A roof replacement is the same as a roof repair except that a complete roof replacement is required when there are more than ten layers of shingles or tarps used on a roof. This may also include an attic ventilation system or vent and missing or cracked shingles or tiles. A roof replacement involves tearing off everything from the top to the bottom deck, replacing shingles and felt paper then putting on new felt paper.
There are different reasons why a roof replacement installed in Adelaide is called for. The most common reason is that there are too many layers of tarps or felt paper on a roof. If you only have one or two layers, it is not a big deal, but if you have ten layers, that’s where the rubber meets the asphalt. A roofing contractor can replace the shingles or felt materials and the replaced parts are applied to the tarps or felt. A newer roof can usually have three layers of tarps, three layers of felt paper, and then the roofing is applied. However, an older roof will have fewer layers and single roofing felt, or shingle will usually suffice.
If you have older shingles or felt paper, they can’t do a complete roof replacement. The best thing to do in this situation is to remove the worn shingles first. Be careful when doing this so as not to damage the underlying wood. Once the worn shingles have been removed, you can work on removing the damaged shingles with a hot razor blade. Be sure not to use an electric razor because the blade can cut the felt fibres and cause damage to the wood underneath.
Roof replacement installed in Adelaide may include replacing all or part of the asphalt roof. Many people are tempted to think that if their asphalt roof needs a repair, it only needs to be replaced with another asphalt roof. This is not the case, though. If the restoration of the top includes replacing the damaged asphalt roof with a new one, the cost of the entire project will likely be much higher than just replacing the damaged roof. The same rule applies when replacing asphalt roofs.
When the roof’s damaged portion has been replaced, you need to ensure that there is adequate underlayment between the new roof and the old shingles or felt board. Without the appropriate underlayment, the asphalt will not stick to the damaged portions of the roofing. Without the underlayment, the moisture from inside the home can seep into the house and cause further damage. The underlayment will also help prevent the formation of mould and mildew. If you plan to do the replacement on your own, you should choose a contractor specialising in old shingling or felt roof replacement installed in Adelaide. This will ensure that your new roof will be installed correctly and last longer than if you had chosen a different contractor.
