  • We had a very bad leak in our roof, which required a section to be replaced. The guys at Ajax Roofing did it very quickly, and didn't leave me with a mess to clean up after. I'd highly recommend them!
    Jeff Quipp
  • The roof was done quickly and the yard cleaned up was perfect. The roof looks great even the neighbors say so. Thank you Travis and all your crew. The amount that the job was comparable to other companies around

  • Just a very quick THANK YOU to Travis and his gang. They saved us twice. First time in the winter, when our gutters froze and the roof needed some FAST attention. Second, after our roof was completely redone and also destroyed by a "fly by night" company. Travis recommended the proper action and worked with us at more than professional level. Thank you! You guys rule! Would highly recommend this company to anyone, on the spot!

What is Cellulose Insulation?

Ajax Roofing also installs cellulose attic insulation - this product is superior to fiber glass insulation.

Cellulose insulation is a type of loose-fill insulation made from recycled wood fiber, primarily waste newspaper and cardboard. The wood fiber, which is composed of cellulose, is shredded and pulverized into small, fibrous particles that pack tightly into closed building cavities, inhibiting airflow. This provides a thermal resistance of R-3.6 to R-3.8 per inch.

Manufacturers add chemicals to the cellulose to make it insect and fire resistant.

The NRDC has concluded the following:

  • Cellulose insulation manufactured from recycled paper is the least polluting and most energy efficient insulation.
  • Cellulose has the highest post-consumer recycled content. The fiberglass industry averages 35% recycled glass, while the cellulose industry averages a minimum of 75% recycled content.
  • It takes more than 10 times as much energy to produce fiberglass insulation as cellulose insulation.
  • Due to air circulation and natural convection, the R-value of blown-in fiberglass insulation decreases by as much as 50% as the temperature drops from 45 degrees F to 18 degrees F.
  • Cellulose has better resistance to air flow and prevents the upward movement of air caused by temperature differences (the R-value of cellulose actually improves during cold weather).
  • Substantial and well-documented public health threats are associated with fiberglass.
  • No adverse health effects from cellulose insulation have been identified.

Insurance & Sponsors

In all of our years in the roofing trade we have never had an insurance claim. Part of the reason is that we do not use subcontractors at all. Using subcontractors is one of the leading causes of claims in the roofing industry. It is actually one of the first questions a roofer is asked when filling out the insurance questioner each year at renewal time, do you use subcontractors? YES or NO?

The insurance industry knows the problems with sub contactors and so do we. In our opinion sub contractors do not take the pride in roof installation that we have always required. All of our employees are highly skilled trades people paid per hour. One of the company owners are always on the roof or monitoring the crews constantly to keep quality control extremely high and any dangers leading to insurance claims extremely low. We believe that having one of the principal company owners in charge of each jobsite insures a quality job and a safe working environment.
