Not a lot of amateurs will tackle a flat roof project, whether it’s a garage or a factory. Flat roofs require specialized knowledge, equipment and skills. These are particularly difficult for the homeowner to tackle. There are issues with flashing, seams, vents and ridges. Also, completing the drains can be difficult. For these reasons, it is recommended that professionals complete your flat roof. However, many amateurs will tackle a shingle roof. This is often triggered by a leak or when the owner's insurance company recommends action.
Some homeowners believe that to shingle a roof, all you need to do is to buy some shingles and nail them on the roof. However, a great deal has changed in the shingling industry. Old shingles have to be removed and disposed of in an environmentally safe many. Any rotten roof sheathing needs to be replaced and water shield, felt and flashing installed. At the same time, the peaks and valleys need to be completed and proper ventilation installed.
