Should You Repair or Replace Your Roof?
Nov 29, 2017
A roof is considered the most important part of a house. Having a roof over your head is actually considered basic shelter, that is why homeowners should pay extra attention to the condition of their roofs, and inspect them once a year at least, as well as before and after a major storm, hurricane, or troublesome weather.
If not ventilated and insulated properly, air can become condensed, especially in attic spaces. Condensation happens when warm indoor air hits a cold surface. It might not sound like a big problem, but condensation can actually cause leaks, and lead to the development of mold and mildew, which could result in health issue and respiratory problems for people living in the house.
Icicles are also the result of bad insulation and ventilation. They tend to happen when snow accumulating on a roof melts and runs off, only to freeze hanging down when it hits the cold roof’s edge. Icicles are in reality very dangerous; they are heavy on the roof and gutters, and if they fall, they could cause serious injuries.
Leaky flashings, or weatherproofing, are very common during winter, especially for houses with sloped roofs. Flashings are metal strips that are placed on the front edge, corners, ridges, in addition to around chimney and skylight. Those metal strips can peel away from a roof during a storm, and cause water to leak inside the house.
Faulty ventilation can cause water to get trapped inside the roof. Trapped water can be absorbed by roofing materials, causing problems such as cracks in the roof. Due to the cold outdoor weather and warm indoor air, said water can freeze and thaw multiple times, each time inflicting more damage to the roof.
