Roofing in Harwood Heights, IL

Serving Harwood Heights and Surrounding Areas

Harwood Heights roofs face specific problems because of the local climate and construction style. Here’s what we see most often:

**Ice dams** – When snow melts and refreezes at the eaves, water wicks up under the shingles. This causes rot in the decking and leaks inside the walls. We fix this by adding ice-and-water shield and improving attic ventilation.

**Hail damage** – Spring storms often drop hail that fractures asphalt shingles. Granule loss accelerates, and the mat oxidizes. We inspect for blistering, cracking, and splits. A full replacement is usually needed if more than 20% of the roof is compromised.

**Flashing failures** – The original step flashing on 1950s ranches often corrodes or delaminates. Water seeps behind the siding and rots the sheathing. We replace it with new aluminum flashing and hand-seal every joint.

**Sagging rooflines** – Older homes with low-slope roofs can settle over time. The decking bows, and the membrane punctures. We reinforce the structure with new plywood and reset the roof deck before installing new material.

**Wind uplift** – On steep roofs, strong gusts can lift shingles and tear them off. We use ring-shank nails and a 6-nail pattern per shingle to keep everything locked down.

**Moss and algae** – Shaded areas near trees trap moisture. Moss holds water against the shingles, causing decay. We clean the roof and install zinc strips to prevent regrowth.

**End-of-life wear** – Many Harwood Heights homes still have the original roof from the 1980s. The shingles curl, the granules erode, and the felt deteriorates. A full tear-off and replacement is the only solution.

If you see any of these issues, call us. We’ll diagnose the problem and give you a plan to fix it.
