While homeowners are usually advised to get quite a few roofing bids and then take the best one, it can be a difficult decision when you have no idea what goes into putting a new roof on a home or building.

It can be exasperating trying to choose a roofing contractor when you have no idea what is a fair price. In order to understand how roofing costs are determined, you must first understand the process and materials that go into re-roofing a home.

Cost of Roofing Per Square Footage

The roofing company must first measure the roof so that the correct amount of roofing supplies can be figured into the bid. The sum of the square footage is then divided by 100, which provides the amount of roofing squares required to complete the job. Normally, three to five bundles of roofing covering are needed per each square.

Structure of the Roof

Roofs that are steep and oddly shaped require much more exertion than standard pitched roofs. While roofs with a lot of angles and flat surfaces are equally more difficult and involve extra materials than the ones with a modest back and front gable.

The Cost of Roofing Materials

Your choice of shingles, shakes or tiles plays a big role in the cost of a new roof. Shingles are the least expensive, while high-grade tile roofing is made of a concrete substance and can be very costly. No matter what main roofing material you choose, all roofs require a felt underlayment beneath the top roof covering. The amount of rolls needed will be included in the estimate. Other supplies such as vents, nails, pipe jacks, staples, glue and flashing can add up to as much as 25% of the overall materials costs.

Labor Costs for Roofing

All labor costs are taken into consideration when a roof contracting company makes out an estimate. The assessment will include more than just the reroofing labor and supplies; it will also include any structural damage repair, loading, hauling, and cleaning fees. The disposal fees for old tiles, roofing shingles, shakes and other materials can be very expensive.

You must also take into consideration that expert roofing installers are paid higher wages because they are certified, and the company guarantees their work. Reputable roofing businesses also pay the costs of providing accident insurance coverage on their workers so that homeowners are not liable. Hiring a reputable company also ensures that they will be around in case any problem should arise.

While it is often tempting to accept the lowest bid, it’s usually not the right choice. Always keep in mind that you get what you pay for. If you get a leak in a couple of years and the company is no longer around, you will wish you had not chosen the lowest priced company. The best roofing contractor to hire is the one that offers all of the above in a timely manner for a fair price and warranties their work.
