Waukesha Roof Repair provides attic ventilation upgrades to ensure that your roofing system meets the minimal standards of recommended attic ventilation.
Proper attic ventilation is tantamount to the life and integrity of all roofing systems, and proper measures should be taken to ensure that your roofing system has necessary air flow to accomplish this. Below are some of the attic ventilation options that are available.
Ridge vents require no electricity to run, only the natural flow of air. Ridge vents are highly effective in cutting energy costs and prolonging roof life.
Installed along the length of the ridge line and underneath ridge cap shingles, a ridge vent system properly ventilates the entire attic. Fresh air enters the attic through soffit vents located beneath the eaves of the roof. The air moves through the attic and exhausts out through the ridge vent.
Ridge vents are one of the most popular and aesthetically pleasing ways to ventilate your attic by completely and continuously bathing an attic with fresh, cooler air.
Essentially there are two variations of ridge vent available, rolled and solid.
Rolled ridge vent.
Probably one of the most popular styles of ridge vent due to its lower profile and affordability, rolled ridge vent is one type of attic ventilation. Although it does function okay, the lower profile lets less hot air escape and could serve to defeat the goal of ventilating the attic sufficiently.
Further, because of the nature of the material it has little rigidity to withstand being crushed. As such, many times when the rolled ridge vent is installed the roofer nails the cap shingles too tight, thereby crushing the material down and restricting air flow even more. Although this product does serve some purpose and is more economical, my personal recommendation is the solid ridge vent style.
Solid Ridge Vent.
As noted above, solid ridge vent is made from a rigid plastic material and allows maximum air flow from the attic to sustain integrity of the entire roofing system.
Although solid ridge vent is more costly than rolled ridge vent, this style vent will not get crushed due to its structural design. Similar in appearance to the rolled style vent, solid ridge vent has a smooth, clean appearance that is appealing.
Ultimately solid ridge vent gives you more bang for your buck and is likely to last the life or your shingles.
Static (hat) Vents
This attic vent is by far the most popular style vent that is seen and utilized in the Midwest.
Installed approximately 12-18 inches below the roof ridge, hat vents are efficient and allow excellent air flow at a very affordable cost.
The only notable down side to this style vent is that in more cases than not this style static vent is often host to bees nests due to the design; which offers maxim protection for these stubborn pests.
Although it is rare that the bee nests will completely obstruct the entire vent opening, it can be problematic if there is infestations in numerous static vents and the air flow is substantially restricted.
Some attics cannot be ventilated sufficiently by gravity or wind-assisted methods. In these situations the power vent is necessary for moisture and temperature control.
Power ventilators have the advantage of providing good ventilation even when there is no wind. They also provide limited attic temperature control when installed in conjunction with a thermostat. However, most power attic ventilators only have a thermostat, so they only monitor the heat in the attic. Moisture buildup can also be a significant problem so the solution is a power attic ventilator featuring a combination thermostat/humidistat.
