Minnesota roof damage and common Minnesota roof problems are detailed below.
Weathering
Weathering is known as nature’s effect on shingles and weather enhanced deterioration of roofing system components. This includes the expanding and contracting of shingles, irregular loss of shingle granules, and negative effects on a roof’s water shedding ability. With simple maintenance and routine inspections these symptoms can be detected early and prevented from advanced stages. In Minnesota, the need for regular inspections and routine maintenance is magnified due to common seasonal storms, heavy snow loads, extreme temperature and the tendencies of vast temperature swings.
Lack of maintenance
General roof maintenance items include clearing debris from roof valleys and drainage points, checking the integrity of chimneys systems, ensuring silicone adhesion around pipes and flashing, inspecting for curling or clawing of shingles, and ensuring proper attic ventilation. Though roofs are high and often steep, they require basic maintenance much like a lawnmower or furnace. Not every trip up on the roof will reveal any of the prior mentioned problems or others not noted, but roofs should be inspected yearly regardless. If left unattended, problems can snowball into major issues very quickly. CAUTION: Inspecting a roofing system is very dangerous. Contact us for a no obligation roof inspection.
Hail damage
With the regularity of strong thunderstorm s and hail storms in Minnesota, we commonly find storm related damage on many home’s roofing systems. Hail damage reduces the water shedding ability of roofing systems and shortens the life expectancy of shingles. Other storm related damage includes flying debris and the dragging and rubbing effects of windblown tree limbs and branches. Undetected, hail damage and storm damage can cause major water damage and quickly become a major roof problem.
Poor ventilation
Poor attic ventilation is detrimental to the life expectancy and function of roofing systems. Essentially, the temperature of attic spaces should be very close to that of the outside air temperature. This prevents common problems like ice dams, shingle curling, and shingle clawing. If the attic is overly warm or hot in the winter, ice and snow melts too quickly and then re-freezes at the roofs eve. This causes ice damming. Ice and snow should melt at a natural rate. If the attic is overly hot in the summer, it can virtually bake the shingles like cookies on a baking sheet causing curling and clawing. Proper attic ventilation prevents these problems and allows for proper air flow and essential circulation.
Improper shingle installation
Poor shingle instillation is a common roof problem in Minnesota. Some of these commonalities include nails installed improperly on the shingle sealing strip, rubbing and marring from repeated foot traffic, scrapes and scratches from tool dragging, and cuts and scoring from cutting shingles on top of installed shingles.
