Best roofers near Jackson, MN

You can only overlay a roof once. Any additional layers of shingles will add too much weight and may also violate building codes. Once your roof has had an overlay, you’ll need to have a full roof replacement, including a tear-off of all existing roofing materials, when it’s time for a new roof. 

Hail is unlikely to damage a tar and gravel roof because the hailstones will hit the protective gravel rather than your delicate roof membrane. A tar and gravel roof is the most resilient flat roof option, which means it’s the best one for areas that see hail, fallen tree debris, and blown debris from intense winds.

No, ice dams aren’t a standalone sign that you need a new roof. Ice dams can form on new roofs, as issues with the insulation inside your home are often the underlying problem. However, if you notice signs of roof damage from ice dams, you might need to hire a local roofer for repair or partial replacement.

The lifespan of a torch down roof depends on the number of layers installed. A single-ply system typically lasts between 10 and 15 years, while a multi-layer system with two or three layers can last from 15 to 25 years. Although a multi-layer option may be more expensive upfront, it provides a longer service life. Warranties often reflect this, with about 12 years for a one-ply system and 15 years for a two-ply system. For context, this lifespan is shorter than other common roofing materials like wood or asphalt shingles, which typically last 20 to 30 years, with high-quality versions lasting up to 50 years.
