Here we are in the midst of another cold general contractor Massachusetts winter and like every winter here in New England many property owners will have major issues with ice dams causing roof leaks and shingle damage.
Although it may seem as though ice dams are an unstoppable force of nature, they are actually quite preventable. Attics and cathedral or vaulted ceiling areas that have been correctly incorporated into the overall building envelope don't have problems with ice dams and icicles in the cold seasons. Through the use of proper insulation and ventilation techniques ice dams can be stopped cold (pun intended).
Here a typical scenario for the formation of ice dams:
A house has a build up of snow on the roof.
The temperature outside is below freezing.
The temperature inside the attic is above freezing, thus raising the temperature of the roof itself to above freezing.
Because of the warm roof, the snow on top of it begins to melt from the bottom up.
This melted snow water tries to run down and off the roof.
As soon as the water reaches the edge of the roof it gets exposed to the freezing air.
The water refreezes as ice instead of snow in the gutters, if present, and along the edges of the roof.
As more and more melted snow water continues to run down the roof it just keeps freezing behind and on top of the previously frozen run off, forming a bigger and bigger ice dam.
So How Do Ice Dams Cause Roof Leaks?
The melted snow water doesn't immediately freeze anymore after the ice dam has begun to take shape. Once the ice dam has built up a bit it literally creates a dam that traps the rest of the water trying to run off the roof behind it. While this trapped water will eventually freeze, it may take a while and during that time a portion of the shingles on this roof, behind the ice dam, are basically submerged in water.
Now of course your roof shingles are obviously suppose to protect your home from the weather i.e. rain and snow. However, general contractor Massachusetts most roofing materials are not meant to have a pond or river on top of them.
So What Can You Do To Prevent Ice Dams?
First and foremost you must recognize that proper insulation and ventilation is the key(see image on right). If we are talk about an attic area then typically this means that the insulation needs to run up the walls of your house then over the attic floor joists forming an ideal insulation envelope. In the attic scenario only the floor of the attic should be insulated, not the underside of the roof!

Dear men/ womens,
উত্তরমুছুনMany people are interested in increasing their storage space or creating a new feature for the exterior of their property. Sheds are popular choice as they are extremely versatile. However, those who have little DIY experience worry about siting their new shed and constructing sturdy base. This need not be stressful as building a base for your shed is actually quite a simple task which is usually easy for one person to complete.
