Davis Roofing: Article About Time For A New Roof
It's easy to put off repairing a roof when the weather isn't too bad or there are more pressing matters to attend to, but eventually, the water dripping into the attic and through the ceiling will become a nuisance. There are many ways to tell if a roof needs to be repaired or completely replaced, although according to the National Roofing Contractors Association, most roofs under 20 years old can be successfully repaired rather than replaced. The surest way to tell whether a roof needs repairs is to climb up to the roof on a ladder or look through a second-story window at the condition of the existing shingles. If they're worn or seem patchy and dark in uneven patterns, it's most likely time to call a Davis roofing contractor to take a professional look at the roof.
Depending on the type of material the roof is made from, there are different ways to estimate the roof's existing condition. Shingles made from wood or fiberglass typically last 20 years before needing to be replaced, and the underlying structure can last a longer time if it was installed properly. Composition shingles made from wood or asphalt often shed the small granules that give them grit, depositing them into the storm gutter, so if there is an unusual amount of gritty silt in the gutters, it's a possible sign that the shingles have worn down considerably.

In dry climates, shingle roofs tend to crack as they age, while in humid climates, they begin to sprout moss. This dark green plant matter erodes the shingles and makes them fall apart when the rain pours down on them, and it can become a structural issue if it spreads throughout the entire roof.
While most homes have shingle roofs with moderately steep slopes, many houses have tile roofs with low slopes. Tile roofs typically last up to 100 years with proper maintenance, and when the tiles on these roofs break, they must be replaced by a professional. It's a good idea to walk on a tile roof as little as possible to prevent breakage, especially on a roof that's in need of repair. A broken roof tile can slip out from under a person's foot while that person is walking on the roof, so homeowners should never attempt to repair roof tiles themselves without professional training. Commercial buildings with flat, asphalt roofs never need a complete replacement, although they often require maintenance to prevent cracks and to keep the reflective gravel evenly distributed.
