Roof Replacement in Keller
If you are considering roof replacement in Keller, here are some things that you should know about. Many owners of buildings and executives in facility management have had to deal with unscheduled capital expenditure because of repairs to roofing. Many of these problems are related to water infiltration and can be avoided by developing and following a systematic scheduled maintenance program for the life of any roofing systems. Even with the appearance to a complete maintenance program, the decision to repair or recover or replace an existing roofing system will have to be made at some point in time close to the end of the expected service life of the roof.
This decision will have to be made after taking into account many factors such as the location, the type of system presently used, costs, construction schedules, requirements of occupants and long and short-term uses of the property. It is possible to identify some of the physical issues which have an effect on roof performance in general terms, it is best for the appropriate decision to be made on a building by building basis. The first step which needs to be taken before beginning the process of decision making is to estimate the remaining service life of the roof. This estimate is based on factors which include water infiltration, moisture trapped in the underlying insulation, the movement of aggregate across the roof, the slippage of bituminous membrane and how brittle the single ply membranes are. An educated design professional can, by investigating the existing system, answer questions for the owner and provide comment on related technical and code issues. The professional may also be able to eliminate assumptions which are misleading or false such as the incorrect attribution to water when the water is actually entering the building through the adjoining exterior walls.
Repairing an existing roof membrane or deciding to replace sections of the roofing system cannot be if the damage leading to the need for repair is due to long-term exposure or the advanced age of the roof. If the deterioration is substantial, the use of a maintenance coating is unlikely to solve the problem. Replacing flashing may eliminate a specific source of water leakage but the extensive replacement of components in isolation can never be cost effective and the interface of the new components with the old ones can provide inconsistent quality. If there is a mistake in identifying the source of water, the roof repair may be attempted several times without identifying the location of the leak. As the roof continues to leak, there will be more interior damage and the cost of repairs will just go up. In any case, the cost of
temporary solutions cannot be justified and it may be better to recover or replace the roof.
One procedure which should be followed in any roof repair is an investigation for the presence of moisture below the roofing membrane. The membrane may appear to be in good condition on the surface but the presence of water below the surface from other sources could create problems which can only be solved by the removal of a membrane which is apparently in good condition. In any case, the source of moisture must be found and fixed otherwise the conditions may return after the membrane has been replaced.
