In recent years, asphalt shingle manufacturers have been reducing the amount of asphalt they put in each shingle. The result is that roofs advertised to last 30 years sometimes last as little as 10-15 years before needing replacement. Roof Renew extends the life of your roof for 5 years with each treatment, and you can apply the treatment up to three times, for a total of 15 years of extended life for your roof.
Here's the math:
Cost of roof replacement: 2,800 sqft. x $4.00/sqft. = $11,200
Cost of Roof Renew: 2,800 sqft. x $0.86/sqft. = $2,408
As you can see, Roof Renew is a truly revolutionary advancement in roof maintenance, that extends the life of your roof for much less than the cost of replacement.
