For this reason, to eliminate mildew or mold problems caused by excess moisture and other causes that will affect the lifespan of a housetop covering it is essential to learn some of the requirements. Thus, roof ventilation is essential.
Importance
About how moisture and heat can get trapped in attic spaces, damaging sub-roofing as well as shingles it is vital to be concerned and aware of.
For instance, insect damage, rot, severe structural damage and major condensation even may be encountered in a cathedral type ceiling without underside sheathing and adequate passage in the soffit.
It is crucial to ensure adequate air passage through the attic space for such type of ceiling design. At the eaves between every set of rafters soffit air passages that are blocked by insulation can simply be corrected by installing soffit vent baffles.
Consequences
The following unwanted problems could result by not having proper exhaust and intake systems in the structure:
- Moisture Damage - When the building already has an interior moisture problem rot and mold problems are more likely to arise. Especially if in an attic lacking proper or any vents that moisture is trapped, this happens.
- Higher Energy Costs - Increased cooling and heating costs may occur as any attic without proper exhaust and intake systems. By placing good insulation between rafters to allow good flow and converting those spaces to a "conditioned" space will greatly decrease energy bills.
- Structural Damage - mold infestations or worst, costly damage to the structure can occur from hidden leaks from the outside into the roof cavity and using water-resistant foam products for insulation.
