Local know-how
What we see on Thornton roofs
Thornton has grown steadily north of the city. The older neighborhoods toward the south end date from the 1950s and 1960s and have simpler roofs that are on their third or fourth covering. Much of the rest was built in the last few decades, with larger, more complex roofs and builder-grade shingles that are now wearing out.
The open plains around Thornton leave many homes exposed to wind. Gusts lift shingle edges and break their seal, and roofs that face open fields or wide streets tend to lose shingles first. If you find shingle pieces in the yard after a windy night, have the roof checked before the next storm tears off more.
Gutters on many newer homes here were sized on the small side, and they overflow in summer cloudbursts or fill with ice in winter. Larger continuous gutters, more downspouts and extensions that carry water away from the foundation usually solve it. Hail also dents gutters, so check them after every storm.

5 out of 5 stars
Our gutters overflowed every summer storm. They put in larger one-piece gutters with an extra downspout and extensions away from the foundation. The basement has stayed dry since.

We got ice dams every winter on the north side. Instead of just selling us heat cable, they fixed the attic ventilation and added insulation. No ice dams this year.

Wind took a section of shingles off at night and rain was coming in. They had a tarp on the next morning once the wind dropped and fixed it properly two days later. Wish it had been sooner, but they explained why.
