Why should you consider repairing or replacing your roof? The need to repair or replace your roofing system might be attributed to different things. This could be inclement weather conditions, poor installation, age, type of materials. All these factors might contribute to the decline. Some signs in your roof might be indicative of a problem.
WHAT INFLUENCES THE DECISION TO REPAIR OR REPLACE?
ROOFING MATERIALS
Most roofing materials last between 15 and 20 years. Unless there is significant 
damage, simple repairs might solve most problems that occur during this duration. However, some materials like copper can last significantly longer before their time for replacement comes. In this regard, when looking for the material of choice, you also need to consider how long they can be used before being replaced. Once their expiration date is close, replacing the roof is better that attending to repairs.
WEATHER
Major storms might cause significant damage to your roof. The decision to repair or replaced should be reached at after the roof is inspected. For instance, a huge tree or any heavy object fell on your roof; the best thing to do is to work with a roofing contractor. If the inspection report only finds minor cracks, missing shingles, and other minor damages, simple repairs can do. Besides inspection, here are some signs that could suggest the possibility of having problems in your roofing system.
INTERNAL SIGNS
In most instances, these signs are associated with leaking roofs. This could be things like water stains, sagging roofs, or even presence of mold. Unfortunately, noticing these signs might be difficult for an untrained eye during the initial stages. Therefore, you need to have a professional roofing contractor to ascertain whether these problems are from the roof or plumbing systems.
EXTERNAL SIGNS
In most instances, these signs are not noticeable. If you do not have the time to keep inspecting your roof, you might notice things like missing tiles, or even growth of algae under your roofs. With times, such problems end up allowing damaging rainwater into your home.
The decision to replace or repair can save or cost a significant amount of money. If a repair is needed, you will save much more than you would have for a replacement. However, if the material used are almost expiring, it may cost less to replace the unit than to keep repairing.
