A roof can have many different issues that indicate it is time for replacing. The following are a few common problems that may indicate that you need roof replacement services instead of short-term roof repairs:
Moisture/Leaking– No matter the type of roof you have, if it leaks, you have problems that can be costly. Occurring for a number of reasons, leaks can be found on built-up roofs, membrane roofs, shingle, metal or tiled roofs. Due to age, weather, poor installation or improper maintenance, a roof generally has a long life and requires little from you. However, if you find signs of leaks in your ceiling, or moisture on the wooden underlayment of your roof, which can be seen from your attic on houses with raised roofs, then your roof needs professional attention and may need to be replaced.
Faulty Installation– An improper roof installation will increase the likelihood of problems and will reduce your roof systems useful life. This is true for structures with a built-up-roof (BUR) or membrane roof that is almost flat, or a beautifully designed roof with high-quality architectural shingles, metal or tile covering it. If the underlayment that forms a barrier between the roofing material and the roof decking system, or the flashing is improperly installed your roof may fail, long before it should. Even the best of roofs will fail over time and a complete roof renovation is the best choice to make when repairs no longer hold the onslaught of the weather at bay.
Poor Maintenance – The roof of a home is often one of the last items a homeowner thinks about unless it is leaking or visibly in disrepair. This neglect can cause issues. Many newer roofing products have warranties that may be voided if their maintenance schedule is not followed. Issues like a slipped piece of flashing, ponding water, and pitch pockets are evident with a visual inspection, even if you don’t know much about roofing.
Gutters –Clogged gutters can damage the wood they are attached to, cause mold build up along the roof edges and weaken the structure of your roof if left unattended. If your roof shows a buildup of mold or moss it should be cleaned to extend its life. Cleaning out your gutters and making sure that water is being directed away from the eaves and edges of the roof is one of the best forms of roof maintenance you can perform. For homes that have roof damage due to a poorly maintained gutter system a replacement of the roof may be necessary.
Ponding Water – This can happen to all roof types and ponding water compounded with UV rays of the sun can adversely affect your roof. If you have water ponding on your roof, it will eventually cause damage to the membrane and base structure of the roof if left unattended. Replacing a roof may be necessary if your roof has ponding water that roof repairs have not corrected.
Damaged Flashing – Roof flashing can be made from galvanized metal, copper, stainless steel or less expensive plastic. Placed in the valleys of the roof, around chimneys and dormer windows, flashing directs water toward the gutters. It is estimated that 95 percent of roof leaks occur at flashing points. This is so for flat roofs with BUR, membrane roofs or conventional pitched roofs.
