Residential Re-Roofing Process
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. There are important considerations to be made by a homeowner, once he/she decides to let his/her home undergo roof replacement and these considerations are calculating the cost estimates of this project, making research on a most effective and less costly roof material to use, surveying which contractor is more knowledgeable and has enough competent experience on re-roofing to back him up, and knowing what pitfalls to watch during the roofing replacement process.
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.
Any rotted wood decking found during a thorough inspection must be replaced by a new solid one, as the wood decking functions as the foundation roof structure for the roof shingles to stay on it. 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.
After the thorough inspection of the roof and before the installation of the new roof shingles, the roof specialist must prepare first the bare, roof surface by mounting three kinds of installations, which are the following: piece of metal bended at 90 degrees, called the drip edge, which is placed at all the edges of the roof to prevent water from the rain from going underneath the roof materials which are found near the edges; ice and water shield, which is a special kind of roof underlayment, that are bedded at the roof bottom and at all areas where there is possibility for rain to penetrate, like chimneys, pipes, and roof connections; roof felts placed all over the roof so that the shingles do not 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. But what spells the difference between a professional roof contractor and a commercial one is that after the installation of the new roof materials, a cleanup is done on the job site and, at the same time, a final post-roofing inspection is conducted.
