Signs Shingles Roof Replacement Is Necessary

Shingles roof replacement can be the way to go to fix your damaged roof instead of doing the repairs. While repairs are usually more affordable than replacement, it sometimes makes a lot of sense to just do the replacement and do away with the old shingles. But how do you know that what is needed is shingles roof replacement?

In this post, we have shared some of the surest signs that you should contact a roofer for shingles roof replacement.

Buckling shingles

A buckling shingle is a visible waved distortion which normally runs vertically up the slope of a roof. Buckled shingles are usually highly susceptible to ice and wind damage, and can easily be torn off. Poorly installed underlayment or overall roof age and wet are usually the most common causes of buckling shingles.   

Clawing or curling shingles

Clawing or curling shingles are a sure sign of excessive heat. They are also a clear indication of an aging roof system. Clawing or curled shingles are known to be very susceptible to ice damage and wind uplift. Shingles will usually become rigid overtime and can easily break and lose tab edges.

Missing or broken shingles

Missing and broken shingles can weaken the entire system of a roof and compromise its ability to shed water. They can also be the entry point of water. Physical damage and excessive wind are two of the major causes of damaged shingles.

Missing bar spots or granules

Poorly designed valley drainage, lack of eaves trough, or poorly placed downspouts on a second storey can potentially cause a waterfall effect which washes away shingles over time. Physical damage or aging of a roof system can also cause bare spots as well as a loss of granules. The loss of the protective granules of the shingles makes the shingles to start to harden from sun and heat exposure. Granule loss on the system of a roof can accelerate shingle decay and aging and can even become an entry point for water.

Damaged flashings

Flashings located around chimneys, rakes, stacks, wall details, eaves, valleys, and skylights are all subject to lifting, separation, and dried out caulking. When any of these happen, the flashing details can start lifting and eventually separate because of the general contraction and expansion. Expansion and contraction can affect fasteners and make them become loose thereby causing the bottom-flashing flange to start lifting. This will allow water to enter.
