What do I do about my commercial roof?

We get that you’re not always keeping tabs on your roof, and that you’re focused on your business – so when you finally have to deal with it, you have a lot of questions that need to be addressed, which is why we are providing a few answers to frequently asked questions:

How do I know if my roof needs replacing?
If you’re noticing leaks, your roof has already been compromised. It is recommended by the National Roofing Contractors Association (NRCA) that you get your business’s roof inspected at least twice a year – preferably every spring and fall season. Inspecting the roof for certain signs will help prevent total roof damage, signs like:

  • Missing or cracked shingles
  • Blistering or peeling paint
  • Soggy, damp shingles
  • Leakage in the attic
  • Chimney leaks

There are many other signs that your business’s roof needs replacement. We can help find them and point them out (if any).

You can get your roof inspected for FREE by Interstate Roofing.

How long should a roof last?
A roof has an average lifespan of about 20 years. It may vary depending on the roof material and roof type, as some materials have a longer lifespan and some roof types and materials don’t last as long.We can gladly help you choose the best roof material and type for your business.
Should I remove my old roof before installing a new roof?
It’s always best when replacing a roof to TEAR OFF the existing one rather than ROOF OVER the old one. Most of the time we recommend your old roof be completely removed, as we need to address the root of the problem before covering it up again. Unless the initial roof is a single, problem-free layer (which we check for), it’s best to avoid having more problems in the future with your roof by leaving the old roof on. We will inspect your roof for FREE to see whether your business’ old roof is worth keeping on or not.
How long does it take to replace a roof?
It’s hard to give an exact answer without looking at your business’s roof, as the time it will take depends on the type of roof. With most commercial properties, we are able to replace a roof anywhere from a few days to a week.The best way to know is to get a FREE estimate on your roof.
Can I replace or repair the roof myself?
We STRONGLY recommend you don’t do this, as the labor and logistics are sometimes overwhelming for the untrained and inexperienced. It’s also very unsafe to be up on your roof without proper equipment and training.We can give you estimates and options to choose from before replacing or repairing your roof.
What is the best roof for my business?
What is the best car? As this is a subjective question, we wish we had a simple answer for this – what may be best for other businesses’ roofs might not be best for your roof. It depends on your roof’s pitch, shape and style. We can give you a better answer to what is the best roof for you after inspecting it for FREE
How do I know you're not a roofing scam?
Great question. We supply plenty of certifications, credentials, references and awards to help you feel comfortable that Interstate Roofing is also a Colorado local and that we’re here to protect our community as best as we can. It’s best that you as a business owner do your research and homework to find out that Interstate Roofing has the best of intentions for your business and roofing needs.
