Around 50% of all commercial buildings utilize Metal Roofing. The typical life cycle for this roofing type is 15-30 years depending on several factors, of which the most important factor is how well the owner maintains the roof.
Depending on where you are in the life cycle and how well you’ve maintained your roof over that period, there are several options to extend the life of your roof.
If you are in the early stages of your roof’s life, or you have an older roof that has held up well, putting a new application of protective coating on your metal roof will go a long way towards protecting its integrity and getting extra years out of it. The typical recoat is 1/5 of the cost of a replacement roof and should be done every 6-10 years depending on how the existing roof holds up to the elements. In addition if the coating is reflective it can add to the buildings energy efficiency.
Spray Foam Insulation
If the roof is in the latter stages of its life cycle or has not been maintained well, a less-expensive solution to full replacement is a polyurethane spray applied roof system. A spray foam solution can costs as little as 1/3 of the cost of a full replacement. Most of this due to the fact that the foam can go directly over the existing roof reducing the extensive labor costs associated with tear offs. Spray foam will also add insulation value to your roof making it more energy efficient.
If you do the math you see that if a typical metal roof replacement costs $10-12.50 per square foot, a typical recoat done every 10 years on a 30,000sf building could save you between $120,000.00 & $150,000.00 over 30 years.
If you have gone past the point of recoats and need a replacement a spray foam solution could save you as much as $250,000.00 on that same roof.
