In today’s roofing technology, it takes more than just having the experience to nail down on roof shingles, but because of the development of all-weather roof materials, a roof specialist must also learn the technological advantages of these roof materials, as well as getting hold of an effective, system approach to installing these materials. Basically, it is important for a homeowner to be involved in the re-roofing process, and not just be concerned on the cost of the project, but should take in information about who among the roof contractors has adequate experience, which includes knowledge of new technology on roofing, and what installation pitfalls to watch out for.
A professional roof contractor begins work by applying first protective measures to shield the rest of the homeowner’s properties from being damaged while roofing replacement is underway; therefore, the roof contractor makes use of tarpaulins and plywood to cover the rest of the residential parts while the old roof materials are being stripped off. Removal of all the old, roof shingles can take place once the nearby or adjacent parts of the house have been covered by tarps or plywood and, in doing so, a staff takes care of inspecting, at the same time, the condition of the wood decking before a new roof material will be installed.
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.
