We are living a lot better than our ancestors 100 years ago, thanks to heating and cooling in our homes. However, with these advances in technology comes more complications in the building industry.
With advances in house wrap, siding, windows, roofing materials, and wood manufacturing, we cannot build things the way we used to. The way builders built homes from the 1800’s till the year 2000 was to allow the homes to breathe.
Homes Built Before 2000
On homes built before the year 2000, the biggest issue we see in homes is the use of newer roofing materials. The attics are producing condensation at a scary pace; now more than ever, homes have large ice dams and water leaks during the winter months. Your attic should be the same temperature as the outside temperature. However, with today’s heating and cooling technology, an attic that is not insulated properly, you have hot meeting cold and cold meeting hot!
This process creates condensation in your attic and ice dams on your roof.
You can expect from an improperly insulated attic:
- Decreased shingle life: 25-year shingle decreased into a 12-year shingle
- Drywall replacement
- Higher heating and cooling bills
- Eventual replacement of your roof decking
- High monthly utility bills
Therefore, every time we design a roof system, we make sure you know what is going on up in your attic and bid accordingly.
You may ask, “If you know that this is an issue, why would you use the newer materials that cause these issues?” The answer is simple, we are required to follow state and city codes that demand you use these materials.
Spray foam is the only type of insulation that when installing properly, it can solve all of your problems in the attic.
