A new roofing system for your commercial building is a big investment, as well as the most important component when it comes to protecting your facility from the elements. So, it’s important to make sure that the warranties covering your new installation (issued by the manufacturer and/or the installing contractor) remain in effect for the life of your roof. Warranties differ and it’s important to understand what might impact your manufacturer or contractor warranty. Here are a few things that could cause your warranty to be voided.
Inadequate insulation and/or ventilation can foster condensation underneath the roofing system, potentially damaging multiple components, including fasteners, insulating materials, decking, wood pieces and the like. A roofing system warranty may not cover this type of damage.
Some roofing system warranties may be voided if the use of the roof changes. For example, installing skylights, solar panels, vegetative roofing systems and satellite dishes could cause roof penetrations or additional burdens and make your warranty useless. Before installing anything on your roof it is important to talk to your roofing contractor and whoever is installing the new components about how the roofing system warranty will be affected. If you are planning a new roofing system and may – at the same time or down the road – add one of these items to your rooftop, consider an “overburden” warranty for the roofing system, which is designed to accommodate the new equipment.
New single-ply roofing systems are often white or a very light color, and highly reflective. Unfortunately, these roofs can collect dirt and lose their energy-saving effectiveness. To restore reflectivity, building owners can clean the roof, which is a good thing. If they use a pressure washer to clean it, that could be a bad thing. Pressure washing could be extremely damaging to the roof, because the water force can actually remove roofing material and penetrate the membrane. Damage and leaks caused by pressure washing will probably not be covered by any roof warranty. All manufacturers have their own recommended cleaning methods, but typically, they involve soft bristle brushes, non-solvent / non-abrasive detergents, squeegees, and low-pressure water spraying.
Being aware of its terms and conditions when making roof decisions will help ensure that your warranty provides strong coverage for the life of your roof.
