Visually inspect your roof from the outside. If you see any of the following you will want to have a professional roofing contractor inspect your roof:
Inside your house, look for water damage in ceilings and walls. Don’t forget to look in closets and the attic. Water damage is often first seen around ceiling vents and light fixtures. Soft spots and discoloration in drywall, plaster or wallpaper may also indicate moisture inside the walls. Unseen interior damage behind walls may remain unseen for many months or years resulting in substantial damage and repair costs
You may not want to wait until your roof gives you problems. After all, your roof protects everything you own. If your roof is over 15 years old it may be time to re-roof. The life of your roof is dependent on many factors including the quality of the original installation, the proximity to trees, regular inspection and maintenance of your roof, and the type of product originally installed. Keep an eye on the appearance of your roof or call a qualified roofing contractor to make a professional assessment.
Your home needs to breathe and ventilation in your roof and attic system are an important part of a safe and healthy home. Our building code stipulates one vent for every 300 square feet of roof.
Moisture from everyday living (showers, laundry, dishwashing and cooking) needs to escape from your house to prevent mold, mildew and the rotting of your attic wood.
Summer heat needs to escape so your home does not become unbearably hot. Winter heating also needs to escape from attic spaces to prevent ice damming. (Ice dams are the large mass of ice that collects on the lower edge of the roof or in the gutters. As more melting snow runs down the roof, it meets this mass of ice and backs up, sometimes under the shingles and into the attic or the house.)
