There basically are three kinds of roofing “leaks” that are explained below. The answer to moisture issues on your roof depends upon what kind of “leak” it is. If you happen to see an excess of moisture within extreme changes in temperature, and not as it rains, the moisture likely is not a roofing leak.
The 1st kind is in which water is leaking through the roof system while it’s raining. It might involve leaks caused by deteriorated or damaged shingles, improper shingle installation, or failed/poor flashing details at walls and penetrations. It might even be because of damaged window sills, incorrect siding installations or serious wind-driven rain. These are exterior leaks which usually can be repaired and inspected by a roofer.
The 2nd kind of “leak” is caused by an ice dam. This isn’t workmanship associated. The best method of preventing or reducing ice dams includes eliminating or reducing the quantity of hot air that’s escaping inside the attic and melting snow on your roof to the point in which it causes ice build-up that looks like glacier-like. One other temporary option includes removing the snow from your roof before it turns into ice and penetrates your roof system.
The 3rd kind of “leak” is caused by frost or condensation buildup in your attic. This isn’t workmanship associated or roof leak. In order to prevent condensation and frost from forming in the attic, you have to reduce or eliminate the quantity of air leakage into your attic and improve ventilation and insulation to permit damp air to escape your roof.
Warning Signs of Condensation inside the House
Skylight and window condensation is the result of an excess in-house humidity. And the glass just offers a noticeable cool surface upon which humidity may condense. This might be an in indication that your excess interior humidity is causing damage somewhere else in places you can’t see, like your ceilings, walls, floors, and the attic roofing. Excess interior humidity may cause peeling and blistering paint, rotting and warping wood, and formation of mold and mildew.
In extremely cold temperatures, frost may build up upon the underside of your roof sheeting. As the exterior temperature increases, the frost melts and may resemble a leak. The “leak” may be excessive as the temperatures significantly change, as is typical during our winters. Build up of frost is most typical above heat sources like kitchen stoves, light fixtures, bathrooms, fireplaces, fans, and incorrectly vented exhaust fans. As the frost melts, the “leak” is most typically discovered dripping out of these heat sources.
Cathedral ceilings and high ceiling beams that have water spots may be confused with an active leak, when indeed it’s a result of condensation.
If you’ve ever seen a ton of icicles hanging from the corner of the roof, odds are your home is leaking substantial quantities of heat and air into your attic.
