7 Smart Ways to Maintain Complex Apartment Roofs for Long-Lasting Commercial Roofing

Why Commercial Roofing for Apartment Buildings Is More Complex

Roofing for apartment buildings isn’t as simple as it is for single homes. The maintenance of these buildings is more difficult because they are bigger and often share access, HVAC units, and other equipment on the roof.

Since most fall under commercial roofing, strata roofing, or industrial roofing, poor upkeep can affect many tenants and lead to liability issues.

Heavy foot traffic, mixed roofing materials, and Vancouver’s changing weather all speed up wear and tear. And when you add solar panels or mechanical systems, even flat roofing becomes harder to manage.

That’s why proper maintenance of commercial roofing for buildings means using the right materials and keeping up with regular inspections.

1. Schedule Regular Inspections for Commercial Roofing Systems

It’s smart to get your roof checked by a professional twice a year—once in the spring and again in the fall. Why? Because that’s when you can catch small problems before they turn into big, expensive ones.

Things like:

• Water that just sits there on flat roofing
• Cracks or bubbles showing up in the surface
• Rust on metal parts
  
  

The Roofing Contractors Association of British Columbia (RCABC) says regular inspections are one of the best ways to avoid serious damage later on.

These check-ups don’t just protect the roof—they also help it last longer, keep people safe, and make sure you’re covered when it comes to insurance.

In between those scheduled inspections, it’s a good idea for someone on site to do a quick look—especially after storms or rough weather.

This goes for commercial roofing, industrial roofing, roofing for buildings, and even strata roofing.

2. Keep Drains Clear to Protect Flat and Strata Roofing

If you don't clear out your drains, scuppers, or gutters, water can build up on your roof. That's a big issue, especially for flat roofs that are common on apartment buildings. If the water just sits there too long, it can cause serious damage to the whole commercial roofing system.

That’s why it’s important to keep leaves, twigs, and other junk out of the way. This matters even more in rainy places like Vancouver. According to Environment Canada, it rains there about 161 days a year. Therefore, ensuring your roof drains effectively is crucial.

If you manage a property, it’s smart to schedule regular cleanups for gutters and drains. Fall is an especially bad time for clogs because of all the falling leaves. Adding mesh covers or leaf guards can help stop stuff from piling up and keep your commercial roofing system in good shape.

No matter if it’s strata roofing, industrial roofing, or any other kind of roofing for buildings, having good drainage keeps everything safer and drier.

3. Repair Roofing Issues Quickly to Prevent Expensive Damage

If you have an industrial or commercial roof that covers a lot of room, a small leak might not seem like a big deal at first, but it can quickly become one. If you wait too long, the building is more likely to get damaged, renters will complain, and there will be even more damage.

Leaks can soak insulation, cause mold, or mess with electrical systems. A quick fix might get you by for now, but having a pro handle the repair the right way helps your roof last longer and saves you money down the line.

Whether it is flat roofing, strata roofing, or any kind of commercial roofing for buildings, make it a habit to write down every repair or inspection. It helps you keep track of recurring issues and makes life easier if you ever need to file a warranty or insurance claim.

4. Regular Maintenance Keeps Commercial Roofing in Good Shape

You might have to pay a lot more in the long run if you wait until your roof has a big problem. That's why it's important to do regular maintenance. Your commercial roofing will last a lot longer if you do simple things like seal the joints, put on a new coat of coating, and check the flashing.

For strata roofing, regular maintenance is often required by building bylaws or even provincial housing rules. In fact, many local governments recommend—or require—long-term planning that includes roof inspections and upgrades. Staying on top of this not only helps avoid sudden repair bills, but it also keeps things running smoothly for residents.

Having a roof care plan in place protects your property’s value, helps with energy savings, and keeps your commercial roofing for buildings working the way it should.

5. Use the Right Materials for Complex Roofing for Buildings

When fixing or improving a building's roof, it's very important to use the right materials. If you use the wrong kind of glue to fix a hole in an EPDM rubber roof, it might peel off too soon or wear out faster than you planned. That’s why it’s so important to follow the guidelines provided by certified sources like the National Research Council Canada (NRC Canada), especially for commercial roofing or industrial roofing projects.

Mixing materials without the right bonding agents or underlayment can weaken the whole system. If you're unsure, it’s best for property managers to check in with the manufacturer or even an engineer to confirm what works together.

Choosing better, weather-resistant materials upfront—whether for flat roofing, strata roofing, or other complex building types—can also save time and money down the road by cutting down on repeat repairs.

6. Educate Building Staff and Residents About Roof Safety

People going up on the roof without permission can cause damage without meaning to. That's why it's important to tell tenants and workers not to go on the roof and to report any damage they see. You can also put up warning signs or set up cameras if needed.

This matters even more for strata roofing, where many people live in the same building and might not be clear about who’s allowed on the roof.

It’s also a good idea to hold short seasonal meetings or add roof safety tips in your monthly newsletter. When everyone helps take care of the building, it’s easier to spot problems early and keep the roof in better shape for longer.

7. Work with Certified Pros in Commercial and Industrial Roofing

When you're working on a big project like an apartment building or a commercial building, you need to hire roofers who know what they're doing. Not just anyone with a ladder and shingles should do the job. When looking for contractors, make sure they have a license, a certification, and a lot of experience with business and industrial roofing.

A quick and easy way to check? Check to see if they belong to known groups like RCABC. And always ask for examples of similar work they've done, especially if it has to do with commercial roofing for buildings like yours. 

Make sure they’re familiar with the kind of roof you need—whether it’s flat roofing, strata roofing, or something more complex. These pros should know the latest safety rules, offer proper warranties, and help you avoid costly issues later.

Before you sign anything, ask how many large properties they’ve worked on, what roofing systems they recommend, and if they offer maintenance plans. A company that sticks around after the job’s done? That’s the kind of support that really pays off.

Local Tips: How to Take Care of Commercial Roofing in Vancouver

If you’ve got a commercial, industrial, or flat roofing system in Vancouver, you already know the weather can be a pain. With all the rain and damp conditions, moisture problems are pretty common—especially in the fall and winter.

A simple way to stay ahead of trouble? Get your roof checked out before the rainy season starts, and again after it ends. Catching small issues early can save you from bigger, more expensive problems later.

Use sealants and materials that are made to handle high humidity. Vancouver’s climate isn’t forgiving, so it’s worth using products that are built for it.

In the summer, heat can also be a concern. Choosing reflective or energy-smart roofing materials can help keep buildings cooler and even extend the life of your roof.

Whether it’s for strata roofing, commercial roofing for buildings, or something more heavy-duty like industrial roofing, a little upkeep goes a long way.
