10 Tips to Make Residential and Commercial Roofs Last Longer

By Level Up Canadian Roofing & Exteriors – Serving Richmond & the Lower Mainland

Your roof is one of the biggest investments in your property — whether it’s your home, strata complex, or commercial building. With proper care, you can extend its lifespan by years and avoid costly repairs or premature replacement.
Here are 10 proven tips from local roofing experts to help you get the most out of your roof.

1. Schedule Annual Roof Inspections

A professional roof inspection at least once a year (and after major storms) helps detect early signs of wear. Minor issues like lifted shingles, cracked flashing, or clogged drains can quickly become leaks if left unchecked.

2. Keep Gutters Clean

Blocked gutters and downspouts cause water to pool and back up under shingles. Clean them regularly, especially in fall and spring, or install seamless aluminum gutters with leaf guards for a low-maintenance solution.

3. Repair Leaks Immediately

Even small leaks can cause major structural and mold damage over time. Address roof leaks as soon as they appear to prevent water infiltration and rot.

4. Maintain Proper Attic Ventilation

Good ventilation prevents condensation and heat buildup that can damage roofing materials. Make sure your attic has enough intake and exhaust vents to regulate temperature and moisture year-round.

5. Trim Overhanging Branches

Tree branches can scrape shingles or break during windstorms, causing punctures and debris buildup. Keep trees trimmed at least 3 feet away from the roofline.

6. Replace Damaged Shingles or Flashing

Damaged or missing shingles leave your roof vulnerable to water intrusion. Replace them promptly and check all flashings around vents, chimneys, and skylights for cracks or rust.

7. Ensure Proper Drainage on Flat Roofs

For commercial or low-slope roofs, make sure drains and scuppers are clear of debris. Standing water shortens membrane life and leads to leaks.

8. Avoid Pressure Washing

High-pressure washing can strip away protective granules from shingles and cause leaks. Instead, use gentle cleaning methods or hire a professional to remove moss and algae safely.

9. Maintain Sealants and Roof Penetrations

Sealants around vents, pipes, and skylights degrade over time. Re-seal them every few years to keep moisture out and extend the roof’s waterproofing.

10. Hire Certified Local Roofers

Work with licensed, insured roofing professionals in Richmond who understand local weather conditions. Certified installers ensure proper materials, warranties, and workmanship that lasts.

Final Thoughts

Whether it’s a residential roof or a commercial flat roof, consistent maintenance and professional inspections can easily add 5–10 years to its lifespan.
