Architectural shingles are the most common type of roofing materials due to low price and relatively easy installation process. Three-tab asphalt shingles is a cheaper option, but because they usually don’t last long and have to be replaced in 10 – 20 years it might not be the best solution. Natural or synthetic slate more expensive, but superior performance, rich look and longer lifespan make slate one of the best roofing product for luxury custom build homes. Concrete or ceramic tile the most durable materials, but the cost of such roof will be extremely high. Cedar shingles and shakes are not cheap, but still an affordable option.

Always count additional essential materials which have to be purchased for a roof installation including roof flashing, felt paper or roof underlayment, galvanized steel vents and nails.

Determining labor cost for a roof replacement labor-cost

Cost of man power will depend on work complexity, a type of roofing materials and installer’s hourly rate. Removing one layer of old asphalt shingles from a low pitch roof and installing new will be estimated at minimum charge. If building codes allows and the roof structure able to support the weight of a few layers of shingles the new roof can be installed over existing one what will significantly decrease labor expenses. Installing metal tiles or slate less affordable and some roofing materials including concrete or ceramic tile will cost a few times more comparing to architectural shingles.

Replacement cost will greatly depend on pitch and a roof design. Roofing contractor will calculate high pitch roofs with multiple dormers and complex design at significantly higher rate per each square comparing to a simple hip roof with low to medium pitch.

Preparation work including replacing rotten wood, reinforcing rafters or fixing the whole roof structure will lead to extra charges. There are also additional fees will be present on invoice from a roofing contractor for ordering dumpster(s) or hauling away old roofing materials.

Shopping for new roofing material shopping

Normally companies specialized in a roof installation, replacement and repair will offer products they normally install and a homeowner can easy choose desired materials, style and color of a new roof from options available. On a low budget shop for inexpensive materials which have limited design options and can be bought from the shelf of local home improvement retailers. Prepare to wait from couple to a few weeks for delivery if ordering stylish products.

Estimating replacement time estimating-time

Roofing company should be able to complete 30 squares of asphalt shingles replacement in about two work days. It will include tearing off old shingles, installing new and cleaning a job site. More time will be necessary to replace a wooden roof. Installing slate or heavy concrete tile is more time consuming process. Weather conditions will impact time frame for a roof replacement. If there are no signs of rain a roofing crew might work regular work hours and finish the project in a few days. But if there are only one or two days will be a good weather, but the roof has to be done before the rain season a contractor will push the work by involving more man power as well as extend work hours to complete the roof faster.

Roof replacement is not a do it yourself project and it is better to hire a roofing company not a handymen with couple helpers to perform such work. Poor installed roof will cause leaking and damaging not only home interior, but the whole structure of a house. Hiring professional roofers will ensure work quality and adequate roof performance.
