The life of a roof which battles the elements day to day and year to year, keeps you warm and dry in the winter and cool in the summer needs a little of your attention each year.
Here’s a factor for every roof, no matter where it is. The sun’s baking rays slowly degrade roofing materials, while wind, rain and hail sometimes cause immediate injury. Snowy climates offer special challenges, from the sheer weight of snow buildup to ice dams that break gutters and foster leaks. The more extreme conditions are in an area, generally or in any given year, the more need for constant vigilance to spot small problems that could easily become large ones later on.
If the temperature in an attic is not close enough to the temperature outside, condensation can occur, promoting rot of the sheathing underneath shingles and of rafters. Proper attic ventilation often solves the problem.
Moss and Algae
In many regions, too much shade and too little sun promote the growth of moss and staining algae. Left alone, moss creates a perfect environment for moisture buildup under shingles, according to roofing specialists, and trapped moisture increases the chance of wood rot. Meanwhile, algae’s dark stains can affect a roof’s reflective.
A much-loved source of shade and beauty in most contexts, trees over a roof can be problematic — dumping leaves in gutters, dropping heavy branches and, if not properly trimmed, scratching away at a roof’s surface. Trees also offer little critters a way up and onto a home. Once they’re up, an attic looks awfully inviting.
Overhead shouldn’t mean out of sight and out of mind. Regular inspections and quick attention to problems will help any roof live a long and useful life.
