A St. Louis slate roofing expert can help you determine if your roof is in need of repair, or if a complete replacement is necessary.
A slate roof is known for its aesthetic beauty, longevity, and durability. A slate roof adds a touch of aristocracy to a home and can last for as long as hundred years. However, like everything else, slate roofs are also subject to wear and tear and may need either maintenance or replacement over time.
Keeping the costs involved in mind, re-installing, or completely changing a slate roof often takes a lot of budgeting and consideration.
A St. Louis slate roofing expert at Duration Construction will be able to tell the type of slate used on the roof and determine which tiles need to be replaced. The following may indicate that the slate roof is ready for replacement:
- Moisture patches and active leaks in the attics and the rafters, the first and second floor rooms are clear indicators. Aged tiles become brittle or soft and start absorbing moisture. Over a period of time, this moisture can rot and cause excessive damage in the top areas of the house. Moisture damage generally indicates that the roof tiles are beyond salvage.
- While examining the roof, one should look around the areas of leakage. Are there any leaks around the metal flashings, valleys, or gutters? How many leaks are visible? If there are few, replacing the metal flashings and the gutters may suffice. For more extensive damage, replacing the roof will likely be advised.
- Look at individual tiles through a pair of binoculars or from atop a ladder. Take note of the number of cracked, pockmarked, slipping, or missing tiles. Look around the general area. Is the damage confined to one area, in more than one area, or does the entire roof have such tiles? The extent of damage to the tiles will help determine the requirement for a roof replacement.
- While checking fallen tiles, it is important to check for firmness. This can be done by tapping on them with the knuckles. A resonant sound indicates the good condition. In such cases, the metal fasteners could be the culprits requiring replacement rather than the tiling. However, if dull sound issues from the tiles, the tiling may need replacement.
- To understand when a roof needs to be replaced, a percentage estimation of the damaged roof should be conducted. In general, the estimation is done in each section of the roof. Any section that has more than twenty percent of the roof tiles damaged, the tiles will likely need to be replaced. If such damaged tiles are seen all over the roof, then it will likely best that the roof is replaced. However, it is also important to note that if more than ten percent of the total roof surface is damaged then it may be wiser to replace the whole roof rather than to try and replace only damaged tiles. The risk of damaging other neighboring tiles increases, eventually requiring a complete roof replacement, making the whole process more expensive.
