Duro-Last flat commercial roofs are some of the best on the market. They are both high-quality and low maintenance. Because of their durability, Duro-Last can offer a 25- and 30-year warranties.
Despite their hardiness and longevity, Duro-Last roofs are affected by severe weather and debris.
Also, over time, the color may fade due to the sun and other climate conditions. Regular care and routine maintenance prevent your Duro-Last roof from suffering damage and keeps the warranty in effect. Beware of the factors that can shorten the life of your Duro-Last roof.
Caring for a Duro-Last Roof
Duro-Last roofs are made from PVC membranes, which should never come in contact with asphalt or asphalt products. If this happens, the asphalt bleeds into the membrane, and removing it is all but impossible. Over time, asphalt weakens the membrane, resulting in loss of waterproofing and leading to destructive leaks.
Be aware that many sealants, fillers and caulks contain asphalt, so ensure any used on the roof are asphalt free. Also, be sure to speak to any contractors, HVAC installers and maintenance workers about the need to avoid any asphalt containing products when working on the roof.
Regular cleanings brighten your Duro-Last roof and make it last. Soft bristle scrub brushes work best, allowing you to clear away dust, dirt and grime. Remember to use a non-solvent cleaner. After cleaning, you can sweep away the water or let the roof dry naturally. If possible, spraying the roof after cleaning is recommended. This clears away any debris that fell on the roof during the cleaning process and removes any cleaner still clinging to the roof.
What Can Destroy Your Duro-Last Roof?
Despite the resilience and dependability of Duro-Last roofs, they are not indestructible. Certain problems can lead to roof failure, and the following are the most common:
This is perhaps the number one cause of roof failure. Always follow the Duro-Last maintenance checklist, which ensures your roof remains strong in the face of the elements. The checklist also keeps you in compliance with the Duro-Lat 25- or 30 year warranty.
As buildings settle, the movement may impact the roofing system. Also, extreme weather may cause excessive expansion and contraction of the roof. Regular inspections can determine if these issues are present and provide the opportunity to correct them before a roofing failure.
Not fixing Problems Promptly
Regular inspections may reveal problems, but they do no good if the issues are not promptly addressed. A small problem can quickly become a big one, and that hits you in the pocketbook.
Lightning, high winds, hail and severe storms can cause damage. Be sure to inspect the roof after these events.
Equipment Additions or Alterations
Hire contractors who are experienced, reliable and careful.
HVAC Service, Repair, and New Unit Installation
HVAC systems need to be worked on and installed with care.
Trade Damage: Punctures, holes, etc.
These are caused by trades workers other than roofing contractors.
Unintended Abuse, Vandalism or Accidental Damage
These things happen, providing another reason for routine inspections. Even a small hole can lead to leaks.
How to Proactively Protect Your Roofing System

One of the best parts about owning a Duro-Last roofing system is the 25- and 30-year warranties. The roofs are built to last for decades, and you want to know that the manufacturer stands behind its products. To keep your warranty in effect, be certain to maintain your roof and have Duro-Last inspect it at the required intervals: years 10, 15, 20 and 25, as well as year 23 if you have a 25-year warranty and year 28 if you have the 30 year.
Duro-Last roofing systems provide low maintenance and high functionality. To keep them in tip top shape, follow through with regular inspections and maintenance. With proper care, your Duro-Last roofing system can protect your business for decades to come.
