Roofs may endure 20 to 50 years, and longevity requires upkeep. You can't be hands-off with your roof, and there are times when you should do a roof call.

1. Your Roof Has Granule Loss and Shingles

Shingles don't only look good; they also assist the remainder of the roof safe from harm by creating a watertight and windproof seal.

Roof shingles have failed if you observe a slight accumulation of black or gray dust or granules in your gutter system or your downspouts. If you see a few shingles missing, or if a shingle has come away and landed on your yard, you should do the same thing.

2. The Shingles on Your Roof Pop

Impact damage from hail or poor attic ventilation may also cause sagging shingles that seem to rise above the rest of the roof's flat surface.

Shingles might blister or burst if the temperature in the attic rises beyond 120 degrees Fahrenheit. A skilled professional will also examine attic ventilation and the source of shingle damage via roof call.

3. Your Roof Has Water Stains and Leaks

Do a roof call if you see noticeable water stains and leaks on the roof and everywhere the roof spills onto (like in your attic). If you see water stains on your ceiling or walls, you may have a leaking roof, which may cause significant damage. You should also look for strange water pools during and after a storm.

4. You See Loose or Worn Flashing

Cracked, loose, or worn flashing surrounding your vent stack and chimney is often a sign of a bigger problem and should be addressed. When shingles contact a protrusion, they are more likely to break off. Roof leaks may be caused by caulking or flashing that has been put incorrectly or failed.

5. Unusual Post-Storm Debris on Your Roof

Storms, blizzards, and other inclement weather may do a lot of damage to your roof. When a storm comes through, it's usual for shingles to blow off the roof, tree branches to fall, and other things to end up all around.

Check your roof thoroughly after a storm and watch for damage and debris. Do a roof call if you see anything out of the ordinary. It's usually simpler to fix a minor issue before it grows into a major one.

6. Algae, Mold, and Moss Are Growing on Your Roof

Depending on the outbreak's severity, you may need a complete roof replacement if you see algae, mold, or moss growing on your roof. After the wind carries spores to your roof, algae, and mold develop in the crevices and corners. Algae and mold may produce stains and leaks if left uncontrolled.

7. You Can Spot Ice Dams

When the temperature in your attic is high enough to melt the snow, ice dams develop, allowing water to infiltrate behind the shingles and cause damage. These ice dams may break your gutters off, damage your roofing, and create enormous leaks if you don't have them taken care of.

8. Sagging of Your Roof

Damage to the structure is probable if you see any drooping in your roof. It would help if you looked for dips in the roof's plane or bowed rooflines. If you find your roof drooping, do a roof call right away. This indicates that the damage has penetrated the decking underneath the roof's surface.
