Can I install a new commercial roof on top of my old one?

While it is technically possible to install a new roof over an existing roof in some areas, we recommend avoiding this whenever possible, as it can potentially compromise the new roof's integrity.

For example, if moisture has seeped into your old roofing system, those areas will become damaged and blistered, which can compromise the new roofing membrane.

How often should I inspect a commercial roof?

Scheduling a regular annual inspection of your commercial roof is the best way to prolong its lifespan and to minimize costly repairs.

If you ever notice interior leaks, signs of damage (even minor signs), or pooling water, you should contact a professional commercial roof inspector immediately to ascertain the extent of the problem.

Other times you should have your commercial roof inspected:

1. Before "bad weather season" hits
2. After a big storm
3. After "bad weather season" is over
