How To Tell Your Roof Needs Resealing

Posted on: 27 January 2023

A roof will offer a reliable lifespan if you service it regularly. As such, you must seal the roof to guard against deterioration by weather elements. However, your roof may sustain age-related deterioration, which makes the seal coat wear off and disintegrates the roof's components. Moreover, if neglected, your roof may develop leaks that can cause water damage. Thus, you should contact a roofer to assess your roof and determine whether it needs resealing. Below are the signs to watch out for. 


If you notice signs of corrosion on your roof through a visual inspection, you should reseal it. In most cases, this occurs due to the seal coat wearing off, exposing the base metal to weather elements. Further, corrosive rain and salty ocean water can accelerate rusting, weakening metallic components. In addition, improperly laid shingles can alter the roof's drainage, creating ponding water that promotes rust. Therefore, you must engage a roof repair expert to reseal your roof for protection against the elements.

Damaged Components

Besides falling objects and foot traffic, worn-out sealant can cause damage to your roof. In most cases, the seal coat may deteriorate from constant UV ray exposure, compromising your roof's structural integrity. Further, this can cause the protective granules in the shingles to weaken and disintegrate. Ultimately, you will end up with curled shingles, cracked flashing, and broken tiles. Note that since damaged roof components allow leaks, you should hire a roof repair expert to replace the damaged components and apply a seal coat to restore your roof.

Water Staining

If you notice water stains on the ceiling and walls, your roof could be leaking. In most cases, this happens due to mechanical abrasion from airborne pollutants that thin the seal coat. In other cases, the roof membrane may detach from the underlayment, creating spaces for leaks. When this happens, you will notice water stains on the ceiling and wall discoloration. Thus, you should employ roofing services to reseal your roof and prevent leaks.

Mold and Mildew

Faded spots on your roof's surface indicate the seal coat's deterioration. As such, the roofing material will break down, leading to dips. Additionally, moisture can penetrate through the shingles and become trapped. This enables mold and mildew to grow, which can cause damage to the wooden components. Therefore, you must ensure a proper seal coat to prevent mold growth.

You should know that sealing your roof protects it from harsh elements, increasing its longevity. Thus, you should schedule roof restoration with a roofing contractor for quality seal coating.
