Lafayette Roof Pros provides professional roof ventilation in Lafayette, LA for residential and commercial properties across Acadiana. This is the page the rest of the site reasons from. In Acadiana an attic is a machine for making condensation unless somebody designs it not to be, and most of the ventilation on most of these houses was installed by reflex rather than by calculation.
The rule is balance and the arithmetic is simple. Code permits a 1:300 ratio of vent opening to attic floor where intake and exhaust are split evenly, and demands 1:150 where they are not. On a 1,500 square foot attic that is five square feet, half of it belonging at the eaves. Exhaust without matching intake does not ventilate; it turns your ridge vent into a device that drains conditioned air from the house.
Blocked intake is the defect we find most often, and it is almost always invisible. Blown insulation drifts over the eave and plugs the soffit from inside, or somebody rolled paint across perforated vinyl panels, or the original builder installed continuous soffit board with vents only over the porch. The fix is baffles at every rafter bay and real open area at the eave, and it is inexpensive compared to what it prevents.
We argue against powered attic ventilators and will not install one. A fan that moves more air than the intake can supply depressurizes the attic and draws makeup air from the conditioned house below, so you pay to cool air and then throw it away. In humid weather it can also pull outdoor air with a very high dew point across cool duct surfaces, manufacturing the exact condensation the fan was sold to prevent.
Mixing exhaust types causes a quieter version of the same failure. A ridge vent working alongside open gable vents will simply pull air in through the gables and out the ridge, short-circuiting the eave-to-ridge path entirely and leaving the lower two-thirds of the deck without airflow. When we install a ridge run we close the gables, and we tell homeowners why before we do it.
For houses with the air handler and ductwork in the attic there is a better answer than any of this. Seal the attic at the roof deck with closed-cell foam, bring the space inside the thermal envelope, and the condensation problem disappears because the humid air never gets there. It costs more, it requires the shingle warranty to be checked first, and on the right house it is the correct recommendation.
Our licensed and insured team brings the right materials and equipment to every job — synthetic underlayment, 8d ring-shank sheathing nails, continuous ridge vent, net free ventilation area, Galvalume standing seam panels, closed-cell spray foam at the roof deck — and backs the work with a written workmanship warranty. We serve Lafayette and nearby communities including Broussard, Youngsville, Carencro, Scott.

Materials, equipment and how we do roof ventilation
The difference between roof ventilation that lasts and roof ventilation that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with synthetic underlayment, 8d ring-shank sheathing nails, continuous ridge vent, net free ventilation area, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Lafayette job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in Acadiana means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
