Roof repair is expensive work that requires the expertise of a skilled professional. Unfortunately, and for many different reasons, roofing projects may be carried out poorly, leading to visual inconsistencies or even catastrophic structural mistakes.
The most common sign of a poor roofing job is that the previous problem has once again returned, even after you've had critical work done. But there are plenty of other red flags that don't require an expert's eye to spot.
If you've had any suspicions, doubts or distrust surrounding your lastest roofing job, Roof Giant give you some of the most glaring signs to look out for...
How often do you look at your roof?
If you've ever cast an eye over your roof and noticed that it has an uneven quality or lacks uniformity, then this could be a major indicator of poor workmanship.
Look out for different coloured shingles, sloping roof lines, mismatched materials and any evidence of cutting corners; e.g. materials that vary noticeably in quality and consistency.
Missing Drip Edges Or Roof Underlayment
Noticing leaks, mould, staining or similar problems?
Check that your underlayment or drip edges aren't missing. Both these elements are used to protect your roof from water damage and increase the longevity of your roof.
To find the underlayment paper, peer under the shingles, and to find the drip edges, look under the edge of your roof for the layer of metal between the underlay and the shingles, protruding over the gutter. If either of these elements appears to be absent or even if your drip edge doesn't seem to be attached or positioned properly, then your roof may have been carelessly constructed.
Evidence Of Poor Nail Use
Incorrect roof nails and haphazard roofing nail technique are both big signs of a bad roofing job on a smaller scale.
Roofing nails are made for purpose and are designed to suit very specific components of your roof within the overall job.
Look out for...
Old Flashing Has Been Used
Any competent roofer will always use brand new materials (otherwise a high quality end-result can't be guaranteed) and won't cut corners replacing or reusing any old or existing flashing.
Even if the re-used flashing appears to be in good condition, look closer.
Using flashing again on a new project may result in worrying issues such as water leaking into your home through chimneys, roof valleys and similar weak points, leading to expensive repairs down the line.
Make sure you always ask a roofing professional if they plan on using new flashing and check the quality of the flashing once the job is complete.
