Charlotte roofing professionals realize that for most homeowners, replacing their roof is a major expense. This high cost often leads homeowners to put off replacing the roof for as long as they can. When they are finally forced to take action, budget constraints require homeowners to look for the least expensive repair or replacement option. In some cases, the least expensive option is to install a new layer of shingles over the existing roof. While this option is a lot less expensive than completely tearing off a roof and starting over, it is not always the best choice.

There are certain advantages that come from completely tearing off an old roof prior to installing a new one. For example, tearing off the old roof makes it easy for roofers to see any problems that may exist with the old roof deck. It also makes it possible to repair the damage before a new roof is installed.

If there are any problems with condensation in the attic, these become apparent when the old roof is torn off. Condensation forms in an attic when it is not properly ventilated. This in turn can lead to mold and mildew growth, which can affect the integrity of structural components in the roof as well as the health of the home's occupants. Also, an improperly ventilated attic will lead to ice dams and can drastically shorten the life cycle of most roofing materials.

The roofing contractors from Southern Home Services of Charlotte NC would be happy to answer questions about fiber cement siding or roof repairs.

When an old roof is completely torn off, a layer of waterproofing material or an underlayment can be installed prior to applying the new roof. This adds an additional barrier of protection against ice damage or water that may seep underneath the roofing material as a result of wind-driven rain.

Starting from scratch will allow contractors to clean the deck before they apply the roofing material. This gives contractors a smooth surface to work on, improving the appearance of the finished roof.

Adding a second layer of roofing material is heavy. Not all roofs have been designed to support the weight of two layers of roofing material. Additionally, if there are problems in the roof's deck that have gone unseen, adding a second layer of roofing material will exacerbate these problems. In the worst-case scenario, this could cause a portion of the roof to cave in or collapse.

Doing a complete tear-off and starting from scratch is more expensive. However, it lessens the chance that the manufacturer's warranty will be nullified. If a homeowner does opt to add a second layer of roofing material, they should check local building codes to make sure that this is allowed in their area.
