Even a roof with sound construction and no leaks has a finite lifespan. Once an asphalt shingle roof passes the 20 year mark, you should be vigilant for signs of wear. Watch out for failing shingles so that you can consult roofers in Winnetka Il prior to the development of leaks.
1. Shingle Granules in Gutters
The presence of excessive granules in gutters means that the shingles are breaking down. This early warning sign should put you on alert that the elements have begun to undermine the integrity of the shingles.
2. Curling or Cracked Shingles
Visible inconsistencies in the roof surface indicate that the shingles are lifting away. Curled edges and cracks allow moisture to creep under the shingles. If this damage is only occurring in a limited area, roofers in Winnetka Il might make repairs and prevent leaks. A professional could also figure out what might be causing the deterioration. Wet climates, low roof slopes, and accumulations of tree leaves or pine needles could hasten the aging process.
3. Moss is Growing
The growth of moss generally follows when debris gets caught in the edges of curling shingles. The debris retains moisture and creates a welcoming environment for moss.
4. Missing Shingles
Shingles that have slid away or blown off cannot be ignored. This is the first step toward the total compromise of roofing materials.
5. Peeling Chimney or Vent Flashing
Because these parts represent holes in your roof, any problems with the flashing invites water inside the building. Flashing done with roof cement or tar is prone to failing. Replacement with a water-tight metal flashing will provide long-term protection.
