Costs of an Old Commercial Roof

With the rising cost of living, it’s straightforward to postpone your plans to replace your old commercial roof. The cost of replacing a commercial roof can be high, especially when the world is going through tough economic times. A sizeable commercial roof can also take a long time to replace.

However, the cost of replacing your roof and the time it takes to return are not enough reasons to retain an old commercial roof. The cost of not replacing the roof is far greater than the actual cost of replacing it. Continue reading to know the costs of an old commercial roof.

Pest Invasion

As time passes, your old commercial roof will develop weak spots or openings in areas where roofing materials have been repetitively stressed or knocked by external elements like falling branches. These openings become good access points for pests, including rats, raccoons, bats, opossums, and other opportunists.

These pests will take advantage of your old roof to burrow into the attic or crawlspace. While these animals might appear innocent, they will wreak havoc in your commercial building, forcing your tenants to flee. They will also destroy your valuables and leaving you and your tenants counting huge losses. They also carry parasites and microbes that can cause serious diseases.

Attic Air Flow Problems

As your commercial roof grows old, its ventilation becomes fragile, leaving the airflow compromised. Mold and mildew will also start to grow because of the condensation that occurs around the roof. With mildew and mold growing on your roof, the speed of deterioration increases, leaving your commercial roof unstable. If the roof is not repaired or replaced immediately, these problems will spread from the attic to other ceiling areas. Overall, an old roof is bound to cause more severe problems in the future.

High Energy Costs

Your commercial roof requires reliable and effective insulation to keep your building warm in winter and cool in summer. So, if your insulation is compromised, it will let the heat and cool air out of the building in the cold and hot seasons, causing your heating and cooling systems to overwork. This results in increased energy costs.


Your old commercial roof will likely trap moisture from the rain, hail, storms, and sleet. This can cause ice dams and large pools of water to form on your roof. Eventually, your roof will start to leak, causing flooding and other water damages in your building. So, make sure your old commercial roof is repaired or replaced as soon as possible.
