Different Types of Roof Vents

Different Types of Roof Vents

The most important part of your home is the roof. It protects you from the rain, the snow and anything else that Mother Nature dishes out. Without it, we are left out in the cold - literally. When building, or buying, a home, it's important to make sure that the roof is in good shape. One of the most important aspects of roofing is adequate ventilation.

Potential Problems

The lack of ventilation causes moisture to build up and possibly cause structural problems with the roof. In addition, ensuring that your roof is properly ventilated will increase the life of your roof and promote the safety of everyone in your home. In addition, built up moisture and heat may cause extra cooling expenses, which raises energy costs. Moisture can also cause ice dams and other problems, including rotting and fungus.

Different Types of Roof Vents & Roof Ventilation

There are various types of roof vents available, including Dormer and Turbine. The most important thing to consider, when choosing one, is the actual ventilation system. Proper ventilation systems will consist of the following two types of vents:

Intake Vents.

These vents will allow fresh air to get into the home.

Exhaust Vents.

These allow air to leave the home.

In order for any ventilation system to work, both intake and exhaust vents must be installed. When properly installed, the ventilation system will allow fresh air to enter the home while sending other air outside.

Calling The Professionals

Dependant upon the area in which you live, a professional roofing contractor will be able to advise you on the different types of roof vents and which is more suitable for your home. Certain types of roof vents are better than others, depending on the roof's structure or style. Cathedral roofs, for example, would require a ridge vent for proper ventilation whereas some homes would be better suited with a turbine vent, which has a free spinning top allowing air to flow out.

Different Types of Roof Vents & Roof Longevity

If a roof is properly ventilated, it can increase the longevity of it's structure. This could save you big bucks in the future by not having to purchase a whole new roof. If a home is not properly ventilated, the moist air has nowhere to go. As it sits inside the home, it will begin to cause damage little by little. Although it may not be noticeable at first, time will show that damage is occurring and, the longer a roof goes without proper ventilation, the worse effect it will have on the structure of your home.

Faulty Furnace Exhaust Vents ... The rest of the story

Faulty Furnace Exhaust Vents ... The rest of the story

In early 1995, the Ministry of Consumer and Commercial Relations (MCCR) has announced a program to replace up to 20,000 mid-efficiency gas furnaces in Ontario, because their plastic vent pipes were prone to errors and could leak carbon monoxide carbon in the house. Other sources have indicated the highest number is 40,000 - but no one knows for sure.

The crux of the problem had been resolved that no other type of vent pipe for use with mid-efficiencyOvens.

Hundreds of homeowners in the program of government, producers and others refused to sue to pay for full replacement. At this time, the owners would have to be about $ 1,000 about $ 1,500 to pay the costs for high-efficiency furnace models that would work safely with the plastic vent pipes currently available. The builder of the house was $ 200, ONHWP pay $ 200, and the gas company for $ 100.

By the end of 1995, nor the Government ofOntario, which approved the faulty vent pipes, nor the manufacturer had made no contribution to the cost of replacement to individuals and businesses. But the government must pay for the replacement of state-funded non-profit housing cooperatives.

It seems that the program has offered nothing for people who had already replaced their mid-efficiency furnaces before this program was announced.

Issued on 12 September 1995, the Ministry of consumer and commercial relationshipsSecurity order requires that all owners of high-temperature boilers plastic fan, to have these systems corrected August 31, 1996. Users and suppliers of propane gas in Ontario were required by law to cease the supply of fuel for equipment that was not corrected within the period. Correction consisted of replacing the faulty exhaust fan with an approved alternative, if available, or replacement of the heating system.

Two vent pipe manufacturer in Toronto, sayswere safe, effective replacement vent lines (a special note of corrosion-resistant stainless steel), that would solve the problem with mid-efficiency installations. These replacement tubes have not yet received approval, and for some furnaces, the replacement was never approved. A manufacturer has asked the Office of the Prime Minister to accelerate some of the millions of ear-marking for furnaces in the government-funded apartments, testing and approval of replacement tubes. The updated output vent pipeSystems typically cost just over $ 400 per home.

At least in theory, all the affected ovens have been installed or replaced, August 31, 1996.

However, private home inspectors will find some of these heating systems still in service, with the original high-temperature plastic vent pipes still in place, later in the summer of 1997. It 'possible that some still exist today. Homeowners should watch out for plastic drain pipes marked Sel-Vent ventingPlexVent or UltraVent. (Or relief other than those indicated in the operation of a high efficiency furnace, ABS, PVC or CPVC, are and are acceptable)

Gas-fitter/installer A license should be consulted if your a mid-efficiency furnace, and you are unsure about the vent pipes on him.

All owners of gas heating appliances should have CO (carbon monoxide) detectors in use and regularly check their equipment.
