Here are some of the warning signs that your roof needs repair or replacement:

    1. You can see damage, Algae or moss, mildew, missing shingles or flashings, or other damage. Your best protection against further damage or damage to your house from water penetration is to call Tri State Roofing for an assessment. You may not need a new roof, just a repair.
    2. Algae growth. Causes a dark discoloration. The algae are usually brown to black in color which results in streaking and a dirty looking roof it creates a black-green stain. Algae can retain moisture causing rot and deterioration. It can be mistaken for soot, dirt, or tree droppings. It’s caused by the growth of air-borne algae which deposits on the roof. Other causes for Algae are trees and bushes, damp shaded areas and gutters that aren’t cleaned on a regular basis to maintain good drainage.
    3. Moss growth. Moss can grow out of control and cause severe problems if not addressed. Once moss grows, moss holds even more moisture to a roofs system surface which causes rot. In addition moss roots also work their way into a wood deck and structure.
    4. Buckling. Improperly applied felt, wrinkled underlayment, roof deck movement, spacers not being used in between roof deck boards, poor ventilation or new shingles being applied over old, rough shingles.
    5. Curling. High nails, lack of back coating, Under saturation of asphalt felt in shingles, lack of ventilation, Improper number of fasteners.
    6. Blistering Damage. Moisture in the shingles. Most likely to occur when there is inadequate ventilation.
    7. Damaged Flashings. Many apparent roof leaks are really flashing leaks. Improper installation and denting by improper nailing or non installation of correct flashing can cause major concerns. Without good tight flashings around chimneys, vents, skylights and wall/roof junctions, water can enter a home or building and cause major damage to walls, ceilings, insulation and electrical systems. Flashings should be checked as part of an annual roof inspection and gutter cleaning.
    8. Missing or torn shingles. Improper fastening, exposure to high winds. When shingles are old and worn out, they curl, split and lose their waterproofing effectiveness. These shingles are easily blown off, torn, and lifted by wind gusts. The end result is structural rot and interior damage. The problem is likely to spread to nearby shingles. It will only get worse with time and should be replaced as soon as possible.
    9. Tree and leave damage. Tree branches touching a roof will scratch and gouge roofing material. Falling branches from overhanging trees can damage, or even puncture shingles and other roofing material. Leaves on a roof system’s surface retain moisture and cause rot, and leaves in gutters block drainage.
    10. Excessive sediment in your gutters. This could be an indication that your composite roof is decaying and may need replacement.
    11. Sun Damage. Heat and ultraviolet rays cause roofing materials to deteriorate over time. Deterioration can occur faster on the sides facing west or south.
    12. Water Damage. When water gets underneath shingles, or shakes or other roofing material. It can work its way to the roof deck and cause the roof structure to rot. Extra moisture encourages mildew and rot elsewhere in a house, including walls, ceilings, insulation and electrical systems.
    13. Ceiling Spots. Caused by leaks in the roof.
    14. Rotting. Rotting is caused by the absorption of moisture by the mat at the core of the shingle.
    15. Condensation. Condensation problems result from the build up of relatively warm, moisture-laden air. Moisture in a poorly ventilated attic promotes decay of wood sheathing and rafters, possibly destroying a roof structure. Sufficient attic ventilation can be achieved by installing larger or additional vents because the attic air temperature will be closer to the outside air.
    16. The age of your roof makes you concerned about its condition. Roofs approaching 15 years old, depending on the materials used (i.e. cedar shakes), may be reaching the end of their life. Learn the condition of your roof, so you can plan ahead and avoid problems.
