How to identify cracking and blistering in asphalt shingles?
Look for visible cracks or raised, bubble-like blisters on the surface of the shingles. These can sometimes appear as isolated spots or widespread areas of damage.
Why is cracking and blistering of asphalt shingles a problem now?
Cracks and blisters weaken the shingles’ structural integrity, making them more susceptible to water infiltration and further damage from wind or debris.
Why/how this problem will get worse (cracking and blistering)?
Left untreated, cracks can expand, and blisters can burst, leading to leaks and accelerated roof degradation, especially under extreme weather conditions.
How to identify Granule loss with asphalt shingles?
Check your gutters and downspouts for an accumulation of granules or inspect shingles for bald spots where granules have worn away.
Why Granule Loss is a problem now?
Granules protect shingles from UV rays and weather elements. Loss of granules exposes the asphalt layer, reducing the roof’s ability to repel water and resist heat.
Why/how granule loss gets worse?
As UV exposure increases, the asphalt layer becomes brittle, accelerating aging and leading to cracking or curling, which could result in leaks.
How to identify curling and buckling in asphalt shingles?
Shingles appear to be lifting or curling at the edges, or you may notice ridges and waves across the roof surface.
Why curling and buckling is a problem now?
Curled or buckled shingles can’t properly seal, leaving gaps for water and wind to enter. They also make the roof more vulnerable to wind damage.
Why/how curling and buckling get worse?
Over time, moisture penetration will cause the decking beneath to rot, and the shingles may break off entirely in strong winds, leading to more extensive repairs.
How to identify leaks and water damage?
Check for water stains on ceilings or walls, sagging roof sections, or visible wet spots in the attic after rain.
Why are leaks and water damage a problem now?
Water infiltration can damage the roof structure, insulation, and interior surfaces, leading to costly repairs.
Why/how leaks and water damage problem will get worse?
Persistent leaks cause rot and mold growth, compromising the roof’s structural integrity and creating health hazards inside the home.
How to identify Algae and moss growth?
Look for green moss or black streaks on the roof, particularly on shaded sections with poor drainage.
Why is algae and moss growth a problem now?
Moss holds moisture against the shingles, accelerating wear, while algae can discolor the roof and reduce its curb appeal.
Why/How is algae and moss growth will make this problem worse?
Over time, moss can lift shingles, allowing water to penetrate, and alga can weaken the shingles protective layers, leading to premature failure.
How to identify wind damage?
Check for missing or lifted shingles, especially after a storm. Pay attention to areas near edges, ridges, or flashing.
Why is wind damage a problem now?
Missing or loose shingles leave the roof exposed to rain and debris, increasing the risk of leaks and structural damage.
Why/how will wind damage cause problems to get worse?
Continued exposure can lead to widespread shingle loss, making the entire roof vulnerable to failure in future storms.
How to identify Ice Dams?
Look for icicles handing from the roof edge or water strains near the walls or ceiling in winter months.
Why are ice dams a problem now?
Ice dams prevent proper drainage, causing water to back up under shingles, leading to leaks and potential rot.
Why/how ice dams cause problems to get worse?
Repeated freeze-thaw cycles exacerbate the issue, causing extensive water damage and reducing the lifespan of both the roof and supporting structure.
How to identify poor installation?
Uneven shingle alignment, exposed nails, or inadequate flashing are signs of poor installation. Leaks and early signs of wear often appear prematurely.
Why is poor installation a problem now?
Improper installation comprises the roof’s ability to withstand weather and perform its intended function, leading to reduced efficiency and lifespan.
Why/how poor install causes problems to get worse?
Over time, issues caused by poor install - like water infiltration or inadequate ventilation - can lead to costly repairs or even a full roof replacement.
