It could never be stressed enough exactly how essential air flow is to your durability of one’s roof and exactly how energy efficient your home is. If you would like get whatever you can from your own roof then your first rung on the ladder is to check if you’ve got enough air flow. The appropriate number of airflow through your attic will accomplish multiple objectives when done correctly could have a return on investment.
Through the summer, heat will increase to the top of your loft without a real way to dissipate. That not enough airflow will cause hot moist atmosphere to increase and accumulate. If that dampness cannot escape it collects and certainly will affect studs, insulation, roof anything and decking else within the loft. For those who have shingles with nails popped then that is normally an indicator of bad airflow. Add in some winds that are heavy you will be losing shingles or at least those shingles is going to be compromised. With no stability of cooler atmosphere flowing in and warmer air flowing out of the possibility of a buildup of mildew and mold could occur. This accumulation of fungus could affect the health of your family members and if it gets out of control could be high priced to alleviate. Then it could be because of the amount of heat that is leaking into the house from the attic if you think that your HVAC system is working too hard. Heat rises however when its rising against an envelope of warmer atmosphere than it settles. It settles back in your house causing your air conditioning equipment working harder and longer which produces higher energy usage.
Through the cold temperatures, the problem with moist atmosphere rising, as stated above, is exacerbated because that warm damp air will condense on cool surfaces. Rotting insulation, rotting wood, and fungus are all exaggerated but winter does present other unique complications. Bad ventilation causes warm moist air to collect towards the top of the attic. The blend of that and the warmth of this sun on the top will melt the snowfall which operates down the roof to freeze once more during the eaves. This period produces ice damming. The ice damming will force melted water up under shingles and drip behind siding rotting out roof decking and dripping into your home. The leakages are seldom noticed right away as well as the beginning could be difficult to get also for an expert roofing contractor. 1000s of dollars of damage can have happened ahead of the drip is even noticed.
If you are not sure your loft area is properly ventilated then you should call a roofing contractor and have it checked. The cost for such an inspection is minimal if not free. The cost to correct or replace a roof or fix the damage from water leaking into your house might cost you thousands.
