Roofing FAQ Continued
Does my roof need to be ventilated?
The National Roofing Contractors Association suggests the amount of attic ventilation be balanced between the eaves and ridge. The intent of a balanced ventilation system is to provide nearly equivalent amounts of ventilation area at the eave/soffit and at or near the ridge. For a balanced ventilation system to function properly, approximately one-half of the ventilation area must be at or near the ridge.
How do I properly ventilate my roof?
Proper roof ventilation requires that air will need to flow from your intake (soffit vents) to your exhaust (ridge vent). The insulation must not prevent air flow by blocking the soffit vent. For exhaust ventilation, ridge vents are commonly used due to the product’s performance and aesthetic advantages. The attic ventilation system must also be balanced between the intake and exhaust vents (2 to 1 ratio, as there are two soffit vents and only one ridge vent).
What do I need to do to prepare for the installation of my new roof?
Make sure to clear your driveway and any items directly surrounding your home. The materials and dumpster will be delivered the day before or the day of the job, so designate a place in your driveway with your project manager. Remove all loose items from walls and shelves, as hammering during replacements may cause enough vibration to shake those items down. Also, please see that electrical power is provided to the outside of your home. If exterior plugs are not available, please run an extension cord through a window or door.
How long will the installation take?
Depending on the size of your roof, most installations take between 1 and 2 days.
Does the roofing company crew clean up the job site?
Many roofers will have a dumpster delivered to the job site. Make sure that the price of disposal is included in your estimate. Some contractors are very fastidious and will clean up the site as they go. Others may wait until the end of the job which can leave your property looking unkempt and can also create a hazard.
How can a homeowner recognize when a roof system has problems?
All too often, roofing system problems are discovered after leaking or other serious damage occurs. Periodic inspections can uncover cracked, warped or missing shingles, loose seams & deteriorated flashings, excessive surface granules in the gutters or downspouts, and other visible signs of roof system problems. Indoors, look for cracked paint, discolored plasterboard, and peeling wallpaper as signs of damaged roof areas.
