Leaking is a common problem that occurs with a flat roof. Water sits on top of the roof and can’t drain as well without an inclined roof, so it may find its way into cracks and crevices. Sometimes, a damaged commercial flat roof can be repaired, but other times, the damage is too extensive and the roof needs to be replaced. To make the most of your budget, know when to make Houston commercial roof repairs and when to replace.
When to Repair
A leaky roof is not necessarily a sign that a flat roof needs replaced. A full roof replacement can be costly and is a last resort. If a flat roof is still within its service life, it should be repaired first. A commercial flat roof repair company can make repairs such as applying roofing level compounds that will level out a low area that is retaining water to allow for proper drainage. It can also spread the water out over a larger surface so it will evaporate faster and not just sit in one spot on the flat roof. Installing tapered insulation under the first membrane can also help seal out water leaks. Regular maintenance on commercial flat roofs is key to having a roofing system that lasts.
When to Replace
If a roof is nearing the end of its service life and is needing more and more frequent commercial flat roof repairs, replacing a flat roof may be the more viable option. A service life for flat roofing systems can range anywhere from 5 years to 7-10 years depending on the material. Improper installation can cause all sorts of problems for a flat roof. If your roof was not installed correctly, a roofing replacement could be the best financial option. Different roofing materials for flat roofs may also make a difference. For instance, leaks in tar or gravel roofs can be hard to identify and thus a roof replacement may be necessary.
