Valley iron replacements refer to the process of replacing or repairing the valley irons on a roof. Valleys are V-shaped areas where two roof sections meet, forming a junction. Valley irons, also known as valley flashings or valley metal, are typically made of metal and are installed in these valleys to provide added protection… Read More
To fix broken tiles on your roof, start by wearing protective gear. Remove debris, pry the broken tile, replace it with a new one of similar size and shape and secure it with roofing cement. Check placement and cement hold. Call a professional if you’re uncomfortable or the damage is extensive… Read More
It is imperative that the metal sealing strip, which is currently composed of lead, undergoes some form of intervention in order to remedy its current state. This intervention can potentially take the form of either a repair or a replacement of the metal strip. It is crucial to address this issue as the current state of the strip can have negative implications on the overall functionality of the system in which it operates… Read More

When it comes to maintaining the integrity of your roof, it’s crucial to check periodically for any potential damage. One of the common areas that can become problematic is the top of your roof where the ridge runs along. This section is referred to as “ridging” or “ridge capping”. It may seem like a small part of your roof, .. Read More

To replace the valley iron also called Valley gutter the roofing feeding down into that gutter needs to be removed.
So the roof tiles need to be stripped from over it including the ridge capping at the top. After the removal of the old rusty Valley iron, the new valley iron can be supplied and fitted into place and then the roof tiles fitted back along the valley lines along with the ridge capping re-bed and point.
If there is Colorbond sheeting feeding down into the valley those sheets need to be removed and refitted along with ridge capping also which is a much bigger job.
Replacing roof tiles can be easy or hard. Generally it’s hard to get the same coloured roof tile to match the rest of the roof so it’s best to find a place on the roof that won’t be seen and used tiles from that area to replace broken tiles and then fill in the unseen area with the new roof tiles.
Some roof tiles are no longer available to buy new or the profile may be available but the colour is discontinued.
There is often a name on the bottom of the roof tile which helps to identify it. Also measuring the cover sideways and length of the tile WITHOUT the overlap will assist in getting the right size.
We are able to source all equivalent roof tiles to repair any roof 99.9% of the time.
Another factor affecting the replacement of roof tiles is whether they are situated very close to, or under ridge capping bedding and pointing. If they are, this may necessitate repairs to the ridge capping as well as replacing the broken tile.
The last factor is the pitch of the roof and the grip on the surface of the tile. Accessing a steep or slippery roof requires much more work.
Lead flashing is always onto roof tiles. It is not for flashing onto any metal roofing since there is a corrosive effect of the two metals reacting with each other and causing rust in the roof sheets.
Lead flashing has been upgraded over the years. When I started in 1981 it was always 10 kilos per square metre which after a couple of decades increase to 15 kilos per square metre and is now 20 kilos per square metre.
An issue I have found with it is typically on a Dutch gable where the carpenters have rolled out a 6 m long roll of lead and used it continuously with no overlaps.
Australian standards stipulate short lengths of lead with an overlap enabling expansion and contraction to take place without buckling the lead and causing it to eventually crack.
20kg/m lead couples worth the short lengths is fine. I recommend painting the lead to eliminate any of it going into the rain water.
On a dutch gable the barge boards are typically in a very poor state and also need to be replaced and of course the bedding and pointing on the edge of the roof tiles will need to be redone.
Where the lead flashing goes under wall boards then those boards will need to be removed first to be able to replace the lead flashing. Timber blocking should be installed so as to enable additional fixing points for the lead.
We have developed a technique to enable us to be able to reinforce one edge of the lead which goes under the wall boards and can be fixed onto the wall studs through that reinforcement.
We get a lot of jobs where a patio cover has been added onto the back of the house and attached to the fascia board underneath the original guttering.
The top edge of that patio cover will be sealed off begins to the timber fascia with silicone and usually minimal or no preparation of the surface. Any water flowing down the fascia from the back of the gutter when it overflows will run in the back of the patio cover and drip off the fascia which is now inside the patio cover.
To make good, the bottom row of tiles needs to be removed along with the original gutter and a flashing added to eliminate the leak along that patio cover to the fascia point. Also if the original gutter overflows the flashing will prevent that overflow from ingressing the interior.
Ridge capping is fixed onto roof tiles firstly with sand and cement bedding mortar and finished with an acrylic-based pointing admixture.
Over time there will be some cracking in particular with the old style pointing which was sand, cement and oxide colouring. Acrylic-based Pointing used these days has some flexibility to it to prevent cracking and is on the whole successful but not 100%.
A proper repointing job requires good preparation for the new pointing to stick properly and not peel off.
Water finds millions of ways to leak into your roof, the primary reason being capillary action.
There are many traps for young players in performing roof installations and our work is primarily fixing the mistakes.
As an experienced roof repair specialist where are able to assess and diagnose leaking efficiently and effectively. Some businesses operate on the business model of replacing the whole roof to fix a leak. The price advantage of actually fixing the leak without replacing the whole roof is obvious.
