Danger signals of a poorly installed roofing system don't have to appear only on the roof or ceiling. For example, poor attic ventilation can result in excessive moisture which leads to blistering and peeling of exterior paint.
A faulty roof structure poses a threat to both the home and its occupants. Water damage, mold, and rot are just a few of the risks associated with a failing roof. In this section we are going to identify a variety of different problems associated with roof damage and defects.
Leaking is obviously one of the most common signs of a failing roof system, You often see these signs in an attic after a heavy rain. The leaking may be caused by inadequate underlayment or deteriorated flashing. Another leak indicator is the appearance of stains on interior ceilings and walls. These leaks are often caused by ice damming, which forces water under the shingles at the eaves.
Sometimes a roof can naturally reach the end of its useful life without experiencing a roof failure. It just looks old and worn, and you are doing preventive maintenance on your home. If replacing an old roof is delayed, however, it could result in bigger problems down the road. So watch for the warning signs to be sure to give yourself plenty of time to add the project to your TO DO list.
Potential signs that your roof may need to be replaced:
Shingle edges are curled or shingle tabs are cupped
The roof is old and worn
Dark streaks. Airborne algae cause dark streaks on roof decks. While this may not necessarily harm the roof shingles, it may not look good.
Moss. Moss can grow on roof surfaces that don’t get much sunlight especially in cool, moist climates. Moss growth can be more than a cosmetic issue. Moss holds moisture against the roof surface and overtime in freezing climates can cause damage to the granules on the top of the shingles.

The GacoProFill SYSTEM is the first complete spray foam system to offer a consistent cavity fill and a smooth surface with no trimming needed.
The self-compressing characteristic of this tough, true polyurethane based spray foam is the reason GacoProFill can be quickly and easily installed behind a membrane (either GacoProFilm or GacoProWeb) as part of the GacoProFill SYSTEM.
Because there is virtually no waste, the GacoProFill SYSTEM provides higher yields than most open cell foams and scrap disposal expenses are greatly reduced or eliminated.
