And, of course, it’s understandable that most homeowners are not able to get on to their roofs and sort out these problems themselves.
Even for a roofing contractor, however, a leaking roof can be a challenge. Leaks aren’t often found in the same place where water is entering a property. So those working for the roofing company need to turn detective to identify the sources of leaks and the path of the escaping water accurately.
The National Roofing Contractors Association recommends regular roof maintenance and inspections so that future problems are not stored up.
It’s a good sign if, before an inspection, your roofing contractor looks around from ground level upwards and asks if there has been any extreme weather recently, or any falling trees, leaves or other debris, as well as any other kind of incident that may have damaged the roof, or if any satellite or cable work has been done. We always do this.
Have your roof inspected every six months, preferably once in spring and once in late autumn. Also consider checking following storms, snow or heavy rain.
Clogged gutters and blocked drains are common causes of leaking roofs. Make sure you clean yours regularly.
It’s also well worth being aware of the most common places roofs leak. These include:
• Where roof tiles are missing
• Wall step flashings
• Low spots or ‘valleys’ in the roof
• Flashings around vents, skylights and chimneys
• Plumbing vent flashings
Don’t try and go up on the roof yourself, but get a robust ladder and some binoculars and look for problems and irregularities before calling in the professionals.
Clearly, the earlier problems are dealt with, the easier they will be to put right.
