Roof Replacement in Dallas
Roof replacement in Dallas, apart from being critical in home maintenance, is often one of the most misunderstood in this area. You should realise that there is a considerable difference between a professional roof replacement contractor and an installer of shingles. Shingle installers concentrate on the replacement of roof shingles and do not know much or take care with the structural problems involved in roof replacement. Needless to say, these shortcuts can cost real money in terms of steep energy bills and leave the homeowner with moisture and maintenance problems in the future. In other words, inferior quality and improperly used roofing materials combined with bad workmanship can be really expensive.
The existing roof material must be removed right down to the plywood. The existing coverings on the roof, irrespective of whether they are shingle, slate or tile should be completely eliminated down to the existing plywood for sheet roof deck. You should also keep in mind that shingle manufacturers specify that if shingles are fixed over any kind of roofing material, the warranty cannot be enforced and will be voided. This is why it is so important for the roofing contractor to follow the product specifications laid down by the manufacturer for roof replacement. Existing flashing should also be eliminated down to the sheathing on the roof deck because it is impossible for anyone to tell what could be hidden under the old flashing. Damaged and rotten wood hidden in these areas needs to be replaced because future structural problems can occur if they are left in place.
The roofing tar paper will probably be removed by the roofing contractors to enable them to do a thorough inspection of the existing surface of the deck before installing the underlayment and the shingles. The nails holding roof sheeting in place should be properly inspected and the sheathing fastened again where necessary before commencing the roof replacement. Damage and rotten wood must be removed and replaced because fastening onto rotten or soft wood could cause the shingles to shift result in in the development of leaks in your new roof after installation. Some form of underlayment should be fixed over the roof sheathing before laying roof shingles and the most popular are tar paper or titanium underlayment. They are both adequate but titanium is a better reflector and the increased costs are offset by the warranty or guarantee if the replacement shingles fail for any reason whatsoever.
The ice and water shield should always be installed at the gutter end lines on any roof, but sometimes it happens that these ice and water shields are installed incorrectly. The space between the fascia board and the roof must be sealed with a gutter apron for a seal cap for the ice and water shield to work properly. Finally, continuous ventilation is a must because improperly ventilated roof systems will cut down the life of your roof shingles. A proper replacement should include continuous ventilation at the peak on the roof and at the beginning of each shingles starter area. This is particularly important because many houses do not have a soffit area where airflow can provide ventilation in the attic space and then emerge through the roof peak ventilation area.
