Homeowners often underestimate the importance of attic ventilation as part of a roofing system. Effective air ventilation is not only crucial to protecting the attic but also the integrity of the entire roof. On top of all of this, homeowners also have misconceptions about how this ventilation works after installation. We are here to debunk the following most common misconceptions to clear up any that you may have on this important roofing feature.

Misconception: The Installation of Roof Vents Automatically Provides Adequate Ventilation for the Attic

The truth is that all roof vents are suitable in every type of house. For example, cost-effective ridge vents do not work efficiently without baffles to keep the air out of the attic. You need to have both or the ridge vents cannot perform their function at all. Gable vents are effective at circulating air but only in a small area. If your attic is large, you may require too many of them to perform the job efficiently. Most professionals recommend the ride-and-soffit continuous systems for home for the best efficiency with roof ventilation. Of course, each house differs so you need a personalised analysis to know the perfect route to take for your home.

Misconception: Roofing Ventilation Systems Are Only for Warm Climates

Another misconception is the roof vents are only effective for warm climates to provide high thermal performance. This is not the case since roof ventilation is only a small part of the energy efficiency of a roof. The efficiency also depends upon the insulation, colour of the roof and the amount of direct sun exposure. Ventilation is important for the attic regardless of the weather not just for thermal performance but also for moisture control to prevent damage. Without proper air flow, moisture can build up in the attic and cause damage in the roof support system that can even lead to rot in severe cases.

Misconception: The Higher Number of Vents, the Better the Ventilation is in the Attic

At times, homeowners think that if they add a lot of vents to their roofs it will improve their ventilation. The problem with this belief is that too many vents allow places for roof penetrations and also increase the risk for leaks. There is no need to overdo on the number of vents. Only add the number that a professional advises you to do for your specific situation.

When facing a roof replacement project on your home or building, cost is a major consideration if you are like most other property owners. The actual cost depends on so many things, including the type of roofing materials, how much labour the roof replacement requires and any unexpected issues. While you may think it is impossible to stay on budget with this type of project, we are here to help you accomplish this with the following five tips.

1. Consult with a Reputable Roofing Company

Many times, property owners turn to a roofing company only after they have gotten frustrated trying to figure the cost of their roof replacement. Actually, this is the first step you need to take and make sure the company that you consult with is a reputable one. A professional from this company will meet with you to provide you with an accurate quote so that you can figure your budget prior to hiring the company. You should only hire the roofing company after you are sure that it will stay within your budget as much as humanly possible.

2. Learn If Your Property Insurance Will Help Pay the Cost of Your Roof Replacement 

In some cases, property insurance will pay at least a portion of the cost of your roof replacement if not all of it. It depends on why you require the replacement. Storm damage is one cause that the insurance might cover.

3. Research into the Various Roofing Materials to Decide Which One Suits Your Budget the Best

Consider all of the roofing materials that the roofing company has to offer you. While the top of the line may be out of your reach budget wise, the company may have a less expensive one that still is high performing and durable. Communicate your budgetary constraints in clear terms, and this will let the roofing company offer you the right roofing material for your budget.

4. Plan for Unexpected Expenses

Always plan for unexpected expenses. As the roofers from your chosen company work on the prepping the roof for the new materials, they may uncover issues that require addressing before they can proceed.

5. Look into Financing Options If Necessary

Another way to stay on budget is to look into affordable financing options. You may qualify for a loan of some type to stretch out the cost of the roof replacement over time.
