When Do You Need A Roof Replacement

How to Install Roof Shingles | Ask This Old House

If youre unsure whether your roof needs a restoration or a replacement, it can be a good idea to get a professional builder, building inspector or roof restorer to carry out an inspection and give their expert opinion. For example, Mr Hannam noted that it can often be better to replace, rather than restore, sheet metal roofs and some older tiled roofs.

A lot of the time, some of the very older tiled roofs are not worth restoring because, for example, certain designs are less sufficient in keeping moisture out, he said.

We generally recommend replacing rather than restoring sheet metal roofs because a good quality sheet metal replacement can last you 40 years, whereas a restoration is only as good as the paint youre putting on it.

The decision as to whether or not you need to get your roof restored may come down to a couple of factors, including if there are any structural or physical defects that need fixing or if it you just want to improve the look of the roof. Repairs may be unavoidable, while cosmetic alterations are a matter of personal choice. It could be a good idea, if you are in doubt, to get a few opinions .

Cost Of Roof Inspection

Having a roof inspection done helps to identify potential issues, provides solutions on what needs fixing, determines the condition and lifespan of your roof, and can help you keep your roof in good condition. As previously mentioned, its recommended that you have an inspection done twice a year, or after a major storm, to help you get ahead of problems before they become large or expensive.

Not to mention, a roof inspection will help determine whether your roof sheathing is damaged, rotted, and needs to be replaced. The average cost for a roof inspection is between $100 and $600, with most homeowners paying around $350 for both an internal and external inspection on a 1,500 square foot sloped roof. The actual price that you pay for a roof inspection varies based on the size, material, pitch, and condition of your roof.

Removing Old Roofing Vs Roofing

Belair Re

In most states, you can have up to two layers of asphalt shingles installed on your roof. Roofing-over, or putting one layer of shingles over another, can save you significant amounts of money on your new roof because you avoid the labor involved in removing the old shingles. Roofing-over does not have tear-off costs, lowering the projects cost by $1 to $2 a square foot. However, only asphalt shingles and some types of standing-seam metal can be used to roof over an existing set of asphalt shingles. This makes the cost range from $6,000 to $8,000 to roof-over most 2,000 sq.ft. homes.

Roofing-over presents some issues, however. Putting one layer of shingles on top of another or putting metal panels over existing shingles does not address potential underlying issues with your deck or underlayment. It also doubles the thickness of your roof and means the new shingles may not lay as flat. This can result in the new shingles lifting off more easily, which can cause the new shingles to deteriorate more rapidly if the underlying shingles have moisture problems. The next project will require a full replacement much sooner than if you had done it all at once the first time.

What Is The Cost Of Painting A Colorbond Roof

The cost of professionally painting a Colorbond roof ranges from $50 to $70 an hour inclusive of GST. Your roof painter will also charge for any necessary prep work and cleaning.

Why does painting Colorbond cost up to $70 an hour? First, the painter washes the surfaces to be painted with water and detergent followed by a rinse with clean water to remove any residues, grease, or dirt that may have accumulated on the steel.

Then the painter needs to sand the Colorbond to ensure good adhesion of the paint. This step does not remove the protective zinc coating added to the Colorbond at the factory, because the heat in the galvanizing vat, about 425° C, is hot enough that the zinc and steel form a layer of alloy that goes into the steel itself. It only takes a little scuffing up of the baked-on paint on the Colorbond to ensure good adhesion of the new coat of paint.

Depending on what paint is used to paint your Colorbond, the painter may need to apply a primer, or just use a single coat of a self-priming acrylic. Then the painter applies top coats.

Regular corrugated steel is fine for building a shed or a detached garage. It lacks the aesthetic appeal of Colorbond, but as long as it is galvanized steel, there is no risk of its becoming a rusty eyesore.

Powder-coated Colorbond is an appropriate choice for most houses. Powder-coated Colorbond starts as raw steel. Then it is dipped in a vat of molten zinc to form a protective layer to fight rust and corrosion. Next is it sprayed with powder that bakes color onto the galvanized steel for colors that wont fade for a decade or more.

Double-sided Colorbond has color baked onto the steel on both sides. It is the steel of choice when you are going to see both sides of the panel, from the curb looking onto your roof, and from your living space under a pergola or on your deck or patio. The second layer of durable color costs a little more.

Colorbond Ultra is the roofing material of choice for seaside homes. Even galvanized steel eventually wears out when it is constantly exposed to salt spray, but a third layer of protective coatings adds decades of life to roofs even in seaside settings.

Prices of Colorbond are subject to change. Its always a good idea to get a current quote from a roofing professional such as ELR Plumbing.
