6. Recently we have noticed some water spots and a few damaged shingles on our roof. Are these signs that we should consider roof replacement?
Signals of an aging roof that is potentially in need of replacement include: Missing granules on the shingles, torn or missing shingles, mold and deterioration around the flashing and chimney due to poor ventilation and trapped moisture within the layers composing the roof, and high utility bills, simply because the consequences of age-related roof damage can lead to a compromise in the efficiency of the air conditioning and furnace systems. If you have noticed these signs then don’t wait to call your local roofing contractor for an immediate inspection.
7. Can damaged or worn out flashing be an issue I should be concerned about?
A roof’s flashing is important because it’s the only barrier between the openings and joints of the roof protecting them from the outside water and moisture; in other words, a roof without a properly installed flashing system (or a damaged one) is extremely susceptible to exposing a home to mold damage, as water can travel through and underneath openings in the roof if they are not appropriately sealed and protected. If you worry about the condition of the flashing on your roof, again it’s best to call your contractor before taking any steps by yourself.
8. Should I be concerned about the presence of frost on the tips of the nails sticking throughout the sheathing in my attic?
The reason for the frost on the nails is because the warm moisture from your home is seeping into the attic and condensing on the steel, which indicates that your insulation could become compromised due to that moisture, often resulting in mold. To combat this problem, be sure to seal all of openings letting air into your attic including all bathroom fans and attic openings such as pull down stairs. You can also reduce overall moisture levels in your home by always using exhaust fans when cooking and using the bathroom. Attic should also be outfitted with effective ventilation, not just fans.
9. My roof is made up of cedar shakes, should I be using a fire-resistant treatment to protect against fires?
When it comes to prolonging the life of a cedar roof and protecting it from fire, your main concern should be to keep your roof clean and free from debris. Don’t worry about treating with a fire-retardant as all cedar shakes are required to be manufactured with a permanent treatment to resist fire. If you are set on applying some type of weather protectant to help
preserve your roof, at the very least you should consult with the manufacturer of your roof to make sure you have the right product.
10. My roof already has a minor leak in it-what should I do until my contractor shows up?
First, minimize interior damage and damage to the ceiling by eliminating the built up pressure caused by the leaking water. Simply locate the wettest spot on the ceiling and poke a small hole in the center of the bulge and then collect the draining water with a bucket or trashcan, depending on the amount of water. Investigate the origin point of the leak.
The point at which the water is leaking into the interior of your home is not necessarily where the leak originates so you will need to trace the path of the water to the source. Keep in mind that water will travel down the trusses and beams until it finds a weakened area through which is can penetrate. Roofing cement or tape can be used on the inside of the roof in the attic as well as on the outside, while a temporary repair like a tarp, for example, would be used to cover the leak directly.
