Most companies that offer ice dam removal in Haverstraw do not offer fixed pricing for their services. This is because the price of a quality Haverstraw ice dam removal service depends on the size of the ice dam to be removed. Because ice dams are usually buried beneath layers of snow, their size can only be determined after they have been removed completely. The cost of ice dam removal in Haverstraw can also be affected by the kind of roof that you have. Each roofing material has its unique needs. Metal, glass, and slate roofs are quite dangerous and difficult to climb during winter so special tools and equipment pieces are needed to remove ice dam from them. This can greatly affect the cost of the job. The pitch of the roof also determines how difficult or easy it would be for an ice dam removal professional to climb or walk on the roof. The steeper the roof is, the costlier the service will be.
