Danger Signals of a Failing Roof

Sep 12, 2016

J&B Construction encourages homeowners to keep a close eye on their roof and learn how to spot problems before they severely impact the home. “Look for the following signs to determine if it’s time to replace your roof,” advised Scott Cline, owner of J&B Construction.

  1. A leak in the attic. After a strong storm or wind-driven rain, take a look in the attic for signs of leaking. “Ice damming can also cause water to enter the house if you don’t have an adequate shingle underlayment or if the flashing (the aluminum or steel used over roof joints, like chimneys and pipes) has deteriorated,” Scott said.
  2. Blistering or peeling interior or exterior paint. When paint starts to peel off, the cause is likely trapped moisture in the house due to excessive temperature or high humidity from poor attic ventilation. The air in the attic needs to flow freely from the soffit to the ridge to reduce humidity. Make sure there is a vent in areas such as the kitchen or bathroom, plus dryers should vent outside.
  3. Stains on interior ceilings and walls; mold or mildew growth. “If you see stains or, even worse, mold growth inside your home, it may be caused by inadequate or faulty shingle underlayment that is allowing water to seep into the house,” Scott said. “Inadequate ventilation could also be the culprit, which causes excessive moisture— conditions in which mold and mildew thrive.”
  4. Exterior decay, sheathing, and/or siding. Poor attic ventilation is again a possible cause, but any condition that results in excess moisture can contribute to decay. One way to combat the problem is to put a vapor barrier between the insulation and the inside of the house, which can reduce the amount of moisture that goes into a wall and help the moisture escape from the wall.
  5. Missing, cracked, or curled shingles. “If you see that your shingles are dry or practically break when touched, that means they have reached the end of their useful life and it’s time to invest in a new roof,” Scott said.
  6. Dark, “dirty-looking” areas on your roof. This could mean your roof has vegetation, fungus, mold, or algae growth, or that the shingles’ protective granules have been lost. This doesn’t mean you need to replace your roof, but these stains can reduce curb appeal. Cleaning the shingles is an option, but that could shorten their life.
  7. Excessive energy costs. A possible cause of higher cooling costs could be insufficient attic ventilation, requiring the cooling system to run excessively. “In warm weather, inadequate ventilation will trap hot air in the attic, causing air-conditioning systems to work harder, or leaving your home’s interior hotter and less comfortable,” Scott said. “In both hot and cold weather, moisture in the attic can become trapped and condense on the rafters if it’s not insulated properly. This moisture can drip down onto the insulation and reduce its effectiveness, potentially increasing energy costs.”

 The only complaint I have is when I have J&B do my roof in another 30 years or so, is Dave their sales man (a great guy) would not guaranty I could get the same great crew I had this time. They did a fantastic job. Much better than the last roofing company did. A nice bunch of guys. Did a very nice job cleaning up. I'd give them 10 stars but 5 is the limit. If you need a roof done this is the company you want to do it. One more point I need to make. The guys that did the chimney flashing are artists. I went up on the roof when they were done and was very pleased with not only the roofing job but the sculptured sheet metal work. It's kind of a shame it's on the roof and not hanging on the family room wall :). You get the point. Hire em. You'll like em. 
 We live in a historic designated neighborhood and recently had our 30 year wood shingle roof replaced with another wood roof and new gutters. From Day 1 of the project to the final day, the entire team was responsive, professional, and very competent. When some minor changes were proposed by us they quickly and effortlessly complied. After going through this experience with J&B, I would highly recommend them to anyone considering a roof and gutter replacement, whether it be a simple or complicated project. 
 J & B did an amazing job from start to finish. The initial meeting at my home took place exactly at the time that was agreed upon and Scott was thorough in his explanations and transparent about costs. When the time came to begin the project, the team that showed up was friendly, professional and timely in getting the project done. The cleanup afterward was such that it looked like they hadn't been there at all. The roof looks great, there were no surprises and Scott came by to inspect the work and explain the warranty upon job completion. I would highly recommend them.
