Common Roof Problems


Locating a leak

The first challenge is to locate the source of the leak unless you have had considerable experience in the roofing industry, a leak may be difficult to locate, and the causes fully understood. In an effort to save your investment we have compiled a list of the 9 most common Causes of Roof Leaks and how they happen.

1   Blocked Gutters, Valleys and Down Pipes.
Blocked gutters and downpipes can result in water that stands for hours, or longer, blocking the flow of water from the roof.  This can leak into ceiling cavities the results can be serious: and you could end up with structural damage.  Build-up of leaf matter, debris in valleys can cause backflow into the roof cavity
Causes: Leaf and tree debris, toys, moss and lichen, sagging and cracked joins in the gutters preventing the flow of water, poorly installed.

2   Broken or misaligned Tiles/Caps
Whether it be a broken water channel or broken tiles this will affect the distribution of water and allowing it to enter your roof space and wet your ceilings.
Causes: Walking on roof carelessly, falling debris, having work done on roof (Electronical, Foxtel, Solar Panel installation). Unprofessional installation, wrong tiles type used for replacements, rotten or sagging battens.

3   Rust
Rusted gutters, valleys, Iron sheets including Colorbond, flashings and even tek screws. Can cause cracks and holes to form allowing water to leak through.
Causes: Age, sitting water and untreated metal.

4   Broken, cracked and missing Pointing
Your old pointing may have deteriorated and started crumbling leaving the joins on the ridge caps exposed.
Causes: Age, poor quality material.

5   Fretted Tiles
Clay tiles are eaten away from underneath and can be hard to spot.
Causes: Proximity to the coast, age, salt, chlorinated or hardened water on the roof.

6   Weep Holes
A small drainage hole installed in the pointing is sometimes blocked.  Water builds up under the capping and will drip after long periods of rain.
Causes: Getting pointed over, silicon, lichen, moss.

7   Vents, Chimneys, skylights, Dutch gables and other roof protrusions.
Seals may deteriorate over time resulting in water seepage into roof cavity, look for cracked rubber around the plumbing pips.
Cause: Poor installation, age, rust, leaf litter/debris, cracked lead flashing or seal, exposure to the weather and harsh Australian UV rays.

8   Flashings
Flashing are thin pieces of metal that are installed under tiles and on the joints of your roof in order to create a water-resistant barrier.  A hairline crack above the flashing can allow vast amounts of water to run behind the flashings.
Causes: Wear and tear can cause flashings to split, rust or flashing pulled away from walls.

9   Skillions
Roofs tiles which are very dependent on their water courses do not like skillion pitched roofs.
Cause: Lack of pitch of force water off the roof and/or holes and tears in waterproof sarking.

Roof Restoration Perth – Reviews

Reviews for roof restoration companies in Perth may help in choosing the right company.

Roof restoration is costly and trying to choose the best company to do the job can be very daunting as most people are aware that there are some unscrupulous operators out there that may not complete the work properly.

A good place to start is by making sure it is a registered Roof Restoration Business. The business should display their Painters Registration Number and their ABN number on their website, you would normally find this on the About Us page or the Contact page of the website.

Next look at the backing that the business has to be able to honour their warranty.

So let’s look at warranties and what they mean. The warranties for roof restoration and coating here in Perth varies immensely with some companies offering a 10 – year warranty and others a 20 – year warranty. 
So what’s the reason for the huge difference? Some companies may have a warranty that only covers a small amount of full warranty.
Like it may be say a 20 – year warranty but only say 3 – years full warranty and then 17 – years of a pro rata warranty. This means after three years you will have to pay an elected portion of any warranty claims this is probably not what you want.

Is the company going to be able to back their warranty?  This is what the WA Government Building Commission has to say about it.

“Before you sign anything, read and make sure you understand all the small print including anything

printed on the back of a work agreement or order form.

Look very closely at long-term “guarantees”. These may sound appealing but ask yourself how much

they would be worth if the trader should sell or go out of business.  Check exactly what the small print in the guarantee actually covers – sometimes it can be almost worthless after a short period.”

So how do you protect yourself from this?
Some professional operators use a superior product being Dulux. Now Dulux is the is the largest and most trusted paint brand in the country and if you are a Dulux Accredited Applicator as Platinum Roof Coating are then Dulux has the confidence in them to guarantee Platinum Roof Coating’s full warranty.

So no matter what happens you are covered and knowing that Dulux has that sort of confidence in this company you know you are dealing with true professionals.

I hope this review has helped.
