Roof Survey and Inspection
What is a roof survey?
A roof survey and inspection is a snapshot of the condition of your roof. The survey and inspection, done at least yearly and after any storm, will help you identify problems early. This can prevent more expensive problems later on if repaired before they cause further damage or leaks.
A roof survey will also help you determine if your roof is sized, designed and constructed effectively. You may be able to make some repairs or do regular maintenance that can save you costly repairs in the future.
What should I be looking for in a roof survey?
Look for missing roof tiles, curling roof tiles, raised nails (from storm or hail damage), or any other damage that can allow water penetration. Also, keep an eye out for excessive moss on asphalt roof tiles, split or cracked shingles, raised nails (from wind damage), corroding flashing or flat spots in roof tiles granules (indicating weight).
Check for missing, bent or broken gutters and downspouts; clogged rain drains; and bent, broken or improperly installed flashing.
Look at the condition of your roof drain tiles to ensure they are draining water away from the structure, not allowing it to collect behind flat roofing membranes. If you have membrane-type shingles or tiles, look for worn spots where water could be getting past the slates and collecting behind the roof tiles.
In addition, look for low spots and valleys in the roof. Water can pool in these areas and lead to leaks. The same holds true for checking out your foundation (if you can get up on top of it) and checking for cracks.
Is a roof survey necessary?
If you are having problems with your roof, it may be time for a survey. Surveyors look at the whole structure of your home -- not just the roof -- to make sure there are no underlying causes of the problem you are seeing with the roof. For example, if you have shingles missing or curling up on one part of your roof, a surveyor might see that the gutters are improperly sloped. This could channel rainwater from the rest of the roof to just a couple of roof tiles.
If you do not have any obvious problems with your roof, a survey might still be in order if you have something valuable at stake -- such as a rental property.
How would a surveyor inspect a roof?
Although this varies somewhat based on the type of roof, a surveyor will probably not actually walk on your roof. Instead, he might take pictures from the ground with a telephoto lens to get details of gables and valleys. From another building nearby or by using binoculars, he might also inspect your roof. If your home is several stories tall, the surveyor might use binoculars to inspect your roof from a distance. He might also check out your gutters and downspouts.
A roof inspection is really no different than an on-site car or home inspection. Of course, roofs are trickier to get to because they are at the top of a house. So, be prepared for your surveyor to get off track, climb onto your roof and need to take more time than you expected.
What is involved in a roof inspection?
The first thing your roof inspection entails is an evaluation of the pitch or grade of the roof. Is this pitched roof low, medium or high? The pitch is important because it can lead to certain problems.
If you have a pitched roof, the surveyor should also inspect the slant of your gutters because this could affect how well they drain and ultimately whether or not they need to be repaired or replaced.
In addition, he will look at the material that your gutters are made of so he can determine whether or not they are original to the home. If they are, this helps to keep the value up on the house because buyers looking for older homes will want to be sure that what they are buying is still in good condition.
The next thing your roof inspection includes is an examination of material on the roof. If there are several layers, it is important to know which one was put down first because this may affect how long it will last before some kind of repair or replacement is needed. It also helps to determine if any of the original material can be reused instead of replaced with new products.
The size of your skylights and their condition are also important to know. If they are small, it may be time for larger ones if the light in the house is insufficient, which can make it harder to use certain rooms. The number of roofing layers and their thickness also matters along with any problems that these layers may have.
How much does a roof survey cost?
The average cost for a roof survey is around £250 to £500. The price may be higher if a skylight needs replacement. A clear picture or a video is necessary. It may cost more if you want a copy of the survey for your records. The height of the property and accessibility also have an impact on the cost. Some companies offer drone surveys that are efficient but may be pricey.
What does a roof survey include?
In general, all aspects of the roof are checked. If you are selling, this is usually needed when submitting a survey to the mortgage company. This ensures they know what needs to be fixed before they finance your house. The following things will generally be included in a roof survey:
* Standing and fallen debris such as leaves and branches
* Conditions of the guttering
* Chainage distances from the survey point to where each roof plane meets a vertical surface, such as chimneys or walls
* The pitch of the roof
* Any previous repairs and their condition
* Evidence of water penetration through the roof membrane
Are roof surveys free?
If you are trying to sell a house, a survey will help to achieve the best price. Even if you're not, a roof condition report is vital to find out what work needs doing and can save you money in the long term.
What work does a roof survey include?
Generally, a roof inspection consists of three main areas: an overall exterior check, a gutter inspection and a roof penetration check.
The following points should be considered:
* Exterior inspection:
o Location and condition of flashings and seals around chimneys, skylights and vents
o Condition of all exterior components such as gutters, fascias, soffits and gables
° Guttering, downpipes and water butts
o Condition of roof covering, flashings, ridge tiles and valley tiles
o Staining or efflorescence on the exterior surface of the building.
* Gutter inspection:
o Location of gutter supports and fixings
o Exterior condition of gutters and down
