From the layman's perspective, installing a roof could be as simple as affixing shingles across a surface. However, roofing is actually a complex installation process with several checks and layers to its complete structure. A Kent roofing professional must work through several steps to ensure a roof won't leak for many years.

The roof deck is the bare plywood surface all roofing materials are attached to in almost all structures. However, it is difficult to quote a roof deck accurately through estimation processes because it's layered with roofing materials. As contractors remove the old shingles, they can see the entire deck. Some areas could be damaged by old leaks, for instance, requiring new plywood before roofing can be installed. Although most contractors add in some deck repair within the original roofing contract, they may have to add more costs if damage is extensive.

Shingles aren't attached directly to the deck because an underlayment must be installed first. This layer could be basic roofing felt or newer fiberglass-reinforced membranes. Its main purpose is to create another layer against possible moisture infiltration. Water can still enter the roof through shingle crevices unless the underlayment is properly installed underneath.

The roofing experts at Chase Construction of Kent WA can assist you with any questions regarding commercial roofing or metal roofing.

Homeowners will also see contractors adding straight lines to the underlayment after its installation. Shingles must be installed with straight edges, allowing water to flow easily down the surface without being hindered or directed into roof crevices. Contractors may draw lines on the underlayment using long lumber as a guide, or they may snap a chalk line for an instant straight line. If contractors aren't using a line as a guide for shingle installation, ask them about their protocols to ensure they're being as accurate as possible.

Each shingle should have up to six nails attaching it to the roof's surface. Although shingles appear to have small shapes, they often come as sectioned pieces requiring a lot of fasteners. Four to six nails is the average for most individual shingles, depending on their style and size. Shingles are relatively heavy and must withstand strong winds, so all these nails are crucial for proper installation. Even if one nail fails, the others hold the material in place.

Questionable contractors may create shortcuts in their work to hasten a project to completion. If possible, talk to previous clients about the contractor and see how well their roofs are holding up through the seasons. Roofs with little or no leaks reflect a strong installation strategy that homeowners want for their property.
