When homeowners need a new roof, but the cost is far out of their budget, they may be able to have a new set of shingles placed over the existing roof. Contractors who provide Roofing Services in Liberty MO can evaluate the structure and the roof to make sure this is a reasonable choice. Often, contractors refer to this type of project as reroofing in contrast to tear-off and new roof installation.
The cost is less because the workers don’t need to spend time tearing off shingles and there are no disposal fees for all that old material. Shingle manufacturers provide the same long warranty for reroofing projects as they do for new installation.
Certain conditions are imperative for this type of project to be effective and feasible.
Weight
First, the building must be able to support the weight of another layer of asphalt shingles. For this reason, roofers do not ever put a third layer on top of two sets of shingles. The weight must be fully supported even in the event of heavy snowfall. Large amounts of snow are uncommon in the Kansas City area, but the occasional freak snowstorm must be expected.
Even Surface
The existing shingles should not have a wavy or washboard appearance, or it will be extremely difficult for roofers to get the new ones to lay flat and even. The wavy surface detracts from the aesthetics of the home and could be a risk factor for leaks.
Condition of Roof
A contractor providing Roofing Services in Liberty MO wants to know the extent of any leaks the homeowners have noticed, as that could indicate damage to decking under the shingles. In some instances, however, there have not been any leaks. The property owners want to prevent future trouble as they have noticed shingle granules washing away into the gutters and out of the downspouts.
In general, a contracting company such as Ameristar Roofing & Restoration tends to be most willing to do this project if the existing roof is in relatively good condition but approaching the end of its expected lifespan. Visit Website Domain to find out about getting a roof evaluation.
