Summer is a season characterized by people leaving their houses and going on short vacations to unwind. Families usually visit a beach during their vacation in order to spend their time under the sun and forget some of their problems, which might include their home’s poor ventilation system. Family members, especially those who rarely use the attic, could easily disregard the effect of a poor ventilation system to a house’s roof.

There are five common roofing problems that stem down from a poor ventilation system. The one fool-proof way to avoid all of these is to ensure a proper ventilation system is installed in your house. Check out the list to see if a problem started or is already manifested in your house.

Five Common Ways A Half-Baked Ventilation System Is Hurting Your Roof

1. Rotting Of Roofing Materials
The rotting of roofing components and materials is one of the most common problems derived from a poorly ventilated home. Not only does it cause rotting in the roofing material, but it also causes decay in both the roofing deck and the support beams. Although this will likely happen during the winter or during the rainy days, a hot temperature can also decay the roofing materials.

What causes this is the excess heat inside the house. Because of the badly installed ventilation system, instead of dissipating excess heat and moisture, both are trapped in the roofing of the house. This could shorten the years for replacement of the shingles or other roofing materials.

2. Sagging Of The Roof Deck
The roof deck is the place where the structural components, insulation, and the weatherproofing layers are placed. A roof deck is the backbone of a roof system and is the one responsible for the shape of the roof. Because of the moisture and heat that seeps and breaks the adhesive in the deck, it will appear to become saggy or spongy. This is not a good thing for a roof deck as it is the one responsible for the shape of the house.

3. Rusting On Nails And Other Structural Metal
When metals in the roofing (such as nails and fasteners in the roof)are exposed to moisture, the metal will start to rust. In the long run, all the heads of nails in the roof will surely rust, and it can endanger anyone who will be working on the roof. After nails and fasteners, rusting will surely happen on more important fixtures such as the structural metal. This summer, a lot of people might find their metal roofs corroded.

4. The Shingles Problem
Shingles are one of the most expensive roofing options because they can withstand high temperatures compared to others. Even on the hottest summer days, the asphalt present in each shingle is enough to absorb temperatures of 150 degrees and above. However, if these shingles are both exposed in heat from the inside and from the outside, as well as the added moisture that comes below the house, even shingles will have a short lifespan.

5. Mold And Mildew Formation
A poorly ventilated house is very problematic when it comes to the moisture that rises as the temperature becomes hotter. Instead of getting outside the house, it will stay in the roofing, which can cause mold and mildew formation. Mildew and mold are both fungi that destroy organic matter such as wood, paper, or leather. In addition, these fungi also produce a very offensive odor that can cause ailments to humans, especially those with lung conditions.


What Causes These Problems?


The moisture that usually causes these five problems happens when condensation appears. Condensation is the product of warm and moist air touching a surface that is colder than its dew point. As the accumulated water in the air started to cool down, it releases moisture in the form of water, which then seeps through the roofing. This only happens when the house doesn’t have a proper ventilation system.
