Being able to learn and understand effective roofing in today’s roofing technology is knowing all about the technology behind the newly-developed and advanced roofing materials and the specific kind of applications that must be used in installing these materials. While the cost estimates are a major concerned in a roof replacement project, as this is a costly undertaking, yet a homeowner must make a lot of effort in making research on the latest and available technology of roofing procedures in the market so that he/she can work this out and consult with his/her right choice or roof contractor, who is knowledgeable, as well as owning enough experience on the new roof approaches, thus preventing installation pitfalls that can affect seriously the cost and time of the project.
Property protection should be the first thing that a professional contractor should undertake, using tarpaulins and plywood to cover the areas of the house and its properties from being damaged while the old roof materials are being stripped off and replacement procedure is taking place. As soon as the other parts of the house have been shielded by tarps or plywood, the roof contractor begins the re-roofing process by first removing the old shingles completely and, at the same time, inspecting the wood decking to check if they are still in good condition.
Before any new roof shingles are to be installed, a thorough roof inspection of the wood decking must be conducted so that any wet or rotted wood will have to be replaced with a new one in order to provide a solid base roof structure for the shingles to stay well. Roof inspection must be really thorough to not just include the condition of the wood decking, but, at the same time, must be detailed in checking for missing nails, especially during the removal of the old shingles, since there is a likely chance that while new roof materials have been placed but without re-nailing the old wood decking, which will cause in the future the formation of bumps on the roof.
The roof specialist makes it a point that after a thorough roof inspection, replacement of wood decking, the entire roof surface must first be installed with protective materials, such as a 90 degree piece of metal called drip edge, which is mounted around the roof edges to prevent any rain from coming into the the roof materials that are found at the edges; ice and water shields, which are roofing underlayment, are fixed at the roof bottom and at all areas where rain can penetrate; roof felts which should be mounted all over the roof so as not to allow the shingles to stick to the wood.
The last phase in roof replacement is the installation of the new roofing materials, working from the bottom to the upper part which will followed by a series of connecting procedures, such as counter flashing, ridge vents and capping. It is equally important to require in the contract for a cleanup job after the installation of the new roof materials, as well as a post inspection to ensure that the job installation has been thoroughly done.
