If you have contacted a Minneapolis roofing service to build a wood-shingle roof for you, then you should know some facts related to weathering suffered by wood roofs. More roofing details.
• Wood reacts to both rain and sunlight – both affect its surface. The occurred changes are physical and chemical as well, and together they go under the name of “weathering”.
• Color change – this is usually the first to occur. The original brownish color fades away in time and a graying process starts to develop. This effect is caused by UV light and can be noticed from the first year. The silver gray darkens with time, which means that fungi have grown on the wood.
• As a result of contact with water, wood swells. When drying off, the wood then shrinks. Constantly going through swelling and shrinking, the wood develops cracks in it. With time, the originally microscopic cracks grow larger. Freezing and thawing also contribute to the process.
• When larger cracks trap water in them, organisms that cause wood to rotten can develop there.
• Due to wind and dust, edges are no longer sharp with aging and the surface of the shingles changes too.
• Debris falling from trees can accumulate between the wooden shingles.
Wood roofs have a lifespan of up to 15 or 20 years, but they require maintenance. Minneapolis roofing services can deal with inspecting the roof each year and performing necessary maintenance services.
