Making timely decisions is critical to minimizing costs related to any roof repair or roof replacement.  In the case of roof repair or roof replacement, some of the most important decisions should be made before you hire your local roofing contractor. Your first decision is deciding you are going to simply repair roof leaks and damaged areas or whether you should do a partial or full roof replacement.

If you opt to do roof repair, replacing shingles due to wind damage or a fallen limb is a relatively easy and inexpensive roof repair job. Torn or damaged shingles can be removed, and new ones can be installed. The downside is that your roof repair job may not match the existing roof. However, that roof repair job could extend the life of your current roof for another 10 or 15 years. But, if you plan to sell your home in the next few years, ask your local roofing contractor to order shingles that match as closely as possible. A roof with a prominent roof repair is unattractive and could be a problem for a potential buyer.

If the roof repair job is significant but confined to one side of the roof a partial reroofing is an option. Replacing a portion of your roof could cost considerably less dollars than doing the entire roof. Repairing a section of roofing will also make it easier to blend new with old, because slight color differences will be less noticeable.  Partial roofing jobs are more expensive on a cost per square (a 10′ x 10′ area) basis and can create problems. For example, if an asphalt roof already has two or more layers, all layers will have to be removed before the new roofing material can be installed. So, in addition to increased labor and disposal costs, you may end up with the old roof slightly higher than the new one. Your local roofing contractor in the Columbia or Lexington areas can help you make the right decision for your home and your budget.

Even if only part of your roof is showing signs of wear, it is wise to consider doing the entire job while the crew is on-site with its scaffolding, ladders, and equipment. This will likely be less expensive than doing one part now and the remainder in a few years. When to replace your entire roof depends on several variables, including the shingles’ wear and age, the climate in your area, and your home’s susceptibility to future damage. Once the decision has been made to replace your damaged roof, you will have to decide whether to install your new roof over the existing one or whether to tear the old one off.  If you already have two layers of shingles, you cannot roof over the existing shingles. The International Residential Code says that you cannot put a new roof over two or more applications of any type of roof covering. One of the reasons is the weight of the shingles. A single shingle may not feel as though it weighs much, but when you cover an entire roof with shingles it is extremely heavy.  Having extra layers of shingles on your roof can cause structural damage to your home. If you have only one layer of asphalt shingles, you might want to have them removed even though you are not required to. Removing old shingles may save you money in the future because shingles will hold better if fastened directly to the roof deck. In addition, removing the old shingles will allow you to inspect the roof deck or sheathing for roof repairs that would otherwise go undetected.

The opportunity to evaluate the condition of your roof deck is valuable. Once the roof deck is exposed you can check for wood rot and the presence of inadequate sheathing fasteners. By making any necessary roofing repairs and adding fasteners to sheathing, you will avoid the losses caused when sheathing blows off the roof, allowing rain to cause extensive interior damage. Beginning your roofing job with a clean roof deck (old shingles and roofing felt removed) gives you the opportunity to add ice-and-water-shield membrane along the eaves.

A new roof can be a big expense but should last you for decades. Do it right and you will have one less thing to worry about during times of extreme weather. And, you will also end up with more money in your pocket.
