More Facts About Roofing

1.  All types of shingles last longer with proper roof ventilation.
2.  All shingles roofs installed without proper ventilation will immediately loose their warranty.
3.  The most common and effective type of ventilation today is Ridge/Soffit vent combo. Soffit or eave vents are for the intake of fresh air, and ridge vent is for exhaust. A properly designed ventilation system should allow more air to enter than to escape.
4.  Other, less efficient roof venting systems include gable vents, static box vents and electric powered vents.
5.  Different types of ventilation should never be combined on the same roof. This is because different ventilations create a short-circuit affect, when hot air circles around the attic space, but never leaves from the exhaust, thereby nullifying your ventilation.
6. If you have attic insulation installed, make sure it does not block soffit air intakes. Otherwise, the roof ventilation will not work.
