Do You Have Roof Debris Damage?

ROOF DEBRIS – Black & Brown Debris Stains on Asphalt Shingle Roofs

Debris staining on roofs produces fairly uniform black or brown staining in areas where due to low-slope or presence of overhanging trees, leaves, or organic debris collects on the roof slope.

Decaying debris may encourage fungal or algal growth

Lichens or even thick moss may also grow on such roof areas. Debris, lichens, or moss on a roof will shorten its life by holding water on the roof surface, preventing drying, and (in cold climates) adding wear and tear on the roof surface by freeze-thaw cycling.

In contrast, debris from an upper roof gutter that spills onto lower roof slopes may result in tan, white, or other stains depending on the metal of the gutter and the length of time that leaves and debris rest in it. (Photo at left).

The decision to permit the upper roof gutter to spill down the lower slope also risks creating an early wear-area and thus leaks on the lower slope roof.

Remedies for black or brown or gray debris staining on asphalt shingles: As cited above, cleaning off debris (gentle sweeping or washing, watch out for damaging the roof during cleaning), or cutting unnecessary overhanging tree branches may help.

What is a Roof Rafter?

Rafters support the roof sheathing and transmit the roof loads to bearing walls or beams below. The term “rafter” is associated with sloped roofs. When these members are found on a flat roof, they are called “roof joists”, although they do exactly the same job.

Rafters can usually be seen overhead, when standing in the attic. Some rafters support finished ceilings, for example, where there is a cathedral ceiling. In this case, roof insulation is often fit between the rafters.
