Roofs are subject to constant stress. Sunlight, high winds, snow, heavy rains and stormy weather are all responsible for a gradual deterioration in your roof. At one point you might need to take a decision on whether you need to re-roof or replace the roof altogether. Calling in an expert roofer might help. Replacement is a costly venture that can be avoided if the repairs are done by professional roofer contractors. Repairs are less costly and time saving. If the condition of the roof deck is fine, you may not have to replace the whole structure. When you are thinking of replacing the entire roof, you have to allocate funds and time to the project. You also have to think about disposing of the existing shingles and other structures that constitute your roof. It’s an expensive and stressful task. Re-roofing might seem a cheaper and more attractive alternative but the repaired roof would not last as long as a new roof. Whatever the advice your roofer gives to you the following indicate that you need a new roof: 1. The decking of the existing roof is in a poor condition 2. The existing roofing has undergone extensive wear and tear and looks substandard 3. There are too many layers to the roof 4. The shingles are missing or granules have been eroded from the shingles Roof replacement is an expensive, time consuming project. Your roofer might suggest repairs and re-roofing instead. Modern roofer contractors work with a variety of materials or a combination of materials such as: concrete, slate, tar, asphalt, rubber, thermoplastic, gravel, metal and shingles. Roofs may be low slope or steep slope. Those roofs that rise more than 4 inches for every horizontal foot are termed as steep slopes, and those that rise less than 4 inches are termed as low slope. Steep slopes are usually roofed with shingles. Low slope roofs can be covered with a variety of materials in several layers. The bottom layer that is installed over the deck consists of insulation material. Molten bitumen – a tarlike material, is then applied on top of this insulation layer. Roofing felt that has been steeped in bitumen is then installed in overlapping layers over the surface. The roofer spreads the molten bitumen over the felt with a mop, sealing in the seams. This improves the water proofing of the roof. The top layer is glazed to an even finish. These steps are then repeated till the desired thickness is achieved by the roofer.
