Roof replacement is something dreaded by most owners of homes and businesses, not only because of the huge investment it requires, but also because of the disruption and the mess caused by the process. However, no roof lives forever, so if you notice one or more of the following signs, you should put up with the idea that you will soon need a new roof:

• Roof age – if the material that your roof has been made from is approaching the end of its lifespan, you should start saving up for a new roof, even if the roof surface still looks good and you don’t get any serious roofing problems;
• Shingle damage – curled or cupped shingle edges, cracked shingles or tiles, shingles that no longer have surface granules can be repaired as long as the problems affect only few components. If the problems spread or become generalized, the roof needs complete replacement;
• Roof sagging – in many cases, but not always, sagging roofs can be fixed by professional Dallas commercial roofers who will use various lifting devices to straighten the roof and to replace the damaged beam or other structural components. If you notice that your roof is affected by sagging, call a roofing expert to perform a detailed inspection of the roof and to suggest the best course of action.
