How to Extend the Life of Your Commercial Roof
One of the biggest investments you'll make is in your commercial property, and a critical component of that is the roof. A well-maintained commercial roof can last for decades, while a neglected one may need to be replaced much sooner. At Utz Roofing, we specialize in commercial roofing and want to share some tips on how you can extend the life of your roof and avoid costly repairs or premature replacement.
Choose the Right Roofing Material
The first step in extending the life of your commercial roof is selecting the right roofing material for your building and climate. There are several options to choose from:
Asphalt Shingles: Asphalt shingles are a popular choice for commercial roofs, especially on smaller buildings or those with steep slopes. They are relatively inexpensive and easy to install. Architectural shingles are a premium type of asphalt shingle that offer a more distinctive look and better durability than standard 3-tab shingles.
Metal Roofing: Metal roofs are durable, energy-efficient, and can last 40-70 years with proper maintenance. They are a good choice for buildings in areas prone to wildfires or severe weather.
Single-Ply Membrane: Single-ply membranes like TPO and EPDM are popular for low-slope or flat commercial roofs. They are lightweight, relatively inexpensive, and easy to install.
Built-Up Roofing (BUR): BUR systems are made of alternating layers of bitumen and reinforcing fabric and are topped with a layer of gravel or mineral granules. They are durable and offer good waterproofing but can be heavy and labor-intensive to install.
An experienced commercial roofing contractor like Utz Roofing can assess your building and recommend the best roofing material based on your budget, climate, and aesthetic preferences.
Ensure Proper Installation
Even the highest quality roofing materials won't perform well if they are installed incorrectly. Improper installation can lead to leaks, premature wear, and even structural damage. When selecting a commercial roofing contractor, look for one with experience, proper licensing and insurance, and a track record of quality workmanship.
Some key aspects of proper commercial roof installation include:
Adequate ventilation: Proper roof ventilation helps regulate temperature and moisture levels in the attic space, which can prevent issues like ice dams, mold growth, and premature aging of roofing materials. Ridge vents, soffit vents, and gable vents are common types of roof ventilation used on commercial buildings.
Correct flashing techniques: Flashing is the material used to seal areas where the roof meets walls, chimneys, skylights, or other protrusions. Proper flashing techniques are critical for preventing leaks and water damage.
Appropriate fasteners and adhesives: The type and placement of fasteners and the quality of adhesives can impact the wind resistance and overall durability of the roof system.
Adequate underlayment: Installing a high-quality underlayment beneath the roofing material provides an extra layer of protection against water intrusion.
Schedule Regular Inspections and Maintenance
One of the most important things you can do to extend the life of your commercial roof is to have it inspected and maintained on a regular basis. The National Roofing Contractors Association (NRCA) recommends inspecting commercial roofs at least twice a year - once in the spring and once in the fall.
During a roof inspection, a qualified professional will look for signs of wear, damage, or potential problems, such as:
Cracked, curled, or missing shingles
Worn or cracked seals around flashing
Rust or corrosion on metal components
Ponding water or clogged drains on flat roofs
Damaged or missing chimney caps or ventilation equipment
Debris accumulation
Signs of animal or insect infestation
Catching and addressing these issues early can prevent more extensive and expensive damage down the road. Regular maintenance tasks may include:
Cleaning gutters and downspouts
Removing debris from the roof surface
Resealing around flashing, vents, and other penetrations
Repairing or replacing damaged shingles, tiles, or membranes
Restoring protective coatings or reflective surfaces
Establishing a maintenance plan and sticking to it can significantly extend the serviceable life of your commercial roof. Many commercial roofing contractors, including Utz Roofing, offer maintenance plans that include regular inspections and discounted repair services.
Address Drainage Issues
Poor drainage is a common cause of premature commercial roof failure, especially on low-slope or flat roofs. When water is allowed to pond on the roof surface, it can lead to a host of problems, including:
Accelerated wear and deterioration of roofing materials
Leaks and water damage to the interior of the building
Plant, algae, or fungal growth
Increased risk of ice dams in cold climates
Deflection or structural damage due to the added weight of ponding water
To promote positive drainage, commercial roofs should be designed and installed with a minimum slope of 1/4 inch per foot. Flat roofs may require additional drainage elements like interior drains, scuppers, or gutters and downspouts.
Existing commercial roofs with drainage issues can often be retrofitted with tapered insulation systems, crickets, or saddles to promote positive drainage. A skilled commercial roofing contractor can assess your roof's drainage and recommend solutions to prevent ponding water and associated damage.
Manage Roof Traffic
Commercial roofs often have equipment or features that require regular access, such as HVAC units, skylights, or communication equipment. However, excessive foot traffic can damage roofing materials and lead to premature failure.
To minimize damage from roof traffic, consider the following:
Install designated walkways using materials like rubber mats, concrete pavers, or sacrificial membranes.
Limit access to trained personnel who understand how to walk on the roof without causing damage.
Avoid accessing the roof in very hot or cold weather when materials may be more susceptible to damage.
Keep the roof surface clean and free of debris that could conceal hazards or damage.
If your commercial roof has experienced damage from foot traffic, have it repaired promptly by a professional to prevent further deterioration.
Invest in Roof Coatings or Overlays
Applying a protective coating or overlay to your commercial roof can extend its life by several years. Roof coatings are liquid-applied materials that form a seamless, waterproof membrane over the existing roof surface. They can be made of acrylic, silicone, or polyurethane and offer benefits like:
Reflecting UV rays to reduce cooling costs
Resisting ponding water and moisture intrusion
Protecting against chemical or environmental damage
Extending the serviceable life of the roof by 10+ years
Roof overlays involve installing a new roofing membrane directly over the existing roof surface. This can be a cost-effective alternative to a full tear-off and replacement, especially if the underlying roof deck is still in good condition.
An experienced commercial roofing contractor like Utz Roofing can assess your roof's condition and recommend whether a coating or overlay is a viable option for extending its life.
Monitor Interior Spaces for Signs of Problems
Even with regular inspections and maintenance, commercial roofs can develop leaks or other issues between service visits. Building owners and managers should monitor interior spaces for signs of roof problems, such as:
Water stains on ceilings or walls
Mold or mildew growth
Musty odors
Sagging or soft spots in the ceiling
Increased energy bills (may indicate wet insulation)
If you notice any of these signs, have your roof inspected by a professional as soon as possible. Catching and repairing leaks early can prevent more extensive damage to your building's structure and interior.
Know When to Replace Your Commercial Roof
With proper maintenance and care, a commercial roof can last for decades. However, all roofs will eventually reach the end of their serviceable life and require replacement. Signs that it may be time to replace your commercial roof include:
Age: Most commercial roofs have a lifespan of 20-30 years, depending on the material and quality of installation. If your roof is approaching or exceeding this age, replacement may be more cost-effective than continuing to repair it.
Extensive or recurring leaks: If your roof is experiencing frequent or widespread leaks, it may be more economical to replace it rather than continue to patch it.
Widespread damage: If a significant portion of your roof surface is damaged or deteriorated, replacement may be necessary to protect your building from water intrusion and structural issues.
Energy inefficiency: Older roofs may lack insulation or reflective properties that can help reduce energy costs. Replacing an inefficient roof with a modern, energy-efficient system can provide long-term savings on utilities.
Planned renovations: If you are planning a major renovation or expansion of your building, it may make sense to replace the roof at the same time to ensure compatibility and avoid disrupting the new construction.
A reputable commercial roofing contractor like Utz Roofing can provide a thorough assessment of your roof's condition and help you weigh the costs and benefits of repair versus replacement.
Your commercial roof is a critical asset that protects your building, its contents, and the people inside. By following these tips for extending the life of your roof, you can avoid costly repairs, minimize business disruptions, and get the most value from your investment.
Remember to choose a high-quality roofing material that is appropriate for your building and climate, and have it installed by a reputable contractor with experience in commercial roofing. Establish a regular maintenance and inspection schedule to catch and address minor issues before they become major problems. Consider investing in protective coatings, overlays, or drainage improvements to further extend the life of your roof.
When it does come time to replace your commercial roof, choose a contractor like Utz Roofing who can provide expert guidance and quality workmanship. With proper care and maintenance, your new roof can provide decades of reliable protection for your commercial property.
