Modern technology allows roofing manufacturers to do amazing things today, but Mother Nature has the last word when it comes to the appearance and performance of your roof.
For example: Ultraviolet sunrays can cause shingle deterioration, temperature extremes can damage shingles because of expansion and contraction, shingles can blow off from strong wind gusts, damage to the attic can occur from wind-driven, horizontal rain, and the accumulated stress of rain or snow buildup is sometimes just too much for your roof.
Half of the battle with Mother Nature is won using quality materials and competent contractors to install them. If you're not sure whether you need a new roof, review the following key danger signals that your roofing system is not protecting your home:
- Leakage in the attic after a driving rain. Possible causes: Leaky or inadequate shingle under aliment or deteriorated flashing.
- Blistering and/or peeling of inside or outside paint. Possible causes: Excessive moisture or high humidity due to poor attic ventilation.
- Stains on interior ceilings and walls. Possible cause: Inadequate or faulty shingle under aliment allowing leakage from ice dams.
- Roof shingle, sheathing or siding decay. Possible cause: Poor attic ventilation.
- Missing, cracked or curling shingles. Possible cause: Shingles have reached the end of their useful life.
- Dark, "dirty-looking" areas on your roof. Possible causes: Environmental pollutants; vegetation, fungus or algae growth; loss of granules due to age of shingles.
- Excessive energy costs. Possible cause: Insufficient attic ventilation causes heating/cooling system to run excessively.
