New roofing costs vary, depending on labor and materials. If your contractor has to remove your old roof and any layers underneath it, your labor costs may be higher. If you choose a tile or wooden shingled roof, difficult installation can increase your costs. If supporting structures require repair, additional material and labor expenses may be incurred. The shingle material you choose will also affect your costs. Asphalt and composite shingles tend to be the most affordable options for sloped roofs. Hand split wooden shakes and tile shingles may be more expensive due to production costs. If you choose heavy shale or tile for your roof, you may need to add structural support. In many cases, size determines the amount of material and the installation time needed. Larger roofs tend to be more expensive. Getting several bids can allow you to compare roofing expenses. Evaluate the roofing process recommendations. Cost may be more for a supervisor on site during the roofing job. The bid may be less for re-roofing instead of replacing your roof.
