  • Add a second floor to a house -- in 3 days!

    For years we have had factory built homes where the entire home was built in a factory and then trucked to a site and put on a foundation, much like a mobile home. When people wanted larger factory built homes, they started making them in two halves, to fit on the trucks, and stuck them toge...

  • Roofing Ice Shields

    "I would like to ask your thoughts on the "pros and cons" on the use of the self-adhesive, 3 ft wide membrane (ice dam) used on the edge of the roof line. I believe that this would replace the felt paper, under the 1st rows of asphalt shingle. We have a sloped roof, but I do not know how ste...

Until the late 90's they actually didn't do much more than camouflage a dying leaking roof -- the problem being that things move up there from full sunlight to cold nights, from hot summers t...
  • the potential damage of ice dams

    Ice Dams are created when heat from the house gets into the attic and manages to melt the bottom of the snow pack. This melt water flows down to the edge of the roof where it is now freezing cold and you get ice dams or ice cycles. Ice dams back water up behind them and this finds it way under ...
  • CONFUSION: POWER ATTIC VENTILATORS ARE NOT RECOMMENDED FOR WINTER USE. WHY?

    The main reason for not recommending power vents in the attic is that the attic is usually not well sealed, and the power vent, in sucking air out of the attic, creates a negative pressure in the attic. This negative pressure sucks warm air and humidity through the ceiling leaks into the att...
  • New rain gutters with a built in leaf guard.

    Leafs and other debris clogging up the rain gutters can be the death of a roof. On a one story bungalow you can pretty easily keep those gutters clean but when things are higher up, or you have a lot of mature trees in the yard, it can be a big maintenance task. If you have tried any of the scree...
  • I have ice dams over a bay window.

    Sol, from Sudbury, Ontario, has terrible ice dams, as you can see in the photo. They are directly over his bay window. Take a good look at the house design. The bay window comes right out to the edge of the roof, preventing any possibility of any ventilation up over this area. In addition, be...
