The average lifespan for an 3-tab asphalt shingle roof is 15-20 years. Roofing materials age differently and weather and geographical location plays a major factor as to how the how the expiration of shingle roofs can vary.
Shingles that are buckling in the middle, curling at the edges or missing altogether can be a sign of weakening as they age and may result in leaks or water damage if not addressed. Asphalt shingles are covered in granules and some shedding is normal after the first year or two after installation. If you have an older roof and are finding excessive sand-like material in your gutters, it is a good indicator your roof is shedding layers which will cause the shingles to become brittle and crack, which may also result in further damage or leaks. It's important to determine whether you have minor shingle damage that can be repaired or extensive shingle damage that should be replaced - we are here to help you every step of the way!
Structural inconsistencies should never be ignored. If there is any indication that your roofline appears to "dip" or look uneven, you should contact us immediately to avoid any type of structural collapse. Bowing, drooping or dipping indicates the support boards underneath may be weakened by rot or moisture and must be addressed as soon as possible. If moisture is reaching the support, it is likely the roof needs to be replaced.
Consider several possibilities of moisture damage - water leaks, stains, sounds, smells, light. Moisture may or may not be evident and come in many different forms: visible leaks and stains in ceilings, walls, chimneys, attics or several other places throughout your home; you may hear dripping noises but not be able to see any indication of water; moldy or musty smells are signs of trapped moisture that could be an underlying issue that can become dangerous quickly; sunlight shining through gaps or holes where it shouldn't be. A lot of these issues are caused by the general deterioration of a roof over its lifespan, damaged flashing or poor initial installation. Sometimes repairs can be made but it's important to determine if the roof may be past the point where repairs are no longer cost-effective and if a replacement is the best option.
