How do I know if my roof has a leak or crack?
If you have water stains that extend across ceilings on run down walls, you more than likely have a roof leak. Tracking down the leak is the hard part whilst the fixes are usually easy. Minor leaks can cause major damage so if you detect a leak in your roof, it is best to fix it immediately as even over a short time, small leaks can led to big problems, such as mould, rotted framing and sheathing, destroyed insulation and damaged ceilings.
What style roof should I choose for my house?
Whether you are building from scratch or choosing a new roof for your existing home, a wide range of materials are readily available and worthy of consideration. These materials consist of: asphalt, wood and composite shingles, as well as slate, metal, concrete and clay tiles. If you are remodeling or installing a new roof, your new roof will depend on your choice of roofing material. Should you be considering other options, you'll want to consider not only the cost but the colour, texture, weight, and durability of your selection as well as what traditionally have been used on houses like yours.
How is Colorbond steel made?
“Colorbond starts with a 'Zincalume' steel base. Zincalume steel has an aluminium/zinc/magnesium; alloy coating that delivers outstanding anti-corrosion performance.
Then they apply a conversion layer to the surface to steel to improve adhesion.
Then a polyester primer is baked onto the surface.
Finally a top coat is applied consisting of a specially developed, exterior grade paint that is baked on to ensure maximum resistance to chipping, peeling and cracking.”
How are concrete tiles made?
Concrete tiles are made from sand, water, cement and pigments, and are not fried like clay tiles, but cured at temperatures of approximately 60 degrees Celsius. The curing process makes them sturdy enough to be transported and laid within a few days of manufacture, and they get stronger over time.
Terracotta Roof tiles facts:
Tiles made from terracotta are a very commonly used roofing material in Australia and around the world. Terracotta tiles have been around for a very long time and either appear in their distinctive, natural red-orange colour, or glazed to provide different finishes and colours.
Terracotta tiles are installed by placing overlapping and interlocking rows of tile on the roof and are available in a range of styles.
Terracotta is very hardy and has been known to last hundreds of years if it's treated right. Terracotta is also waterproof and fire resistant, offering good protection from the elements.
Slate Roof Facts:
Slate is a type of metamorphic rock, meaning a form of existing rock which has undergone transformation due to intense heat and pressure. It is a fine grained, frequently grey coloured rock however, slate occurs in a variety of colours even from a single locality. For example, slate from North Wales can be found in many shades of grey from pale to dark and it may also be purple, green or cyan.
Slate is laid on the battens in a 'brick bond' pattern, i.e. with the joints between them aligned with the center of the slates above and below, and with about 3mm between the sides. This layout gives a double lap covering which means that the top part of each slate is covered by two slates, the center of the slate of the next row and the lower part of the slate above that. The overlap will depend upon the slope of the roof - the steeper the slope, the smaller the overlap required.
How is asphalt shingles made?
In the United States, asphalt shingles are categorized as either organic-based or fiberglass-based. Organic-based asphalt shingles are manufactured with a base made of various cellulose fibers such as recycled waste paper and wood fibers.
How do I determine if a roof should be replaced?
In time, every roof needs to be replaced, usually due to the long term effects of weathering. If a residential roof is more than 20 years old, it is a prime candidate for re-roofing. Ways to insure your roof needs replacing include:
Look for things on the inside such as places where the roof deck is sagging, signs of water damage or leaking, dark spots and trails and outside light showing through the roof.
On the exterior on the rood, pay attention to such things as damaged flashing, missing shingles, curling, blistering, buckling, and rotting and algae growth.
Visually inspect your roof for cracked torn, bald or missing shingles.
Scan the roof for loose material or wear around chimneys, vents, pipes or other penetrations.
Watch out for an excessive amount of shingle granules (they look like large grains of sand) in the gutters - this is a sign of advanced wear.
Check for signs of moisture, rot or mould. Even if wet spots are not always directly under your faulty shingle; water can travel down to its lowest spot before it drips. Mould, fungi and bacteria can grow quickly - within 24-48 hours of a water-related problem
Examine the drainage, and make sure gutters and downspouts are securely attached. Also ensure all drains are open and allow water to exit, and all gutters and downspouts are free of debris.
Check that all bath, kitchen and dryer vents go entirely outside of your home, not just into the attic.
Metal roofing facts:
Non-metal roofing material begins to deteriorate as soon as it's exposed to elements such as the UV rays of the sun, temperate changes, severe storms and high winds. A metal roof will never deteriorate and can withstand most everything Mother Nature throws its way.
Metal roofs will not increase the likelihood of lightning striking your home; however if your home were hit by lighting, your metal roof would disperse the energy safely throughout the structure. Since metal roofing isn't combustible or flammable, it is a low risk and desirable roofing option where severe weather is concerned, especially for lightening.
Today's metal roofing systems are built to last. Steel metal roofing has a 'metallic coating' made of either zinc or a combination of zinc and aluminium. This metallic coating prevents rust from forming and is bonded to the steel at the factory. Paint is then applied over the metallic coating to provide the long-lasting colour home-owners desire.
In most cases, a metal roof can withstand decades of abuse from extreme weather like hail, high winds and heavy snow. A typical hail storm will not dent your metal roof.
Should I replace or restore my roof?
This is a common question and mainly depends of two factors: How bad the existing roof is and your budget. The only way to know how bad the roof really is is to get an un-biased professional opinion some companies only do roof replacements so they will only try to sell you a new roof. Some only do restorations and will tell you can get 20 years more out of your roof when actually it is best to replace it now. One important thing to remember is that the longer you leave your roof, the more likely is it that water will get into places that it shouldn't.
How does heat reflective paint work?
Heat reflective paint works by reflecting the suns energy before it can hit the roofing material - somewhat like a reflective shade for your roof. This basically means that your roof is cooler, meaning your roof space is cooler which in turn keeps your house cooler. There is a lot of technical information and test results available from reflective suppliers online or in your local hardware store.
How much will I save on my electricity bill if using heat reflective paint?
A normal household can save at least 50% of their air conditioning power bills as they will tend to use the Air conditioner a lot less. Some customers have reported no longer needing to use their air conditioner at all, but a lot depends on your specific location and building type among other things to consider.
If I have a fibro/asbestos roof, should I get it replaced?
If your fibro/asbestos roof is in good repair, there is no need to have it replaced as it does not pose a safety risk. However, it it's leaking then it means there is damage and it requires repair.
Is insulating my new roof a good idea?
Yes, there are numerous reasons why installing insulation at the same time as replacing your roof is a good idea. Firstly, insulation usually makes a significant difference to the comfort level of people homes as it keeps your house up to 10 degrees warmer in winter and up to 7 degrees cooler in the summer which will obviously lower your heating and air-conditioning costs.
Are all gutter guards pretty much the same?
Not all gutter guards are the same. Some types are noticeably inferior, such as the fiberglass (fly wire mesh) and gutter guards that are installed inside the gutter itself.
Is installing gutter guard a wise investment?
If your home is located in a leafy area - then most definitely. Installing gutter guard is smart preventative maintenance, stopping leaves clogging up your gutters and down pipes, thereby reducing the risk of expensive flood damage in heavy storms. Leaf matter sitting within the gutter can also cause damage it increases the chances of the gutter rusting out. It is important to note that gutter guard is not completely maintenance free.
There will be times when some lead matter can build up on top of the gutter guard mesh particularly in wet weather. Generally the majority will blow off but on occasion it will require removal using a broom a blower vacuum. However, your gutters will remain clean and debris free.
