Common Problems Roof Cleaning Prevents
Most people today probably do not spend much time thinking about the cleanliness of their house roof. Believing if it is not leaking then there is no problem, right? That is wrong. There are some roof cleaning issues that if left unchecked, which can wreak havoc on shakes, shingles, and tiles, eventually leading to declining of the roof structure itself. This piece will discuss some of the causes, signs of trouble, and some of the cleaning methods used to eliminate potential problems. Preventative measures are always less expensive than replacement costs or repairs. That is why we advise you to hire a professional roof cleaning contractor. Below are some of the problems roof cleaning help to prevent.
- Roof Cleaning Prevents Black Algae
Informally called as or ‘fungus’ or ‘mildew,’ black algae is usually found on an area shaded by a tree or on the shadier slope of the roof. The staining tends to be uniform, unlike the black streaking saw when asphalt shingles bleed-through. The black stain is dead organic debris from dead algae. There are shingles made with copper granules or zinc designed to restrain algal growth. Another way to help evade black algae is to trim tree branches protruding from the affected area, allowing more sunlight. Some copper strips fixed to the ridge can also bring about algae, which kills metal salts to wash down the roof when it rains. Some people use pressure machines to wash the algae, but I feel this is detrimental to shingle integrity. There are plenty of chemical solvents to remedy this problem. The best decision is to contact a professional roofing contractor to help make the right choice, for both you and your roof type.
- Roof Cleaning Prevents Debris Staining
It is a common problem, particularly on low-pitched roofs with overhanging branches. Staining happens when piles of debris, such as leaves or needles from coniferous trees collect on the roof. These piles retain water and can cause severe damage if not dealt with. Apart from fungi and algae, plants can also grow here if proper measures are not implemented. I have seen roofs with 6+ feet plants growing on them, complete with elaborate (and destructive) root systems growing into the roof structure. Lichens, moss, and other plant life can often thrive on a neglected roof. The primary way to combat this particular type of problem is to physically remove debris from the roof by washing and sweeping plant matter from the ceiling. Care should be employed not to damage the shingles or other roofing material. Debris staining is a prime sample of how repairs are far more expensive than prevention. It is easier to eliminate debris from a roof than to fix the resultant damage if not removed.
- Roof Cleaning Prevents Black Streaking
When black stains befall on your roof in the form of streaks, it is most likely a case of ‘bleed through.’ That occurs when the bituminous material in asphalt shingles starts to break down and bleed from the shingle. Regrettably, this is usually a sign of faulty materials or older shingles in need of replacement. It can be hard to differentiate bleed-through from black algae, which is why I always recommend soliciting the advice of a trusted roofing contractor before making any decisions on a course of action.
