Advantages Of Installing A Steel Shingle Roof Over The Existing Asphalt Shingle Roof
In order to maintain longevity of your roof, you can arrange a steel shingle roof over the old asphalt shingle roof. Thus you can get rid of the issue like tearing off your old asphalt shingle roof.
A superior quality steel roof can persist for near about 50 years or more. Asphalt roofs generally persist 20 to 30 years on the basis of the installation and shingle quality.
If you plan to set up steel over asphalt, it will be better to apply a steel shingle system in place of costly standing seam steel. Within a standing seam roof, there are long, single panels which direct perpendicularly all the way from the eave to the ridge. On the other hand, steel shingles belong to small panels which are arranged in horizontal rows similar to other shingles.
Superior quality steel shingle systems are installed over a framework of 2x2s. This framework offers the following useful benefits.
• It can resist winds up to 120 mph devoid of any destruction as the frame is screwed directly to the rafters as well as the interlocked shingles are screwed to the frame.
• The frame consists of a flat and straight surface though the shingles are severely curled or the roof ridge is curved.
• The frame produces a ventilation gap that can resist ice dams in the winter as well as chills the roof together with the house in the summer. To drain through the roof, holes are sliced in the old roof over the soffit, which brings air via the soffit vents underneath. Chill outside air then moves below the shingles to the vented ridge, extracting moisture and heat.
