Roof Design Considerations for Shingle Roofs  


Tools Required

As well as your shingle materials you will need a tool kit comprising;

  • Tape measure
  • Marker & chalk line
  • Sharp knife
  • Straight edge
  • Small pressure roller
  • Cartridge gun (to apply Xtra-Seal Sealant)
  • Soft headed broom & brushes
  • Hammer
  • Wood saw

The use of personal safety equipment – especially gloves, boots and protective goggles or glasses – is recommended.

Consider the Weather

Before beginning to lay your roof always try to ensure that the weather will be dry and warm all day.

Temperature Awareness

During colder weather the shingles and shingle strip may be susceptible to cracking when bent or formed around details.

It is recommended that the shingles and shingle strip are stored in a warm environment for 24 hours prior to use. If it is necessary to work in cold weather, then gentle warming with a hot air paint stripper or similar (not a naked flame) will help reduce any cracking when working the shingles or shingle strip. If temperatures and weather conditions become extreme it is advisable to postpone the work until more favourable conditions occur.


Anderson Bitumen Roofing Shingles and associated products are compatible with most materials normally associated with roofing structures. However solvent based products and timber preservatives containing solvent may soften bitumen and should be avoided, special care should be taken when choosing treated timber for use in the roof structure.

Material Storage

Store materials in a dry and warm location. Rolls must be stored on end on a clean, level surface away from direct heat sources.
Shingles should be stored flat on a clean, flat and level surface away from direct sources of heat. We recommend that material  is stored in a warm location and taken to the roof as required.

Health & Safety Considerations

Construction or replacement of a roof means that you will be working at height and as such personal safety and prevention against a fall must be considered a priority. Roof refurbishment can be complex, is always high risk and demands careful planning. For detailed information relating to Safety in Roofwork consult HSE publication HSG33.

Always consider the following:

Safe access to the roof – ladders should be of the correct type and height, in good condition and securely fixed to prevent movement or slippage.
Edge protection – working at height requires prevention against falls by providing adequate roof edge protection or independent scaffolding.
Weather conditions – consideration must be given to working in adverse or windy conditions. A sudden gust of wind can lead to loss of balance, particular care should be taken if handling large sheets of plywood or roofing materials.
Material handling – well planned material handling has a significant impact on roof safety and care should be taken when lifting and moving materials to avoid injury.
Getting materials to the roof – reduce the amount of travelling to the ground to collect materials by using lifting appliances such as a gin wheel or scaffold hoist.
Falling materials – precaution should be taken to avoid materials or tools falling from the roof causing injury to people below.
Cables and pipes – always check and identify pipes and cables within the roof structure before work commences.
Overhead cables – check that any cables passing overhead will not interfere with operations, taking particular care when moving metal ladders etc.
Personal protection – always wear the right protective equipment ie: boots, gloves, goggles, hard hat.
Protection of work – adequately protect work in progress.


Inspections only take a matter of minutes and involve a routine look at the roof condition. It is important to check the gutters and down pipes, flashings and roof edge details as well as valley, hip and ridge details.
In Spring it is important to check gutters and down pipes are not blocked by fallen leaves which may cause the gutters to overflow.
