Wilmington Roofing: Article About Inspecting The Exterior Of A Roof
A Wilmington roofing professional can do a thorough exterior roof inspection to determine if there are issues with the surface materials, flashing, gutters or eaves of a residential roof. If so, depending on the extent of the problems, either repairs can be made or the entire roof can be replaced.
Roofing inspectors will use binoculars to closely inspect the surface of a roof. They are careful not to walk on roofs any more than necessary. Special care is taken when walking on slate or metal roofs so that the surface materials are not damaged. The southern exposure of any roof gets the most sunlight, so it's crucial that it be checked carefully.
Different types of roofing materials have different types of problems to look for. Asphalt shingles will curl up where the wind has been able to penetrate beneath them. Bald spots will appear where exposure to the elements has worn away mineral granules.
A way to test how effective aging asphalt shingles still are is to pinch off a corner and then examine the interior of the piece. If it is a dark, this means that the shingle is still capable of shielding the house from water. If it is gray, it means that the shingles have lost their effectiveness and will only absorb water like a sponge rather than repel it.

If this is the case, it's time to replace the entire roof.
Wood shingles will warp when they have been exposed to the elements for too long. They will also develop cracks. Any spots where nails have become exposed are potential entrances for water into the attic. As far as wooden shakes go, it's time to replace them when they crumble under foot.
Metal roofs usually last at least 50 years and do not leak. They can become warped, bent and dented, however, and roofing inspectors will look for this. They can also become corroded, especially in areas near the seashore where there is a lot of salt and moisture in the air.
The felt underlayment of slate roofs will often wear out before the slate itself. Roofing inspectors will remove enough slate to inspect the underlayment and see if it needs to be replaced. In these situations, the slate must be removed from the roof and then replaced after new underlayment is put down. Sometimes, individual slate tiles will be chipped or cracked and these can simply be replaced.
