Roof Vents Roof vents are extremely important when it comes to attic ventilation. In the summer, roof vents will reduce the air temperature, which reduces air conditioning, and in the winter they reduce the humidity level of the cold air, which in turn reduces costs for heating. Roof vents are available in many styles and materials. Installing vents on the roof allows outside air to quietly pass through the intake vents and into attic space, which rises up through the roof vents. This becomes particularly important during warmer months when the attic of the home can become extremely hot. The heat build up in the attic increases the temperature in the house making the air conditioner work harder. This build up can also result in expensive repairs to the roof from cracking wood and premature aging. The roof vents allow increased fresh air exchanges, lowering utility bills and cooling down the house. The most common roof vents are manufactured in galvanized and painted steel, but can be manufactured in stainless steel, copper, aluminum, and high density plastics. There are also many styles and models to choose from depending on the ventilation requirements of the attic. They Include: Peak Vents, Ridge Vents, and Gable Vents It is important to choose the right roof vent to assure proper attic ventilation. FAMCO manufactures a wide variety of roof vents in plastic (BVDS/FA50) and metal (BK, JV, JVO, CRV, GBV, LRV). Plastic Roof Vents FAMCO plastic vents (FA50 / BVDS) are made from High Density Polyethylene (HDP). HDP is one of the most versatile and widely used plastics available. Outdoor integrity is maintained in all of our plastic products by the addition of UV inhibitors which protect the material from deterioration in sunlight. Our colors are added with stabilizers during the manufacturing process to prevent fading. These vents are resistant to cold, heat and ultraviolet rays. They will not rust, dent, fade or crack and are built to outlast most roofing materials. The vent has a low silhouette with a screen molded in to prevent bird nesting. This product is a standard residential roof vent with fifty square inches of net free area. PBK and GBK Vents The PBK and GBK vents are designed to use with bathroom or kitchen venting systems. These vents come with a damper (to prevent backdraft), with a screen or without a screen (for a roof top dryer vent application), and with or without a stem for flex or hard pipe connections. J Vent The JV is for use on any roofing material. It provides a low silhouette and is open on two sides for better air flow. It helps eliminate moisture and heat buildup. The JV can also be used for hard connect exhaust applications. The J Vent can be produced with several different options – curb mount, larger flange size, tall throat (for greater clearance between base flange and hood for flat roof applications) with a bottom stem and a hood with rounded or pinched corners. The JVO38 is one of the best built and most reliable on the market. It features 38 square inches of open space, insect screen, low silhouette and a removable hood for access to the attic area when needed. It is open on all four sides for better air flow and unrestricted venting to help eliminate moisture and heat buildup. Continuous Ridge Vent The Continuous Ridge Vent (CRV) provides optimal ventilation for the price when used with proper soffit venting, The Continuous Ridge Vent eliminates the “spotty” ventilation found with other types of gravity vents but does not use the power of certain fan vents. The CRV features a low silhouette and weather tight construction. Quality constructed of heavy 28 gauge material to withstand years of hard weather. The CRV comes with end caps and adapters. Globe Vent The Globe Vent (GBV) is an economical gravity ventilator for use on residential, commercial and industrial applications. The GBV features watertight construction and a low silhouette while offering positive draft for good air flow. The draw bolt collar (available in sizes up to 12”) offers secure fit, yet is easily removed when needed. Louvered Roof Vent The LRV50 (Louvered Roof Vent) is a great heavy duty vent for use on pitched roofs. This Slant Back Roof Vent is one of the best built and most reliable on the market. It features 50 square inches of net free area, louvers on three sides, slant back and a low silhouette. This vent works best when used with soffit or gable end venting.

Q. Will dirt collect on a metal roof? A. The PVDF coatings used on quality metal roofs consist of a very tight molecular bond that encourages dirt to wash off of the roof. In most environmental conditions, these roofs stay very clean over the long term. However, while these coatings will not support the biological growth that leads to dark streaks and stains on granular surface and shingle roofs, there are certain environmental conditions which can cause dirt to collect on the roof. The worst situations are in areas with surrounding trees, and this is made worse by trees that lose sap which can stick to the roof and then hold dirt or even support biological growth over time. Additionally, heavy pollen or airborne fungus can land on a roof and stick there. Areas prone to heavy and frequent dew (such as waterfront or near-waterfront properties) can also exacerbate this issue by creating a sticky or gummy coating on the roof. We always tell folks to imagine letting your car sit out in the area of your roof and not washing it. The results on it, over time, will be similar to what will happen on your roof. In some cases, folks like this because it helps the roof to take on a more “woodsy” or “natural” appearance. The resulting grime on the roof, while it can be cleaned by scrubbing or light power washing, will not normally be something that damages the integrity of the roof system or its finish.

Q. Will a metal roof affect cell phone reception inside of my home? A. Chances are that you currently use your cell phone in metal roofed buildings on a regular basis. Think of the restaurants where you eat, the stores in which you shop, your bank, your church, etc. Many of those buildings have metal roofs or metal decks beneath flat roofs. Over the years and tens of thousands of roofs, we have had no more than five people tell us that their metal roof did seem to affect their cell phone reception. If you currently have very, very weak or spotty cell phone reception inside of your home, a metal roof may be the “straw that breaks the camel’s back.” Adding a cell phone signal booster in your house would have been helpful before the metal roof and certainly would be helpful after your metal roof is installed. However, if you have fair to excellent cell phone reception now, the metal roof should not have any noticeable effect.

I have a metal roof (with fasteners) on a 4 / 12 pitch roof. It has a ridge vent as well. As you can imagine, living in Canada where there is plenty of snow and cold weather, the ice build up, especially along the edges is pretty significant. The house has a cathedral ceiling and the metal roof becomes like a grilling skillet, if you know what I mean. The heat that escapes from the ridge vents melts the snow and runs down the roof, eventually solidifying as ice build up. I was wondering if I should install additional vents, in particular “maximum” vent models, in those areas where I know exactly where the maximum heat is accumulating and escaping through the ridge vents. My roof is approximately 900 square feet. How many of these “maximum” vents should/can I install? thank you.

Hi Danny, due to the heat that builds up in summer (and the corresponding skyhigh electricity bills) I’d like to install a power mounted roof vent. I am fairly skilled and do not mind working on the roof. I was just up there and noticed that the roof has ridge vents. I’m wondering whether a powered roof vent would just suck the hot air back in that it blows out of the attic. The ridge vents are small in cross-section and the attic does get pretty hot in summer, so I think that even if the vent sucks air back there is still a benefit. Any advice on this issue? Thanks

Q. Can you install attic vents on a metal roof? A. For most homes, attic ventilation is critical. It helps avoid unhealthy high moisture levels which can result in condensation and even mold. It helps reduce home heat gain and air conditioning costs in warm weather. And it also plays a huge role in avoiding winter rooftop ice dams in northern climates. So, yes, your Classic Metal Roof can, and usually should, be vented. This can be done with our matching Perma Vent or Hi-Flow Vent systems. Also, most commercially available roof and ridge vents can be incorporated into our roof systems as well. Please contact us if you have any questions at all about ventilation or how to make your home more efficient and healthy. When a home is re-roofed, we suggest that all vents be replaced rather than reused.
