What are common problems with roof shingles?

While metal roofs have skyrocketed in popularity in the last few years due to their hardy reputation and crisp aesthetic, asphalt shingles are still a popular and frequently installed roofing material. Considered the standard roofing material, the manufacturing of shingles has advanced to the point of innovative improvements in the longevity and appearance of asphalt shingles. Today there is less cracking, tearing, and moisture susceptibility, pushing the estimated lifetime of asphalt roofs to potentially twenty or more years.

Shingles don’t Last as Long as other Roofing Materials

The unstoppable wind and water pressure produced by tropical storms and hurricanes can get the best of any roof regardless of material. However, proper materials and installation techniques can go a long way towards protecting property from weather-related damage.

While skilled roofers are always in demand, years of experience becomes even more critical when considering installing or replacing shingle roofs. Nail placement will directly impact the appearance, durability, and longevity of the finished roof. If nails are not placed a specific distance apart, the roof is not compliant with building codes and may be more susceptible to rot.

Materials and Installation Methods Matter More

In South Florida, special thermal-diffused galvanized ring shank coil nails are required by law for increased durability. Nails should be installed in a staggered pattern to keep the roof edging flush to prevent the wind from picking up the corner. Tin caps or fasteners must be consistently spaced, close together, to secure the barrier paper between shingles and plywood, preventing exposed plywood in the event of adverse weather events.

The underlayment paper installation method is another critical element affecting the long-term success of a shingle roof. If shingles are torn off in severe weather, properly installed underlayment is vital—thickness and quality of paper matter for the long-term integrity of the roof installation. Miami roofs will not pass inspection if the paper is not secured correctly and overlapped to prevent the seams from weakening or collecting water over time. 

Roof Shingles have Cost Advantages

Shingles are easy to handle and can be shipped and installed without fear of material loss, unlike Spanish clay tiles, which require handling with care and regular maintenance if and when chipping or breakage occurs. Roof shingles are lower cost upfront, making them more cost-effective, and may be repaired or replaced in increments over the long term, unlike metal roofs which would lose whole sections or sheets at a time. 

Thicker, dimensional shingles are more resistant to wind damage than traditional thin shingles and have fewer problems with curling over time. According to Big Al’s Roofing, curled shingles are as bad as cracked shingles, and neither will provide adequate protection against water damage. If granules are starting to shed into a gutter, it may mean roof shingles could be wearing down, and reroofing may be needed shortly.

In roof repair or replacement, it is also essential to thoroughly de-nail the existing roof. If not de-nailed, old nails that have been covered over may work their way into the new shingles and damage the integrity of the new roof.
