Because the primary objective in roofing replacements or in re-roofing process is to protect one’s home, any plans of roof repairs or complete roof replacements must be seriously considered and well-understood by the homeowner, as new roofing technologies applicable to advanced roof materials are now available in the market and are found to be more effective, and, thus, the homeowner should take time to be explained by a roof specialist on the best and effective approaches that would be adapted once these newer roof materials are put in place. 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.
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. When the residential property has been well-protected with plywood or tarps, the removal of the old roof shingles begins until all of them have been completely taken out, while another team works out in inspecting the wood decking if they are still in good condition.
Thorough inspection of the wood decking must be conducted, before installing the new roof shingles, so that any found rotted wood can be replaced with a new solid one as wood decking serves as the foundation structure for the roof shingles to lodge on. Roof inspectors must be careful to thoroughly check the roof parts, which includes for missing nails, so as not to result into bumps formation on the roofs which is due to not nailing back the old wood decking during the installation of the new shingles.
Once the wood decking has been inspected and prepared, the roof specialist prepares, too, the roof surface by installing the following: drip edge, a piece of metal bended at 90 degrees, at the edges of the roof to prevent rain from getting underneath the roof materials located near the edges; ice and water shield, special roofing underlayment, which is installed at the roof bottom and at all areas where water can penetrate, such as chimneys, pipe flanges, roof connections; roofing felt which is installed all over the roof to prevent shingles from sticking 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.
