AMSTILL has been in business since 1974. We specialize in residential re-roofing, repairs, and structural work.
At Amstill Corporation, we believe that a sound roof is very important to the rehabilitation and maintenance of residential properties. We service the Houston metropolitan area from our offices and warehouse in west Houston.
Your Roof Application
When proposing a re-roofing job, the first step is to decide whether the existing roof should remain in place or be removed. Complete removal may be desirable in some cases and necessary in others. Tile, slate or hand split cedar shake roofs must be removed because of their irregular surface and the difficulty in nailing through them. Wood shingles may also be left in place and the surface modified where necessary to provide a relatively smooth base on which new asphalt shingles may be placed.
The main consideration, however, is the condition of the framing beneath the existing roof because new material installed on top of the old will add weight to the structure. The roof framing must be strong enough to support these additional loads, plus the weight of the roofers and their equipment.
Another important consideration is the fastening anchorage that the existing deck will provide. If the existing roofing has deteriorated to the point where it will not provide adequate anchorage for new roofing fasteners, the existing roofing material should be removed to the existing deck surface.
Another factor is the condition of the surface on which the new roofing will be applied. If the surface of the old asphalt roofing or wood shingles is warped, curled, or badly weathered to the point where providing a level surface for the new material will be difficult, it should be removed. If the surface is defective to the point where it will not provide adequate protection as an underlayment, if there are holes in the existing materials, or if there are depressions or sagging that indicate possible structural problems, the surface should be removed and remedial work performed on the underlying deck and roof structure.
