Nothing lasts forever – not even the most solid and professionally maintained roof. At some point in the life of a large commercial or industrial building, the roof will need to be replaced. Most roofs come with a life expectancy of about 20 years and, while that life expectancy can be extended with regular maintenance, eventually the roof will need to be replaced. Here are some tips that it’s time to replace the roof.
It’s not uncommon for roofs to experience leaks occasionally, but if they are occurring frequently, and after repairs have been made, it may be time to replace the roof altogether.
Discoloration On The Ceiling
If you begin to notice discoloration on your ceiling, it’s a sign that moisture is penetrating through the roof and into layers underneath. If this happens frequently, and in several areas, it’s a sign that the roof has major problems.
Major Overhaul or Expansion of Related Building Systems
Are you planning on a major expansion or renovation of your building? If so, this may be the perfect time to replace your aging roof. Often, a major renovation involving the HVAC system can place such a traffic load on an old roof that it becomes the next thing you are fixing constantly. Planning to do both at once allows you to coordinate the contractors and your expenditures. The same goes for a building expansion. Quite often, the traffic on the existing area can be very hard on a system that is near the end of its life.
Flat roofs are often made up of large, distinct areas. Having a lot of trouble in one particular area, near the drains, for example, can be a sign of impending issues in areas that are not under as much duress. Over time, issues can spread as age and weathering impact the entire roof. Make sure to listen to the areas that are the leading indicators of wear and tear. These are typically the areas handling the water or at the edge of the building. Flashings and seams are also critical areas that can give early warning signs that a roof is nearing the end of its useful life.
Warranty Is Up
Most roofs come with a warranty from the manufacturer. If major repairs are needed and the warranty has expired, consider that an omen that it’s time to replace the roof.
Ultimately a building owner has to use his or her best judgement on deciding whether a roof needs to be fixed or replaced. But if there’s a long list of concerns and repairs are needed on a frequent basis, it’s time to consider whether those repairs are really worth the investment. At some point it becomes time to let go and make the larger and more responsible purchase.
