• Ventilation is Key to How Long Your Roof Will Last
  More than ever, homeowners are frustrated by poor performing roofing products and upset when a new roof costing between $5,000 and $10,000 lasts only 12 to 15 years. In some cases, it is a troublesome brand of materials. More often, however, it is inadequate attic ventilation.
  

  Building standards, driven by energy shortages, have sewn up the homes that we live in tighter than a drum. Surprisingly, standards of ventilation adopted in the 1930s are still in use today! Most homes are woefully under ventilated.

  
  Ventilation should be a major concern to anyone who is contemplating having their home re-roofed. It is common for the average household to produce from four to five pounds of water vapor per day. To illustrate how much water that is, go to your kitchen sink, fill an empty one-gallon container with water, and pour that on the floor. In poorly ventilated homes, this moisture has nowhere to go. So it forms condensation on the underside of the plywood sheeting of the roof, causing the plywood to expand, buckle and delaminate. This degrading plywood has an ill effect on the roofing, including reduced nail holding power, wind damage due to an uneven deck and stress cracks due to unstable decking materials. So you can see why turbine ventilators should never be covered up in the winter.
  

Nothing brings more spectacular part in the feel and security of your house than roofing and siding. They are the substantial visible factors of your house, and they are the number one thing people recognize when they stop or pass by your home. They are as well your primary protection against rainwater, snow, wind and inclement weather.
