Frequently Asked Questions
What is a range hood roof cap or roof vent?
A range hood roof cap/ vent is an accessory that covers a vertical running duct system leading from the range hood and terminating above the roof. The purpose of this cap is to prevent debris and critters from entering and blocking the vent while still allowing proper airflow.
Is it better to vent the range hood through the exterior wall or the roof?
According to experts venting through the roof is better than venting through the wall. The hot air rises, so it helps throw the exhaust fumes outside more easily. However, it is not mandatory. If you cannot vent through the roof for any reason, venting through the wall is a viable option.
Should a roof vent have a cap?
The roof cap is essential for preventing foreign objects from entering the vent duct and affecting the efficiency of the range hood. Also, putting a cap on the vent eliminates the need to clean and maintain the ductwork more often. Moreover, it also prevents rain and snow from falling inside.
How do I know which roof cap size will suit my range hood?
As a general rule, the roof cap size should match the diameter of the vent duct. For example, for range hoods with up to 400 CFM, the allowed duct size is 4”, so a 4” roof cap will be suitable. The following table will help you find a suitable roof cap size for your ductwork.
|Range Hood Size||Allowed Duct Size||Suitable Roof Cap Size|
|Up to 400 CFM||4”||4”|
|1200 CFM and above||10”||10”|
Things to consider when buying the best range hood roof cap/roof vent
It can be tempting to buy the first one you come across at the local hardware store. But if you want to avoid regrets later on, take the time to think about your purchase before you commit to anything. Here are some essential things to consider when buying a range hood roof cap or roof vent.
Size is the most vital consideration. No matter the quality, price, or other specifications, if the roof cap size is not correct, the roof cap will be useless. Make sure that the size of the vent matches up with the size of your range hood ductwork. If not, there’s no point in buying it.
The roof caps or vents have a wide range of styles and features. Knowing your budget will help you compare different designs and brands within that range and select a suitable accessory at a reasonable price.
Roof caps or vent roofs with better design have better chances of performing the duties to the optimum level. A good roof cap design will ensure that debris or small animals can’t enter the ductwork. It will keep the vent open for proper airflow and let the range hood exhaust the kitchen air efficiently.
A product’s construction material determines how durable and long-lasting that product will be. Generally, low prices are associated with cheap-quality products, while high prices mean the product has better quality. However, it is not always true. A product can be inexpensive and durable also if it doesn’t have additional features. Select a product that fulfills your basic needs and is sturdy enough to last years.
Trusted brands have better customer service and warranty giving you more value for money. Range hood roof caps and roof vents are not very technical items but buying a high-quality product from a brand known for its quality will ensure that you won’t have to replace it again and again.
