I am going to have a new roof put on my house in the next couple of weeks.
OUCH! New roofs are expensive, that is the first thing I learned.
Building codes only allow a maximum of two layers, which my roof already has, so that makes it even more expensive. (Which was the 2nd thing I learned.)
Prices, even between reputable firms vary drastically, it can pay to shop around. (Lesson #3?)
I happened to receive an email on vent problems in a roof from Dave Thomsen Inspections, I thought I 'd include those as well.
As with any other system, roof venting may have been installed incorrectly, may not have enough area, may have been rendered inoperable by changes to the home, or may have been badly modified by the homeowner in an attempt to save energy. Such problems include:
a lack of vents. It is not uncommon to see a complete lack of ventilation. In these cases, the high temperatures within the roof covering will induce a rapid breakdown of the materials. This not only affects asphalt shingle roofs, but also flat and tile roofs that use roll roofing as the primary water barrier. It is also common to find high levels of moisture in these attics, which promotes moisture-related issues, such as rotting sheathing and mold growth.
blocked vents. Very often, inspectors will see instances of poorly installed insulation blocking the soffit and other vents. These should be reported as in need of repair.
false vents. It is all too common to see what appear to be vents installed that are, in fact, not connected through the structure. Inspectors will sometimes see instances of ridge vents apparently installed, but the roofers did not trim back the roof sheathing along the roof's peak to allow the vents to actually work.

I have vents currently, but all the roofers I obtained bids from are increasing the number of vents. |
The inspection on one of my last sales revealed possible mold in the attic due to the bathroom being vented into the attic instead of outside. The listing agent indicated she had found that on several homes built by a particular builder. YIKES
So keep a good roof over your head, ya hear!
