A sturdy roof protects your home or business from the elements. It has to withstand strong winds, heavy downpours, snow and ice accumulation. Whether it’s a repair or installation, your roof needs to be properly maintained to protect your investment. Residential and commercial roofs can suffer from multiple roofing problems.
Does Your Roof Need Repair or Replacement?
Water leaks can damage the roof decking. Further problems indicating a repair or re-roofing may be necessary which could include one or more of the following:
The failure to fix minor problems
Water pooling on the roof
Failure of roof perimeters e.g., gravel stops
Poor design choices
Weathering and wind damage
Lack of roof maintenance
Shingles that show granule loss, are missing, or have curls and/or cracks
Flashing and drain problem
Roof maintenance is often forgotten or ignored until a leak appears or the owner's insurance company recommends action. Some homeowners believe that to shingle a roof, all you need to do is buy some shingles and nail them on the roof. A great deal has changed in the shingling industry. Old shingles have to be removed (and disposed of), any rotten roof sheathing replaced, and ice and water shield, felt and flashing installed. At the same time, the peaks and valleys need to be completed and proper ventilation techniques applied.
The biggest cause of premature roof failure is the inability to locate and correct minor problems; the lower the roof slope, the greater the impact. Insufficient ventilation can markedly decrease the life of the roof. Also, ventilation will not solve the problem of water leaking into the attic.
These shingles show the effects of weathering and sun damage. A new roof prevents water damage and adds value to your home. Finding tiny granules in your eavestrough? These granules provide weatherproofing and protection from ultraviolet rays. Missing shingles are also a sign of roof trouble. Curling and cracking shingles signal a loss of wateeer resistance.
This slope to flat roof transition will fail prematurely due to expansion and contraction of the material at the change in deck direction, causing membrane splits. In addition, incompatible roof materials, poor drainage, sagging structure and roof-on-roof designs can all contribute to premature roof failure.
The type of roofing material dictates the life of the product you have; the less organic the material, the longer the life. Damage to roofs can be caused by hail, air pollution and a salt-laden atmosphere. The greatest factor in prolonging a roof's life is adequate fastening of the roofing material to the deck and at the perimeter. High winds tend to loosen the roofing materials and no roof can withstand extreme winds and flying debris.
Out of sight, out of mind: Often the first indicator of a roof issue is water damage. This is particularly true for flat roofs, where it is easy to forget to check drains, to clean off plant residue and garbage from roof when it is not easily seen.
Water collecting on roof can magnify UV rays and decrease the life of the roof, particularly for BUR and bituminous roofs. Root-top units without proper drainage can compound the problem.
Flashing & Drain Problems
The function of flashing is to provide a watertight connection between the roof and projections. Many early roof leaks are the result of flashing problems and prompt repair will extend the roof's life. The drains provide for the removal of water as quickly as possible and should be inspected for blockages frequently.
