When you ask Charlotte NC roofing companies for roof repairs or a roof replacement estimate, there are several factors they consider. One important question is whether the existing roof should be torn off, or if it will be possible to re-cover, or overlay, your current shingles. The answer to this question affects time, labor, and disposal costs; ask your trusted Charlotte or Concord NC roofing expert for help.
How should I repair my roof?
Your roof is the most important component of your home, protecting everything under it. Roof repairs or roof replacement are not areas where you want to cut corners. Generally speaking, if your existing roof has just a single layer of shingles, and they lay flat, and if there are no known problems with your roof decking indicated by leaks, tearing off the old roofing material may not be necessary. When you are weighing options for either roof replacement or roof repair, seek experienced Charlotte roofing companies like Advanced Roofing and Exteriors, with roofing experts who can assess the condition of your roof and offer honest and practical advice.
Roof replacement with roof overlay cautions
A roof overlay, typically performed by reliable Charlotte roofing companies only where there is just one layer of shingles to cover, relies on absolute confidence in the soundness of the underlying roof decking.
Roof replacement over an existing traditional asphalt shingle roof means that no examination for ice or water damage, or for sheathing rot, can be made. Stripping the roof down to the sheathing is the only way to get a proper look at the condition of your decking. When Charlotte roofing companies re-cover an existing roof, other roof repairs such as installing or repairing ice and water barriers cannot be accomplished, because these barriers are properly applied directly to the decking.
Is an asphalt shingle overlay a good way to repair my roof?
Laying a second layer of asphalt shingles can be more difficult than installing new shingles. Unless heavier weight shingles cover lighter weights, a waving affect is generally noticeable on the finished roof. Flashing around sidewalls and roof penetrations can be easily compromised. Overlaid shingles often do not last as long, either, so any savings on roof repairs without a complete underlayment tear-off might actually end up costing you more in the long run.
When would a complete tear-off be needed to repair my roof?
Typically, Charlotte roofing companies advise a complete tear-off of your existing roof system if any of the following conditions are present:
- If your roof has more than one layer of roofing, local code requirements will likely prevent re-covering with shingles.
- If you notice spongy areas when walking on your roof, or if you see sags between the rafters or trusses, some of your roof decking may be damaged or deteriorated by dry rot or from plywood separation due to glue failure. Dry rot, caused by certain types of fungi, can spread if not taken care of. A complete tear-off is usually recommended.
- Ice dams can be a problem in areas where average winter temperatures drop below freezing. A full tear off should be considered if there is no ice and water protection, even if there have been no prior problems. Without protection from ice damming and water leaks, you home could suffer thousands of dollars in damage if a freak cold front hits.
- If your existing roof is in really poor shape, such as tabs on shingles being severely curled or if the rows are crooked, then a complete tear off and roof replacement may be in order.
