In average, the house needs roof replacement in Sydney after 20 years of being subjected to sun, rain, snow and other elements. If your house is located in an area where the weather is extreme then you might need to replace it sooner.
Remodelling magazine reported that you will need $20,664 in the United States if your asphalt shingle rood needs replacement. This material is the most common in residential properties in the country. This is based on national costs considering that the roof is midrange and spanning only 3,000 square foot. The cost already covers he vented ridge and skylights.
This number is not fixed because there are many factors that should be considered such as the location, the size of the roof, the materials to be used as well as how complex the roof type is.
For the materials, there are things to be considered such as shingles, protective coatings, underlayment, flashing, drip edge and many others. For the labour, you need to hire a skilled worker that knows how to remove the old roof and replace it with the new one. Disposal should also be considered because the old materials removed can either be thrown away or recycled.
Todd Miller who is the president of a roofing manufacturer said that asphalt shingles can cost between $3 and $5 for every square feet. Higher quality materials such as slate, tile and metals can cost between $9 and $15 for every square feet.
Roofing can be quite expensive especially if the roof is large or it has a complex structure. The biggest cost went to the labour especially if installation is done by a professional. Labouris between 40 and 50 per cent of the entire cost according to Miller.
