most common issue would be rust. Like kryptonite to Superman rust is to steel. Rust will eventually find its way into a steel patio, all it needs is a small exposed area to take hold.
Many years of dust, dirt and grime finding its way between steel beams against the house fascia and guttering lead to moister build up. This moister is retained for some time as it will not dry out or takes longer to dry out.
Once rust has set in it quickly begins to eat away the steel causing the steel to break down. This can have a devastating effect on your house guttering and fascia that will need to be replaced along with the old steel pergola.

The effects of rust are even greater as you get closer to the coast as the wind carries salt from the ocean and deposits it on your old steel pergola.
