Perks of Roof Restoration
Depending on the condition of your roof, restoration over replacement may just be the right call. And if so, keep in mind these perks of roof restoration:

#1 Cost Effective
If the roof's condition is still fairly strong, the cost of repairing (as opposed to a total replacement) will be more cost effective.
That being said, if your roof is in poor condition, a repair job will likely only mask the heart of the issues and eventually a replacement may be urgent. Thus, we highly recommend getting a professional opinion before you make the decision to restore or replace the roof.
#2 Longevity
When properly restored using the right materials and methods, your roof can last for years to come.
#3 Project Time
A roof restoration takes less time to complete than a replacement. This less-time consuming project can therefore be less disruptive to your business operations and provide a lower cost of labor.
#4 Tax Benefit
When filing taxes, a roof restoration should be classified as a maintenance expenditure, as opposed to a capital expense. This classification therefore puts the tax payer in a more optimal position.
