Maplewood, NJ Roof replacement or remodeling occurs when the damage is too great to repair a section of the roof, the roofing materials are old or outdated, or the homeowner decides to renovate the building. Methods of re-roofing include the “tear-off” and “lay over” methods, and the choice of method depends on the roofing material used originally, the condition of the old roof, the accessibility of the existing roof’s interior and the extent of the damage.
Tear-Off Method
Depending on the roofing material used, it may not be feasible to lay new shingles over the old. While this is usually the less expensive route, it is not necessarily the best decision. In the tear-off process, the old roof is removed in its entirety. This enables the Maplewood, NJ roofing contractor to examine the inner section of the roof and evaluate the condition of the trusses or rafters. He can also make any necessary flashing repairs and identify condensation or other moisture problems in the attic. For homeowners who select a long-lasting roofing material such as metal, this process provides the opportunity to install new waterproofing underlayers to protect against future leaks, and it allows the Maplewood, NJ contractor to correct any ventilation problems that may result from an old, inferior roof.
Lay-Over Method
This process is best used when a roof is being replaced or remodeled for mainly aesthetic purposes. Provided that the original roof is intact or needs only minor repairs, the wooden supports pass inspection for rot and moisture, and they are deemed strong enough to support the additional weight, a new roofing material may be laid over the old.
Take-aways
While the lay-over method of replacing a Maplewood, NJ roof is acceptable, it is not always the wisest choice. It may also be subject to building codes, so the homeowner should carefully evaluate the practical aspects of using this method. For a long-lasting roof, the tear-off process is frequently a better prospect.
