Roof Valley Cleaning

Roof valleys carry more water than any other part of your roof. SQ Roofing Inc. (Supreme Quality Roofing Inc.) clears the leaves and debris that build up there before they cause leaks.

What Roof Valleys Do

Where Two Slopes Meet, Debris Collects

A roof valley is the channel formed where two roof slopes meet. Because water from both slopes funnels into it, a valley carries a large share of the rain that hits your roof.

That same shape traps leaves, pine needles, and dirt. Once debris builds up, it acts like a dam: water backs up, spreads sideways under shingles or tiles, and finds its way to the underlayment and decking. Wet debris also feeds algae and moss, and on tile roofs it can hide cracked or slipped tiles.

SQ Roofing Inc. (Supreme Quality Roofing Inc.) clears valleys by hand, flushes out fine sediment, and inspects the valley metal and surrounding roofing so water can run freely again.
