What types of commercial and industrial roofs do you install?

We install flat, low slope, metal, TPO, EPDM, PVC, and built up roofing systems.

We work with top manufacturers like GAF, Carlisle, Johns Manville, Versico, Sarnafil, and Garland to deliver roofs built for performance and longevity.

It depends on the material and how well it’s maintained.

Metal and TPO roofs can last 20 to 35 years, while built up roofs typically last 15 to 25 years. Regular maintenance helps you get the most out of any roof.

All three are single ply membranes, but each has its strengths.

TPO is a popular, energy efficient choice with a reflective white surface. EPDM is a durable rubber membrane known for handling temperature swings. PVC holds up especially well against chemicals and grease, which makes it great for restaurants and industrial facilities.

Can you replace our roof without disrupting business operations?

Yes. We plan every project around your schedule to keep downtime to a minimum and your operations running smoothly.

It depends on the size of the roof, the system being installed, and the weather.

Smaller projects may take a few days, while large industrial roofs can take several weeks. We’ll give you a clear timeline before any work begins.

How do I know if my commercial roof needs repair or replacement?

Common signs include leaks, ponding water, damaged flashing, and worn or blistered roofing materials.

Our team will do a thorough inspection and give you an honest recommendation on the best option for your building and budget.

For more information on signs of replacement, check out our blog: 7 Warning Signs Your Commercial Roof Needs Replacement.

Move equipment and inventory away from the leak, catch the water if you can, and call us right away.

The sooner a leak is addressed, the less damage it can do to your building, insulation, and operations.

Yes, we do offer 24/7 emergency roof leak repair. Roof problems don’t wait, and neither do we.

Our emergency team is available around the clock at (810) 742-7373 to protect your property when you need us most.

We do. High winds, hail, and heavy snow can all take a toll on commercial roofs.

We’ll assess the damage, provide detailed photos, and make the repairs needed to protect your building from further harm.

In many cases, yes.

If your roof is in decent shape overall, a coating can seal problem areas, improve durability, and add years of life for far less than a full replacement.

How long has National Roofing & Sheet Metal been in business?

What is the Umbrella Program?

The Umbrella Program is our commercial roof maintenance plan.

It keeps your roof professionally maintained with scheduled inspections and upkeep, so small issues get caught early before they turn into costly repairs.

We recommend inspections at least twice a year, ideally in the spring and fall.

It’s also smart to have your roof checked after any major storm.

We check the membrane, seams, flashing, drains, and rooftop penetrations for damage, wear, and ponding water.

You’ll get detailed reporting with photos so you know exactly what’s going on with your roof.

Routine maintenance extends the life of your roof, prevents surprise leaks, and helps you avoid expensive emergency repairs.

It can also help keep your manufacturer warranty in good standing.

Clear drains and gutters, check flashing and seams, and schedule a fall inspection to catch any weak spots before the snow hits.

Heavy snow loads and freeze thaw cycles can turn small problems into big ones fast.
